<< A question - why does the alternator need a switch that is separate from the master? I cannot think of any time when I would want one without the other. You would always want the battery switch on if you had the alternator on, but in the rare case that the alternator "runs away" and starts putting out excessive current you can shut it down without shutting off the main buss. That's why the "Cessna" master/alternator switch (the double red one) is keyed so the master can be turned ON by itself, or the alternator OFF by itself, but not the other way around. Incidentally, I was at the first flight of Ken Hitchmough's RV6A, and I have since been for a flight in it - it is fabulous.

The builder's manual includes a list of all the tools needed, and John Hovan's page links to a list of all the tools you could possibly use. Somewhere between these two is the probable reality, dictated by your money, skills, and preferences. I ignored Avery's 'kit' and made up my own (Avery will give you discounts for spending enough money), based on the tools I needed to complete the tail kit. Not only did this let me get started with less money, but also left me with fewer tools to get rid of should I abandon the project. However, the bug has bit, so I've bought the rest of the tools I need. Also, what you need depends on what you already have. In short, you'll have to decide for yourself what to buy. IMHO, the more power tools, the better. PatK - RV-6A - Left aileron assembled and ready for primer. ________________________________________________________________________________

I don't like it, because as you say, the 'reversal' when trimming, but I haven't been able to figure out a cure for it. My trim tab has about 3/8 to 1/2 inch play in it, and as you move it, you can see the cable moving back and forth, that is why I feel that the slop is in the cable/vernier part. If I reverse my trim desire in flight, I just automatically rotate about a full turn and a half before it takes a bite on trim. If you come up with a cure, let us know.

I believe 30 deg up and down is called for. I'd build and place the horn to spec. One of the Rockets I built had this option, and it didn't seem to have enough trim on short final (these birds are nose heavy anyway). I adjusted the tab for proper travel in the nose up direction, and this left less nose down. Still no good, so I made up a different tab, similiar to the tabs on a V-35 Bonanza (extended chord), and this fixed the problem.

I know everyone must think this has been beaten to death by now, but I had an idea I thought I'd share. The instructions say that one could use Proseal instead of RTV to strengthen the surfaces if one had a builder close by with some to spare. I'm thinking that I will put Proseal between the stiffeners and the skin as well to strengthen this area. I understand it's quite a good adhesive, and this seems to be an application where the extra strength would help. If I can't scrounge some, I'll order it from Van's. By the way, on drawing 7PP on the RV-8, it looks like the clearance is about 5/16 between the stiffeners and the trailing edge at the closest point when you transfer the scale dimensions.

The GPS system is being augmented with a system of ground monitor stations, a few master stations (I think 2 of them), and the use of maritime satellites (INMARSATs). The ground monitors will monitor all of the satellites for proper data, relay the information to the master stations, which condense the data and relay it to the INMARSATs for retransmission to all users (GPS receivers). The idea is that all GPS receivers will be able to receive system integrety messages (eg. Satellite #17 is transmitting bad data, don't use it). Additionally (I think), the INMARSATS are being fitted with GPS transmitters, so that they can transmit the standard GPS data for use in navigation, thus increasing the number of satellites in the whole constellation. The whole thing is called the Wide Area Augmentation System, or WAAS. That is all. Hank Eilts RV6 tail under way. ________________________________________________________________________________

I have a Sensenich 70CM prop installed on my RV-6. On Sensenich's WWW page under FAQ, the question about occasionally exceeding the 2600RPM restriction was raised. Sensenich's statement is simple: You absolutely must not exceed this limit. With this in mind, I calibrated my ISSPRO mechanical tachometer with the aid of an electronic handheld tachometer. The mechanical tachometer read low in all ranges, from 50 RPM low at idle to 150 RPM low at a static RPM of 2250. Interpolating from this, I will redline my tachometer at 2400 RPM. I also hope to repeat that test in flight at cruise RPM, and will repeat the calibration once a year to assure that there is no change. My ISSPRO tachometer was purchased from VAN's option catalog.

Some other items that are great to have: a hand held belt sander. This is much faster than files. I also use the belt sander to smooth the rough shear edge before I use another item that is handy, the double edge deburring tool. You'll need a flat, smooth piece of steel for back riveting stiffners (back rivet plate). The jig fixture brackets are handy for speeding the project along but at $ 21.00, it would be nice to borrow a set from your fellow builders (see below). The right angle drill attachment for $39.00 will come in handy. I also use my Scotch-Brite cutting and polishing kit quite a bit. Buy the same diameter sandpaper discs for use with the same mandrel. A cheap right angle air drill is handy for use with the above. I use both the medium and fine 6" Scotch Brite deburring wheels, heavy work on the medium--finish off with the fine. You'll need some Sharpie marking pens. Some stuff you could save some money on: drill stops, wrap masking tape around your bit, instead. Fan space rivet tool, the new kits are predrilled and there is a cheaper way to accomplish the same thing, anyway. I see the kit comes with a straight flush set. A lot of builder's are using the flush swivel set and this does virtually eleminate smileys. I have and use both but have been using the straight set more and more as I feel it's smaller head transmits more force to the factory head and less to the surrounding area. It seems like I get a better job of riveting done with the straight set, maybe just my imagination. The swivel set is probably a good idea if you're bucking and have someone who is less experienced driving. (I bought the swivel so my wife (and me) would be less nervous) If I'm directing this reply to Mark, if you'd drive to Lexington (and bring, you know what) I'll give you some further pointers, we'll practice riveting and I'll give you a RV-6 ride.

Van has two styles of wheel fairings. One reputedly offers a speed increase of 4 or 5 MPH over the other. It is closer to the ground and more susceptible to damage. For that reason I chose the other.

I think limited advertising on this list is fine, so long as it meets two criteria. 1] The item or service is of direct interest too, and specifically for RV builders and pilots. 2] It is honest and free of scams. If someone on this list has developed something that can help other builders why not talk about it? And, if it costs money, so what? Everything costs money. I don't expect someone to build a tool or a part for me for free. Perhaps if that person was my neighbor, I'd invite them over for dinner as a token of my appreciation for the time they spent on my part. But obviously, if that person is 1000 miles away, that invitation might be inconvenient. So instead, I send a few buck so he can get himself a meal in his own town. What wrong with that?

Subject: Re: RV-6a canopy type
<< Before we are forced to make a choice we may regret would you experienced RV builders comment on sliding versa clamshell type canopy. My brother Bob is the one that needs to make this choice and we have discussed pros and cons. It seems that trader plane ads coming from prsopective purchasers of pre-built RV-6 or 6A specifically desire sliding type. Input please..... >> Oooh boy, I bet this will be a veritable can o' worms! I considered posting this privately, but I'm sure others are sitting on the fence as well, so here's my .02: Mine is a slider and I wouldn't even consider building a tip-up. My main reason is cosmetic. I just LOVE the way the slider looks and the silky-smooth operation of it. It's very fighter-pilot-esque, and oh so jaunty (not to mention a nice breeze) to taxi with the slider back and your arm on the side rail. As for the cons, the instrument panel can only be accessed from underneath once the top skin is riveted on. I believe it's also a little trickier to build. These are MY opinions. Lots of people like the tip up - I just like the slider better. Happy decision-making, Ed Bundy ________________________________________________________________________________

Date: Sep 09, 1996
Guys -- A friend of a friend destroyed his Bonanza in a microburst incident 2 years ago. (Neither occupant was killed.) He has the option to purchase the wreckage from the insurance company at what *sounds* like a pretty good price. He would do so in order to salvage some of the avionics he wants for his replacement plane -- like the StormScope -- and would sell everything else. I would *think* this would be an opportunity for me (or other listers) to pick up a whole ton of items, such as: 1. Lots of radios and such 2. Engine instruments 3. Heated pitot tube 4. The electrical system parts -- the bus, master switch, other switches, etc. 5. Exterior lights -- strobes and such 6. Misc stuff like Hobbs meters, etc. However, I don't know how likely this stuff is to survive this kind of accident. It occurred during missed approach -- they bellied into the ground, nose high, full engine power, and totally destroyed the aircraft. The seats, occupants still attached, separated from the fuselage, for instance. I also don't know how I would be able to test if it worked, what the damage to stuff is if it sits for 4 years (2 years since the crash and another 2+ years until I'll be in the air), or what fair prices might be. Comments? If he buys the wreck, should I do a followup post with the available items? -Joe -- Joe Larson jpl(at)showpg.mn.org 612-591-1037 Showpage Software, Inc. http://www.wavefront.com/~showpg 14190 47th Ave N.

> I don't know whether this is true or not, but my instructor said > something about how a few pilots had pulled the wings on his type of RV > (it's either a 3 or a 4) prior to some structural modifications. I didn't see any other responses to this, so I'll toss in what I know. Approximately a year ago, an early RV-3 was destroyed in flight. The plane in question was being flown in close proximity to Van in one of the factory planes at the time, making the incident even more poignant. >From bits and pieces I have heard, and some of this information might be confusing multiple incidents or just plain wrong -- please don't jump all over me for that -- here is some info. 1. Early RV-3s had a fairly low stick force per G factor. That is, as you added Gs by pulling on the stick, there wasn't a lot of force telling the pilot what he was doing. This increases the ease with which one overstresses the airframe. 2. RV-3s (maybe only early RV-3s) have been shown to fail earlier than structural analysis suggest they should. Van has identified this as a problem and provided a fix free-of-charge to all registered RV-3 owners. 3. The pilot of the failed -3 was, if my info is correct: a. NOT the builder and relatively new to the -3. b. A medical examiner for the military, used to high-G maneuvers riding in fancy military hardware. A 9-G turn wouldn't be unusual to this sort of person. To the best of my information, this is the only known RV- in-flight breakup, and it was an early RV-3. The contributing problems in the -3 do not appear in the -4, -6, -6A or -8. -Joe -- Joe Larson jpl(at)showpg.mn.org 612-591-1037 Showpage Software, Inc. http://www.wavefront.com/~showpg 14190 47th Ave N.

I do like Savier's wheel pants, they LOOK fast. Saviers do appear to me to be a fair bit thinner and lighter than Vans. BUT... since I plan to USE my rv, i.e . fly it into grass, dirt & gravel strips, I'll probably pass on the fancy wheel fairings and small tires.

Subject: Where to put the electrical conduit in RV-6AQ
I'm looking for advice/experience regarding where to locate conduit in my RV-6A (quickbuild). I bought 50' of Van's conduit (light weight, ridged, approx 7/8" OD) which I intend to use to house electrical lines running thru the wings (I gave up on the small factory-installed grommets because all the lines I need to run won't fit). It seems to me that the simplest way to run the conduit is right down thru the lightning holes in the main ribs (behind the spar). The largest lightening hole looks like a good candidate -- it matches the hole already cut in the fuselage right behind where the main spar will go. I need to make sure, however, that the location I pick doesn't end up interfering with the aileron pushrod that also runs thru the large lightning hole. Is there a location (top, bottom, front, or rear) inside the large lightning hole that would accomodate the conduit without interference from the pushrod? Should I drop back to the second lightning hole behind the spar, and open up a new hole to the fuselage? Thanks for your ideas and experience.

I don't agree that this is a good idea. If we were building Murphy's and some of us were doing biplanes and others were doing SuperRebels, maybe.

