Got a electronically chaleged question. The pitot blade (Piper Type) has two wires, there is "P" stamp next to one and a "S" stamped to the other. My guess was P stood for wire to pressure and S stood for the wire static for heating. Does that make sense to the electrons? Denny H.

Subject: Powersport-Mazda Update
Our Friday message created some confusion regarding horsepower. In that message we noted we had used nitrous for the climb competition at Sun'N Fun and also that we were generating 200 h.p. Here is clarification: our engines are rated at 200 h.p. without nitrous. With nitrous and increased r.p.m. we generate 350 h.p. This is what made the RV-3 especially potent in the climb competition before we toasted the aft propeller shaft bearing at the completion of the cross-country race where Alan Tolle placed first in class in his RV-3 and fifth overall. On this prototype unit we will retain a plain bearing with some related modifications. Even before Sun'N Fun we had already incorporated numerous design refinements into the reduction gear assembly for subsequent units. Amoung these was replacing this plain bearing with a ball bearing. The base engine continues to do very well and we are exceptionally pleased with the service of the various modifications, fuel injection, dual electronic ignition, etc. A word of caution here folks regarding the use of nitrous on our engines. We do not have alot of experience yet with this so it remains very experimental and anybody considering it should proceed with measured caution. Additionally, putting 350 h.p. through a two-balde wood propeller made it go through some very strange contortions during testing prior to the time-to-climb race. Hope this proves helpful.

Subject: AOA Measurement
I've come across a relatively inexpensive angle-of-attack device (RiteAngle, about $200). It requires the mounting of a small vane (2"x2.5") in a location where there is a reliable, repeatable difference in the airflow over the vane itself and the wing's actual AOA (best situation would be pure relative wind, but the unit has adjustments to compensate). Wingtip and L.E. boom locations have already been suggested, but I don't like those due to aesthetics and damage vulnerability, etc. I am thinking about a location under the wing somewhere around the pitot tube. Anybody know how far below the wing you would have to go to get some relative wind?

Subject: One year down the track... Reflections.
Hi Guys, Well, it's a year since I received my empennage kit, so I thought I'd take a moment to reflect: 1. During that year, I spent 350 hours building. A *lot* less than my planned 1000 hours. In more recent months, my building hours are up to round 50-60, which seems about the limit of what's sustainable long-term for me. Based on this, it looks like my plane's about a 5-year project. 2. I now have a pile of quite aeroplane-like items; all the empennage except the right elevator, and some wing spars. Looking at these, I optimistically feel like I have a fifth of a plane; realistically I guess that an eighth is probably about right. 3. I've spent in the region of US$5400 plus NZ$1500. Most of the US$ was on the emp and wing kits (US$1095+US$3700), and a fair proportion of the rest went on tools which I get to keep, but there's a heap of freight & tax which is just lost money. 4. I started off fairly uncertain whether I was sufficiently motivated to do a long-term project like this. I really wanted a plane, rather than to build one. That's changed a bit; now I enjoy workshop time for it's own sake rather than having to focus on the final product. 5. I've developed a lot of skills; I didn't realise how much until I helped teach someone a few basic rivetting skills. Actually, the teaching was quite difficult because lots of those skills have been unconscious habits, like clamping things tightly together for drilling, and deburring parts. 6. I've gained a lot of confidence in using tools, putting things together, figuring out things from plans, etc. 7. I've met many wonderful people, both in person and on the Net; I think that homebuilders are perhaps the best bunch in the world! I couldn't have done it without you guys... thanks. 8. I'm starting to think about what to build after the RV-6! Frank.... 1 year down, only 4 to go! ________________________________________________________________________________

I was not thrilled by the elevator control rod bolt being the "torque rod", if you will, carrying all the connective responsibility of the two horns: not only does it push and pull the elevators it also takes the shear stress of any difference in pressure/load between the two elevators. SOOOoooo.....after installation of the elevators on the fuselage, I made up a small block to fit between the two horns and ran two AN-3 bolts through. Now, the bolt from the control rod only carries the push/pull loads while the two horns are bolted together, functioning as a single unit. Just something else to think about..........

Hi all, At Sun N Fun I fell in love with the fuel caps that ACS is selling. I forgot who the manufacturer is but to say the least they are works of art. They lock, and the mechanism is as smooth as silk as it opens. As I have not yet built my tanks I would like to replace Van's standard caps with these. The only place I want to pour fuel is in the tank, not on o-rings. Has anyone installed these in a prepunched kit? These caps come in 10 hole configuration but who knows if they will line up. If not, is it possible to weld the holes shut then drill new ones. Or, in the opinions of those that have gone before me, would it be acceptable to just fill the holes with pro seal and then rotate the flange and drill new holes.

As you have stated in your latest post, there are four wires on your pitot tube. In that case, two wires are for the pitot, ram air heating, and two are for the static air port. Also, as you mentioned, one must check to see if any of the wires are grounded internally, if they are, the grounded wires must be on the negative lead. One might also check to see if there is resistance with an ohm meter across the heater elements. This is to varify that there is indeed good heater elements in the unit.

I did so thinking that it would be good to protect it, but have since found out that: - Finish paint systems depend partially on "chemical bond", which goes away if the primer has cured beyond a certain length of time - If you have a paint shop paint your plane, they may not be willing to guarantee their work if it's going over some "unknown" primer that someone else put on, and may just want to strip it off anyway - You'll be a lot more likely to be able to get any contaminants cleaned off of bare aluminum than from primered surfaces Randall Henderson, RV-6 randall(at)edt.com http://www.edt.com/homewing ________________________________________________________________________________

I just talked to Rick Bauerman, who is an applications engineer at Hartzell. He confirmed that the M2YR-1BF/7666A-2 prop is only rated for up to 3.8 Gs. Since that is the prop Steve Barnard builds his really neat IO360 cowl around, and I am not interested in fiberglass work enough to build my own cowl for the IO360, I'm afraid I'll have to stick to the parallel valve 360 and the C2YK prop Van's supplies. While I don't intend to do extensive aerobatics, it doesn't seem sensible to me to build a 6 G sportplane and then put a 3.8 G prop on it. I'm sure others who want their RV to be a cross-country rocket will enjoy the better aerodymanics of Steve's cowl and longer prop. Rats! Oh well, at least I found out before I spent the big bucks for an IO360.

They are basically a threaded tube that compresses into a hole and grips on the blind side. There are a couple of different methods of installing. The simplest is ...you guessed it...a rivnut putter inner tool. Its like a popo rivet gun. Quite expensive but you may be able to borrow one. The second is by using a special mandrell and an allen key...this may be available from A/c Spruce. You may also consider not using an Adell clamp if the bundle is not too big. There are some small plastic clips that can be pop rivetted and then a plastic tie wrap threaded through to hold the wires. An electrical shop should have these. They are light and very inexpensive.

Try Rivnuts. Available from ACS, they are installed blind. Also if you're securing wire, there are tywrap hold downs that have a 5/32 hole, and work great with 5.32 pop rivets. Is you are securing wires near flight controls use Adel clamps though. Tywraps may break over time and then the wires may get into the controls.

As for the last question, I wouldn't recommend you doing 'prolonged' inverted flight unless you do have the flops etc. So, anything with zero or negative g for a period of time that will cause either fuel or oil starvation is not desirable unless you don't mind engine stoppage due to no fuel or no lube.

Fellow listers, I need the collective knowledge of the list to help me solve an annoying problem with my RV-6. Since the first flight 10 days ago I am getting a very loud noise in the cabin that starts at 120 knots IAS. Since the first flight I have installed the wheel pants and gear leg fairings. I have taped over the intersection where the future cuffs will go. I have taped over scat hose inlets one at a time. All other fairings are tight. This noise is strictly airspeed related. It sounds like a bad bearing in an electric motor or a reed vibrating. It is so loud that it breaks the squelch on the intercom. The noise is deafening with headsets off. I have gone to 170 kts and the noise stays with me. If I make sudden pitch changes the noise will change note or go away momentarily until relative wind resumes normal angle. I do have 2 bent whip comm antennas on the belly. I am going to try to stick a small bead or ball on the end to change the harmonics. They may be vibrating. Other than that I am stumped. I will entertain any other ideas. Terry C-GZRV flying ________________________________________________________________________________

Subject: aileron/flap fitting
Hi all, After a trial fit of my flap and aileron to my wing still in the jig, I have noticed a problem. Sighting along the trailing edge of the wing there is a noticeable bow spanwise. Drawing a taught string along the top of the two surfaces at the start of the trailing edge bend confirms that there is a gap between the string and the flap/aileron top skin of about 1/16 inch. My initial thought was that I had somehow built either the flap or aileron with a slight twist. I rechecked these and confirmed that they were both straight. I then drew my string across the top surface of the wing about 1 inch behind the rear spar rivet line and of course found this was also bowed. How I got to this point without seeing the bow during construction, I dont know. The bow is not obvious when sighting along the top of the wing when the control surfaces are not attached. Is this bow going to cause a problem for me or is it something that I will be able to trim out in flight, so that it is only an aesthetic problem? At this point my top skins are rivetted on but bottom skins are still clecoed in place. Can I or should I attempt to fix this by pulling the rear spar straight when I rivet on my bottom skins? I visually checked the 3 RV's at the local airport and 2 of them appeared to have bows one way or the other when sighting down the wing trailing edges. I was unable to talk to the owners to see if they noticed any controllability problems due to this. It is also possible that these airplanes had twisted or misaligned surfaces rather than a bow in the wing.

