      up throwing out stuff I won't use.  I have heavier battery wire and scat 
      tubing so all I'd be using is the smaller gauge wire and terminals.  What 
      lengths and gauges should I order to get started.  I'm building a 6 with 
      day/night VFR panel.  Has anyone kept track of what they used?  Thanks in 
      advance.

Subject: Re: Whelen strobe connectors question
Molex connectors come in either 0.062" or 0.093" pin sizes. The small ones are good for low power connections (trim, nav lights) and the big one's I've used for Pitot heat, Landing light and Taxi light. The Whelan strobe power supply pin (Amp) looks very similar, but is different. My good quality Molex type crimper works fine with the Molex pins, and marginal with the Amp pins. The strobe and the power supply require the use of the Amp pins. In between, where the wings attach, I've used the Molex. When I started wiring the plane, I bought a bunch of different connectors i.e. 2-pin, 4-pin, 6-pin... and the associated pins from Allied. I'm glad I did. I've been able to make every connection needed quickly and professionally. Go to www.allied.avnet.com and search on Molex. Buy your crimp tool from Bob Nuckolls.

Larry, I bought the kit.............right at $200. Like you, d/n VFR. I used every inch of wire from the kit plus have purchased quite a bit more..........and I've yet to run the wires out to the wing tips or the tail yet. I've also used every single ring connector. The pre-made battery and solenoid cables were also very handy..........save me from running around to make up my own. Although I DID NOT follow the plans (snipped every tie wrap from the basic harness and just used the wire) that came with the kit.............they were still VERY handy to give me an education in how the basics are done. If I were doing it again I would probably still buy the kit to get me started!

Randy Lervold posted a related message stating "Whelen uses the AMP Mate-N-Lok series connectors.........Molex brand connectors crimp the same way but are not compatible with the Mate-N-Lock connectors or pins at all. You will likely encounter, or want to use, Molex connectors elsewhere in the plane." Ok, I'm confused. In Van's catalog under the section for Replacement parts for strobe systems, they list "Molex Connectors" for the power supply / cable connection. No reference to any type of AMP connector. Does this mean that the power supply uses a Molex connector and the strobe itself uses an AMP connector? Does anyone have pictures on a webpage of these connectors? Is the Molex or the AMP better for all-around use on the airframe?>> Randy is right and Van's is wrong. The AMP connectors are used on the Whelen systems. People often confuse without meaning to and Van's has used the term Molex generically here (refering to the white nylon housing type cheapie crimp pin connector, kind of like calling all tissues Kleenex). -GV ________________________________________________________________________________

Tracy is starting to manufacture components such as reduction drives, electronic fuel controls, etc. so we are likely to start seeing more similiar installations. You will always have differences such as are seen in lycoming installations today. Oil coolers are a prime example of variability in todays installations. The exhaust is a problem because it is hot and noisy, but a big pipe also hangs out of piper malibus and Pilatluses. This does not necessarily detract from the esthetics. Beauty is in the eye of the beholder! Everett Hatch flew his rotary RV4 block to block formation with Van in his 160 HP lycoming and consumed the same amount of fuel. The BSFC may be a little worse on the rotary, but Everett had a pretty efficient radiator system and it is probable to make less drag with water cooling.

Sorry to read about your troubles. You can price parts easily from Van's web site: <http://www.vansaircraft.com/> Go to to Online Shopping, Accessories Catalog, and then look down a few inches from the top to find a link "the list". That will give you a text file with all the part numbers, descriptions and prices. I searched that list for canopy, and found: C-401 GRAY TINT PLEX CANOPY $529.23 C-401 CLEAR CLEAR CANOPY BUBBLE $513.85 I can't help you on the other questions, as I'm building an RV-8. Given that you didn't do it the first time, you might want to find a local builder who has already done his canopy and pay him to do yours, or at least get him to help you. I don't think that will get you in trouble with Transport Canada, but you might want to confirm with the Dorval regional office. If they give you a hard time, contact me and I'll put you in touch with the headquarters guy in charge of amateur built aircraft issues. They are currently working on an update to the regulations that should legalize builder assistance. It looks like the updated regulations will take the very practical view that it is safer to allow builders to contract out complex work than force them to do it just to meet the 51% rule. I doubt they will give you grief if someone rebuilds your canopy for you.

>>Listers at Large, >>I think I am going to disable the DNA feature soon since so many >>people have been miss-using it. Matt; I think that with all the warnings (requests) to keep messages short and not clutter the archive that people tend to err on the side of d* no* archiv* to be kind to your server. Also it is sometimes difficult to decide wheather the information a person thinks they are giving in a response is valuable, or if it is just a quick offhand reply or thought as opposed to a well researched answer to the problem or question of the original poster. As to the original poster not archiving their post, they may feel that it is their own small personal problem without realising that their question may be the same one someone else had but didn't verbalise or that it is of interest to others. I have responded to the list a few times with information I thought might be usefull to the thread and used the DNA feature because I didn't think my lowly thoughts were of general interest. I have on a couple of occasions received replys such as yours asking why I did that. In all of my cases it was out of ignorance and when requested reposted without the DNA message. The ones that particularly bug me are those that repeat the whole of the original message or even part of the whole thread, or those that go on forever chasing an obvious joke without the DNA. My two cents on the subject Matt and we do appreciate this forum even if it is miss-used from time to time. Bob McC ________________________________________________________________________________

The advantage we have with the Jabiru is that the manufacurers of this new engine are looking at the RV for it's intended use. They already have mounts and firewall forward kits for other homebuilts. I'm sure they'll follow through with a mount and kit for the RVs as well. I'm betting they don't have to, if Van really is looking at the Jabiru for his installations. There is one thing we did miss during all of this discussion. No one has mentioned provisions for a vacuum pump. Many of us, if not most, use them.

This is what I will do also. I guess it is possible to dimple the rib, rear spar flange and skin but since I assembled the box without dimpling any of these parts I have no choice. I can't see any reasons why a countersink of the rear spar at the rib intersections wouldn't work. If you're uncomfortable with the countersink, you can dimple the skin and carefully remove the 'backside' of the dimple with a dremel tool or a small file.

I find it hard to believe that anything that is bolted to the engine case really benefits from blast cooling.

Ed, I have tubes going to mags also and I am not convinced they serve a purpose because there is no shroud. My fuel pump has a shroud around it and I think this is effective. I think the one to the alternator is worth while, its is not sinking into the engine and is below the air flow. Anyway the whole engine is cooled by a big blast tube.