Tim, I would be very leery about putting anything "in" the first big lightning hole in the main ribs. If anything came adrift in here it would be muddled up with bell cranks, pushrods etc. I drilled a hole in the metal between the top of the spar and the first lighting hole. This is a location I have seen successfully used in completed aircraft. There has been some discussion about alternate locations and the archives may be worth a look. A useful tip (from the archives) is that a piece of dental floss with some rag tied on the end can be blown down the tube easily with compressed air to provide a pull through (and leave one in place).

The theory is that if the filter gets totally clogged or a bird goes down the thingamy, then the reduced pressure will pull open the flap and supply air to the carb.

Tim: One of the problems with Van's tubing is that you have to have it in place when you rivet on the last wing skin surface. If you've already run the tubing down the wing, it may be in the way when you rivet on the skins. I used a piece of thin wall PVC tubing that could be slid into the wing after the skins were riveted in place. I positioned it near the top skin behind the main spar. Some people are putting this tube in front of the spare so that they don't have to feed the wires throught the spar box inside the fuselage.

The regs say that you need something like 20C rise in ambient for alternate air ( They don't say under what conditions). I found that the lower cowl air was not sufficent as alternate air in IFR conditions, so I put a muff around the cross-over pipes just above the airbox. a short hose is used between this muff and a new hose nipple on the airbox. Early tests still indicated that the air wasn't hot enough, so I wrapped a door sping painted with high temp paint around the pipes under the muff to increase the surface area. A temp probe in the airbox now indicates the needed ambient rise in temp. I've not seen any indication of icing since. > >I'm inclined to want to plumb warmer air from the Vetterman carb heat muff to >the alternate air trap door to melt that ice lickety split, but how is this >to be done effectively.

If that little birdie can get in far enough to block the inlet and carb heat flap, you have a problem. The same is true if you ice your filter on a fuel injected engine where heat is not supplied to that flap (alternate air). I have a problem believing the icing bit. A local inspector did not, so one local builder had to put another inlet door between the filter and the servo inlet. This will take care of the birds too. Not wanting to get caught at inspection, I put a door on the oval plate that bolts to the servo (part of FAB). There will be a light spring holding the door closed. Should the need arise, the pressure differential between the cowl and the intake will open the door. Setting that spring up so that the door is normally closed promises to be fun. The area of these alternate inlets may be less than the carb or servo throat. I figure that if you are in a position to need these things, a slightly starved engine will be enough to melt the ice or get you and the unfortunate bird home. Once again it is nice to have an aircraft that performs as well as the RV's do.

It was free and it's a lot better than just using a basic email alias, but it gives me gray hairs. The problem you were having is that you were listed as follows in the RV-List address list: MIKE_PARKINSON(at)HP9061.desk.hp.com (Mike Parkinson) Unless you unssubscribe with that exact string, majordomo doesn't have a clue as to who you are. I notice that the address you are signed up as bears little resemblence to the one you sent me mail from... ;-) Your message to me about this has a From: line that reads: MIKE_PARKINSON@HP-Australia-om1.om.hp.com In the future, here's how you can more easially unsubscribe from a majordomo run email list like the RV-List and Zenith-List. Step 1: Send an email message to "rv-list-request(at)matronics.com" and put the word "who" in the body of the message - no subject and no other text. Majordomo will send you back a list of all the email addresses currently subscribed to the List. Best of all, the address will be the exact syntax you will need to successfully unsubscribe. Step 2: Find your name/email address in the list and send another email message to "rv-list-request(at)matronics.com", this time putting the following in the body of the message and no other text: unssubscribe Step 3: In a few hours, repeat Step 1 and verify that your address has been successfully removed. And it says somewhere in the Majordomo manual (way in the back I think...) that this is suppose to work. And it does about 90% of the time. It's not a perfect world and neither is Majordomo... :-) Step 4: "But I did Steps 1 through 3 and I'm still on the List - Get me off!..." Well then, the best last resort before kicking a dent in your new rudder is to just send me an email message directly at "dralle(at)matronics.com" (not to the List) and I can remove your address by hand. And that's just what I've done for you. Best Regards, Matt Dralle RV and Zenith List Admin. PS - I've also added a paraphrased version of this message to the RV and Zenith FAQ for future reference.

Also, pull it longer than your spacing and compress it back to your needed rivet spacing as it is more accurate if compressed to the measurement than pulled out to the measurement.

Subject: converting to C/S prop
I'm converting an IO-320 engine to use a C/S prop. In order to do this, the large plug in the end of the crankshaft has to be removed, and the smaller plug inside of the crankshaft has to be replaced because it has been punctured in order to use a fixed pitch prop. Question, what is the best way of removing the plugs? Does anyone on the list have any experience on doing this? I've already purchased the small plug that will go inside of the crankshaft, and I have a copy of the Lycoming service manual for my engine. However, all it says is to "remove plugs". It's not very specific about how to do this. Also, it calls out a tool to use for seating the small plug. Is there an alternate tool that I can manufacture to do this?

Subject: Re: Oil Separator Return Line
For those of you who have installed oil breather separator units, I have a Q. Have you plumbed the return line (not the overboard vent which goes onto the exhaust pipe) in accordance with Tony Bingelis' suggestion; that is pipe tap the dipstick tube and install the hose fitting there? Or where else? A local Lancair builder incorrectly plumbed the return line to the 3/8" FNPT port or the lower accessory (governor) housing on his O-360 and blew the oil from the case filling up the separator, so that can't be right. Is tapping the current plastic dipstick tube (appears to be .187" wall thk) acceptable (1/4" FNPT) or should I endeavor to get one of the older aluminum tubes? I am open to other suggestions that work well. Thx a bunch, Gary VanRemortel vanremog(at)aol.com ________________________________________________________________________________

And, there have been plenty of little ads and offers and even a few very big ads (such as completed RVs for sale). In the end, we really do want and need some form of advertising on the list.

Subject: Alternator On/Off Switch
Following the recent thread about alternators with interest and I have some pre-conceived ideas about alternator switching, those of you with more knowledge may be able to set me straight. It has been my understanding that automotive alternators are inoperative (switched off) when the ignition key is in the "start" position. I read somewhere that this is to keep the little alternator from getting a hernia trying to bring the system voltage back up to 14 plus when the engine is cranking. It is also my understanding that when the automobile engine is stopped and you want to listen to the radio you use the accessory position of the ignition switch. This position does not send power to the alternator field. Again, we don't want the alternator field circuit telling the alternator "get busy and get that voltage up". The same scenario happens on shutdown, automobile key off, engine ignition and alternator field power go off together - on our aircraft mixture is pulled out and the engine stops, and until the master switch is turned off alternator field circuit screams at the alternator to "get that damm voltage back up!" Another reason for some form of alternator control, be it switch, circuit breaker or whatever, is to reduce the electrical load in the event of a alternator failure. One example - if the alternator drive belt failed you would want to shut off that pesky screeming alternator field circuit because it would be shouting "give me more juice and I will get that voltage back up for you". Anyway it is my understanding that automotive alternators do not get as many hernias as aircraft alternators and actually live longer. In my case alternators may be obsolete by the time I get to my electrical system, however if I do use a alternator I will plan a control switch and automotive type fuses. My alternator will remain off until after engine start and be shut down before the engine is stopped. Now go ahead and make your day, I really need the info.

Subject: Alternator ON/OFF switch
It has been my understanding that automotive alternators are inoperative (switched off) when the ignition key is in the "start" position. I read somewhere that this is to keep the little alternator from getting a hernia trying to bring the system voltage back up to 14 plus when the engine is cranking. It depends on how the ignition switch is wired along with other considerations about the engine systems management functions built into the computers under the hood. Actually, at least from an airplane perspective, it matters not whether the alternator is on or off curing cranking. The thing only uses a couple of amps compared to hundreds of amps by the starter. Further, it puts no unusual stresses on the alternator . . . It is also my understanding that when the automobile engine is stopped and you want to listen to the radio you use the accessory position of the ignition switch. This position does not send power to the alternator field. Again, we don't want the alternator field circuit telling the alternator "get busy and get that voltage up". It isn't just the alternator. Fuel pumps, ignition systems, some cooling fans, etc can run in the IGN ON position that are disabled in the ACC position. The consideration is not one of taking care of the alternator but one of reducing standing loads on the battery to a minimum. The same scenario happens on shutdown, automobile key off, engine ignition and alternator field power go off together - on our aircraft mixture is pulled out and the engine stops, and until the master switch is turned off alternator field circuit screams at the alternator to "get that damm voltage back up!" No big deal . . . the field current rises to it's max value of about 2 amps. If allowed to stay in this condition for too long (no cooling air) you can overheat the field winding but we're talking about tens of minutes before things get really hot. Another reason for some form of alternator control, be it switch, circuit breaker or whatever, is to reduce the electrical load in the event of a alternator failure. One example - if the alternator drive belt failed you would want to shut off that pesky screeming alternator field circuit because it would be shouting "give me more juice and I will get that voltage back up for you". Same, same . . . with broken belt (no cooling air) why waste a limited resource (battery) on keeping an alternator warm? In case of a passive failure of this type, you need to reduce loads on battery to a minimum. In my designs this included shuting off the battery contactor. That critter draws about an amp all by itself . . . if we're willing to shut down an alternator to save a 2 amp draw, how can we tolerate the battery contactor with a 1 amp draw? Both loads represent wasted energy that once dumped into the atmostphere as heat, cannot be tapped to run a radio. Anyway it is my understanding that automotive alternators do not get as many hernias as aircraft alternators and actually live longer. First of all . . . there's no such thing as an "aircraft" alternator . . . at least on the airplanes you and I can afford to fly. Virtually all the alternators flying on single engine airplanes are slightly (if at all) modified version of an automotive design. The problem is that "aircraft" alternators as we know them are based on designs certified back in the 60's and 70's. One of my consulting customers takes brand new Nipon-Dienso alternators and opens them up to remove built in regulators, machine the brush holders to allow direct grounding of one brush, ballances the rotors to VERY tight specs and re-assembles them with the other brush holder brought out for connection to an adjustable regulator with ov protection. In about 7 years of selling these products in a 40 and 60 amp version, fewer than a dozen of over 1000 have been returned for repairs . . . due to owners washing the grease out of the bearings while they were cleaning their engines! I've gathered enough flight test information from flying these products on experimental ships that getting STC's for certified installations should be a no-strain task. In my case alternators may be obsolete by the time I get to my electrical system, however if I do use a alternator What else would you use??? I will plan a control switch and automotive type fuses. No problem >>> EXCEPT <<<< you want to avoid designing a system where the alternator can be left on after the battery is off . . . most alternator/regulator combinations do no run well with a battery off line. This is why I bring alternator and battery on and off together with a single switch. Since I use crowbar ov protection, I use ONE push-pull breaker as the TRIPPED device for the crowbar ov module. This breaker can then become the device for shutting down the alternator during maintenance when you want the ACCessory position on your switches. My alternator will remain off until after engine start and be shut down before the engine is stopped. It'sa no biga deal . . . Since I control with a single switch, my alternators are ON during cranking . . . and I don't care when the master is turned off . . . . you can turn it on and off in flight . . . it shouldn't be a consideration for sequence during shutdown. There's a lot of ol' mechanic's tales wandering around out there looking for good minds to polute. Every time I've asked a proponent of any particular method to explain why it's used, the answer invariably is, "that's what I was taught to do." One never knows who taught the teacher . . . Now, go ahead and make your day . . . . I think you read it wrong . . . to make my day you need to show ME where I'm wrong. If I propose to be a source for good information, I'd better be able to stand against the wall and defend it. If it cannot be defended, it needs to be removed from the playlist. . . . I like to turn off my alternator once and awhile (field) just to see what my battery is putting out (amps) and to see what voltage it will sustain for a minute or so. This kind of a test is pretty meaningless because it's duration is so short. There are two battery considerations. CAPACITY (ability to run minimum goodies for duration of fuel on board - 4 hrs is ideal) and INTERNAL IMPEDANCE (ability to crank engine). These two attributes were pretty well linked to each other in the good ol' flooded battery days but the newer RG batteries can be way down in capacity and still crank an engine. It's interesting that we overhaul engines when compression gets too low, replace belts and tires when they are too worn but we run a battery until it's dead, Dead, DEAD . . . If you really want a battery to be your most reliable source of energy, you need to CAPACITY check it. On a nice, long, day-VFR flight, turn of battery master, close alternate feed to essential bus and start you watch. Whe battery voltage drops to 11.0 volts, see how long it ran carrying just your essential loads (which, by-the-way, should be less than 4 amps . . 3 is better). If it didn't run for 4 hours . . . then consider replacing the battery. IMHO a circuit breaker or fusable link is need in the alternator output lead to protect the rest of your electronics from the alternator in case of voltage regulation failure. No breaker or fuse can be depended upon to protect a system from a runaway alternator. Alternators are by their physical limits, unable to put out more current than they are rated for. (Exceptions are when they're really cold where a 60 amp machine might put out 65-70 amps until it warms up). So, let's assume the regulator is blown and the alternator is full fielded. It goes into immediate current limit at what ever it was designed for which will be LESS THAN the trip value of any breaker or fuse in it's output lead. Now, all your airplane NEEDS is perhaps 10 amps out of the 60. Guess where the rest goes? The battery will try very hard to suck it all in but eventually it looses the battle and bus voltage climbs. If the battery is soggy, runaway alternators can product voltages of 50-100 volts on the bus . . . and never trip the b-lead breaker. This is why GOOD ov protection in the field circuit is essential.