Date: May 07, 1997
I searched the archive last night for ways people have sealed the access plate and sending unit on the fuel tank. People have used cork or rubber gaskets, fuel-lube or pro-seal. I used fuel-lube on the stock cork gasket a few days ago during leak testing and was thinking of changing to the pro-seal route for peace of mind. I've ridden in a RV-6 with leaking fuel tanks and it make the flight less than pleasant in the cockpit. So I'm hoping to get these tanks sealed for good and never have to open them again. Okay, so what's my point? When I removed the sender and access plate from the fuel tank after leak testing (the next day) I was suprised how "sticky" the fuel lube was and I felt better about just using the cork gasket and fuel-lube. Are there many people out there who have been flying RV's with this setup and having no fuel tank leaks? I'll probably put a dab of pro-seal in each screw hole anyway to make sure those don't leak.

Hmmmm. I can't see why you would have ELBOW problems. I expected hand problems, but I've built up quite strong hands as a guitarist; ditto the wrists due to keyboard use for 13+ years. In fact, clecoeing (is it Ok to use clecoe as a verb?) is often a restful time for me. I get most fatigued when drilling the vertical skins, especially on the higher reaches, due to holding up the drill motor. Ok, so I'm not a weight lifter. Are you possibly having to twist the clecoes out of the holes because you are not compressing them completely? That's the only elbow stress I could come up with as I self-consciously removed and replaced clecoes (and now Judi is laughing hysterically at me, thank you very much). I'd be interested if others have experienced problems.

Fellow Listers: A quick electrical question. As I work on my RV-4, I am also restoring a Citabria. I am adding Mitchell electric oil temp and pressure gauge. Mitchell states these each pull .8 amps. I would prefer to protect both these gauges with one CB or in-line fuse. Is there not a rule of thumb to determine CB size for a particular load?

Treatment was basically rest, and keeping the arm supported and elevated (wrist at about chest level). As I recall, recovery took a week or so. The movement is I think similar to clecoing. Also, I've modified my cleco pliers a little; I ground a little out of the jaws, so that clecos go in and out easier... I can easily shake a cleco out, which allows for one-handed un-clecoing. Also, I added a light spring stretched from the top jaw to the opposite handle, so that the pliers open by themselves. I believe that this makes clecoing much easier.

John, I may not have been clear in describing the bow in my wing. The difference in length rib - to - rib would result in a chordwise bow, but I wouldnt be overly concerned about this. If you picture the airplane flying straight and level, then the bow in my wing would be in a direction perpendicular to the ground. The effect of this would be a continual change in incidence across the span of the wing. In thinking about this in this way, I believe the error is probably insignificant as it is a change of 1/16" over the chord of the wing, or less than .2 degrees of incidence. It is however, somewhat discouraging to sight down the trailing edge and be able to see this deviation. Mike Wills RV-4(wings) willsm(at)manta.nosc.mil My ribs vary by as much as 1/4".

At one point, I experimented with putting sellotape on filters to make nice fuzzy halo effects (for romantic wedding photos). I was amazed at how small a circle I needed; less than an inch in diameter. If you have a large-format camera you want to mount, I guess you'd need a larger hole. Or is the idea that you look round the camera to get a general view of the ground? If so, it's going to be a tad difficult to look through that hole whilst flying, and probably even more difficult for the passenger to see through it.

You can run RG-58 to the outboard rib terminating with a crimp type BNC female bulkhead connector. Use any old 30"-31" length of wire draped into the fiberglass wing tip connected to the center of a BNC male connector. Then, a little soft music and... mate them. As an alternative without the sex (or the soft music), just run RG-58 out to the wing tip and strip the last 30" or so of the jacket and shield off (leaving just the insulated center conductor). You might cover the cut end to eliminate the possibility that it might short out against any exposed grounded metal. -GV ________________________________________________________________________________

RV-6 Please excuse my ignorance on such stuff, but it was a none coated(no flux on it), sort of brown looking metal, not quite as large diam. as the coat hanger, not brass. It was some a guy had given to me to bend ends in it to make hangers for painted stuff. I don't know why the coat hanger did not take solder, maybe I didn't get it hot enough. If the Radio Shack ant is stainless steel, that keeps it from taking normal solder, doesn't it? I guess just about any diam. wire that is stiff enough to 'keep it up' in the wing tip would do it, as long as it will keep contact with the bulkhead mount. Mine is curved outboard of the fitting, so that the wire is compressed about one inch at the tip when the fiberglass tip is installed. In my shade tree planing, this would wedge the wire into the inside of the corner where the top of the tip folds into the bottom of the tip, there by keeping the wire from vibrating and bouncing up and down, straining the solder joint at the bulkhead fitting.

I am assuming a 2 amp breaker would be >adequate for this application (total of 1.6 amp load). There's a popular mis-conception floating around suggesting that breakers protect gizmos while in fact, a breaker or fuse has the task of protecting only the wire which branches off the distribution bus. The smallest practical wire for airframe installations is 22AWG. Per the wire table I published earlier this week, a 22AWG is good for 5amps in free air . . . (OOPS, just checked the table and found I'd left out a couple of values. Here's the table with the two missing numbers) AWG Ohms/ 35C Rise 10C Rise Max Path No. KFeet Amps Amps for .7 volt Loss at 35C rating. 2 .156 100 54 45 Ft 4 .249 72 40 39 Ft 6 .395 54 30 32 Ft 8 .628 40 20 27 Ft 10 .999 30 15 23 Ft 12 1.59 20 12.5 22 Ft 14 2.53 15 10 18 Ft 16 4.01 12.5 7 14 Ft 18 6.39 10 5 11 Ft 20 10.2 7 4 10 Ft 22 16.1 5 3 8 Ft So our 22AWG wire is good for 3 amps burried in a wire bundle. In the suituation where we intend to drive 1.6 amps of hardware, 22AWG is adequate in any installation scenario. Further, since the CONTINUOUS load is not over 3 amps, we could burry the wire in a bundle and still PROTECT it with a 5 amp breaker since any expected overload would most likely be a hard fault. There's no need to de-rate the wire for protection purposes because the continuous duty load is so small. In answer to the writer's question, any breaker from 2 to 5 amps is okay in this situation. I'm a little suspicious of the .8 amp figures for power to operate those instruments; here's why. .8 amps times 14 volts is over 11 watts. Since there's no ENERGY coming out of this system other that to wiggle some pointers on an insturment, ALL of this power comes off as heat. Which gizmos in each system disipate all or any part of this much energy? Certainly not the instruments . . . anything more than about 2-3 watts inside a plastic case would COOK the innards. How about the transducers? Hmmmm . . . I suppose they COULD stand that kind of dissipation, they're designed to function in a warm environment. But when the rest of the world routinely produces sensors that operate with tens of milliamps, I'm having trouble visualizing how the thing would be build to consume 10 times that amount of power. I'd recommend rechecking the literature -or- contacting the manufacturer -or- hooking them up on the bench with a power supply and see what the real numbers are. I SUSPECT they are considerably less. This doesn't change the breaker sizing task but it does afford more confidence in the system's ability to survive . . . 11 watts is alot of snort to handle in a task that's been seeing smaller and smaller power requirements through the evolution of new designs.

It provides a much harder finish and seems to spray well. The paint expert at the automotive paint supplier didn't have much trouble figuring out that I was an amateur and steered me away from variprime toward DP-40. It is my impression that the DP-40 is high quality and less toxic than variprime. I don't believe it's a self etching primer, so scuff or etch. I bought a $30.00 8oz. amateur touch-up gun that sprays it very nicely. I beleive that going this way has an added benefit. I'm getting to be a better painter in preparation for the big job ahead.