Subject: RV8 Trip Report: Albuquerque to Spokane (long)
Date: Apr 15, 2001
Listers, My trip a few days ago in the RV8 to the Pacific Northwet..uh...northWEST was quite successful! Had a great time and saw some wondrous sights. My backseater for the trip was Gary Seaton, who, after flying with me last year, decided he just had to have an RV. The purpose of the trip was to take Gary to Revelstoke, B.C. to meet with Homer Rogers, builder of an awesome RV-6A for sale. My job: fly Gary there, and do a pre-purchase inspection and flight evaluation of the airplane. Both went exceptionally well. Homer is a terrific guy and builds a fine airplane. We struggled on the way up there to find VFR weather along our chosen route. First stop was Page, Az. Wx was down to yucky VFR upon arrival. We landed, fueled up, and got a ride into town for breakfast. The scud cleared up nicely to a low, scattered layer that was easily topped for our departure. Off we went to Ely, Nevada for the next fuel stop. Yet again, more snow, rain and low ceilings. It was the kind of weather that looks really dreadful from a distance, but sorta dissolves as you get near it. Visibility was just fine but it was COLD! It's still wintertime in some parts of the country! We touched down in Ely, tanked up, checked the charts and weather ahead. The same type of random showers and mist was forecast all the way up to Washington, with improvement farther to the west. Next stop was Nampa, Idaho. Our route took us up over Elko, Nevada, then a slight northerly swing to Nampa. Pretty decent weather and looking better by the minute. More fuel, a few cookies for the crew, and off again. Next waypoint was Baker City. Visibility very good, but had to make the choice: over the top for a smooth, clear ride, but man it's cold up there! Or, down under it, a bit warmer, but have to dodge the occasionally semi-obscured mountains. We did a bit of both. The cabin heater did help, but not much when the canopy shrinks from the cold and every little air leak feels like a blast of arctic air. Gotta work on that. We passed Baker City and pointed the nose at Davenport, Washington. The going was good...very good in fact...until we neared the Oregon/Washington border. A huge wall of misty, blinding white cloud that had no top in site was ahead of us. The sun was lighting it up like a flashbulb and I just could not see through it. So, while constantly looking over my shoulder and down to assure myself that we could get into visual conditions, I started a climbing ascent to see where the top was. After an inspiring RV climb to 14,000', I'd had enough. Still couldn't see through it. The view below and behind was still wide open. "Gary, I think we're done for the day" was my comment. A course reversal and 15 minutes later, we were descending into La Grande, Oregon. Blew the first approach...after the wind sock swapped ends on me on final! Don't ya just hate it when that happens? The next shot at it went much better, but I'm still totally amazed at how the airplane handles closer to sea level than where I typically fly. It's like the wings are filled with helium! I was a slipping madman most of the trip. Kept coming in too high. We stayed the night at La Grande, and returned to the airplane Friday morning to find it covered with a mixture of snow and ice from the precip of the previous night. I put my back seater to work brushing it off...ALL of it. The skies were clearing and off we went. The flight into Washington was simply stunning. Perfectly smooth air and unlimited visibility. Yet again, that changed! Next waypoint was Davenport, then a right hook around the Spokane airspace into Deer Park. More scud, and showers. I pulled some power to slow down to give me more time to make a decision and a 180 turn if necessary. The Davenport airport looked largely deserted, so we continued on to Deer Park. The clouds were definitely low, but seemed to open up as we passed. It was magical. Beautiful terrain, light rain, and occasional bits of sun. We landed at the Park, and also found nobody home. One grumpy A&P type working in a hangar was absolutely NO help at all. We did find the small building that housed a bathroom, charts, coffee, and such. After a few minutes there, Bill and Penny Loomis, the managers, arrived. These folks have got to be the nicest, most supportive and downright wonderful folks in the airport business! They helped me assess the weather situation, from an experienced, local viewpoint, and even called up Castlegar flight service for a weather briefing at our intended Canadian port of entry. Synopsis: VFR not recommended....REALLY not recommended. When I hear terms like "snow pellets, rain showers, mountain obscuration, or visibility less than one mile"...I tend to listen! Bill and Penny mentioned that we consider driving up there..in their loaner car! Done deal. I made my "no-go" decision, we grabbed a quick sandwich at the Subway, and onward to Canada we went. Oh, one more thing, they pulled their Champ out of their hangar so that I could park my RV for the night. WOW..these folks are awesome. Gary called Homer with our plans and Homer agreed to fly the plane down to Castlegar to save us all some time. We drove the three hours up through customs and into Castlegar, B.C. What a drive, and the views were exceptional. Just as Gary was preparing to call Homer's wife, I looked down the flightline and saw...Homer's airplane! He had arrived mere minutes before we did. What timing. I looked the plane over, and mostly admired the craftsmanship and cleverness of Homer's construction skills. Many improvements were made and all were executed with great care. I hopped in the right seat, with Homer in the left and off we went down the river. WOW...we don't have views like this in New Mexico! A few turns, stalls, and we were headed back. I landed it. Man, whatta groovy RV. On the ramp, Homer hops out, and tells me to take Gary up. "HUH!?? ME?? I thought YOU were going to take him up?" Was all I could say. It all went very well, It's just an RV afterall, and handles wonderfully. In fact, I landed it better than I land MY OWN AIRPLANE! Gee, what's up with THAT?!? (NO comments on the training wheel debate, K?) The synopsis of the deal: Gary bought the airplane. Delivery or pickup of the plane will happen at a later date. We flew home in MUCH better conditions, and with a decent tailwind that allowed groundspeeds of 195mph+ most of the way. Total flight time back home along the same route as we came up: 6 hrs., 51 minutes. Keep building your airplanes, folks. The world opens up to you when you fly an RV!

You Go, Boy! The ergodynamics of the aircraft cockpit and further anthropogenic/physiologic considerations are becoming a very important part of aircraft design and accident investigation/prevention. Some of these little things can matter very much under certain "stressed" situations and even under "normal" situations (ie, the location of the fuel selector valve on John Denver's newly acquired aircraft). Also, remember cockpit procedures, communications and POH instructions (remember the airliner that went down over southern Florida because the whole flight crew was trying to trouble shoot a warning light and no one was flying the 'plane?).

Subject: Re: To serif or not
Serif fonts are generally used in print sizes of 12 point or smaller, to make reading easier. They make reading easier because we read mostly by recognizing the overall shape of each word, not by parsing individual letters, and the little horizontal strokes (the serifs) help tie the word together and visually separate it from the other words. (We only parse letters when we encounter an unfamiliar word. This is why it's so easy to miss a small error, such as "spoof" instead of "spool", when proof-reading. The overall shape of one word is much like the other.) But this theory is about how we read lines of text, and serif fonts are used to aid reading lines of text. If you are using labels (single words or short phrases) the advantage of serifs mostly disappears. This is referred to in publishing as "display font," and is generally san-serif. A better way to go with labels is to use a larger font, and not worry about the serifs. An aside: serifs were invented by the Romans, as a way to avoid cracks caused by stress concentration at the ends of strokes when they chiseled characters into stone. That is why serif fonts are often referred to as Roman fonts, to this day. Tedd McHenry Surrey, BC -6 ________________________________________________________________________________

Did the friend have any problems before he installed the new engines? Is it possible that he may have done something during the installation that has impacted the system? You say he isn't getting support from Jabiru. Have there been good tech sessions or have they been heated? This alone can cause some difficulties. Like you, I'm not trying to throw flames, either. I look at this as something that would be nice for you to look into for us a bit farther, if you don't mind. We don't want to judge an engine by one person's installation. I've seen some bad and good ones, even with my limited access to those projects of others. However, if his installation is good and the support bad, we need to know that up front before we start sinking dollars into a bad deal. So far, the majority is in favor of this being a good engine. In the meantime, I've got a friend in England who has a Jabiru airplane fitted with what else. :-) I'll contact him and see how his engine is doing.

My Cheetah, which is very much like my RV inside the cowl, did not have any blast tubes. During my over nine years of ownership, the only problems I had was with some vapor locking when I let the hot engine sit for a few minutes and with my having to replace one vacuum pump. Everything else was just fine. I did have to replace the mags; but, they were the throw away Slicks that were supposed to last 800 hours. Mine lasted 1200 and 1400 hours. Not bad for throw aways. Oh, yeah. The battery and contacters were out there in the heat, too. The vacuum pump lasted well over 500 hours before it bit the dust. I consider that just fine for a dry one. My RV-6A has some blast tubes to the electric and mechanical fuel pumps to help slow down vapor locking. I've considered other blast tubes; but, I've not put any more on it. So far, no problems in 90 hours. That doesn't mean I won't. Jim Sears in KY ________________________________________________________________________________

My opinion for what its worth. Order the standard way, especially if space is a factor. Tail parts first to hone your skills on cheaper parts. Then the Wing Kit. The wings, when finished are easier to store out of the way while building the fuselage. The fuselage takes up more space.

I'll bet that a Lyc data sheet will say just about the same fuel burn for an O320 at full power. Was that at sea level or full throttle at 8000 ft (75%)? Most of the rotary's legendary poor fuel economy is at the very low power settings used in autos. Tracy Crook (the RV-4) has flown his for around 1000 hrs. He can fly with 180hp -4's with almost identical fuel burn, & his plane is probably 'dirtier' than most -4's which really hurts when you are in the 200 mph speed range. Those long exhaust pipes actually look about like the 'swiss muffler' that is very common in Europe to meet noise standards over there. Muffler design for the rotary in a/c is evolving rapidly now, & that issue may go away soon. I agree that the engine installation will be more difficult, but to me, there is a lot of frustration flying with a 40 year old engine (70 year old technology) using a farm tractor carb & ignition. I'm not going to dismantle my flying a/c to install one, but when I build, I'd love to try it.