They said the senders were discontinued, no longer available. What good are gauges without senders??? At least they did take them back. Of course, I had to pay the UPS charges to send them back. Am I unhappy with ASS?? You bet your bippy I am. I'd pay twice as much anywhere else rather than order from ASS. The only good thing they have is the catalog. Shop locally whenever you can and if you have to order call Wicks first. Even if it isn't in the catalog maybe they have it anyway.

As the air enters the inlet, the diverging walls will cause the velocity of the air to go down and the pressure up, similar to why a NACA scoop works.

When the product turns out to be defective and the supplier fails to credit my account I simply send a letter to the mastercard bank telling them that the product was defective (or returned, or whatever) and that I'm refusing to pay. I've won every fight of this sort that has come up. The AOPA mastercard agreement gives me 60 days to dispute a charge, and it doubles the manufacturers warranty on most items. That's pretty good protection, and it's free (assuming I pay the bill right away). Yeah, it adds a couple of percent to the vendor's cost of doing business. I've been burnt enough times that I don't care about a 2% hit to the vendor. I'm interested in protecting myself from the sort of $50 rip off that ACS inflicted on John. The only exception I've recently made to my "credit card only" policy was the pitot tube mounting bracket that I bought from Warren Gretz. I sent him a check in the mail, and the pitot tube bracket showed up in about 1 week (pretty fast service IMHO). Oh, by the way, I ordered a pitot tube from ACS two weeks ago. At the time they told me it was in stock. Today they told me they'd have it in a couple of weeks. Hmmm, where'd I put the phone number for Wicks....

Ed Bundy ebundy2620(at)aol.com Ed, From the inlet of the scoop you'll be fiberglassing a tunnel to mate up with the FAB airbox. The distance between the tunnel you make and the FAB airbox should be around 1/4". The tunnel length will vary according to carb location and the diameter of the tube may very well increase over this length. BTW, I made my inlet on the cowl scoop a little larger than received from Van's. When doing the fiberglass work, I'd put some tape over the carb inlet so you don't get FG dust up your carb. One suggestion you might consider that will ease lower cowl installation is to do the rubber seal on the FAB box a little differently. I put the rubber seal on the top of the FAB airbox (horizontally). For the curved portion, I attached the rubber seal to the "tunnel" that is part of the cowl. When you put the lower cowl on, the FAB box nests into the rubber "U" on the cowl. This beats the dickens out of trying to route flaps of rubber through a 1/4" crack. Also, I made removable horizontal baffle seals to help ease cowl installation and removal.

Then laying fiberglass cloth onto the foam and blowing up a balloon into the opening to form a smooth finish with minimal sanding.

Regarding having a backup for GPS under IFR: What's wrong with having two GPS recievers? That way you have YOUR equipment backed up. Of course if the whole GPS sattelite network decides to go down for some reason then you'd be SOL, but that seems kind of unlikely. As for coverage -- if the FAA is really committed to obsoleting VORS with GPS, then there will HAVE to be enough satellites, or the whole system will break down. I imagine that before very many VORs are decomissioned, they will make sure this issue is worked out. I am not just thinking hypothetically here, I am trying to plan for an IFR panel in my RV that won't be obsolete in 10 years, and it seems to me an IFR GPS with a VFR handheld for backup will make a good, minimum IFR panel. This may mean I can't make precision approaches at places where they still require a localizer/glide slope receiver, but I'm not really all that anxious to get into situations requiring hard IFR to minimums in my RV anyhow.

TIME OF COMPLIANCE: Before further flight of the aircraft. Textron Lycoming has determined that a number of high pressure fuel pumps, P/N LW-15473, manufactures between June and October of 1995 may have manufacturing defects that may result in engine stoppage. Several instances have occured where the retaining washer gasket has become separated from the pull rod assembly and lodged in the pump outlet valve restricting fuel flow.

My trusty Lycoming parts catalog states both the low compression E2A and the high compression D2A (actually all the B and D series) use the LW-12416 nitrided cylinder and head assembly. Sounds ok to me to simply replace the pistons. Your E2D uses a LW-12417 plain cylinder; maybe the plain cylinder was tapered but somehow I doubt it.

Subject: Crotch Strap Retro-Fit
A few weeks ago I unwittingly passed on some bogus info to the list from AM-Safe on the issue of adding the crotch strap to the standard Van's issue 503086-405-2855 harness. Don Grego @ AM-Safe had thought that they had a buckle tongue that was approximately .250" longer than the standard in order to accommodate the additional thickness of the crotch strap bracket. This turns out to be incorrect and Don has confirmed that AM-Safe has no buckle tongue with the friction bar adjuster that can accommodate the combined thickness of the shoulder belt and crotch strap brackets. The longer tongues which are available from AM-Safe do not have the friction bar adjuster feature and require that the adjustment feature be designed into the strap (not at the tongue). This feature is designed into the 4000# rated 5-point systems they sell. For the 1500# rated system that Van's sells, the only option for those of us adding crotch straps is to modify the existing tongue. This is easily accomplished and will reduce the strength of the tongue by approximately 25% (from its rated 4000#). The following procedure will guide you step-by-step: 1. Remove the tongue side strap from the aircraft. 2. Using a .058" dia drill blank or pin gauge in an arbor press gently drive the spring pin from the friction adjuster (that knurled bar in the tongue that the strap snakes around). Just drive the pin far enough that you can get it beyond the edge of the tongue. 3. Remove the bar, the strap, the clip and the leaf spring (noting their proper orientations. 4. Clamp the tongue (marked 500535) in a padded vice with the small (mating) end up. 5. Using a .250" dia round file, reduce the shoulder from the stock 1.325" dimension to 1.175" (2 places). Maintain the original tongue width (no more) all the way to the new shoulders, then dress the shoulder areas flat and round the new corners to match the existing radii. 6. Grind the open ends of the stainless steel clip (marked 500535-401) from the stock .425" dimension to .350". Round new corners to approximately their original radii. 7. Complete the assembly in reverse order of disassembly and drive the spring pin home using an arbor press or channel lock pliers. Done! You are on your own to engineer the crotch strap anchor point in the seat area but it needs to be in the rear of the stick cutout area. It really doesn't have to be that strong as the crotch strap merely reduces the tendency toward performing the humanoid harness limbo and helps keep the lap belt low and comfortable on the hips When donning your new five point harness, install the crotch strap bracket on the tongue first then the shoulder strap brackets, then buckle. The twisted geometry of the crotch strap bracket will nest better against the relieved tongue shoulder than against the shoulder strap bracket. Any other Qs, E-mail direct.

Subject: Re: How do I lift an RV6A with engine for wing and landi
Hello All.... Just my $.02 on this subject - maybe it'll help someone... The fuselage will probably be on the gear using the wooden "dummy spar" for a long time while you are getting the fiddley stuff done, - fairings etc ..etc...and also while you move to the airport for wing attachment & final assembly. - O.K. - This is what Greg Bordelon and I did on mine..... The actual move was "painless" actually... after toying with the Idea of using extended trailers or similar, we opted to call the local wrecker company to do the deed. They arrived with the specified big "flatbed" type of truck,.. you know.., the ones' where the bed slides off the back, then winches back on. He charged 75.00 for the move (about 8 miles and 45 minutes T.T.) and it was worth every dime. Amazingly enough, he said that it was not his first plane move!! The wings travelled along with us - in their cradle in the bed of a pickup truck. As for the big day when it is time to put the wings on - not too tough really. We used a couple of 2x8 planks about 8 ft long, resting on 4 saw horses. The saw horses should be about the same height or just a little taller than the bottom of the fuse. Position the first horse next to and parallel to the fuse and put one end of the plank on it. The plank is now placed under the firewall bulkhead, and covered with blankets/ pillows to cushion your vulnerable bottom (oops). Remember, it is 8" wide so the load is well distributed also. Take a deep breath, Cinch up your Jockstrap, and lift the other end of the plank - and up comes your bird - WOW! - wheels up for the first but not last time - and slip another horse under the second end. The plank will bend a bit - but don't be alarmed! Repeat using another plank and 2 horses at the tail to get level flight condition (longeron horizontal at the cabin rail) so that you can align the incidence angle accurately - as per the manual. FYI - We found that final wing attach - installing all those the spar bolts to be a real bitch...( unless of course you are deformed - double jointed and with strong 5' arms, with 2 elbows per arm would be about right I think). Well, mainly Due to excessive beer sampling duties in a previous existance - my own large, 2X, manly frame simply would not bend to the alkward angles needed to lovingly, gently, and tenderly beat the requisite amount of **** out of those bolts. So I somehow got Greg to do it -- (Thanks again Greg!!). Took about 3 Days and a lot of messing about with the legs to get final bolt alignment, and many bad words. (mostly directed at me by Greg). Anyways up, I went on for longer than I wanted to - but what the hell. The above worked well for us - and even with the bird painted we didn't mess up the cosmetics one bit.