Just to reinforce something that has been mentioned here before, the method should use Ground Tracks from the GPS, not headings.

Date: May 08, 1997
I am posting this for a friend who recently purchased an RV6A but does not have access to the RV-list .... yet. >>>> I seek the wisdom of the RV-List in solving a dangerous (in my opinion) problem. <<<<< Problem: Loss of fuel pressure, engine sputter and HIGH pucker factor on takeoff . The plane was airborne and he (+ another friend passenger) landed safely. He had flown it earlier and stopped for a few minutes, so it was still "warm" under the cowl. Setup: - RV6A with Lycoming 0-320 (150 HP) engine, carbureted ... nothing too "unique" under the cowl. - Fuel in use: AUTOGAS. - Fuel from the selector is routed to the gascolator and from there to the carburetor and to a primer (via a tee). These lines are wrapped in insulating "hose". At the carburetor, there is a small return line to inside the cockpit **just after** the output of the fuel selector. There is a "restrainer" in the orafice of about .040" feeding this small copper return line. Theories: Vapor lock due to: 1. Orafice was too small (seemed clogged, so we opened it to .040") and therefore there was virtually no return. 2. Exposed (small) copper return line in REALLY a heat exchanger and instantly vaporizes any fuel that is in it unless the plane is flying, so maybe it should be insulated. 3. The small line under the cowl should be LARGE so it can hold (relatively) lots of fuel so as to never allow vaporization (its hard to boil the ocean). 4. The small line under the cowl should be as small and short as possible because you want to boil as little fuel as possible. 5. The small line inside the cockpit should be LARGE to facilitate expansion and quicker cooling. 6. The small line inside the cockpit should be longer and coiled to facilitate greater cooling. .... As you can see, theories abound. Before we do something and attempt to fly this machine again, it really would be nice to take advantage of the collected wisdom here. Sooooooo.. Has anyone out there SOLVED a similar problem *without* removal of the gascolator and switching to AVGAS?? I know there has been much discussion about whether or not to have gascolators. For this round of discussion, let's assume that my friend really wants to keep the gascolator for the reasons stated in the list by those that are happy with them. Any assistance here would be appreciated as I thought I was about to witness two friends have an unfortunate landing in trees and railroad tracks ... not a happy thing.

Seems the noise started at about 160 mph. The problem took a long time to solve. Evidently the builder had attached a fiberglass strip over the canopy joint at the rear window junction. The fiberglass had worked loose where it was bonded to the canopy. It was basically fluttering in flight when he got to 160 mph. It was rebonded and the problem went away. Check any parts on or near your canopy. Also check to make sure your root fairings with the rubber trim are tight against your fuselage. You may be getting what we call in the airline industry as "fillet buzz". The metal wing root fairings will start to vibrate on the sides of the fuselage. Well good luck. I suggest not going too fast until you solve the problem.

Subject: spar attach
I got the wings on, ready to drill the rear spar attach points. (RV-4) With the rear spar on wing lined up perfectly with spar carry through (vertically) it came out to 1 deg incidence, as close as I can tell. If I move the wing up approximately 1/4 inch to meet the 1/2 deg. + incidence, the 5/16 hole I will drill will not have the required 5/8" edge clearance. My question is this: If I leave it centered and drill it so there is no question about the edge tolerance, can I adjust the extra 1/2 deg. of positive incidence out with the tail? If I leave it 1 deg. positive, like it is, how will that affect the flying characteristics? Is it something that will need to be adjusted? Thanks for any help, I am going to drill them tomorrow. Also, measuring from wingtip to common point on fuselage, one wing is 3/8" farther than the other. I don't know what that equates to in degrees of sweep, but does one of you experts out there know if this is something to be concerned about? Boy, an 1/8" out, here or there really adds up when you need to measure for something like this. ________________________________________________________________________________

But it seems we don't have all the information. Any extended hub propeller Hartzell supplies with the exception of the HC-C2YK is limited to 3.8 g's. Hartzell says even if you add 1 inch extension to a propeller it goes from a 6 g propeller to a 3.8 g propeller no matter what the extension is all the way up to 6 inch extensions. The propeller withstanding these loads is not the issue, it will not fail, the failure will occur in the crankshaft flange at or near the forward thrust bearing. The 200 hp engine in this area has twice the wall thickness that the 180 hp engine. So here lies the confusion. I would feel better about doing aerobatics in my 2 9/16" extended hub prop and a 200 hp engine than a 180 with half the wall thickness and a standard hub. It appears Hartzell has a blanket policy that they've established yet to my engineering background seems a little contradictory. I understand the gyroscopic loads somewhat on the engine. Maybe someone else at Hartzell can help clarify this confusing policy they have. It's possible it's just that they have'nt tested other combinations at this particular time.

Date: May 08, 1997
With all this talk about alternate antennas, I felt I just had to contribute some thoughts that might save someone's transceiver output section. There is no reason that the aviation antennas should cost what they do. However, if you are looking for affordable alternatives, you might take a trip to your local HAM radio shop. There is an amateur band known as 2 meters that is very close to our band. It operates on 140 to 148 mhz. Most of the antennas intended for two meter use will easily tune down to the 125mhz average that we require. Some have adjustable shafts while others have a tuneable coil in the base. If you are building or installing anything other than an off the shelf antenna, I would buy or borrow an SWR/RF meter. Again, one intented for 2 meters will work fine on aviation band. Concerning lengths... they are simply estimates. Once the coax is run, secured and connected at both ends, the standing wave ratio should be checked. If needed, the antenna can be trimmed to acheive the lowest ratio. If you trim too much and the antenna can not be re-fabricated (if it's glassed into a wing tip for example), a load will have to be added to bring the ratio back down-start with a single turn of wire around a piece of 1/2" wooden dowel, connect in series. Use heat shrink to protect the load after the number of turns have been established, mount away from metal and as close to the antenna as possible. A ground plane must exist or be simulated. Follow your antenna plans closely or your antenna will have unwanted directional qualities. What will I use? Two lengths of 1/2" wide copper braid, laminated into the wing tips.

This cowling is state of the art in the airplane world. That's why we enjoy custom built aircraft so much, because we can put what we want on the airplane. This cowling utilizes seperate CNC machined aluminum laminar flow inlet rings for consistent flow. To date this is the best way to get airflow in the cowling. Modern day jet liners utilize the same theory. If this perks your interest-read on. The following is a detailed description of requirements for utilizing the B.A.C. "Holy cowl" which enables you to install 160,180 and 200 hp engines in an RV-6 or RV-6A. 160 hp engines can utilize a wood propeller with a 4 3/4" spool extension or Van's HC-F2YL-1F/7663-4 constant speed propeller. 180 hp engines can utilize a wood propeller with a 4 3/4" spool extension or a Lancair 360 constant speed propeller #HC-F2YR-1F/F7068-2 200 hp engines must be of the counterweighted versions ala: IO-360 A1B6,A3B6D,C1E6, C1C6 etc. Propeller requirements are a Hartzell constant speed propeller #HC-M2YR-1BF/7666A-2 extended hub propeller or you can utilize a wooden propeller with a 4 3/4" spool extension.

Subject: RV "Wing tips"
The following information is about different wing tip designs, what works and what is available for RV series airplanes. I'm not sure how much has been discussed in this area to date, but I think now is the time to go over it again because I have been personally involved in making the curved up wing tips which many have seen in Sport Aviation April issue. It's begins on page 50,"Computational Fluid Dynamics". I am presently flying with these prototype wing tips and here are the real results. It increased speeds by 2 mph. It increased directional stability in turbulence considerably. Anyone know what it's like to ride in the back seat of a V-tail Bonanza on a rough day. The RV has a tail wag or more appropriately a dutch roll and yaw when the thermals abound, especially in Texas and Arizona on a hot afternoon. These particular curved up tips solve the wag and make it very stable in that arena. This added stability does not affect roll rate. The airplane simply bounces up and down but does not twist and turn anymore. There has been another wing tip come out of Bakersfield,CA. Not sure who is selling them exactly. I ran the flight test on John Harmons "Rocket" because he had a set installed. We ran 2 tests with different wingtips under the same conditions as we could get. Now keep in mind the Rocket wing span has been reduced to 21 ft. 10 in and the top speed it is capable of is much higher than a standard RV. Any additional wing span on the Rocket will help top speed at higher altitudes. The test was run at 8500 ft. density altitude. During lunch after the flight I crunched all the numbers. With many distractions due to the fact that there were probably 10 people wanting an answer on the wing tips and how well they did, I came up with approximately 7.5 mph increase in speed. I later went home and redid all the calculations and confirmed without a doubt 6 mph increase. After several more wing tips of this type we're installed on an RV-6 and a RV-4 and flight testing airplanes against each other we all came to the conclusion without a doubt on the above airplanes we obtained 2 mph increase. The difference compared to the "Rocket" is additional span would help it more, especially when the air gets thin. It doesn't appear the Bakersfield tips add much for stability, but it does help speed slightly. They are available. The wing tips that we're designed using the computer that are on my airplane are not available for certain reasons. Knowing what we've learned from a stock wing tip to the curved wing tip to the rounded tip is, the best tip for the RV has yet to arrive. It will probably be a combination of curved up tip with slight rounded leading edge with a slight increase in span. Not on the drawing board yet.