Facet/Purolator only recommends mounting with the outlet higher than the inlet to aid in purging vapor. There is no specific angle specified. If you want to contact the manufacturer for specific recommendations here is a link: http://www.facet-purolator.com/connect.htm However, do not mention that it is for an airplane as they do not condone the use of their pumps in aircraft due to liability concerns.

Just a number I heard. > > > > Jim Sears in KY > > RV-6A N198JS > > Hi Jim, Being one of the four rotaries at Sun & Fun (the blue/white and red RV-6A), I agree that there is as yet no "cook book" approach to installing one. However, the way we will eventually arrive at (or close to) a "best practices" approach is to try a number of different ways and then hopefully close on the best way. We are all sharing our results with others so they can move further toward this goal than we have. At this stage, I would agree that this is not for everyone as you must be willing to experiment and redo. Certainly there is a degree of risk, just as there is with any engine - including Lycomings. We are convinced that the engine itself presents very little risk, the rotary is inherently more reliable than any reciprocating engine. The reason is there are no connecting rods, pinions, valves, valve springs, camshafts, and other things that can fail in a reciprocating engine and of course none of the inertial loads of pistons changing direction many times a second. However there is risk, but it primarily lies in the auxiliary systems (fuel, coolant, oil, etc) that we each designed from scratch. I will be the first to say that if you want to fly, put a Lycoming in your bird and enjoy. If you like a technical challenge then this may be your cup of tea. Your comment about the installations all being different is certainly correct, although the underlying principles and concepts are probably closer than their implementation would indicate. Actually, the different installations actually show that any number of approaches will get you in the air, now we are trying to nail down the "optimum" approaches and practices so those that may want to follow will have it somewhat easier. As with any Lycoming powered RV, the performance depends on the airframe and propeller combination as much as anything. But Tracy Crooks Rotary Powered RV-4 (which is not as aerodynamic clean as it could be) will leave just about any 180 Lycoming powered RV in his tracks. My maximum calibrated True Air Speed to date is 192 MPH at 1656 lbs Gross weight, certainly not the fastest RV-6A, but respectable. Lastly, I agree that the current mufflers you saw are ugly - although I am trying a variation on the "Swiss" muffler that hopefully will not be as bad. But once again we four at Sun & Fun have agree to take different approaches to see which one comes closest to the idea of a light weight, effective sound reduction and without hurting performance more than necessary. We have certainly found some approaches that did not work but others look more promising. For your information, there is one firm that is producing FWF rotary engine installations specifically for the RV and that is PowerSport. However, at the moment their installation is a bit pricey in my opinion. For that reason, most who want a rotary powered bird will have to roll their own for the time being. But anyone who is interested can check their web site at http://www.powersportaviation.com/ Tracy Crook's site is filled with information about rotary engines and also products if you want to roll your own at http://www.rotaryaviation.com/ To my knowledge, there are 8 RVs flying with rotary engines at the current time with approx 12 more RV projects with rotary engines in various stages including several 3 rotor engines in RV-8s. Rotary engines are also flying in Long EZs, Cozys, Velocities, GlasStars, Coots, and one in a Grumman Tiger as well as other airframes. This is what experimental aircraft building is all about. You can draw your line wherever you want to. Most folks will draw the line at an experimental aircraft with a certified engine and some of us have the inclination to push the line a bit further.

For most side by side folks, it'll be your right hand (you ALWAYS need a hand on the stick, but there are plenty of times when your throttle hand is free for other tasks). For everyone else, your left hand is the free one. Place the switches you're most likely to use in flight, or those that you may need to get to RIGHT NOW in the easiest to reach location for your "free" hand. In my case, I deemed that the fuel pump, trim servo kill, and landing light switches are the ones I'd need easy access to during flight (and especially in the pattern). If you have a panel located trim switch, it should also be easy to reach with the probable free hand. Like Ed said, group the switches, with the critical ones in locations which makes them easiest to find by braille. Any other switches (mags, starter, primer, internal and external lights, etc...) need to be logically organized. In my case, I've got the master, starter, primer, and ignition systems in a group, with lights in another group. If you can locate switches to the throttle quadrant or the control stick, that's a huge bonus, because you don't have to turn loose of anything to operate the switches or flight controls. Obvious candidates are transmit, trim, and flaps, but the more you can add, the better, within reason. One thing you should absolutely try to avoid is cross handed operation. You do not want to have to reach across your body to operate a switch, nor is it good to have to switch hands on the stick to operate a switch. It can be difficult to avoid these problems entirely, but you should not accept them on flight critical items (fill in your list of flight critical switches here). A final thing to consider is dexterity. If you really, really, need to use your dominant hand to operate those little buttons and switches on your radio, you might as well locate the radio near your dominant hand. Operating a radio in turbulence can be tough even with your "better" hand, and may be impossible with your non-dominant hand.

This was attributed to the gear box which had no thrust bearing and therefore put excessive thrust loads on the engine thrust bearing. Lycoming power aircraft of course make more off-airport landing than any other power plant simply because their are many more aircraft powered by Lycomings. Yet, most folks would not hesitate to put a Lycoming in their aircraft. Just as in any installation with a Lycoming, any auto conversion success is to a great deal dependent on the thoughtfulness and quality of the installation. Certainly, I am not advocating that anyone give up their Lycoming for auto power, it is simply not for everyone.

Date: Apr 16, 2001
I just had the opportunity to drill out the hinges that hold the two halves of the canopy together and thus do a destructive test of the practice of bedding the hinges in fiberglass mat. The results......it did very little.....doing it like I did. After drilling the rivets out, the hinge separated from the fiberglass with little resistance. The mat firmly bonded to the cowl This is how I did it. Sanded the cowl and hinge Drilled 3/16" holes in the hinge between the rivet holes so the fiberglass could squeeze through Used two thickness' of fiberglass mat Used West System epoxy resin When I riveted the hinges on, little to no mat came through the holes I drilled for that purpose. I am reinstalling the hinges and am doing the following Sanded the cowl and hinge Drilled 3/16" holes in the hinge between the rivet holes so the fiberglass could squeeze through Used three thickness' of fiberglass mat Used polyester resin Put down a layer of resin/microballon/thickener under the hinge After riveting, covered the hinge with the same resin/microballon/thickener I switched to polyester resin because I heard somewhere that the mat may not be broken down as well using epoxy resin I used the microballon paste to get some bonding through the 3/16 holes I drilled. I hope I won't have to do another destructive test. I hope it does something because it sure is a pain riveting over fiberglass!!!! Now, for those inquiring minds that just have to know......the reason I had to tear out my hinges is that I installed them with the wrong angle. I have one of the last of the OLD cowls and didn't have the instructions for tilting the hinge to get the zipper effect. I did the zipper thing not thinking that it mattered which way the zipper went. I had it so the hinge eyes extended down from the aft of top cowl and then hidden at the front of the top cowl.....wrong! I couldn't get the top cowl back on after I riveted the side hinges on. Once I saw how the geometry of the thing works, I realized that the hinge eyes need to be switched so the eyes are hidden at the aft of the top cowl and then exposed at the front of the top cowl. Now you know. Ross 6A....if I only had to build it once, I'd be done!!!! ________________________________________________________________________________

Subject: Re: Which kits to buy first
If you're new to sheet metal work, you'll want to start with the emp since a mistake won't be all that costly. While I hope you don't actually make a mistake, it's always possible while you get the hang of the various construction techniques. For that matter it's possible any time, but you get my drift. Next you'll need the wing kit before the fuse kit since some of the fuse parts come in the wing kit, namely the longerons and the main bulkhead, the one that mates with the wing spars. This bulkhead is matched to the wing spars and has so has to be shipped with the wings. You'll not get very far on the fuse without these parts. Then it's fuse and finishing kit. I ordered both at the same time since assembling same together made more sense to me. For example, getting the fuse on it's wheels as soon as possible so can move it around the hanger more easily, even before the tail has been attached. Oh, and before the replies start flying, yes I know, I'll have a balance problem if the engine isn't on there. Got a plan there :-). Have fun and good luck.