Subject: Re: Future of Aviation Navigation
I've been assuming they'd retain the VOR transmitters for those rare cases where you just happen to have inadequate satellite coverage. You need a back-up system. ====================================== The system is composed of 24 satellites and 3 spares. In concept they will bring down the old sats and launch new ones as future technology improves. The orbits are inclined in 6 planes around the earth. In the air my GPS almost always locks onto 6 satellites and only rarely has it been 5. The Russian GLONOSS system is said to be more precise because they do not have SA(selective availability). SA is the US military requirement to degrade the signal (i.e., positional accuracy). However, the military has announced they will turn off SA by 2010. With WAAS (mentioned earlier on this list) and Deferential GPS, the use of SA becomes irrelevant for general and commercial aviation. Each satellite has its own atomic clock and each clock is updated every day. There is already redundancy built into the system. I don't know the odds but I feel much more secure that a satellite will be waiting for me 200 miles down the road than when I am tuning in the next VOR and listening for that dit dit da. In the future you will most likely see a system that integrates both the Russian and US systems. Aschroft now sells a expensive GPS that will lock onto BOTH systems. How do you say "back-up" in Russian? Ground based nav-aids are old technology, frequently broken, and expensive to maintain. Just think - there are more than 400 VORs in the US alone and now 24 satellites are giving you world wide coverage. I was surprised to hear that a part of Australia lacks occasional coverage. I would like to learn more about that. Elon ormsby1(at)popsicle.llnl.gov ________________________________________________________________________________

I had already had my cly. checked etc, the guy asked do you want to make this a 160 hp? I asked what it entailed and he said different pistons and wrist pins (piston pins). I asked if the wrist pins were different wouldn't that mean different connecting rods, he said no, the connecting rods were thicker walled but the same diameter. There was nothing about redoing the cly, just ordering different pistons, and since we had not yet ordered the pistons, he said the price would be the same. Since I'm an old hand at rebuilding cars to 'original'. I elected to keep my engine 'original' Hope this helps some.

It would seem that you can't back rivet if you put the leading edge skin in the jig cradle for riveting. I would assume that you leave the skin attached to the ribs on the main spar when back riveting. Is this so? Do you usually back rivet the top leading edge skin and remove the skin and put in the jig cradle to finish riveting the bottom of the leading edge skin with a bucking bar. My thinking of this process may be a mess. Would appreciate someone straighting me out.

This choke occurs in the last 2 inches of travel. This area expands in operation because of the heat generated in this area. If the bore were not "choked", the piston/rings would slop around at the top of the stroke. This causes wear in the top compression ring and it's groove. My information source for the above is: the "Sky Ranch Engineering Manual" by John Schwaner, a book I highly recommend, by the way.

You might consider this instead of stainless tape. My roll of stainless is still on the shelf. The tape Mark is referring to is .010" thick and comes in widths of 1/4" to 5" (up to 17" widths can be ordered) and the roll is 54 feet long. The 3" x 54' roll is $ 39.15. This will do a lot of flaps. I also put a 3/4" strip of this under the wing skin where it contacts the flap. Whether you use stainless or the UHMW on your flaps, they will eventually scratch unless you were to wipe the flap and bottom of the wing skin each time before you retract your flaps which is pretty impractical. Scratches in the UHMW aren't very noticable whereas they are very noticable with the stainless steel tape. BTW, I installed the tape on the flap after it's final coat of paint and after 300 hours, it's still stuck good. The adhesive on this tape is really sticky. I've found a lot of other uses for the UHMW tape. It can be used anywhere things rub together. Landing gear fairings and top and bottom cuffs, wing root fairings, on the tip-up canopy side skins where they over lap the fuselage. I'd guess this material would work well on the aft deck of the RV-4 where the canopy rubs the fuselage. I've used it on the engine mount where there is a possibility of something rubbing the paint off the mount. I used a couple of small pieces on my six where the rudder cables exit the fuselage. It's handy for stuff around the house, too. I put some on my Nordic Track skis when the little "bumpers" wore off. That was two or three years ago and it hasn't worn through yet. For anyone interested, the name of the company is United Plastics Corp. and they can be reached at 1-800-537-9724. Get their catalog, they've got a lot of other interesting stuff in there, too.

They still haven't been manufactured yet!!! The three cables will have a threaded steel sleeve swaged on the casing where it penetrates the firewall. The following cables were ordered for my RV-6A with an O-320 D1A engine and Woodward governor. They will be installed horizontally under the instrument panel. I will not be using the vertical arrangement as specified in the plans. Throttle cable: A-800 Black friction lock control (ACS#05-08648), 48" long with a threaded steel sleeve located 24.0" behind the panel nut. The cable will penetrate the firewall through the slanted surface of the governor box, on the right side. Mixture cable: A-750 Red Vernier control (ACS#05-07848), 48" long with a threaded steel sleeve located 24.5" behind the panel nut. The cable will parallel the throttle cable. Prop Cable: A-750 Blue Vernier control (ACS#05-07960), 60" long with a threaded steel sleeve located 32.5" behind the panel nut. The cable will penetrate the top left side of the firewall. The controls are still on order, so I haven't actually installed the cables with the above dimensions yet. If a dimension is in error, I will post it to the list. ACS quotes a price of $6 for the threaded steel sleeve. The cables were ordered along with many other items. They billed me for the shipping on the in-stock items that were shipped. I was billed an additional $15 for shipping of the cables. This policy was NEVER explained either in their catalog or when the order was placed. The $6 sleeves wound up costing $11 each when the additional shipping is added. The $15 shipping charge that was billed to my credit card is in excess of the rates published in their catalog. For the shipping to be $15, the cables would have to weight a total of 27 pounds!!!!!! IMHO, this borders on credit fraud. They have already charged my credit card, the bill has arrive from Mastercard and I have to pay for them or face finance charges, even though THEY HAVEN'T BEEN MADE YET. Wicks has the same cables, without the sleeves, in-stock with the exception of the throttle cable, which is on back order. If ACS had been up front with me from the start, I would have ordered stock cables and put a grommet with shield at the firewall penetration. If I had known then what I know now, the stock cables would have been ordered from Wicks. Hopefully others on this list will keep this in mind when ordering their MTP cables. ACS isn't the only supplier out there. -Scott Gesele N506RV scottg(at)villagenet.com ________________________________________________________________________________

Couldn't pass this up . . . . in my experience, too many builders put off consideration of electrical system issues until the airplane is about done and they're ready to start stringing wires. I'd encourage every builder to start gathering information early . . . the range of options is tremendous. I'd like to believe that when the time comes to start stringing wires and drilling holes in the panel, you've had it all planned out for some time. Whether the 'Connection is involved in your project or not, try to develop an awareness and appreciation for things that are hidden by sheet metal, paint and upholstery. If you see an airplane done by a real craftsman, ask if they documented their electrical system and the materials used. Quite often they're willing to share it. You're not necessarily looking for a system to clone . . . but you'll be surprised how easy it is to make decisions about your own airplane after you've researched a dozen others. If you're an AutoCAD user, I have uploaded a wire book "seedling" disk to the maintenance library of AVSIG on Compuserve. The same data will be downloadable from our website in a few days . . . I'll post a notice when it goes up. This disk contains a wire book in process for a client's airplane. It has the forms, symbols library and lots of systems pages already drawn . . it can save you HOURS of work. Search on "nuckolls". Bob . . .

I've never heard of anyone trying to backrivet the LE. However, it sure would be neat if someone would try it and report back to us:) I speculated on the list some time ago about doing this and when I get to that point on my wing construction, I'll check it out for myself. I thought it might be possible to leave the LE clecoed to the front spar and all of the ribs and, starting at the bottom of the ribs, start back riveting and work toward the nose as far as you can go. The idea didn't seem to generate much discussion on the list and it may not be worht the risk to a lot of builders. They do make a right angle rivet gun, which is quite expensive. Also, there is a very short barreled, straight rivet gun that uses a special, short rivet set that looks as though it might fit inside the LE and tank while it is off the airplane and in the craddle. It's priced at $ 320.00 from U.S. Industrial Tool & Supply. On the main skins, back riveting seems to work very well. I didn't do this on my first RV but bought the back riveting stuff for my second. I helped a RV-6 builder in CO back rivet his wings and it worked out well and I sure intend to do my main skins on my second RV. There are also a lot of places on the fuselage that back riveting will work. Bob Skinner RV-6 BSkinner(at)krvn.com ________________________________________________________________________________

Subject: Re: Future of Aviation Navigation
Elon, I should have posted to the whole list, I provided some info on this to someone else. The GPS satellite system is biased towards the continental U.S. and the Northern hemisphere. As you built the system we cannot really complain. For this reason the orbital planes are established to provide optimum coverage for the U.S and Northern hemisphere. There are occasional periods in the southern hemisphere when there are insufficient satellites in view for a GPS to maintain its RAIM function. This does not effect GPS as an aid to VFR navigation but does effect its licensing in Australia for sole IFR use. There is much discussion by our local aviation authority as to means of providing sufficient systems integrity to enable GPS to be used as a sole IFR aid for en-route navigation and non-precision and precision approaches. For us even one satellite is a big ask although one geo stationary satellite over Australia would provide the requisite wide area augmentation.

If the tab span does not exceed 35% of the span of the supporting control surface, the total free play shall not exceed 2% of the distance from the tab hing line to the trailing edge of the tab perpendicular to the tab hinge line. If the tab span equals or exceeds 35% of the span of the supporting surface, the total free play is not to exceed 1% of the distance from the tab hinge line to the trailing edge of the tab ...

Subject: Cylinder Choke...Explanation
For Elon...and others.... >From Light Plane Maintenance's Book, TOP END, Chapter 2: "...In aircraft, choke is the difference between normal TBO and a premature top overhaul. In an aircraft-engine cylinder, when the crankcase end points up, the clyinder wall taper toward the "head" end of the barrel. This taper is the cylinder"s "choke". Why taper a barrel this way? In an air-cooled engine, a fairly extreme temperature gradient exists from the base of the cylinder to the head during normal operation. Thus, if the cylinder barrel did not incorporate a slight taper when cold, it would assume a negative taper or "tulip out" when hot due to thermal expansion at the combustion end. This, in turn, woiuld lead to irregular, rapid ring wear, poor oil control, and loss of combustion efficiency. This why a new Lycoming and Continental cylinders leave the factory with as much as .010-inch taper at the head end of the barrel. It doesn't take much choke to do the job......... Lycoming's direct drive Table of limits doesn't contain new-limits choke specs, but does set a service limit of .0045-in (for-and-a-half thou) on old barrels. ......" My old 1969 Lycoming 320 in my Cessna 172 has about 5900 hours since new, has been overhauled twice, has 1900 hours since last overhaul, and on my trip to from So. Cal to Alaska and back this summer, used 5 qts of oil in 55 tach hours (11 hours/qt). Whoever last overhauled it....got the choke right! ________________________________________________________________________________

Subject: Main skin overlap.
A few weeks ago I looked over an RV6A that was an excellent example of workmanship. I noticed that the builder had used a unique approach where the inboard & outboard top skins overlap. I wonder how unique this is. The technique: Where the top main skins overlap, the outboard is on top of the inboard skin. This causes a small uneven area, due to the thickness of the metal. This builder trimmed back the area that was sitting over the spars from the inboard skin. This let the the outboard skin lay flat against the spar over the inboard skin, the un-trimmed part. Now before I confuse you more, there is a double set of rivets in the area where the skins meet. One row runs down a rib the other just goes through the two skins. He did not trim this area, just the area over the main spar and rear spar. This allowed the skin to lay flatter and be less notable. Here is a cryptic diagram in an attempt to clarify the above description. -------------| main spar |----------------------- -----| |. . Z Inboard . .| |. . Outboard Z Top . .| |. . Top Z Main . .| |. . Main Z Skin . .| |. . Skin Z . .| |. . Z . .| |. . Z . .| |. . Z -----| |. . Z -------------| rear spar |----------------------- ^ |- Inboard and outboard skins meet here. Now if you slide these together, with the outboard over the inboard skin you will see what I mean. He did not do this to the bottom skins, no one pays them any attention anyway. Even with a relief cut/hole in the corners of the cut out areas, it looks like a good place for a crack to start. IMHO Just how unique is this? Have any of you seen or done this to your skins?