If the appliance is a transmitter, measure the draw while transmitting. If the appliance is a lamp, measure the draw after it has stabilized at temperature. If it is a motor, put a sustained typical load on it. Then determine the required wire gauge based on wire point to point length assuming a half to a volt drop from the supply to the appliance by using the curves shown in AC 43.13-1A (I think). I got my copy out of a buddy's Glasair Builder's Manual. You must calculate for the voltage drop and the conductor heat rise and select the wire gauge that meets both criteria. If you absolutely cannot otherwise locate this info on your own, e-mail me direct and I will get a copy to you. Select the breaker based on 135-165% (or the next available size up) of the continuous maximum current for the appliance.

Ever wondered ???????? How to get an RV6A to the airport ? How you can fit a built RV6A in a two car garage ? If 3 kids could build an RV6A with some help from their dad ? What an RV builder looks like right after his first flight ? Point your browser to: http://www.mcs.net/~rvgasj/rv6a.html I would like any comments you may have on this web site, I am teaching my 16 year old how to build a web site. This is his first attempt.

James, With the vapor return line feeding back into the fuel source "just after" the fuel selector, aren't you just pumping the vaporized fuel right back into the fuel source? Why not dump it back into a tank and eliminate any possibility of vapors in the source line (due to returning vapors).......

Subject: Breaker sizing
<< In Bob Nuckolls' book he talks about using the actual voltage rating of the << device in question to determine the allowable voltage drop. Is this procedure << not acceptable? This procedure would allow a much larger voltage drop than .7 << volts. For example a system might be putting out 14.6 volts while a lamp was << rated for 13 volts. This would seem to allow a 1.6 volt drop. The issue I was speaking to there was a special case wherein I cited examples of landing lights characterized for operation at 13.0 volts. Obviously, for a system that runs nominally 13.8 to 14.2 volts, the lamp would be quite happy with a drop of .8 to 1.2 volts in the system's wiring. This figure falls nicely into the 5% allowable system losses figure I cited in my earlier posts. The voltage RATINGS of various devices are NOT requirments but simply notification to the system designer as to how the device was characterized . . . so many lumins over so much pattern at 13.0 volts. Since 13.0 was the design point, this tells a designer what to expect in the way of performance under nominal system drops. /Using a good digital voltmeter (or the manufacturer's specifications /if available), determine what the appliance draws sustained worst /case under load. If the appliance is a transmitter, measure the draw /while transmitting. If the appliance is a lamp, measure the draw after /it has stabilized at temperature. If it is a motor, put a sustained typical /load on it. Good advice . . /Then determine the required wire gauge based on wire point to point length /assuming a half to a volt drop from the supply to the appliance by using /the curves shown in AC 43.13-1A (I think). I got my copy out of a buddy's /Glasair Builder's Manual. Also wire table I've published in the past few days. . . /Select the breaker based on 135-165% (or the next available size up) of /the continuous maximum current for the appliance. Actually, breakers are selected according to wire size but maybe that's splitting hairs. Picking the breaker according to applicance load is okay too, especially if you've upsized a wire for voltage drop considerations and left the breaker sized for the load, the trend is to protect bigger wires with smaller breakers which is not a hazazrd. /You do not want to chose too low or you will experience nuisance /trips. We are really trying to protect the wiring, not the appliance. Exactly!!!! Tens of thousands of Cessnas have 60 amp breakers protecting their 60 amp alternator b-lead feeds . . . this breaker is DESIGNED to nuisance trip. I complained about it when I worked there 30 years ago but nobody cared. Now, that breaker causes more unhappy electrical surprises for pilots than any other breaker installation in history. When in doubt, upsize the wire and breaker a step. It never hurts to make it a tad bigger! Regards, Bob . . .

These are non counterweighted engines. Yes some people we're and are still using extended hub propellers. Lance Neibauer of Lancair fame got together with Hartzell after the incident and requested some vibration and stress tests be run with the 0-360 engines and the earlier version of the "F" hub propeller. Before the test this combination had never been tested or approved for certified aircraft. The results were conclusive. The propeller was 200 % over standard stress levels so Hartzell redesigned the propeller to it's present configuration which is an approved combination for the 0-360 non counterweighted engine.

Jerry Prado taught me a bit about antennas - he even knows about SWR. Now I at least know what the letters stand for and that it is related mysteriously to the length of the antenna and the frequency being picked up. He says that he will use "Two lengths of 1/2" wide copper braid...". Come on Jerry, tell us what lengths! And details like their relative placement. We do all use the same frequencies so won't we all want the same length antennas? Is it possible that antennas are like wine - that there is usually a difference in quality between the cheapest and the more expensive? It is true that an inexperienced wine consumer may not be able to taste that difference. I do love these things that puncture the balloons of the people who are ripping off us junior birdmen!

Subject: Re: Advice needed on cutting skin for camera hole
RE CAMERA HOLE CUTOUT I tried this idea on a Continental powered C-172 (two exhaust pipes) many years ago and learned the following, we had to do a severe sideslip to get the engine exhaust away from the camera port. Before cutting any holes have a good look at where the hole is in relation to the engine exhaust stream. Heat from the exhaust stream will distort the light waves and render a improperly placed camera port useless. I am guessing that the exhaust flow from exhaust pipe(s) normally expands about twenty/thirty degrees as it moves rearward and rotates slightly with the propwash, it may pass under the passenger seat area. When I get to my wings I plan to look into the feasability of a camera port in the outboard wing bay and/or a quick change wingtip that will accomodate my motor drive Nikon. Has anyone out there mounted a motor drive camera on a RV? George McNutt, HS - 6A ________________________________________________________________________________

Also, If I dimple the E-616PP cover plate with dies for #6 screws, and likewise dimple the screw holes in the E-615PP, then the nutplates won't fit flush.

The HC-C2YK propellers (no extension) are used on "hard aerobatic airplanes". Pitts Specials and the like. There is no "G" limitation on these propellers. On occasion they do break. Hard aerobatics includes snap rolls and spins which place the most load on the propeller and crankshaft at the thrust bearing. Since Van's does not recommend doing either snap rolls or spins this shouldn't cause a problem. Snap rolls are also hard on control surfaces. Hartzell only tests airplane that utilize the short hub for hard aerobatics. The M2YR hub propeller was installed on normal category airplanes which are classified by Federal Aviation Regulations as a 3.8 g airplane. Utility category is 4.4 g's. Full aerobatic is 6 g's. Obviously Hartzell can not test an extended hub propeller if the airplane is the limit. So they test to the limit of the airplane category. Therefore if the M2YR hub is used on an IO-360 with the heavy crankshaft, mild aerobatics should not be a problem. Keep in mind this airplane is for sport aerobatics. If someone wants to do aerobatics get some quality instruction before attempting anything aerobatic. We've put way too much effort into building these things to throw it all away on a simple roll and split S out the bottom with no altitude left. If some wants to do hard aerobatics try a Pitts Special or Extra. The B.A.C. "Holy cowl" was designed around an extended hub propeller for better aerodynamics due to the longer nose. It also adds length to the cooling inlets before the air gets to the plenum for better ram recovery. I.E., much better cooling. This also enabled a longer intake box for better ram recovery on induction air. Most factory airplanes have a loss of 2 to 3 inches of manifold pressure due to poorly designed airboxes. We have obtained 1" over ambient at cruise settings. What this equates to is better power at all flight conditions. All this with ram-filtered air. We are filtering air 100% of the time. I think the 200 hp fuel injected Lycoming with 1 electronic ignition combined with the new cowling and cooling plenum to be the most efficient & economical as far a speed and fuel burn are concerned that one can put in an RV-series plane. I'm sure I'll pick up some flak on that one. If your looking to improve on a great airplane this is one way to do it. If you want good looks, speed and efficiency or just want something different on your RV this may be what your looking for.