As an aside to the other comments. I purchased the wing first since I had already built a tail and part of the wing for an RV-6. thought I would jump in and build the RV-9 wing and go back to the tail later. There are references to certain drawings and procedures in the wing instructions that assume you already have the tail kit and drawings. Mostly around how to do the trailing edge pieces and instructions apparently located on drawing #5 that comes only with the tail kit. Not a big deal since I could imagine what was being referred to, but an indication that Vans kind of expects you to go in order. Their recent completion of the full preview plans would alleviate the item that I had I would expect. In any case, I'll probably order the tail next.

Listers, After a search of the archives, I didn't find an answer to this particular problem, so here goes: I laid my gap fairing in place and the aileron rubs on it. After riveting, will the gap fairing tighten up to the rear spar and leave room for the aileron to move? If I rivet the bottom side of the fairing to the rear spar and drill the top side to the skin and it still interferes, will I be able to adjust the fairing? Am I being obsessive (again)? I haven't seen anything related to this issue, so maybe it will be fine once it's riveted in place (hope, hope). As usual, many thanks in advance for all the great help I've been getting here.

Jim, On my -6A, I had to trim the top flange f the fairing, where it goes under the top skin, quite a bit, over 1". It seems to me there is a drawing about this and you have to compute the dimension to make the spacing correct for your wing.

Microbaloons makes a lousy filler for anything but thin, cosmetic applications, where the item is not subject to flexing. It will make the resin weaker not stronger, and should not be used as a bonding agent IMHO. Instead use milled glass or at the very least, cotton flox. Either one will make more of a structural bond. If you bond your hinges with a slurry of milled glass fibers and squeeze that stuff through holes in the hinges I'll bet you won't be able to get it off. Also, when you say you sanded the hinges, do you mean you really SANDED them? I mean, with 80 or even 60 grit? That's what it takes to make the stuff really bond with aluminum.

Subject: polyester over epoxy
Mickey: A couple suggestions re your plan. Firstly, polyester does not bond well to epoxy. If you want to go to polyester, get the epoxy off. As an alternative, West System makes another epoxy which is formulated for wetting and bonding glass. It is a little nastier than the normal WEST stuff, so wear gloves, but it is superior to use. Secondly, microbaloons are not a very strong filler. Milled glass fiber or colloidal silica will form a much stronger fill. Milled polyester fiber is also stronger than microbaloons, but not as strong as the above. The compromise is that they are heavier and harder to sand. This application requires more strength. Gougeon Brothers, the West guys, are a good source for this stuff as well. It sounds like a report of stuff done rather than a plan. Hope it works for you. Ken Smith Old RV6 kit sitting idle.

17, 2001) at 04/17/2001 08:42:23 AM It sounds like the failure you describe is an adhesive failure (as opposed to a cohesive failure). The bond failed at the interface between the resin and the aluminum. (A cohesive failure is the structural failure of one of the adherends, not the bond interface.) Assuming this is the case, adding fillers to the resin, structural or otherwise, will not improve the performance of the bond. In general, laminating resins such as West System resins are not recommended for structural bonding. Aircraft Spruce and others sell structural adhesives for these applications. I would recommend a paste-type adhesive to provide good gap filling qualities given the likely interface between hinge and cowl. Probably more important than the adhesive selection is the surface preparation. Sanding is good, but I like to precede sanding with a degreasing step. After degreasing and sanding, I acid-etch the metal parts with Metal Prep 79. After etching, it is critical to rinse, dry, and bond the parts in rapid succession. A freshly etched surface is very good for bonding, but it is not stable in air. It will quickly oxidize which will result in a poor quality bond. After rinsing parts, you can dry them quite quickly using kitchen oven or hair dryer/heat gun. Of course, as soon as a part has been degreased, it should be handled only with gloved hands. The aerospace industry had developed techniques for treating aluminum surfaces to provide good bond qualities and good shelf-stability so it is not necessary to make bonds immediately after preparing the surface. Unfortunately, these techniques are expensive and require nasty chemicals.

I have one of the last of the OLD cowls and didn't have the instructions for tilting the hinge to get the zipper effect. I did the zipper thing not thinking that it mattered which way the zipper went. I had it so the hinge eyes extended down from the aft of top cowl and then hidden at the front of the top cowl.....wrong! I couldn't get the top cowl back on after I riveted the side hinges on.

Folks, I just want to jump in here and offer some input on what causes hinge eyes to break... It sure doesn't hurt to glue the hinges to the cowl while riveting them on, but the hinges not being strong enough or bonded well enough is not the problem. In the instructions for the baffles, the directions say to have a gap about a half-inch between the baffle and the cowl. I think that's too close. One of the things I will do differently on the next project is increase this distance to no less than an inch, especially around the front of the engine where things shake the most. The problem IMO with having the baffle edges too close to the cowl makes the baffle seal more rigid, and the obvious result is vibration of the engine is transferred directly to the cowl. And then you get broken hinge eyes. Watch any airplane during shutdown and you will see how much movement there is. A larger gap there with a bigger "flap" of baffle material will still seal quite well, and will reduce the amount of vibration transmitted directly to the cowling.

Listers, I have a question regarding how much he engine will move during normal operations. I am installing the top cowling around my O-320 H2AD engine in my RV-6A and of course I must modify the cowling slightly to clear the two buldges in the engine at the top front (fuel pump and prop gov. pads). I have modified the cowling and have created about .50" to .75" clearance. Is this enough?

Subject: Re: Inclination on fuel pump
Garth et all, The primarily reason for the inclination is to help the pump purge any air or fumes that may get in the fuel lines, such as when a tank runs low. There is no ball valve used in these pumps. Instead they use a rounded spring loaded disk valve. I don't RECALL this, it is fact. Over the last 20 + years I have taken these things apart many times. As a Tech Counselor I was asked to write a paper about these pumps and their use in aircraft. I've also flown in excess of 1000 hr. in aircraft that use this pump, with little to no inclination, as the only source of fuel pressure (no engine driven pump). This post is not meant to be a personal attack on Garth or anyone else, but THE LIST would be a lot more useful, if posters would limit there input on technical matters, to what they know to be fact.

A procedure that works is to bed the hinges into a wet flox/epoxy mixture. Prep the hinge by drilling 1/4" holes between the eyes, countersink them and sand the matting surface with 80 grit. These holes allow the wet flox to squeeze out and form little mounds which act like flox rivets. If you clean these little mounds off the hinge will just peel off as epoxy is weak in peel.

Hey Eric, I would think that's OK. You will most likely pull positive g's during your flying (I do, anyway)so this will tend to pull the engine down. Also, the mounts will settle slightly after some use. I originally had about 1/4 - 3/8" clearance under my alternator pulley & the lower cowl and ended up chewing a slit in the cowl. I finally pulled the prop & put on a smaller belt. Now I have 1/2" or better clearance and no rubbing. Rick Caldwell -6 214 hrs. Looking for places to fly to and RV's to fly with, always.

Subject: Fiberglassing Cowl Hinges...destructive test
results I hope this isn't a ridiculous suggestion but has anybody tryed the closed eye version of the hinge material. I can't remember which number is which but the I believe the open eye hinge is MS20257 and closed eye extruded hinge is MS20001. The closed eye hinge seems like it would be much stronger IMO. I'm building an F1 Rocket (my first kit plane) and I plan to use the Carbon Hinge previously referenced on this e-mail thread. The Carbon hinge has closed eyes just like the MS20001 and seems like it would be a more natural bond to the fiberglass cowl halves. The F1 Rocket uses a flange and fasteners (quarter turn or machine screw) to attach the cowl to the fuselage so I don't need hinges for this part. scot > >Gary, > >You are definitely an exception.