I've heard that the pegging of the "G" meter may not be all that significant. The centrifugal force imparted to the fuselage when the wing seperated could have easily caused the meter to peg and freeze.

Louise, Deju vu for me! It took 4 or 5 times welding in different places before those d### exhaust pipes didn't crack anymore. The final fix for me (800+hrs,no cracks) were two braces from eng to pipes and a crossover brace pipe to pipe just to the rear of where the eng to pipes braces would be.

I had bought a Tolle system but after hearing of all of the problems, sold it at a loss and bought a Vetterman 4 pipe system made of mild steel. I just didn't want to take a risk of catching something on fire with the Tolle system. I bought the four pipe mild steel as it was the cheapest and I figured I'd already tied up enough money in exhaust systes. The homebuilt bulletin board in K.C. is full of problems with the Tolle system. Alan is a nice guy but his systems stink. Some of the fixes tried include gussets, slip joints and saddle links (like Vetterman uses). Also, the interior of the tube must be flooded with argon. (This is a tidbit stuck in the cobwebs of my mind, don't remember who told this to me.) The main problem area of the Tolle system in on cylinder #4. I now have the Vetterman stainless steel crossover. The reason for the change from 4 pipe to crossover was to obtain more cabin heat. So far, I've not heard any complaints about the Vetterman system. By the way, I still have the Vetterman 4 pipe and will sell it for $ 150.00. Bob Skinner RV-6 BSkinner(at)krvn.com ________________________________________________________________________________

A box of scotchbrite pads Don't buy scotchbrite pads from tool or paint suppliers. You can use the regular green dishwashing ones from your local supermarket... heaps cheaper. I originally bought one each of the red and grey (coarse and fine) pads, but have only occasionally used the coarse one, and never used the fine one I buy my scotchbrite pads from local industrial tool suppliers. I buy only the red ones and scuff the whole plane with these prior to painting. They are not very coarse, ie. no deep scratches (the green ones just piss me off). Additionally, I purchase them by the box or case.....what ever it's call. After using them for a while you will be able to tell when the one your using is worn and needs replacing.

When attaching stainless steel tape to Flap leading edge should the flap be painted with primer first or is it ok to attach to unpainted surface? Also is is best to leave top surface unpainted or has anyone painted it along with rest of aircraft? Don Pfeiffer RV6 donp(at)scruznet.com ========================= Don, On my friends (Rob Lee) plane we painted the top side. The steel tape is in place and seems to work fine once you get it on right. "Check Six Mark" has a supplier of a semi-clear plastic tape that looks real nice. I'm planning to us the semi-clear tape on my plane but I don't understand why we can't apply the tape to the underside of the top wing skin.

Subject: Oil Separator Return Line/Ugly Goop
Date: Sep 13, 1996
Why would you want to return that ugly goop to the crankcase? Some builders have been collecting the oil return in a f-wall mounted container and periodically draining it. This will keep the stuff off the belly of the plane. The cowls come off at oil changes. Does anybody have a feel for what volume is required (25 hour intervals). David Fried dfried(at)dehavilland.ca ===================== David, The volume of oil in the seperator is unique for each engine. Engine blow-by is a good indicator of the overall health of the top-end. This is a case where less is best. Every engine will have some blow-by. What is normal volume? I don't know and it depends on how much money you want to spend in the top-end. Most a/c I've seen seem to have a one to two pint can mounted to the firewall. Maybe other listers can inform us concerning how much oil they are trapping. For example: my Cessna used to have a oil slick on the belly continuously, I replaced the pistons/rings and cylinders and now I have a clean belly.......a/c belly that is .

This aircraft, if the >meter >is to be believed, was pulled beyond the ultimate design load. > G meter readings in an aircraft that has hit the ground after an in flight break up mean little to me. What do you think the G meter did when it hit the ground? Unless something pinned the meter in flight as the aircraft broke up it's readout could be altered when the wreckage impacted the ground and thus rendering the data useless. I would think more reliable information can be obtained by the observations of those that saw the incident. The deails in the NTSB accident synopsis were "The pilot of the RV-3 initiated a steeply banked right turn, after following another aircraft in a rapid climbing maneuver. During this turn, which was described by witnesses on the ground as extremely tight, the right wing was seen to separate from the fuselage." So who knows what the G load really was. Unfortunately it took this accident to uncover the potential problems with the 3 wing. Van has taken the necessary steps to insure the 3's are modified to withstand his original design limits. The wing is different from the 4 & 6 wing and those have been tested. Regards: Rusty Gossard N47RG RV-4 Flying 2 Years ________________________________________________________________________________

Subject: canopy frame details
Okay, guys and gals, a question I need answered ASAP, if you please: I'm at the point of cutting the plexi for my 6A tip-up canopy (gasp, tremble, swallow hard). Before I do, I want to get (at least) one thing straight. The canopy must transition from sitting atop (outside, if you will) the fwd canopy skin to a position inside(below) this same skin as it wraps around the sides of the canopy frame. (i.e., the plexi must cross the plane of the aluminum skin at some point in order to fit in the groove on the side pieces of the frame, since the aluminum skin becomes the outside of that groove at the sides, yet sits below and inside the plexi up front over the instrument panel). Is that clear as mud?? Those of you who have completed this phase will know what I mean. As I see it, one of 3 things must happen: the skin must be notched or the canopy must be notched where the two pcs cross over, or the skin must be dog-eared inward at the corner to lie flush with the canopy frame side pcs and let the plexi pass over at that spot. Any of the above would then need to be concealed with the figerglass fairing strip. My detasiled study of the latest update of the manual and plans has shed no light on this geometry. The photos are of the prototype parts which only vaguely resemble the parts before me. Vintage Van's documentation, for sure. Boy, if they had *me* to do their manuals, I'd make sure they were thorough and we could *all* understand everything . Well, they haven't offered me the job, so that's everyone's loss, and Frank Justice will just have to fill in for me :-) Any suggestions on how to fit the canopy and skin happily together would be appreciated. I hope to forge ahead with the Norton wheel tonight! Bill Boyd SportAV8R(at)aol.com ________________________________________________________________________________

After attaching my rudder pedal cables to the pedals and testing them through their range of motion which is governed by the 35 degree rudder travel I found that the front attachment (F6121) of my rudder cables "bump" the plastic grommet in my F602 bulkhead. My first thought was to wrap a piece of small dia. plastic tubing around the cable and the attachment so it travels smoothly over the grommet in F-602. any other suggestions would be welcome. chet razer: crazer(at)egyptian.net ________________________________________________________________________________

Hi, This recent discussion about the air-oil separators has got me wondering. It hadn't occured to me to put on in my 6A. Now I'm thinking - should I?

I would have to say that the G meter being stuck at 9.2 g's would have to mean that a 9.2g force from either acceleration or deceleration would have to be exerted on the meter until the meter was catastrophically impacted in such a way that the device locked in that exact indicated position. IMHO I would have to say that a 9.2g force created from a control input would not "lock" the meter in that precise position. In addition, I don't believe that the forces generated by a nasty in-flight break-up would lock this guy in position either. I would say that the forces required for such a thing to happen would be much more likely to occur from the rapid deceleration of the device as it impacted the ground or another object of large mass.

Subject: Back Riveting -Wing Skins
I back rivetted the top surface of the leading edge of my left wing and it turned out great - much better than my right wing that I did in the traditional cradle method. I clecoed the top leading edge to the spar to be sure everything was properly aligned, and then removed the clecos from the bottom surface so that I could lift it up to back rivet. After the top was back rivetted, I clecoed the bottom surface back on, removed the leading edge from the spar and finished the rivetting job in the cradle. I used the extra long back riveting set and dumb-bell bucking bar obtained from Bob Avery. I started at the bottom and worked up, rivetting in the same basic sequence as I drilled. The last couple of rivets near the leading edge were a little touchy, but it worked ok. I recall that I left the forward most cleco on the bottom side in place as long as I could to help keep the top skin tight to the ribs. Bucking the bottom of the inboard rib was also a little tight, but my hands were small enough to get it done. Would I do it this way again? You bet, the result is worth it.

I've never heard of anyone trying to backrivet the LE. However, it sure would be neat if someone would try it and report back to us:) I speculated on the list some time ago about doing this and when I get to that point on my wing construction, I'll check it out for myself. I thought it might be possible to leave the LE clecoed to the front spar and all of the ribs and, starting at the bottom of the ribs, start back riveting and work toward the nose as far as you can go. The idea didn't seem to generate much discussion on the list and it may not be worht the risk to a lot of builders. They do make a right angle rivet gun, which is quite expensive. Also, there is a very short barreled, straight rivet gun that uses a special, short rivet set that looks as though it might fit inside the LE and tank while it is off the airplane and in the craddle. It's priced at $ 320.00 from U.S. Industrial Tool & Supply. On the main skins, back riveting seems to work very well. I didn't do this on my first RV but bought the back riveting stuff for my second. I helped a RV-6 builder in CO back rivet his wings and it worked out well and I sure intend to do my main skins on my second RV. There are also a lot of places on the fuselage that back riveting will work. Bob Skinner RV-6 BSkinner(at)krvn.com ________________________________________________________________________________

Subject: 150 hp to 160 hp upgrade
There are two things to consider when modifying the **-320 series engines. I paid $7,840.00 to learn this. My engine was tagged IO320B1A, and I was assured it was. I put 430 hrs on it, on top of 568 sfreman. It started to foul plugs badly on 1 and 3 cyl.s, so I pulled them to have them checked out. By the time the engine was back on the plane, it would suffice to say the "case" was the only thing that was good. IMHO, put out the cash for a new engine; the chances are real good you will end up like me and a lot of others with an equal amount of money in a "bargain" engine. I bought my engine 6 years ago for $5300.00, spent $7840.00 for a MOH this year, and new engines from Van were $14,000.00 at the time. 1) The cylinders for the 160 are tapered. I highly recommend using these cyl.'s when doing a 160 hp. engine. Even in new, tight conditions, I am getting more power than I ever did with the straight cyl.s that were in my engine (which were supposed to be tapered). 2) If you are doing this to an -E series engine,such as an 0320E2D, bear in mind that the front main bearings are the same as the 0-290 engine and are not as strong as the factory 160 hp. engines. The people that did my overhaul, Premier Aircraft Engines in Troutdale, OR ( who are engine gods in my view), and also an author that I forget, do not recommend using 160 hp pistons on these engines because of the higher pressures. And if you are going with a CS prop, there is even more reason. I'm not on the list, so if you have any Q., email to me.