It comes complete including propeller gear reduction, fuel injection, dual electronic ignition etc. Price is $14,900. Cowlings and engine mounts will be available beginning with the RV-3 and RV-4. These cowlings will be >patterned after the "King-Air" type cowling we now have on our RV-4 test mule. Our address: Powersport, 12294 Hatch Lane, Aumsville, OR 97325.

What airframe mods are necessary for that much power? I could see beefing up the forward fuselage and firewall, thicker skins on the tail surfaces and balancing the tail surfaces. Thanks. Cheryl: Regarding your RV-3 questions suggest you talk with Alan Tolle or Van. Alan built his RV-3 with the intention of installing our engine and achieving speeds above those of stock RV-3 so made numerous mods such as thicker tail surfaces and balancing. I don't remember that Alan did any firewall or forward fuselage mods you mentioned. We have done none of these on our RV-4. Structure is stock, firewall rearward on -4. But your concerns are very good-- Alan's straight/level speeds are above VNE of stock RV-3. Normally most higher h.p. engines above standard power are heavier. But our 200 h.p. engine weighs 265 pounds. This includes propeller reduction gear, fuel injection, starter, alternator, ignition and water pump. So installed weight is approx. 40-plus lighter than O-320. Bottom line: if you limit speeds our 200 h.p. engine should not pose structural problems. But check with Alan regarding his airframe mods and engine/airframe integration. His telephone: 209-447-1112. You may also want to contact Claudio Tonnini. He is building RV-3 and has placed a deposit for our rotary. He has been in contact with Alan. Also Stan Blanton has ordered one for his RV6A--his tele: 806-799-4664. Stan also on RV list. In your earlier note you asked recommended constant speed prop for our engine. Ans: electric control. This probably means MT at this stage. We are looking very hard to find an in-flight adjustable propeller with a more efficient, thinner tip and less expensive. We hope to see you at Copperstate. We will have forum there in addition to Arlington before Oshkosh. Hope to have both RV-4 and Alan's RV-3 at Copperstate. ________________________________________________________________________________

The intent here was to clarify what Hartzell considers to be an aerobatic propeller, ie. no extension. The HC-C2YK can be used for "hard aerobatics". I am aware of the restriction imposed on one aircraft. There is also another airplane which uses the same propeller and engine combination as what you've stated and has no restriction. Engine and propeller combinations are approved by Hartzell, Lycoming and the airframe manufacturers on a specific airplane basis. Not all airplanes have the same resonant vibrations. Here's a good question for you. Has the RV series been tested for vibration using any of the propeller engine combinations currently installed? The answer is no. We are all testing what we have installed. Maybe some day Van's will embark on this task so we will all know or have a better idea on how the creation we have assembled reacts. That's why standards we're established in the airplane industry. To give us some degree of comfort knowing it has gone thru some sort of certification process. These are homebuilts.

Ive been saving towards the RV8 for some time now, and im getting a lot closer to purchasing a large section of the kit ie emp, wing, fuse, tools etc. I realize that they are a very clean aircraft and require absolute care and attention in the down line. >From what i read on the list i understand that they have a stronger wing etc than a cessna 152 aerobat. I most certainly can not afford the substancially higher price of a Pitts or Extra or Giles 200 or any of the very dedicated aerobatic planes. The cessna aerobat performs a lovely spin and a good clean snap roll. But i would be very dissapointed to think that i would have to stay with flying aeroclub ie hire cessna aerobats for the rest of my life. Most of the ones ive flown have so much crap in them that falls to bits during aeros, doors that suddenly fly open during slow rolls and to cap it off that annoying high wing with its piss poor aerobatic visibility. Its no wonder to me they are labeled spam cans. Im head over heals in love with the RV8 but would be dissapointed to think they cant be used for sportsman aeros with maybe a little intermediate as well. I have a friend here in Kiwiland who is really doing great in his RV4 with intermediate aeros. What gives ? Could I get some comment on exactly what the RV8 is safely able to perform as far as aerobatic manouvers, also i see they are a -6 g aircraft is this a usable -6g or is all the extra cost of inverted fuel oil and injector system just going to be a waist of time and money.

Subject: Van's Online Ordering - Try it!
Hello fellow RVers, I just wanted to give a quick pirep on Van's new Online Ordering available via the Internet at "order(at)vansaircraft.com". Last weekend I discovered I needed a few 'things' for the 'ol -4 - some bolts, the strips of steel to connect the rudder peddles to the cables, the elevator pushrod tube (Hey how'd that get so short - I cut it three times and it *still* wasn't long enough!) - you know, stuff that comes in handy for those 'other' projects every once in a while. At any rate, I shot off a quick email message on Sunday to the 'order(at)vansaircraft.com' address, included the quanity and part numbers I needed along with my Plans Number and shipping address and then sat back to see what would happen. Boy, was I pleasantly suprised! On Monday morning I received a conformation email from Bill Benedict indicating that my order had been received and placed in their system. On Wednesday morning the UPS truck dropped off my parts! Now that's service! Thanks to everyone at Van's for the great service! Keep up the good work - we builders appreciate it!

Go ahead and set the edge distance, check for the same distance from the tips to a common point on the fuselage and that the leading edges of both wings are in a straight line (ie not forward swept) and drill. Then set the Horizontal Stabalizer with 0.5 degree incidence. The fuselage may be flying downhill all the time, but that is all. The RV-6/6A use a 1 degree incidence with the same wing span, same wing area and same fuse length (almost). When checking incidence, don't use just one area on the wing. Check several places along the span of the wing. Even though it is built with no twist, there will be a certain amount of wave in the wing. Probably the most effective area on the wing for roll moment is about 2/3 of the span out from the fuselage. I would give this area a little more credit when setting the incidence.

Subject: Re: Aerobatics
> >Ive just read some discussion on props and aerobatics etc. >The comment was made that Vans does not recommend spinning or snap rolls >in the RV series aircraft. The RV-4 and -8 are different in design from the -6/6A (just in case no one noticed). The -4 and -8 are capable of spinning without qualification. The -6/6A can be spun, however it has a spin characteristic that Van does not feel comfortable with, so he does not recommend spins. There are several people I know who spin their -6's without hesitation and have no problem with it, but they limit the number of turns and perform a recovery before the spin develops past the third turn. The wide bodies (6/6A) have a characteristic of developing a tight high rate of spin some time after the third turn that requires the pilot to move the stick to a neutral position, apply opposite rudder and 'wait' for the recovery to occur. The -4 will recover 'hands off', the -6/6A will unless the aircraft gets into the tight spin. You can read more about this if you look back through the RVators. Van wrote a detailed description about his testing, but I don't have it at my fingertips. Snap rolls can be performed in an RV if you slow down to the recommended entry speed. I look at a snap maneuver as something that was developed to force a roll in an aircraft that would not perform a graceful roll. Please don't flame me on this, it is said in jest. Until you enjoy the rolls in an RV, my statement may seem unfair. > >The cessna aerobat performs a lovely spin and a good clean snap roll. >But i would be very dissapointed to think that i would have to stay with >flying aeroclub ie hire cessna aerobats for the rest of my life. Once you fly aerobatics in an RV, even if you cannot perform a snap roll, you will probably never want to get back in the aerobat. Well, maybe once, but you will see how akward it feels next to the graceful handling characteristic of an RV. I'm beginning to sound like a salesman, but the more you fly 'em, the more you appreciate 'em, especially in the unusual attitudes. >Most of the ones ive flown have so much crap in them that falls to bits >during aeros, doors that suddenly fly open during slow rolls and to cap it >off that annoying high wing with its piss poor aerobatic visibility. >Its no wonder to me they are labeled spam cans. You are experiencing the results of the airframe flexing, and flexing means moving, and moving means wearing. The RV does not flex as much because it is more rigid. Also, since it flies around the basic manuvers instead of falling through them, the airframe does not need to flap (yield) as much. >Im head over heals in love with the RV8 but would be dissapointed to think >they cant be used for sportsman aeros with maybe a little intermediate as >well. > >I have a friend here in Kiwiland who is really doing great in his RV4 with >intermediate aeros.