Subject: Re: Fiberglassing Cowl Hinges...destructive test results
Meangreen, I hope it's OK to call you by your first name. I don't know if a broken eye or two is cause for replacement of the hinge. But there are many experienced RV flyers on "The List" that will be able to answer that question. If they say it's necessary, here is a relatively painless procedure that will spare your paint job. Grind off the flox mounds that are acting like rivets. Carefully slip a 1 1/4" wide wood chisel between the hinge and cowl, gently pry them apart. You'll be surprised at how weak the bond is. Epoxy is very weak in peel as I stated earlier, that is why there is an AD for the small Grumman's, to put pop rivets at the end of bond lines. Prepare the new section of hinge by duplicating the eye and hole locations. Take a Dremmel and grind the rest of the flox nubs off, then Dremmel out 1/2" approx. diameter recess where each nub was. The recess should go through the existing flox to the inside cowl surface. Lightly sand the mating surface where the old hinge met the cowl, with 80 grit. Scotchbrite or sand the hinge. Paint a light coat of epoxy onto the mating surface of the cowl and hinge. Mix up a wet flox/epoxy mixture and fill the recesses with it. Be sure the mixture is wet enough to just squeeze out through the holes in the hinge. Clamp the hinge in place, making sure there is good squeeze out through each hole. You want the epoxy/flox mix to form a domed head like a rivet. Hope this helps.

Might be because I didn't use a hinge on the bottom of the cowl -- instead put in .063 AL flanges and six #10 nutplates/screws :-) Seriously though, I think a lot of the hinge breaking could be prevented by taking the time to smooth those sharp inside corners of the hinge segments before installing, using some folded up 350 or 400 grit sandpaper.

The electric Facet fuel pumps are designed so the internal plunger rotates while in service only when the pump is mounted at a 45 degree angle. This increases the pump life by a factor of 3 according to a facet rep who recently posted this information on the Long EZ list. He implied that if tyhe pumps are installed level then they should be replaced ever 300 hours of operation. ________________________________________________________________________________

Listers, Below is a note I just got off the Grumman Gang list. Since we're already discussing alternate engines, I thought this might whet your interests, as well. Jim Sears in KY RV-6A N198JS >> Gang, I was following the discussion about an MT-Prop for Tigers in this newsgroup closely and I'm very sorry I was only able to deliver the bad news for US registered Tigers a couple weeks ago. Still, I've noticed a significant desire within the group not only to update our avionics to state-of-the-art equippment, but also to update and improve our aging power plants, hence to improve performance. Here in Europe, where fuel prices generate a stong demand for more economical engines two companies competed in the race for the first certified jet-fuel-driven diesel aircraft engine (yes, Jet Fuel for a piston diesel: Imagine the "Jet A1" sticker in a Tiger-wing!!). One company named Thielert Aircraft Engines, has now made the race and archieved FAA and JAR certification for a turbo charged diesel engine, that from it's performance characteristics, can replace O320 and O360 engines (www.thielert.de). They're putting it into PA28 and C172 airframes here in Europe right now, other airframes are to follow up. Performance, of course is impressive, range nearly doubles and TBO soars to 3,000 hrs, with an engine cost of $ 17,000 for the engine (C172N). The whole installation consists of the engine, and an MT-electrical CS-Prop. The fuel system remains unchanges, but the engine mounts are replaced, so you would probably end up with a 25k to 30k bill. Fuel consumption is is about 13 l/h (= 3.6 GALS/h) with full cuise power available up to 11,000 ft. I don't want to speculate about what numbers an engine like this will take our Grummans to, but you can figure yourself that cutting the fuel consumption by 50% will... well pretty much double the range and reduce the cost of flying SIGNIFICANTLY. So why am I writing all this and raising hopes? There is the most important aviation industrie fair here in Europe commping up next week and as a writer for a large aviation magazine I will of course meet the people from TAE as well. I would like to give these people a very rough estimate on what MAYBE the demand in the US could look like. I am considering Grumman owners as the ideal people to ask. We are usually very keen on performance and economical flying (this is why we have Grummans - right?). So what do you think?? Would you or people you know spend $20K - $25K for an engine/CS-Prop combination that is new in the market, and that well.. let's say: - Doubles your range ? - Reduces costs per hour by 65% ? - Gives you turbo-charged cruise power all the way up to the levels ? How much are aircraft owners like you willing to take the risks associated with putting an engine in your Aircraft that has not 40 years of parctical tests to look back to?? How many would replace their engine right away and how many would rather replace when the next overhaul is due?? Thanks for your feedback, BTW: I don't take orders for TAE, but my Tiger will be one of the fist ones to have a TAE engine installed if we can gather 5-7 AA5 airframes together... rgds, jb -- Jan Brill Marstallweg 9 CH-8005 Zurich, Switzerland Doppelraab-Glider D-5412 Grumman Tiger AA5B N18AP<< ________________________________________________________________________________

I'd say doing what you guys have done is the way to go...leave the hinges out of the bottom and use screws or camlocs down there. One other thing I'd like to mention is there is a lot less shaking of the engine during shutdown if the engine is at a high idle. Even with my balanced prop and electronic ignition if I idle anywhere below 575 RPM I can watch the panel shake sideways, with everything creaking and moaning. I'll notice little black trails of smoke coming from the hinges around the firewall after a flight doing touch and go's on our grass strip, but on x-country flights I hardly ever notice any smoking of the hinges. So, I can say with my experience it's not airloads that kill the hinges, it's definitely from the engine shaking. I have a small crack around the front of the carb scoop where it is bonded to the cowl, and the only way I can figure how the crack appeared is due the proximity of the airbox to the scoop (quarter-inch gap between the airbox and the inside wall of the inlet). I'd have a larger gap in there too next time around.

Subject: METO fuel configuration
Date: Apr 18, 2001
Listers, As I scramble to get all final details ready for first flight I have a question about something my DAR wants. When I do my W&B sheet with sample configurations he asked specifically for a METO configuration. He gave me a copy of the checklist he uses, following is what it says... "Aircraft weighted empty - MINIMUM FUEL. Minimum fuel for balance purposes is 1/12 gallon per Maximum-Except-Takeoff-Horsepower (METO), and is the maximum amount of fuel which could be used in weight and balance computations when low fuel might adversly affect the most critical balance conditions. To determine the weight of fuel in punds divide the METO horsepower by two. AC43.13-1A, Chapter 13 paragraph 657. 0. Maximum weight Datum line - Forward and aft C.G. with load limits for crew baggage - check figures" This is a bit confusing to me, and also I have AC43.13-1B, which is dated 9/98, rather than 1A, which doesn't even have a Chapter 13. Anyone have any idea what he's after? He was fairly adamant that I include this.

Subject: Re: Fiberglassing Cowl Hinges...destructive test results
Randall, You hit the nail on the head. It is probably the polyester resin. Polyester shrinks more on initial cure than epoxy. It is much more susceptible to vibration induced cracking as well (fiberglass wing tips, fairing etc on older certified aircraft). And most importantly it is a poor adhesive. As others have stated Microballoon/epoxy makes a great non structural filler as long as you don't mix it to dry (it won't stick well). For structural applications flox/epoxy is my personal choice. The nice thing about these do it your self filler concoctions is you can tailor the viscosity to a particular job at hand. Personal I will not use polyester resin on an aircraft.

Regarding hinge eyes breaking, Bob Haan (Homewing Group) mentioned this problem and thought he'd found the reason. When a hinge eye is viewed through a hand magnifying lens you can see stress cracks on many of them at the start of the curl from the flat part of the hinge. He dresses these with a file and emery cloth. His plane is not flying yet, so haven't confirmed that this is a solution -- but it seems reasonable.