Subject: RV-6 tip-up canopy cutting
Looking back, I guess I was doomed before I picked up the cutoff wheel. I never knew what hit me til it was all over... I was going to be oh, so careful, too. Measure three times and cut once, as they say. But now I can write a sequel to Ken's "Traps in Cowl Land." If you haven't begun the successive-trimming butchering of YOUR canopy yet, let me warn you. Don't make the assumption I did. The beautifully-molded compound curve in the front of the canopy is the scrap; the simple curve in the rear is the part you want to save, and measure your initial trim distances from. Don't ask why, it just is. Maybe they did it to torment you. I can attest to one thing: if the canopy blank is carefully trimmed along the front mold line and then measured back the suggested distance, it will indeed look like a good fit in the making. You cannot tell much at this point, since the canopy must sit atop the fwd fuselage skin in the rear, but ultimately must be trimmed to fit beneath it. Because if the varying top curvature, the canopy will not lay properly atop the rollover structure without much of the front plexi trimmed away (takes forever in small passes) and by the time you do that (or at least by the time I did that)- voila! the rear of the plexi has moved forward as well as upward as the front is nibbled away. Very anguishing to watch this happen and be helpless to stop it. Now your canopy is lined up (no more vertical gap in the back) but the aft edge is sitting 3" in front of the fwd fuselage (turtledeck) skin!!! A permanently open sun roof! How neat! Know what time it is now? Time for a new skin, one you can trim to match the remaining plexi and fashion your new, much smaller rear window! Fear not; Airparts will sell you a suitable 48x72 piece for around 50 bucks, and not only will the service be faster than Van's but the crating charge will not double the cost of the order! Next week I learn to drill off a skin and use it as a template for a new one. The missing plexi I need is in the scrap pile, gone on the initial trimming, and in retrospect looks like it would have fit the turtledeck very well indeed. :-( Why not leave the rear a bit long at first? It will hit the baggage bulkhead in the rear unless trimmed before first fitting; the mistake I made was to assume the front mold flange was the initial starting point. If I had it to do over again, I would trim the rear flange conservatively and make the first big chop in the front, in that beautiful sensuous compound curve that your instincts tell you is to be conserved at all costs- WRONG! Done properly, you will end up cutting much more of the front away than the rear. At least I think this is so. I haven't done a canopy properly yet, so I'm speculating. So, next time I want to lighten the aeroplane and shift the c.g. forward, I think I'll leave off an elevator, instead. ;-) Thanks to all who responded to my earlier canopy querry, but now I've got bigger concerns.

Subject: Re: Exhaust failure #4 cyl.on 0-320D1A-Tolle design
I have a couple of ideas about the failing exhaust systems that I would like to share. It sounds like what is happening is high cycle fatigue if the pipe(s) and the point of failure is the pivot point of the moving mass. A couple of things to keep in mind for a problem like this: The natural frequency of the pipe(s) is probably in the same range as the frequency of the exciting force(eg. engine, prop and other moving objects)or it could be a 2nd, 3rd, 4th, and so on, order harmonic of the exciting force. This will account for why there are varying failure times in relation to the same design on a different airplane, as there are differences in the rpm and engine types and prop types. This means there are a couple of ways to stop this problem as follows. 1) change the mass of the pipe(s) to change it's natural frequency. 2) determine the frequency range and node locations (if harmonics are involved) and brace at the node(s) to reduce the effects of the vibration by dampening and stifening. 3) determine at what rpm the damaging frequency occurs and avoid prolonged running at that setting thereby avoiding exciting the pipe(s). If you want to know what the natural frequency of your exhaust sytem really is it's a matter of placing an accelerometer on the system with the engine off and taking a small deadblow hammer and rapping the pipe. A peak will occur indicating the natural frequency. With that information in hand one can simply do the math to learn about what frequencies could be exciting the system. It's not really as difficult as it sounds and really the people who manufacture these systems should study there design in this way and design for success BEFORE they ever sell the first system. groberts(at)telcomplus.com > > writes: >>I don't think Larry would fit:) I was pretty miffed after I had bought >my >>Tolle system and found out that several "in the know RV people" knew of >the >>big shortcomings of this system and yet, nothing was said.

Subject: Report of incident
I would like to report two items to the list. I have RV-4 kit #3933 which was first flown in April 96 and currently has 85 hrs. 1 - At about 60 hours I had the cowl off doing some minor maintaince. I happened to notice two bends in the firewall, about one inch above the lower engine mount attach points, both on the corners of the firewall, the 90 degree bend in this area is for the rudder peddles to move freely. A friend and I inspected the motor mount, rivets, weldments inside, longerons and could find nothing unusual. I called Van and talked to Tom Green about it. He indicated that this has been reported before on RV-4's with the longer gear legs and that he feels it is some sort of stress relief which is taking place and that the area should be re-inspected during annual. I had the cowl off at 85 hours adding break fluid to the reservoir (sp?)(see below) and the area seems to be the same. I don't believe this was apparent during my 50 hour inspection as I changed the oil at that time and believe I would have noticed it. I don't remember any landing hard enough to be suspecious. I will continue to monitor the areas every time I have the cowl off. 2 - Just after landing 9/15/96 my left break peddle "went to the floor". I was able to safely taxi to the ramp and pulled the wheel pant. Break fluid was dripping on the left wheel. Upon inspection I discovered the AN fitting that attaches the AL break line to the 90deg elbow was finger loose. After re-tightening it the breaks functioned normally. When I got back home I checked the reservoir and found it to be about 3/4 low on fluid, I filled it back up, checked #1 above, replaced the cowl, pulled the other wheel pant and checked the other break (it was ok but I could tighten the fitting about 1/8 turn) and declared the A/C airworthy for the Roswell fly-in next weekend! If anyone has any comments on either incident (good or bad) I will certainly welcome them.

Final indication of the meter is either when the last force is >imposed on the meter (impact with mother earth) or, if the manuever >indication is to be believed, the g meter would have to be catostrophically >locked in place where it could not respond to the impact with the ground. A couple of things here, and maybe we can lay this issue to rest... I've been an accident investigator on two Air Force A-10 accidents. In each case, we were able to ascertain the G forces PRIOR to impact by obtaining "capture marks" on the G meters. As Jerry Springer explained, the needle makes a small but definite mark on the guage on impact with the ground. In the case of the G meter, we could tell the maximum positive and negative Gs the pilots had pulled by those marks. Mr. Roberts is incorrect in his statement that ground impact will cause the final readings on the G meter. The impact marks on the G meter will show the current G as the aircraft hits the ground. The needle is "captured" before it can actually move to show impact forces. An aircraft hitting the ground in a situation as described in the RV-3 accident would most likely impact with more than 9.2 Gs, more likely 30-40 Gs. Bottom line: you don't look at the needles...you look at the marks the needles left in the face of the guage. Another issue. In the A-10 and most, if not all, jet fighters, we have two positive G limits: symmetrical and asymmetrical Gs. Our symmetrical limit is 7.33 positive Gs; asymmetrical limit is 5.0 Gs. A symmetrical G is one where the acceleration is essentially through the top of the aircraft, either straight and level or in a steady-state turn. An asymmetrical G is one where the aircraft is rolling; not necessarily turning, but in the act of rolling. (You aero engineers can probably explain this better.) In the RV-3 situation, where the pilot was in a hard left roll, the right wing was no doubt pulling more Gs than the left. The pilot may not have felt like he was over-pulling, but the aircraft sure felt it! It's interesting we don't hear about symmetrical and asymmetrical Gs in the civilian world (at least I haven't). IMHO, it's important to consider that, while rolling, the G meter might say "9 Gs" but the outside wing is pulling 11 or more. Let's be careful out there!

The aircraft is well built and there have been no "hard" landings. He noticed his firewall problem at about 10 - 15 hours. He now has over 300 hours on his aircraft and the bends have not changed at all. I have not seen this on the other 2 RV-4 in my hangar or any other RV that I've looked at. It seems to be a cosmetic problem (after the stress is releived from the firewall that is). Gary Corde RV-6 N211GC ________________________________________________________________________________

Fellow RVers, Although I only live 110 miles from York, NE, home of Craig Bairs award winning RV-6, until the Sat. Fly-in at Harvard, NE I had never seen the plane. We missed each other by one day at S&F. His six was awarded best low wing at S&F this year and is featured in the Sept. issue of SA. It's a beautiful airplane. The leather interior is really well done (and smells good, too.) You can read all about it in SA. One of the things that he'd done that I thought was pretty clever was mentioned in the article. It's the joggle that he put in the rear of the forward fuselage skin. The forward part of the tip up nests into this joggle almost perfectly and because he used the goose neck hinges, he said he has absolutely no air or water leaks. Of course, this idea would not work if you choose to have the canopy side skins overlap the fuselage. Craig's canopy butts against the fuselage side rails, per plans. I told Craig about the RV fly in at Burlington, CO on Sept. 28th and he said he'd try to get there.

I saw several RV6 fuselages in his shop during the Chino, CA fly-in and they all had the following modification. When he fabricates the F-668 bulkhead (the aft end of the fixed forward top skin), he places a strip of aluminum (about 7/8 wide - 0.025 or 0.032) in between the top flange of the F-688 and upper deck skin. With about a 1/4 inch of this strip exposed after the skin is attached, a nice 'ledge' is formed for the canopy forward skin to close against. This is instead of the canopy forward skin resting on the 3/16 radiused corner of the F-688. It also gets around the 'disappearing' 3/16 radius as you get closer to the longerons (caused by the taper of the forward fuselage -- see the archives). Since the F-688 is spliced from L and R parts, and notched for the longerons, it can be easily adjusted to allow for this extra strip over the F-688. It seemed a really good idea to me, but unfortuneately came to late for incorporation on my fuselage .... :^( .... it would have also saved quite a bit of "fiddle time" and well as looking neater and providing a better air/water seal. ... hope it helps someone else ...

I had asked the same question, and got three equally good responses. The concensus agrees that the plans are deficient in this area and something is needed. 1. Just crease inwards (mash in) the canopy deck where the transition from side to forward deck occurs (the Bob Skinner and John Darby approach). 2. Cut a vertical notch similar to that shown on the plans for the sliding canopy in the same area (the Jim Stugart approach, I think) 3. Cut a slit in the forward canopy deck that is just (about 1/16) below the edge of the plexi. Start the slit at the aft edge of the forward canopy deck, and cut it about 4 inches long. End it in a nice stress relieving hole. At the aft end, just above the slit, pull in the aluminum and rivet it with a flush rivet to the canopy side rail. The blending you need will now occur smoothly along this 4 inches from the canopy side rail to the end of the slit.