The spars are symetrical, so the loading can be symetrical. What is the -8 capable of performing? You can start by seeing what the -4 is capable of performing! Van has not uncovered any characteristics that we want to limit the aircraft on yet. >Respectfully > >Warren Jones RV8 hopefull kiwiland Does Van recommend any of our aircraft for 'hardcore aerobatics'? No! Does he recommend sport aerobatics? You betcha! Is building an RV a waste of money? I don't think so! Even if you don't like it (and there is probably someone out there who has not liked it), you can sell it for more than you have invested in the flying aircraft. Is that a waste of time and money? Maybe a waste of time, but a lot of builders have just as much fun building as a lot of us have in flying. Hope this did not offend anyone, I just like to put little quips in to bring a smile to the readers face. However, snap manuvers and spins just become so unimportant when you have the capacity to perform aileron rolls, barrel rolls, loops and all the combinations without having to dive to pick up speed, and if you do not have the inverted 'stuff', these can all be gracefully done in the positive domain (positive g's). Today, I took one of our employees who is blind up for his first fright, I mean flight in a small plane. With just positive manuvers, we did rolls and loops with me describing where the horizon was all the time. He even got a little stick time. Had no problem as long as we were in trim, but when the plane accelerated and the pitch trim was out, we had one roller coaster ride! This fellow has been blind since birth and has a remarkable sense of presence. He got more sensation out of a 3.5g turn than he did out of the roll and loop. By the way, we did all this in a -6A, even prolonged stalls so he could experience the stall characteristic. Bill Bill RV-4-180 soon.

True a dipole is just a dipole, but most of those expensive aircraft antennas are not just dipoles, but then again some are. Consider that there have been simple stainless com antennas out there for airplanes at a relatively low cost also. I think about 10 yrs ago I paid about $25. The difference of coures is quantity produced, and the fact that it had special little insulators for mounting it to the skin, etc. All in all it worked as good as the expensive one. but was limited to 150 mph, and didn't look as good (if that matters).

I would like to know on what basis you make this claim? Have you flown an RV-6? All of the RVs are truly sweet aerobatic mounts. They have light controls and quick, crisp response. They have enough power to do any maneuver in the book from level, cruise flight. The low angular inertia about every axis, in particular, delights me. I could wish for more power and more roll rate, but then I have never flown any airplane that I thought had too much power or too much roll rate (including the F-15!) I am a 2500-hour military instructor pilot. I know several retired fighter pilots, now flying airliners, who fly RVs on the side because they handle like little fighters. The first time I got a back-seat ride in an RV-4, I had to have one. It is one of two airplanes I have ever flown that felt just right from the moment I grabbed the stick. >My question is...... >On an RV-6 without inverted systems, what kinds of maneuvers can be >flown safely? As in any airplane, you can fly any maneuver in the book (and any other maneuver you can invent) as long as you stay within the capabilities of the airplane and the pilot. Don't pull more than plus or minus six Gs, don't exceed 210 mph, and without an inverted system, don't push neggies until the engine quits. (I know that several guys race RVs around 230 mph, but I'll bet they aren't pulling any significant G.) The rest is entirely up to you. All of the ex-military pilots I mentioned are flying without inverted systems, and all do extensive aerobatics. I am having Everett Hatch build me an O-360 of about 195 hp with fuel injection and inverted fuel and oil. It is expensive, but fits well with my intended purpose for the airplane. I intend more aerobatics, formation, and dogfights than pure cruise flight. Just rationally examine your purpose for the airplane, weigh the costs against the benefits, and decide for yourself!

Subject: RE: 3-bladed props
From: tcraig-stearman(at)juno.com (John T. Craig-Stearman)
Date: May 10, 1997
Don't be too quick to jump for a three-bladed prop. As in all aircraft choices, a three-bladed propeller is a compromise. Be aware that aerodynamic theory suggests a three-bladed prop will be less efficient than a two-bladed prop of the same design. The reason is that each blade operates in the wake of the previous blade. This effect becomes more pronounced as you increase the number of blades. So why do some airplanes, particularly those with more powerful engines, use three (or more) blades? Remember that each propeller blade is a wing. As the lift ( thrust) that the propeller must produce increases (with increased power input), each blade operates closer to its maximum coefficient of lift. Just as in sizing an aircraft wing, the designer must increase the propeller "wing area" in order to reduce the blade loading. But now another design factor comes into play. It may be impractical to simply increase the blade length because of decreased propeller clearance from the ground. The designer may opt to increase landing gear length, but this in turn increases weight, cost, and complexity, particularly for retractable-gear airplanes. A second option would be to increase the area of each blade, as in the paddle blades on the C-130, P-51, and SU-26. A third option would be to increase the number of propeller blades. I noted at least one post suggested that a three-bladed prop would lead to more speed. This is not accurate. The design point that would require a switch to three blades would be the low-speed, high-power regime, most notably takeoff and aerobatic flight. So before you buy a three-bladed prop, consider the costs and benefits. A three-bladed prop will be more expensive, less efficient, and heavier than a two-bladed prop of the same design. On the other hand, it will run more smoothly, be able to handle higher power loads, and will just look cooler. Look around at airports. I doubt that you will find many three-bladed props on airplanes of 200 horsepower or less. An exception, as in the case of the Lancair, would be airplanes with very short landing gear.

Subject: Wing Skins
Juts got done drilling left top wing skin. I have some oil canning between two outboard bays. Seems like I'm really good at introducing it in my bird! Two questions: 1) I can install an additional "rib" between two main ribs much like w-625 near the bell crank. Anybody know a reason not to? 2) I drilled to spar first, then expanded 2-4 holes at a time from center to edge, with the center leading the march to the rear spar. How do others drill their skins to prevent oil canning? Should I just drill the main spar, then march down all ribs equally to the spar? The BOTTOM skin was perfect (wouldn't you know it) using the method I described.... Jon Scholl RV6 bcg007(at)aol.com ________________________________________________________________________________

The three blade electric variable pitch Ivoprop Magnum prop has been running very successfully on the Velocity with a Lycoming IO-360 of 200 Hp. Anyone notice if it was at Sun'n'Fun?? The Ivoprop three blade prop weighs the same as the fixed pitch Sensenich Metal Prop for the O-320, and costs $1,960. It is a bolt on to ANY Lycoming (as well as my dry flange LOM). And if you want to try the prop as a two blade, just install it with two blades. (Of course, the two blade prop is 5 pounds lighter than the three blade prop.) Velocity convinced Ivo to build a high pitch version of the Magnum prop for the Velocity. So far Ivo has only made a pusher version. They work on pusher aircraft and LOM powered RV's. :-) When I get my Dec. 96 annual completed with Lamb tires, Klaus wheel pants, Tracy Saylor gear leg fairings, Matronics Fuelscan installed, removable VS COM antenna, an electronic governor for my Ivoprop, I'll get a chance to try out a set of the new blades.

Plan #18a shows the fuel tank construction for the RV6A. Both the root and outboard rib tips have the addition of a small reinforcement piece which is riveted on with AN426 rivets. It seems logical that the flush side of these rivets should be on the outside of the tank, since I can see no use for the flush side inside the tank. However, I see no apparent reason for them being on the outside. A brief word on this will be much appreciated. I've checked every plan sheet with this part on it, and the photos in the binder, and see no apparent reason for their being flush rivets. Thanks much for a reply.