Engine is an O-360 swinging a Sensenich 72FM prop. The hinges on the bottom have lost 3 ears each on the cowl side of the hinge. All other hinges are ok. When I was building I was under the assumption that the 6's loose bottom hinges more than the 4's due to the large flat bottom of the cowl catching the pulses from the prop. CS props had more of a tendency than wood props to break hinges. The hinge behind the spinner was also a week point but that has been taken care of on the new S-type cowls with the use of nutplates and screws in this area. The vertical cowl to fuselage hinges have not been much of a problem and the same can be said of the horizontal cowl hinges. Few break. When I finally have to replace the bottom hinges I plan on nutplates and scews. I would stick with the hinges everwhere else as they are effective and low in cost.

Subject: Metal Hinges to Fiberglass
From: Gary Graham <beeb(at)teleport.com>
I ask my dog Pugsley how he would attach the aluminum hinge to fiberglass parts. This is what he said: You know Clem, It would be nice if you told me what kind of resin those fiberglass parts were made from, however, here are some basics. Drill and counter sink for rivet installation as per the plans. Locate the 3/32 rivets next to the hinge segments rather than in-between them. Remove stress risers (sharp corners) and taper segments as required with small files and Emory paper. Use soft rivets not old hard ones. Sand the fiberglass under the hinge to remove high spots and irregularities. Squeeze the rivets if possible by hand power. Do not counter sink the hinge (It is weak soft material. If you must, use a backer strip under the shop head). Do not over counter sink the fiberglass (Make it thicker, if necessary). As for bonding: The reason to bond, is to stabilize the metal/fiberglass interface. This will greatly improve the life of the junction and keep both rivets and hinge from fretting (Vibration and thermal expansion rates). If your fiberglass parts are made from epoxy resin, Do Not Use polyester as a glue (OK for polyester parts sanded to fresh material). Do Not Use fiberglass "Mat" as a filler with epoxy resigns. Mat is random orientation glass strands bonded with corn starch, that will not wet out with epoxy's (It is formulated to work with polyester. You shouldn't need Mat in the airplane but if you do, make sure it's not the stuff that has been available for years, i.e.. a new product for epoxy). My favorite bonding agents in this application are the ones that stay flexible and are great glues. "Proseal" is a real good candidate and you have a can handy. Epoxy's are great glues but it is hard to find formulations that don't cure hard. There are some Methacrylates(sp) that are good glues for dissimilar materials and plastics (again hard to find). Remember we are looking for a good glue that dampens vibrations and thermal expansion problems and is resistant to aircraft type chemicals. If you must use epoxy, the use of the holes to make a plastic button head interlock, is a good idea. Don't for get to rough up those surfaces. Squeeze those rivets before everything gets hard.

(C77) > Thanks Bob, You are correct, there has been many an auto conversion that turned out disappointing - interestingly those are the conversions that seem to be remembered. Matching the right engine with the right airframe is a crucial requirement. If the auto installation weights considerably more than the Lycoming the aircraft is designed for then even if it produces more power the performance is likely to be disappointing. The four rotary powered aircraft at Sun & Fun had installations ranged from being lighter than an 0320 to my own which is about 10 lbs heavier than an a typical 0-360 installation. Attention to detail is critical in keeping the weight down as are design decisions. Just like with Lycomings the aircraft which generally weighs the less performs the best - no different with auto installations. In addition to the Wankle Rotary engine producing the right power/weigh ratio (at least for the RV series airframes), a second important factor in the rotary engines relative success as an aircraft power plant is the fact that there are over a dozen RV projects (at least 8 flying) and we all share information. So by doing this we are able to advance the state of the art by not duplicating each others mistakes and all benefiting from the successful approaches. I expect to see many more than the 7 auto conversions that were at Sun & Fun 2001 in the future. You may be interested in knowing that Sun & Fun 2001 issue a plaque for the "Best Auto Engine" of which I had the honor to receive for my Rotary Powered RV-6A.

Subject: METO fuel configuration
Does the DAR have any experience inspecting RVs or has he been inspecting very light planes. If you have a gravity fuel system the amount of fuel in the tank can effect the amount of fuel flow. In that case you have to verify METO at a minimum fuel level to ensure you won't starve the engine on takeoff. This should not be an issue with duel fuel pumps on an RV.

Subject: sticking bearings
Yesterday I removed and found that the bearing ball from the vernier throttle cable to the carb was stuck tight. I could barely move it with a bolt inside for leverage; not at all with my fingers. This was a good bearing when I installed it about 100 hours ago. Perhaps the heat inside the compartment has an effect on them, (even on the cool side) Another thing for our annual inspection lists. I pulled it because I am changing over to a vernier control on the mixture and replaced the old bracket with Van's newer one which accomodates both controls. Even with a mixture return spring, I still don't trust the single wire control on the mixture. Anyway, as has become the norm, the bracket needs major modifications to fit. The throttle side fits fine, but the mounting hole for the mixture vernier is pointed downwards as if the mixture cable was routed through the firewall from the panel downwards and along the floor. Mine routes above the rudder pedals and through the firewall about 3-4" above the battery box along side the throttle. The bracket is now cut in pieces and will be riveted back together at an appropriate angle. And speaking about rudder pedals, I also just removed mine to comply with Van's AD about welding flanges along the pedal assembly to prevent it from breaking at the joints when you step on them too often or too hard. What a pain in the butt that was, trying to contort myself to reach all the mounting screws and then trying to twist and turn the pedal assembly out of the airplane. I'm not at all looking forward to having to re-install it. By the way, on close inspection there was no sign wear or of imminent failure. My advise to all those still building: Make yourself some kind of large access door so that you can easily get into the area in front of the panel and aft of the firewall. I guarantee, you'll need to get in their a lot more often than you want. Andy ________________________________________________________________________________

Can anyone suggest some reading material where I can find out the proper procedure to install the wheels. The manual wasn't very helpful. I know, shocking considering this is an RV-4. All I have done so far is put the tubes and tires on, slide the wheels on the axles, and screw the nut on finger tight. Should I add any more bearing grease than was already on the bearings? Should I grease the axles? How tight should I torque the axle nuts? Any suggestions, pointers, procedures, etc, would be most welcome. ________________________________________________________________________________

The reason that bracket is angled that way is mostly a result of the geometry of the arm. I don't see changing it much without messing that up. I was the first one to use that bracket but I already had a custom (longer) cable and wanted to route it up higher -- it comes out the top right hand corner of the recess, straight down the firewall then 90+ degrees to the bracket. A pretty sharp angle but I have a decent radius on it so it worked out all right. But I'd probably consider just running it through down low like Vans has it set up for if I were doing it over. In any case I didn't have to modify the bracket. Anyway, good luck with it however you end up doing it!

Hey Bob, For the price go to their site http://www.navaid-devices.com/index.htm . About $1,300.00. After much thinking I installed my Navaid under the right side flooring as indicated in the drawings and photos that they will provide if you ask. I will let others speak to "it's usefulness" I installed a longer push rod ( same diameter thicker wall ) so as to reach across and connect to the left hand control stick. this requires some extra care to get the position of the servo unit just right but it is worth the effort. You can install during wing construction if you want it in the area just outside the bell-crank area ( conventional ) or do it later on in the fuse or at the wing tip. Due to chronic lower back trouble I had my fuselage mounted on an engine stand and tail support of my own designs at the time. If I had to do the install with the aircraft assembled I would install the unit in the wing tip. All three positions seem to work quite well from what I've seen in the archives and on this very helpful rv-list.

Depending on how the airplane being worked on is configured, you could possibly make something "look better" on paper by using that much fuel in the Min Fuel W&B calcs... but it seems to me one would be wise to know what the CG does at considerably lower fuel than almost 2 hours worth... just IMHO.

All of this doesn't make any sense anyway. Only "unuseable" fuel should used for these calculations. You want to have C.G. in allowable range when fuel runs out so you can glide down to a controlled landing, don't you? Get another DAR if he can't see that.