A heavenly scene in the far distant future: Van went to Heaven upon his death and was given a warm welcome at the Pearly Gates. St. Peter, after completing the formalities, asked him how he would like to spend his time. Van, the great inventor, asked to see some of the inventors before him. So St. Peter printed out the list of all the inventors currently (doing time) in heaven. As Van started to go through the list, he came across the name Adam. He queried if it was the same guy who discovered Eve, the woman. St. Peter confirmed that indeed Adam was the man credited with the invention of women. Van requested an audience with Adam, as he had a few things to straighten out with him. When the scheduled meeting took place, Van was all over Adam, attacking him for the flaws in his invention. "Your invention is the most stupid work of engineering I ever saw. There is too much of front end protrusion, the rear end wobbles too much, it chatters at high speeds and the intake is placed too close to the exhaust." Obviously, Adam doesn't like it too much. He thinks for a while and then leads Van to the Celestial Computer. He works with the enormous data-banks and in a few minutes there are beeps and all that, and out come a few charts and graphs. "Look here, Van. Despite all the flaws you pointed out, data shows that there are more men riding my product than yours."

I have no explanation, except that where the gear legs tie into the center floor ribs might have been a bit out of whack, previous to the aircraft adjusting itself. Do to this being a possibility, I'm suggesting the following: When you jig your fuselage, attach the motor mount to the firewall, and jig that as an assembly. In assembly, attach the floor ribs to the 063 angles previously riveted to the firewall with #8 washer head screws, same # and spacing as rivets. Due to the method for attaching the inner/upper gear leg mounts on the -4, any minor mis-alignment here will stress the firewall/floor rib area. If you have your fuselage already built, shim the area mentioned to take up any slack- do not simply tighten the bolts. Comments? Check six!

Subject: Re: Upside down flap hinges
The step created by the hinge is rounded and located well back on the surface of the wing where the boundary layer begins to thicken. The frontal area is 7 inches (.05 ft^2). The equivalent flat plate area is the product of Drag Coefficient CD and frontal area. It is the latter that slows you down. I would be surprised if CD for a step like this was greater than .1 giving a flat plate area of .005 ft^2. At 175 knots the dynamic pressure is 103 lb/ft^2, the drag of this excrescence is on the order of .5 lb. Total airframe drag is about 200 pounds. You probably wouldn't notice it. Since you have the quick build kit and have not developed the shakes at the thought of having to do yet another thing over, go ahead and fix it. Besides, it builds character. Drilling out AN426 3 rivets is not too difficult. Practice on a dozen set in scrap first. Either a new hinge or a .063 packer under the original will restore the surface.

I have a "blow hole" in my installation. However, I've seen homebuilts certified that do not have this "whistle notch" (but then, I saw a RV-6A certified that didn't have the two bolts holding on the mechanical fuel pump safety wired. It didn't have the blow hole either. Guess the Feds can't inspect everything). When the discharge is located 1/4" from the exhaust pipe, I don't think there is much chance of a freeze up and just because there is a whistle notch does not mean that the system is 100% protected from freeze up. Also, putting the notch in the tube might not be as easy as it first seems if you are going "by the book" . It seems that I've read that there is a specific size/shape and/or location that these should be for proper operation. Can't remember where I read the specs. The best way I've found to prevent condensation from freezing in the breather line is to fly the dickens out of the RV-6 and burn that moisture out of the oil:) It's worked for me, so far, anyway.

Subject: Upside down flap hinges(comment)
Date: Sep 17, 1996
I'm getting ready to install the flaps on my quickbuild RV-6A when I notice that the factory installed the piano hinge upside down... on both flaps. The hinge extends about 1/16" below the wing, when it should be tucked up inside the wing. Hmmmm 1/16" times 56" flaps times 2 wings equals 7 square inches of drag from this little factory snafu. What would you do? Drill out 80 rivets? Accept the drag? Comments welcome! Thanks, Tim ------------------------------- Capt Tim Lewis Kelly AFB, TX 210-442-4237 lewis2(at)mailcenter.cmet.af.mil or capntim(at)aol.com COML ASEL IA RV-6AQ #60023 ====================== Hi Capt Tim, I think I would go ahead, drill it out and install it correctly. Simply because when you'll wash your award wining bird the rag will snag on the end of the hinge....... This will come to annoy you. Besides it will look better and you have confidence knowing you did it right. Am I picky are what? ps. don't forget to rivet the new hinge assembly in with the pin and opposite hinge in place to help keep things lined up. happy building Greg Bordelon greg(at)brokersys.com begin 600 WINMAIL.DAT M>)\^(@0/`0:0" `$```````!``$``0>0!@`(````Y 0```````#H``$-@ 0` M`@````(``@`!!) &`"0!```!````# ````,``# '````"P`/#@`````"`?\/ M`0```$D`````````@2L?I+ZC$!F=;@#=`0]4`@````!R=BUL:7-T0&UA=')O M;FEC``,P`0```!8```!R=BUL:7-T0&UA=')O;FEC.@$````"`?8/`0````0````````'/#7,N8V]M M```#``80@'B:(@,`!Q!L`P``'@`($ $```!E````24U'151424Y'4D5!1%E4 M3TE.4U1!3$Q42$5&3$%04T].35E154E#2T)524Q$4E8M-D%72$5.24Y/5$E# M151(05142$5&04-43U)924Y35$%,3$5$5$A%4$E!3D](24Y'15504P`````" M`0D0`0```"@$```D! ``3P8``$Q:1G7-M6]-_P`*`0\"%0*H!>L"@P!0`O() M`@!C: K 1;V8FT')A'T"G`U(@800`(&PK\'0E,$$D1W-N869U M*)%7;2/2=RQ""H5Y"& FT3^<($0%$"!!*@(X,!]0M&EV$ (2 *A0J%XRC `'!KM,D*@,C/.-PJ%)3 #\3) `, #$" ="ZY-8 N;0,1"H4%L6,@ MT/,", =P0&$&\$2P`W _UDA/34P5,%-%1[!)!D$*A2(C42 C-C!^,$,`"H<+ M9!;Q"_(=X2#./4LO2W(['$AI0#<\77Y)-!(\($[Q-C,>T!_08?\@@!^ *X S M@#>2*_$J`@!P_R(`'_8K\06A&I ><$' )T"^4P=P"U ?H"J@1B!U$;#+(G0V M\2<@07=A+" VXCT%P&%4P L@*S(?(F)I_U61('(SD@/P($$U81] (1'_('(I MD3-"('(F$R0)J$$("OQ5P,: M(/YO3V JH ) !)!18S;R$8!S.&!246YF)J$R\""0:S\C4"M"-N0FH"OB!1!G M:/]$\!4P'L!/`"6P(: ?H#*B.R* (^ _.QPHX1^R.$,@ M8V[_!]$F%%30$; &T$'!"X K,0\@<"5E`Z!1"$F-&+(!

Text item: VERY BAD TASTE. I HAVE A HUNCH AS TO WHERE YOU'LL BE DOING YOUR TIME. A heavenly scene in the far distant future: Van went to Heaven upon his death and was given a warm welcome at the Pearly Gates. St. Peter, after completing the formalities, asked him how he would like to spend his time. Van, the great inventor, asked to see some of the inventors before him. So St. Peter printed out the list of all the inventors currently (doing time) in heaven. As Van started to go through the list, he came across the name Adam. He queried if it was the same guy who discovered Eve, the woman. St. Peter confirmed that indeed Adam was the man credited with the invention of women. Van requested an audience with Adam, as he had a few things to straighten out with him. When the scheduled meeting took place, Van was all over Adam, attacking him for the flaws in his invention. "Your invention is the most stupid work of engineering I ever saw. There is too much of front end protrusion, the rear end wobbles too much, it chatters at high speeds and the intake is placed too close to the exhaust." Obviously, Adam doesn't like it too much. He thinks for a while and then leads Van to the Celestial Computer. He works with the enormous data-banks and in a few minutes there are beeps and all that, and out come a few charts and graphs. "Look here, Van. Despite all the flaws you pointed out, data shows that there are more men riding my product than yours."

Subject: Re: Upside down flap hinges
If you choose to drill out the hinge, I would replace the hinge because 1) you'll never get the holes to line up and 2) the hinge is very soft and it will deform somewhat from drilling it out. It really isn't a big deal as long as you still have full range of motion (40 degrees) of the flaps. When you re-drill AND rivet the new hinge make sure that you have a pin a piece of hinge attached to the new piece. Additionally, if the hinge is already installed on your flap, make sure that you allow for the placement of the flap and how it relates to the edge of the wing and the aileron. If it bothers you, change it. Drilling out the rivets is easy from what people tell me, luckly I have never had to do it :).

You also need to be sure to not squeeze one of the hinge eyes as you rivet. 5) If you do decide to redo it: I got much better results on my second flap by using the following process: - have the flap completely assembled except for the hinge rivets. - mount the flap to the wing by clecoing each end of the hinge, than 1 cleco in the center of the hinge (on both the flap and the wing). - I then clecoed every hole on both the flap and wing, working from the center out and moving the flap around quite a bit to try and make sure the hinge had as smooth movement as possible. - remove the hinge pin to separate the flap from the wing. - remove a single cleco at a time and rivet that location, again working from the center of the hinge out to both edges at the same time. After using this process, I can insert both halves of the hinge pin into the hinge almost the whole way just using my fingers. My first flap requires spin- ning the hinge pins to get them in. Note that I split my hinge pin into two pieces and removed three of the center eyes of the hinge. I may eventually remove a fourth eye before final assembly.

How much did you pay? >------------------------------------- >Cecil Hatfield >cecil@altonet >RV-6A (wings) The ratings are obviously maximum measurements centered within the focused beam. Consider the following: Take one of those little "Mag Lites" and unscrew the reflector assembly so that all you have is a bare bulb. Now, hold it up for someone to observe from, say . . . 2 miles away. What's the probability that it can be seen? If someone knows exactly where to look, they might pick it up . . the human eye is an amazing sensor system. Now, put the reflector back on and focus for tight beam. Point it at the observer again. I'll suggest it can be picked up quite easily. Now, what does the reflector do for the lamp's light output? Obviously, NONE. The difference is that a larger portion of the lamp's total output is launched in the same direction thereby increasing apparent intensity. If a light meter were positioned in the observer's light path, it will show a great increase in measured candlepower. Getting back to the advertisement in question. Even if they did meet their claims of 1,000,000 c.p. output, you gotta believe it's pretty tightly focused. If anyone is interested in practical, non-traditional landing lights, consider the newer, tiny rectangular headlamps for cars. They have two filaments (built in spare bulb) . . . it may not point as high and tight as the "landing" filament but it beats the socks off of landing with no light at all. Second, they have excellent life characteristics and they're cheap compared to "aircraft" sealed beams. Put one on each wing and have a really dandy landing light setup for only 110 watts of total consumption and excellent redundancy. I've landed dark airplanes lots of times . . . once I had my passenger hold a flashlight out the window . . . straight ahead? No, at the pavement under the wingtip. Successful landings have more to do with peripheral perceptions of height above ground than with seeing whether or not there's a cow on the runway 2,000 feet ahead. One of my builders flies his Rotax powered Kitfox a lot at night. His landing lights are small, 25 watt fixtures under each wing tip pointed straight down. I subscribe to several lists and get lots of e-mail on aviation electrical systems issues. Landing lights versus human factors has to be pretty high on list of misunderstood requirements. I'd trade 25 watts of light spread around the area just in front of and under the ship for 250 watts of klieg-light down the centerline any day. Bob . . .