Subject: Thoughts on COMM antennas
I've been watching a thread on this subject. I think it started when someone asked why that little stick of metal had to cost so much money. There've been a number of responses most of which contributed good and useable ideas but I'd like to summarize some of what I've read and organized in no particlular way, add a few thoughts of my own: VHF comm antennas operate over a range of 118 to 135 MHz here in the US . . . similar ranges elsewhere. The classic solution to comm antennas on airplanes has been abasic, 1/4 wave, mono- pole antenna using the aircraft skin as a ground-plane.The antenna's radiating part has to be electrically connnected to the coaxial feedline which carries signals between antenna and transceiver. The most durable materials for construction are the steels, most popular of which is a stainless. Copper, brass and alluminum have been suggested and used successfully for enclosed antennas in composite structures but they are difficult to make live on the outside. Non-ferrous materials work-harden and tend to break off after some priod of time "waving in the breezes". Electrical connections to copper and brass are easy . . solder it. Aluminum and steels need soldered or solderless terminals attached to the radiator with some sort of threaded fastener. Many years ago, Cessna fabricated their own antennas by threading the end of a 3/16" stainless rod, mounting the threaded end through a two-piece, ceramic insulator in the cabin top and holding the whole business in place with a nut inside and one outside. A third nut attached the coax center conductor's crimped on terminal to the base of the rod. Another terminal attached the coax shield to the skin adjacent to the antenna base. The antenna would have worked best if left straight but performance was only slightly degraded by bending the rod aft to give it a rakish appearance. This design suffered from the ususal problems. Things like this stuck into the airstream like to shake rattle and roll. Skin doublers were wont to crack around the hole where the insulator came through. They leaked when it rained. They would also tend to loosen up and if over tightened by a zealous mechanic, the ceramic insulator would give it up with a sound like cracking ice. None-the-less, the cost of fabrication and installation was attractive and like most maufacturers then and since, cost out-the-door was a MAJOR driver, not cost-of-ownership AFTER it got out the door . . . Aluminum and brass can be used for antenna rod material but be prepared for periodic replacment. These materials work-harden and break off regularly. Steel antennas can resonate and vibrate in the wind and break too. I was riding shotgun with my sister on a driving trip a few winters ago. We were getting some very light precipitation and the OAT was about 29 degrees. I watched in fasination as the am/fm antenna right out the window from me gathered ice. As it's shape and mass changed, I watched it start to "hum" . . it had a perfect full wave mode with a node right in the middle that stood perfectly still. As the ice coating grew, the amplitude of the hum grew too. My enjoyment of watching the demonstration ended when the antenna just disappeared! It broke cleanly from the fender mount right at the base. People are generally unaware of the fact that MOST of an antenna's good work happens in the first few inches off the base. The design I just described had a substantial percentage of it's working length INSIDE the cabin. The rod extended through the cabin roof about an inch, an the coax cables I saw had about another inch of exposed center conductor hanging out from under the shield before a terminal was installed. This material is PART of the antenna's overall length at the base where the critter is trying to lauch your signals into the ether . . . the part inside the cabin was willing but crippled. There was some mention of a radio shack automotive antenna as a likely candidtate for vhf comm conversion. I bought a 12-1322 radio shack antenna for $10. First, the conducting part is all one piece, not telescoping (good). The base is designed for installation through a 7/8" hole with all the work being accomplished from outside. All of the metals appear to be stainless or plated except for the mounting barrel which appears to be injection molded aluminum. First, the coax feedline supplied with this antenna would have to be discarded. If you cut it open you'll find a very tiny center conductor designed to provide a low capacitance, hi-impedance connection between antenna base and the input stages of an automotive a.m. radio. This coax is unsuitable for connecting the 50-ohm output of a transmitter to the antenna. If you look inside the connector at the base of the antenna, you'll see a stainless steel pin which is the machined down butt of the antenna rod. The original connector has a hard copper female sleeve that gets a fair grip on this stub when the connector is engaged. In am/fm radio service, this joint carries very tiny currents in a receive-only mode. While you're transmitting, a 5 watt transmitter will generate approx .3 amps in this joint. A lot of degredation in this connection will go un-noticed in am/fm applications while vhf comm transmission requires a solid connection. I think my approach would be to drill a piece of brass rod for an interruption fit to the stub. Turn down the other end for a solder post . . . .06 to .08" diameter. Or tap it for 8-32 nut. Clamp the antenna rod in a vise and drive the brass terminal down onto the stub. When mounting this antenna, keep in mind that supporting the whole thing on a skin area surrounding a 7/8" hole is too much load on the material. A .06 or better doubler should cover at least 4-6 square inches around the mounting hole. Before installing the doubler on the skin, drill a countersunk hole for a 6-32 or 8-32 flat head screw as close to antenna base as possible and with head of screw against the underside of the aircraft skin. Rivet the doubler to the skin with generous sprinkling of flush rivets. When the antenna is mounted, attach RG-58 coax center conductor to antenna rod and shield braid to the ground stud provided on the doubler. Use an SWR bridge or antenna analyzer to measure the antenna's characteristics at 125 MHz. Use Dremmel with cut-off wheel to score the antenna rod all around and then snap it off. When the optimum length is achieved, use the hand grinder to smooth and round the tip of the antenna rod. Optimum performance dictates that the antenna be mounted in a vertical plane. One respondant to this thread talked about using "wingtip" antennas for comm . . . it was an RV'er I think. I'm wondering if he is considering the gamma-matched, monopoles offered by Bob Archer and described in a variety of kit-type newsletters. Be advised that these antennas are suitable only for vhf navigation (omni) because they are horizontally polarized. Another respondant suggested that amateur radio 2-meter antennas may be cut down to a length compatable with VHF comm operation. He did speak to the existance of "coils and matching circuits" in the base but seemed to offer the notion that an SWR meter doesn't lie when you trim the aforementioned antenna to the length required to lower the SWR at the frequency of interest. Be advised that 2-meter (144-148 MHz) ham antennas are generally 5/8 wavelength at the frequency of interest and require a matching network in the base that really clobbers the antenna's overall performance when trimmed to operate in the 118-135 range. If you are considering such a modification, take steps to bypass or remove any such matching hardware before trimming. Just because the SWR can be lowered to some satisfactory value doesn't make the antenna work. A 50 ohm resistor has an SWR of 1:1 and radiates not at all . . . it does get hot but we're not building coffee warmers. Without test equipment, it's impossible to optimize an antenna in place. Without flying the antenna with test equipment -or- taking the installation to an antenna test range, it's impossible to put meaningul numbers on an antenna's performance. Be cautious of suggested designs where individuals say, "it really works great!" Consider that 95% of your communications occurs at within 10 miles of the other station. A wet string hung out the window might be said to "work great". The load it presents to your transmitter, and the efficiency at which it covers the azimuth around your ship with readable signals are all non-quantified in "works great" evaluations. Further, you'll never know about the signals you DIDN'T hear because of their position in some deep null of the antenna pattern around your airplane. If you enjoy the experimentation and have access to at least rudimentary test equipment (I have an MFJ analyzer that I rent out for such endeavors), then by all means go for it. If you're trying to save money and wince at the idea of spending $50-100 for someone's production model but don't feel comfortable with the experiment, then perhaps the purchased antenna is the better deal . . . you can spend a LOT of time experimenting in the dark. Be cautious also of no-name commercial offerings. Bob Archer's antennas are well built and based on good engineering principals. There are others with 'matching networks' and ferrite beads that are questionable. Tiny, lumped matching networks may indeed present a low SWR to the transmitter but they are very lossy. Ferrite beads over the coaxial feedline to a dipole antenna contribute so little to its performance that there's no value in installing them. Simply attaching the coax conductors to the center of a dipole will produce useable peformance that is not improved by addition of the ferrite beads. For metal airplanes, a Dorn-Margolin or Antenna Specialist monopole is about the best performing antenna you can build or buy. It has a fairly generous base to spread loads, it's been perfected over the years to provide reasonable service life in 200 mph winds. It's electrical connection is made via coax connector; ALL of the antenna's active length OUTSIDE the airplane. On composite ships, home-made or commercial monopole antennas must have a metalic "ground plane" under them. Bob Archer has some half-wave dipole offerings that do not require a ground plane. My objective here is NOT to discourage experimentation -or- to throw water on the do-it-yourself endeavor. Irrespective of your reasons for deciding to buy or build, the outcome can only improve if you arm yourself with knowlege. With antennas, the devil is in the details. Regards, Bob . . .

The callout you mention is for the inboard end, actually the angle piece that attaches the wing tank to the fuselage. It is thick enough to countersink for flush rivets. At the outboard end, you would have to dimple. I had the old plans with sheet 18 as well, which do not have the tip reinforcements and call for AN470 rivets for the attach angle.

Fellow RVrs... My mid-time Lyc O360 is missing 2 of the primer fittings that srcew into the top of the cylinder. These are the little jobs that have a goofy 1/8th tube fitting one side that has a small tapered brass bead that slips over the tube and is then sandwiched between the fitting and the screw on 'cap'. On the other end of the fitting there is there is a 1/8" pipe thread with a 1" long mandrel that sticks into the cylinder head. In the mandrel are two very small holes (maybe 1/32") that allows the fuel to flow into the head. With that said, I have some questions that I hope you-all can answer: 1) What is the part number for these? 2) Are these Lycoming or AN parts? 3) What is a good source for these babys? 4) Can I just use a 1/8" flared tube to 1/8" pipe fitting instead of this special fitting? 5) Depending on the answer to question #4 above, what type of fitting should I use to obtain the manifold pressure? Cylinder #3's primer hole is a good place to pick up the manifold pressure, right? Instead of bringing the fuel into the cockpit for the traditional primer pump, I have opted to keep that mess off of my feet and legs and got thi nifty little electric valve that is in the ACS catalog. My plan is to run a 1/8" tube from the top of the gascolator to the electric valve, and then from the electric valve via 1/8" tubing array to the primer fittings. My question is this; will the pressure from the boost pump (standard Van's issue Facet job) be enough through the top port in the gascolator to get fuel through the primer lines? Finally, does it seem like a good idea to put a bulkhead AN fitting in the firewall for the fuel line? A bushing alone just seems like a bad idea.