I don't know about the D.A.R.'s concerns, but in my RV-6, the more fuel you burn, the more the CG moves aft. If I fly at maximum takeoff weight with two heavy bubbas on board, I cannot fly down to less than 10 gallons of fuel on board without exceeding the aft CG limit on the airplane.

Subject: Re: Inclination on fuel pump
Kevan, excellent question and example of why your postings are among the ones I always read. Yes, on my Q2 I used to run the tank dry quite often. Over the course of approx. 1050 hr, I probably ran the main tank dry 100 times, and no, I never had a problem with the pumps self priming abilities. To properly understand my answer you should be supplied with an explanation of the fuel system of my particular Q2. The fuel system was composed of two fuel tanks, a 22 gal lower tank and a 6.5 gal header tank above it. Fuel was pumped from the lower tank to the header tank by the same model Facet pump as Van recommends. The pump was mounted horizontally on top of the lower fuel tank, perpendicular to the direction of flight. The pump ran continuously as the header tank incorporated an overflow tube, that returned the excess fuel to the lower tank. When the lower tank ran dry, I would shut the pump off. The lower tank fuel gauge was mechanical similar to a Citabria wing tank, and was fairly accurate. The header tank which had a deep sump, and was well baffled, used a sight tube mounted on the dash, which was extremely accurate. The carb was gravity fed from the header tank. Since the engine burned approx. 3.5 gal per hr in cruise, it was not unusual on short flights to start out with only a couple of gallons in the lower tank, and run it dry. However there are some significant differences between the above system and the standard system in an RV6. The RV6 pump must pull fuel through approx. 75" of 3/8 th tube, a valve and 5 bends. My Q2 system, 16" of 1/4" tube and one bend. But the RV6 system has a significant advantage, the engine driven pump is also pulling. Unless of coarse you have a engine driven pump failure just as you run a tank dry. I had the pump fail twice in the 1000 + hrs both times it was the switching transistor. I replaced the transistor, which used to be surface mounted and easy to replace. Why did the transistors fail? I don't know. Could it have been from the vibration of the pump running dry? Quite possibly as the pumps really rattle when they start to run dry.

Except as provided in paragraph (h) of this part, the nationality and registration marks must be of equal height and on - (1) Fixed-wing aircraft, must be at least 12 inches high, except that: (i) An aircraft displaying marks at least 2 inches high before November 1, 1981 and an aircraft manufactured after November 2, 1981, but before January 1, 1983, may display those marks until the aircraft is repainted or the marks are repainted, restored, or changed; (ii) Marks at least 3 inches high may be displayed on a glider; (iii) Marks at least 3 inches high may be displayed on an aircraft for which an experimental certificate has been issued under 21.191(d) or 21.191(g) for operating as an exhibition aircraft or as an amateur-built aircraft when the maximum cruising speed of the aircraft does not exceed 180 knots CAS; and (iv) Marks may be displayed on an exhibition, antique, or other aircraft in accordance with 45.22. (2) Airships, spherical balloons, and nonspherical balloons, must be at least 3 inches high; and (3) Rotorcraft, must be at least 12 inches high, except that rotorcraft displaying before April 18, 1983, marks required by 45.29(b)(3) in effect on April 17, 1983, and rotorcraft manufactured on or after April 18, 1983, but before December 31, 1983, may display those marks until the aircraft is repainted or the marks are repainted, restored, or changed. (c) Width. Characters must be two-thirds as wide as they are high, except the number "1", which must be one-sixth as wide as it is high, and the letters "M" and "W" which may be as wide as they are high. (d) Thickness. Characters must be formed by solid lines one-sixth as thick as the character is high. (e) Spacing. The space between each character may not be less than one-fourth of the character width. (f) If either one of the surfaces authorized for displaying required marks under 45.25 is large enough for display of marks meeting the size requirements of this section and the other is not, full-size marks shall be placed on the larger surface. If neither surface is large enough for full-size marks, marks as large as practicable shall be displayed on the larger of the two surfaces. If any surface authorized to be marked by 45.27 is not large enough for full-size marks, marks as large as practicable shall be placed on the largest of the authorized surfaces. (g) Uniformity. The marks required by this part for fixed-wing aircraft must have the same height, width, thickness, and spacing on both sides of the aircraft. (h) After March 7, 1988, each operator of an aircraft penetrating an ADIZ or DEWIZ shall display on that aircraft temporary or permanent nationality and registration marks at least 12 inches high. Section iii is for you. Unless you intend to fly a ADIZ or DEWIZ then if your cruising speed is 180 KNOTS CAS you can use the 3". Note! Canada doesn't count.

Here are a couple of things to consider, based upon my experience: 1. check the archives. There have been some in-depth debates on this in the last couple of years. 2. YOU'RE the manufacturer and you specify top speeds, cruise speeds, etc. Don't (necessarily) go by what someone else say's their plane will do. Remember, RV's have a reputation as being a fast plane. Don't let this work unfairly against you without justification. 3. My FAA rep just asked if the plane fell within the speed requirements for 3" letters. I truthfully answered and said I expect that it will. He said OK. 4. As with this METO stuff, it's possible you'll get a DAR or FAA rep who is out in left field. Do your homework and present your case. You may get what you want. 12" letters are kind of like voluntarily allowing a search of your car when stopped for a ticket - unnecessary legal exposure. But go ahead with allowing the search (12" letters!) if you think they're going to take you to jail otherwise.

Mark, Are you talking about the fuel bowl to the housing or the housing to the firewall. For the fuel bowl itself, line up the arrow on the bowl with the front of the upper housing. There is an aligning pine in the upper housing that fits into the top of the fuel bowl lip. Then the locking ring screws onto the fuel bowl. Tighten the locking ring hand tight only. Then you can use safety wire to keep it in place. If you are talking about the housing to the firewall I made a brackett out of angle aluminum that bolts to the top of the housing.

Mark, The bowl has a small pin in the front and another in the back that point up. The locations of each pin is marked with a small circle on the bowl. These are indexing pins. The pins mate with the top part of the gascolator. There is an o-ring around the top of the bowl. Just line up the pins and push the bowl up into the body. The o-ring makes it a tight fit. There is a lock ring with threads that spins freely on the base of the gascolator body. Once the bowl is inserted spin the ring to ingage the threads on the bowl and tighten it up. The spinning lock ring has several holes through it for safety wiring. These are first class units. The feature that is note worthy is where the in and out fittings attach. Once a fitting is tightened, it may point in the wrong direction. No problem, the assembly the fitting screws into will come out and can be rotated and reinstalled to get the fitting pointing in the right direction! I have the fuel selector also, and it is excellent too. Well worth the extra $$.

Subject: Re: Inclination on fuel pump
Garry, While your Q2 experience does give a certain level of comfort, the differences between the Q2 and RV design and operation make it difficult to take full credit for the Q2 service history when considering our aircraft. For example, it seems that you have never ran the pump dry and then immediately had it reprime in the Q2. Even if your fuel system was installed as Van recommended, it would be a good idea to find out what happens when you run a tank dry. I would rather do this test under controlled conditions than to find out the hard way when this happens and you are not expecting it. It might be a good idea to practice some simulated forced landings (i.e. pull the engine to idle and leave it there until touch down). Then once you have confidence that you are 100% current in forced landings, fly around overhead a quiet airport with a reasonably long runway, and run on one tank until the engine quits. Note what warnings you have that the engine is about to quit. Wait a few seconds (to make this test somewhat representative of what would happen in a real event), then do whatever procedure you have established for an engine failure (boost pump ON, change tanks, mixture to RICH, carb heat ON, etc). Note how long it takes for the engine to restart. If your engine has difficulty restarting, you may need to change your emergency procedures, or you may need to change your fuel system design (or maybe you just have a bad component that needs to be changed) to allow it to purge the air better. This is a good test for anyone to do during their test phase. It will help validate that your fuel system design and components are acceptable. It will also help validate your emergency procedures, and it will help you be better prepared for a real event if it ever occurs. It will also give you confidence if you ever have a low fuel situation, and want to deliberately run one tank dry. You'll feel a lot better about doing that if you have done this test.