Subject: Upside Down Flap Hinges (Comment)
I would highly recommend not changing the flap hinge. A little known secret for the reason it was probably done that way is because the flap was probably butted up to tight against the top wing skin. Changing the hinge gives you an extra amount of room to have under the top wing skin if the flap is rubbing up against it to hard ( slightly pushing the top wing skin up ). Granted the slight alignment problem should not have occured but it is easier to fix then redrilling the flap brace to the correct position so that it does not push out the top wing skin out. I have seen this done on regular kits when only a slight alignment (empahsized slight !) change was required. As to the drag that far aft and small amount on the wing, it will be unnoticable.

Subject: re: rv8 elevator clearance
I don't know who sent the message (I lost it in a case of terminal computer klutz) re: binding of the elevator leading edge against the spar straps of the HS, but here's what I know. Hope it helps. The leading edge can bind if the rod end bearings are at the prescribed 13/16" and the distance from the inboard end of the spar to the leading edge is any greater than shown on the detail on drawing 5PP. There are at least 3 fixes: (1) back off on the rod-end bearings (1/2 to 1 turn should leave enough thread engaged). (2) put a greater bend on the leading edge skin at the inboard end. This can be carefully done without removing any pop rivets if you don't need much additional clearance. (3) drill out the pop rivets, abandon the pre-punched holes and drill new holes with greater skin overlap and therefore a spar to leading edge distance as per the drawing. Another thing you might check while waiting for the wing kit: my elevator control horn interferes with the HS spar flange before the elevator reaches the prescribed 20 degrees down. Checked with the factory and was told that no previous RV-=8 builders had called on this, but that some -6 builders had encountered it and the fix was to file off enough of the spar flange to allow full control movement. Good luck. George RV-8 sn 80006 ________________________________________________________________________________

Subject: fuel pump location
I am tinkering with my fuel system while waiting for the replacement fwd fuselage skin to arive (see earlier canopy trimming saga). Having liked the RV's I saw on the flightline which had no center console for throttle, mixture, etc, I have duplicated the idea on my plane. My detatched, floor mounted console has two fuel gauges and the selector valve installed. I plan to conceal the Facet pump inside this console also, floor-mounting it just below the selector valve. Both the plans and the Facet instruction sheet show the pump mounted at a 45 degree upward angle, an arrangement which I cannot engineer into my chosen location. Is there a compelling reason to do it this way? Would it have anything to do with keeping the pump purged of air, or what?

They know about the problem, and immediately offered new hinges.

Many thanks to the folks who suggested that I install the new hinge with the pin inserted and the other hinge half connected (to keep the hinge straight). Drilling out the 40 or so rivets wasn't so bad. It took just under an hour. The rivets tend to hang up in the hinge, but that doesn't matter because I just need the rivets out of the skin and spar.

Subject: Alternator light
Timely notification of alternator failure is (IMHO) a MUST. Fortunately, this is a simple task based upon the following physical facts: (1) Batteries DELIVER their energy at 12.5 volts or BELOW (2) Batteries REQUIRE a bus voltage of 13.5 or ABOVE in order to recharge. Therefore, it follows that a bus voltage below 13.0 volts may be assumed a result of alternator being off line for what ever reason. Sport Aviation for August 1995 carried an article I wrote called "Ignition Battery Manager - Revisited" on page 99. There's a schematic and bill of materials for building a suitable voltage sensor for driving a variety of loads . . . in this case, providing automatic changeover of electronic ignition systems to separate battery in case of alternator failure. In addition, the circuit will Illuminate an indicator to notify the pilot of alternator failure. We're just starting a production run of the low voltage sensor described in the article. You're encouraged to provide this type of capability if it's not included as part of an engine or other systems display instrumentation. You may chase your own parts from the article, purchase a kit (loose electronic parts only) from us or take advantage of our assembled and tested units. Pricing for kits and/or assembled units will be available late next week after we've put a few together and get some good time numbers. If you think you'd like to build from scratch and don't have access to Sport Aviation, drop me a #10 SASE with the "IBMM" marked on the back and I'll send you a copy of the article. Regards, Bob . . . AeroElectric Connection ****************************** * Go ahead, make my day * * Show me where I'm wrong! * ****************************** P.S. Be wary of sensors from any certified airplane. I designed and built about 5 different varieties of those critters to Beech and Cessna specs. Unless they've produced some NEW designs that I'm not familiar with, I can tell you that NONE of those devices are recommended for the task detailed above. ________________________________________________________________________________

The master is just a ground switch so come off the side of the switch that connects to your relay with an LED, the other end of the LED needs to be connected to +12V (my LED's require a 477 ohm resistor in series or they go "poof"). Whenever the master is "ON" i.e. ground is made the LED is on. These are very tiny lights which fit in a 1/8" hole so they are not distracting during flight. I also have them connected to all my circuit switches to show at a glance the switch is on. Most car alternators I've seen have three connections (not counting the p lead). One is for ground, one is for excitation (+12) , and the last is for an alternator indicator light. It can be connected to a light that is rated for 12V and will come on when the alternator is not putting out much current (typical alt light on a car). I just left it disconnected because I am using an EI volt/amp digital meter connected through the alternator p lead. This tells me directly how many amps (+/- .1) the alternator is putting out and the voltage the alternator is holding. If I turn off the field to the alternator (throught a circuit switch) the meter tells me what voltage the battery is holding. There are other ways to connect the meter and all are explained very thoroughly in the instructions. This is the best solution IMHO. Each lead on the alternator is marked with a letter which is standard, I don't remember them off-hand but have them written down at home and will get them to you if needed.

How is everybody supporting their uprighted fuselage? For now I have a sawhorse under the firewall and tailspring (putting in seat skins, etc.). I now need to climb inside to backdrill my top fuse skins, and later for instrument/systems installation. I'm 220+ lbs. I was thinking about wooden cradles underneath each bulkhead. Overkill? A fellow lister suggested buying a troll. Anybody know where to get one of those ? After the fuse skins, I start on the wings, first step is pitot tube installation. I plan on a day/seldom night VFR setup. To those flying, should I go through the extra expense of a heated pitot tube? I've never used heat in my 200hrs, but then again So. California isn't exactly freezing. I will be flying lots of x/c.

Tim, Call Van's, request replacement hinge material and start drilling. It may not be much drag but don't accept an incorrectly built aircraft. If you're careful you can drill out the rivets without any problem. Rick McBride RV6, N523JC ________________________________________________________________________________

It >also held it level both length and span wise. I used two "heavy duty" saw horses: glued, screwed and gusseted. One went under the firewall and the aft one went under, I think, 608 (on the RV-6). I thought maybe a sawhorse under one of the wider bulkheads might be a little more stable than putting one under the tailspring area. One thing to think about. My sawhorses did not put the fuselage in level attitude. When I needed to do this, I got on my hands and knees, raised the fuselage with my back and slid the sawhorse forward until it was level. ! When you get done with your work, don't forget to put the saw horse back under the bulkhead! My rear saw horse had little wedges that kind of followed the contour of the 608 bulkhead. When moved forward, these wedges came in contact with the cirved portion of the sice skins. A friend who was building a RV-6 (and who must weigh 250 lbs.) came over and asked if he could sit in my six. Sure.---- oops. The little wedges put a crease on each side of the airplane. After he left, I hopped up and down quite a bit and cleared the air in my lungs. How did I get it out? I got a piece of broom handle, sanded the rounded end smooth, stood out side the airplane and reached in to the aft part of the fuselage and rubbed on the crease until it darn near disappeared. I figured a few tailwheel first landings would spring it back to original:) Be careful out there.

LED (Light Emitting Diodes) are "current" devices in that unlike incandescent lamps, the voltage drop across a diode is relatively constant irrespective of the light output. If you check out LED specs, you'll find that they have a "maximum" or "operating" current rating; for most single junction devices is 20 Milliamperes. Hence, a resistor on the order of 470 ohms will produce a 12v/470ohm = 25mA current. Right in the ballpark. The voltage drop for a single device is about 1.7 volts. The LED arrays you see on the backs of cars will hook several devices in series (6 devices = approx 10.2 volts) so the resistor drops to 2/0.020 or 100 ohms. For intermittent duty (like a third stop light) an overdrive value of 30 to 50 milliamperes would probably get you a lot more light without killing the LEDs. The annunciation above is a simple indication of hot bus . . . in no way is it useful for infligh failure annunciation . . . when the bus goes cold, you won't need a light to tell you about it . . . >Most car alternators I've seen have three connections (not counting the p >lead).

True . . . but current thinking about stock automotive alternators makes this irrelevant . . . there ARE failure modes within all the alternators I've disassembled that can produce over voltage runaways. Modern ALTERNATORS are fine devices and quite worthy of installation on airplanes provided you remove the built-in REGULATOR and change the brush wiring so that an ov protected, external regulator can be used. >I just left it disconnected >because I am using an EI volt/amp digital meter connected through the >alternator p lead.

No instrumentation either digital or analog is a substitute for active, low voltage annunciation. Aviation history is replete with stories where the writer says, " . . then the panel went dark . . ." or " . . . pressed the mic button and nothing happened." MOST of these cases involve silent failure of an alternator that went un-noticed until things started dying. The 13.0 lv monitor I described earlier will light the light in seconds after an alternator shuts down. >Each lead on the alternator is marked with a letter which is standard, I >don't remember them off-hand but have them written down at home and will >get them to you if needed. Standard markings of stock automotive alternators should be replaced by your own markings resulting from internal modifications described above.

Bill, This is the common local Southern Calif. method for mounting the fuel pump -- copied from Steve Barnard's award-winning RV6A. A special fitting (coupler?), with male pipe thread on one end, and a 37 degree flare swivel nut on the other end is used. This attaches the fuel pump directly to the outlet of the fuel selector valve. A cross bracket attached to the center console sides is used to support the pump. I don't think this fitting has an AN number, but is available from auto racing and industrial hose suppliers. I got one from Earl's - the auto racing plumbing supplier. It seems a much cleaner and nicer looking alternative to that specified in the plans. Several flying RVs are using this mounting position, with no ill effects. ... hope this helps ....

I _very_ carefully crawled inside (believe me, I weigh more than 220 pounds) when I had to fasten the tail end of the shoulder belts. I figured the fuselage should be able to stand that kind of force since it _is_ designed to take the shock of landings. >A fellow lister suggested buying a troll.

I have to add, though, that one time I had been flying for two hours or so around Puget Sound and decided to stop at Arlington Airport for lunch. When I slowed to pattern speed (~95 to 100 mph) I was CERTAIN that I was much slower. After flying around at 160 to 190 mph it felt like I was falling out of the sky at 100 mph. I had to keep telling my self that the instruments were right; after all, the aircraft _was_ flying fine. >Thanks, > >Rob Acker (r.acker(at)ix.netcom.com) >Rancho Santa Margarita, CA / RV-6Q / N164RA reserved > > > John Ammeter ammeterj(at)seanet.com