After following with great interest the thread on pump orientation I decided to e-mail the manufacturer for their advice. FWIW here is their unedited reply: "Harry: It is not essential to have the pump positioned as recommended. The pump will work in most any orientation....the preferred orientation is intended to minimize vapor lock and to assure good priming. Regards Craig S.

Subject: Re: could this be vapor lock?
Follow-up on my suspected vapor lock problem in the RV-6A is now possible, as my first flight since the problem showed up has now been completed. I screwed up my courage today, and, with an aggressive flight profile in mind, climbed out at Vy until 3500 feet AGL while circling home field. I then headed out to Bob Barrows' place for a session with his Hodges Fuel Volatility Tester. I ran on the avgas tank and with the fuel pump on the whole time. The only little problem was one I had experienced a time or two before on turf strips: the engine choked and quit at the end of the roll-out, after trailing clouds of black smoke most of the way down the runway (so Bob tells me; I never saw it.) Seems the carb is set a bit too rich at idle, or maybe the floats are letting too much fuel get by when they are jiggled and bounced around. This rich idle problem may somehow play into the in-flight stumbling I was having on that hot day last weekend; it's difficult to know for sure. I plan to look into it very soon, pull the carb and check the floats, needle and seat, maybe replace the main jet with one that isn't drilled out so much (I took it from a #43 to a #37 drill bit size, in one jump, about 3 years ago. It seems I overshot the correct setting just a bit.) The upshot of the fuel testing is that my winter blend premium mogas has a reading of 7.5, while the 100LL measures 9.5 Both these readings are in the "green arc" of the tester, but the higher numbers mean more vacuum can be pulled in the syringe before the fuel specimen begins to boil. I neglected to note what the units were; probably inches of mercury, vacuum. The test was performed at 1100 feet MSL, which I am sure affects the readings slightly vs. sea-level. Hard to tell if 2 units higher volatility means the mogas was responsible for the engine's coughing as I throttled back in cruise on that unusually warm day April 7th. The carburetor may be somehow to blame. The search continues. Meanwhile, the price of premium auto fuel has climbed so much, 100LL is hardly any more expensive. Good grief! Discussion and advice always welcome - that's why I share this stuff.

The secret for me was to use GOJO on the tire bead so the rim half with the valve stem hole could be pushed down on the tire until seated. I then took the tube out of the box and fitted it between the rim half and inserted into the tire as far back as possible. Lube the other bead of the tire and push the remaining rim half down just far enough to get a turn or two on each of the 3 bolt and nut combinations. Now reach in the rim and with one finger make sure the tube hasn't worked it's way between the two halves and torque each bolt to 90 in.lbs.. Inflate and dance around the hanger! Worked for me!

Date: Apr 20, 2001
Need help on orientation of wiring. Got the Pre wiring harness . Have put relays on firewall run leads all looked great until I found Drawing OP12 Section A-A Top Left Please look at starter and master relay. Shown is P17 going from left hand side of the starter relay to starter. It also shows P16 going from right of starter relay to right of master relay. This is also shown in the photos and plans showing how to set out the firewall to run wire, and in the RVator, Number 1 - 2000. Problem Now look at drawing OP - 10, bottom left hand side and Lightweight starter circuit diagram. This shows the opposite to all the other drawings and photos. e.g: P17 goes from the right hand side of the starter relay to the starter. P16 goes from the right of the master relay to the left of the starter relay. So what is the go? Which is the correct way? Is OP12 and the photos wrong or are they both right.

Eric said: << I mean why would 2 hours fuel put you in jeopardy more than nearly dry << tanks? If 10 gallons would put you in an aft CG condition then wouldn't << full tanks put you in a worse way? Can you explain the reasoning for the << DAR's concern to a simple country boy. Please use one syllable words or << less, if not I'm gonna have to call that damn Pugsley. That dog really << knows his milk bones. As you suggest, if the fuel is not located on the loaded CG of the airplane the amount of fuel will make a difference in where the CG is. If the loaded CG is aft of the fuel, which is the case in my airplane, a light fuel load will aggravate an aft CG situation. I weigh on the bad side of 240... the CG moves waaaay aft when I sit down. :=(( If I sat down in an RV-3 that had a small engine and wood prop, it's possible that the CG would be aft of the aft limit no matter what the fuel load (and I would be writing the list asking how to mount the battery in the spinner...). That's not the case with my airplane, thank goodness. If you find, as I suspect you will, that the CG moves aft with less fuel aboard when nothing else changes, then a light fuel load, large occupants, and lots of baggage behind the seat could be a bad deal IF your airplane tends to have an aft CG when loaded anyway. BTW, who is this Pugsley?? :=)) Randy mentioned: << If I fly at maximum takeoff weight with two heavy << bubbas on board, I cannot fly down to less than 10 gallons of fuel on board << without exceeding the aft CG limit on the airplane. Randy, seriously, I would put something heavy up front, maybe a harmonic balancer (I assume you have a wood prop??) or something. As Finn pointed out, you need to be within the CG envelope at flameout... you and Bubba will be in deep dodo if the fog rolls in and you need to burn below 10 gallons to get to an alternate, etc etc...

Harry, I use the Peltor 7006 headsets. Over the years I've owned various brands of headsets (david clark 13.4's, peltor 7004's.) Recently I bought a pair of Lightspeed QFR passive headsets, but didn't like them because the strain relief on the cord coming out of the earcup would rub on my shoulder harnesses, and if you turned your head quickly they'd come off. Light, but not as comfortable as the Peltors. I bought the 7006's from Chief Aircraft (ask for the web special price of $180.00) about three months ago and love them. They are the most comfortable and quiet headsets I've owned, much more comfortable than the 7004's I have due to the larger earcups. Dave Clarks are like strapping a boat anchor to your head compared to the Peltors IMO. A friend of mine who has Lightspeed 25XL ANR headsets flew with me not too long ago and he said that they were more comfortable than his Lightspeeds, and came close to being as quiet.

A lot of avionics retailers won't quote (over the counter) prices on installed only products (garmin, s-tec) because of manufacturer policies. However, some experimental friendly retailers will sell you whatever you want. I've ordered all my goodies (s-tec 30, gns-430, sl70, gtx-327, nav122, bootstrap gyros, etc) from john start avionics. Seems like a great guy and gets stuff out on time. Some have had him prewire some harnesses for a reasonable fee. He'll usually tell you what the stuff actually costs then figure in his standard markup. 5-10 % for listers. I only recommend him because of how happy I was with my dealing with him.

Chuck, Ray, and other variations of -4 drivers, Here is the the input of a -9 builder: It was seeing a pristine RV-4 sitting on the ramp that made me fall in love with the RV series in the first place. I too think that a modern pre-punched version would be a good idea.

Chuck, Ray, and other variations of -4 drivers, Here is the the input of a -9 builder: It was seeing a pristine RV-4 sitting on the ramp that made me fall in love with the RV series in the first place. I too think that a modern pre-punched version would be a good idea. I chose the -9 for a variety of reasons, but the biggest one was path of least resistance, ease of building and quicker to get in the air. But I still think the -4 is the prettiest. Just my opinion.

Rick, the 327 will display the altitude that the encoder is transmitting so it can interface with digital output from a gns-gps or from serial data direct from an encoder. Ii don't know that the 320 does this... Steve In a message dated 4/20/01 8:48:03 AM Eastern Daylight Time, rickjory(at)email.msn.com writes: I agree with Rick based on recent shopping. However, I was told by the vendors and Garmin at SNF that they can not sell the GTX 327 transponder for me to install myself. Can somebody confirm that this is not true? They would sell me the GTX 320. Was also told by Garmin that the inner workings of the 327 and 320 are now the same. Only the front panel is different.

Give Southeast Aerospace a try. I bought a KT-76A transponder from them including the install kit, rack, and manual and paid $1050. That was on 9/17/99.