There's plenty of pressure to prime the cylinders. In fact, you only want to push the contact switch for the primer solenoid for about 1/4 to 1/2 second; you'll have plenty of prime. One note. I wired the solenoid so that it could only be energized when the boost pump was on (took the hot lead for the solenoid contact switch 'after' the boost pump switch). My reasoning was that I would only need the solenoid open when the boost pump was on anyway and this way there is no chance that the solenoid could become energized inadvertantly.

A friend of mine has just taken a KLN-88 LORAN out of his panel. It=92s the one with the green CRT and moving map. Does anyone know if it=92s worth anything and if so how much it=92s worth. I think it's about 5 to 1= 0 years old but I don't know. I understand that LORAN is going to be shut down in about 3 years so it might not be worth much. Any ideas?

Subject: Sport Aviation Aerodynamics
Yesterday I was driving past the Sacramento Executive airport and happened to see an open hanger with two RV-6A's in view. Being a shy type I barged right in and being RV'rs they were most cordial about it. I mentioned that I had just seen the article in Sport Aviation about the aerodynamics study of an RV-6 and asked if they'd read it. "Well, yes.........The airplane that was the subject of the study is right behind you." Duuuuuuuuhhhh. Yeah, I really read the article closely. It's a shame that the article did not have a photo of the aircraft that they modified because it is beautiful! The wing tips are kinda funky with a flip-up of about 45 degrees to a sharp outer edge but the convex fillet at the wing root definately looks well thought out. The most interesting aspect though, was the cowl. Two, five inch circular cooling inlets with rubber sleeves to connect them to an internal plenum whose top is a close-fitting carbon fiber deck. The air inlet is much just barely below the spinner and clears the prop by less than two inches. Inside the intake is the spinner off a model airplane that directs air flow into a plenum surrounding a conical airfilter. Access to the dip stick is through a neat little door that is hinged inward and held shut with a magnet. This is one neat airplane. The best part is that he's going to be selling the cowls to any and all comers! I was told that more info is available through the internet site at Barnard.com but I've not been able to link up to it. If you happen to spot it, please post the location.

/What setup are people using for an AM/FM antenna? I certainly don't want /35" whip antenna on the outside of my airframe, but considering the far more /suitable operating environment, I would think you could get away with a much /shorter antenna. Ideas? . . . . You can run RG-58 to the //outboard rib terminating with a crimp type BNC female bulkhead connector. //Use any old 30"-31" length of wire draped into the fiberglass wing tip //connected to the center of a BNC male connector. . . . . just run RG-58 out to //the wing tip and strip the last 30" or so of the jacket and shield off //(leaving just the insulated center conductor). You might cover the cut end //to eliminate the possibility that it might short out against any exposed //grounded metal. One can certainly try this and if it functions to your satisfaction, then why not? You should know that the input to a car radio's antenna jack is NOT characterized for 50 Ohm coax like RG-58. In a recently published article, I mentioned that if you cut open the cable supplied with an automobile am/fm antenna, you'd find that the center conductor is MUCH smaller with respect to the inside diameter of the braid than you'll find with communications coaxes like RG-58. RG-58 has a capacitance of about 30 pF per foot, the wire I just took off the Radio Shack antenna measures about 12 pF per foot. The input to a car radio is charactized for a very inefficient antenna at the frequency of interest. It's so far from the ideal 1/4 wave value that it becomes little more than a short probe which MUST operate into a very high impedance receiver connection. This is why am radios for cars have an "antenna trimmer" capacitor available from the outside and a sticker that suggests what frequency it should be adjusted for optimum reception. A 15 foot piece of RG-18 would have a capacitance on the order of 400-450 pF . . . . MUCH higher than any ordinary radio expects to see. So, if you find that the suggested installations perform poorly, work toward (1) reduction of the length of feedline and (2) use automotive antenna cable assemblies if possible. None the less, the 31" whip is a MUCH better f.m. antenna at 100 MHz than the same antenna is for a.m. at 1 MHz. If you don't care about the a.m. reception, then I suspect that RG-58 will be okay. If the 31" wire is not standing away from structure of the airplane, it might work better if shortened. A look at it with an antenna analyzer would help you adjust it.

Aha, you are assuming that the effect of a propeller blade passing through the air is restricted to just the actual path of the blade! Not so. Have you ever seen photographs of air-to-air refueling in progress? Note that the receiver is always at a significantly higher angle of attack than the tanker, even when they are the same aircraft type. Both airplanes are obviously traveling at the same speed. The receiver is flying in the downwash generated by the tanker, even though the receiver is at a lower altitude and not flying in precisely the same flight path. Empirical testing of propellers (at least the data I saw some ten years ago in aero classes) does show decreased propulsive efficiency as the number of propeller blades increases.

Craig, This was very close to problem #1 as I remember. You can grind the side of one of your dimple dies (don't think about it, just do it) to get better access. You can think carefully about where you put holes (may not apply to pre-drilled kits). You can countersink if there is enough metal. One technique that I found helpful in various places was to get the Pop-rivet dimple die set from Avery's and grind this down viciously (almost to the edge of the dimple). These dies do a very ordinary job but after you have used them you can "touch up" the dimple with your countersink which will now remove very little metal but leave a nice recess for the skin dimple to sit in. It is worth having a good think about all the various techniques because you will be using all of them in the next few years.

I commented on this to Avery's almost a year ago, but they haven't seen fit to upgrade their toolkit. Like you I guess, I was not happy to find that having spent a large sum on an "RV Starter Toolkit" I needed to purchase yet another tool to do the second task in the project :-(. It was just the first of several frustrations; accept it, and get on with building. (In case anyone gets down on me for badmouthing Avery's: they're a fine company to deal with, and I'd recommend them to anyone [and no, Avery's don't pay me anything]:) Point your browser at http://www.pec.co.nz/~frankv/bunny1.htm for lots of IMHO handy hints on empennage building. >I think I am going to have to purchase >the vise grip dimpling tool to do this. My question is: Is this the correct >tool? Or the only tool? or is there another way. Signed, a beginner. FWIW, I recommend you buy both a set of hand-squeezers and a vice-grip dimpler. Here's my experience: I made a vice-grip dimpling tool (you'll need a source of quality tool steel for the dimples, a lathe, and welding equipment, or friends with these). The results were adequate but not great. Later in the year, I bought hand squeezers from Avery's to squeeze the 3/32" skin rivets... a bonus is that the dimple dies that came with your C-frame tool also fit in them. The dimples produced are better, and the hand squeezers are much easier to use than the vice-grip dimplers (less muscle-power needed). For tight spots (eg near the TE of control surface ribs) I still need the vice-grip dimplers. You might want to consider vice-grip squeezers with mounts to use the C-frame dimple dies (they're in Avery's latest catalogue) instead of a dedicated vice-grip dimpler.

Craig, the squeezer is definately an invaluable tool for dimpling. I don't have the "vice grip" dimpler and during my construction of the HS I haven't needed it. I ordered the 3" yolk with my initial order and it's worked great but does tend to flex a little with squeezing 1/8" rivets. I recently ordered the 1 1/2" yolk and it's much better. The "C-Frame" tool should also allow you to dimple the spar where the flange strips are countersunk and need to attach. I've used the squeezer to do all the dimpling on my HS and VS so far. Obviously the C-Frame tool will be needed to dimple the skins. >>I was hoping someone could answer a dimpling tool question.

Or I could fix it with a patch. My favorite idea is to fill the four holes in the bars that are riveted to the HS with segments of AN bolt, swedged and staked in followed by new holes immediately next to them. I'd then use a larger washer to ensure that the fillers remained in place. Another option would be to double either these or the verticals. What do you all think?

It also adds length to the cooling inlets before the air gets to the plenum for better ram recovery. I.E., much better cooling. This also enabled a longer intake box for better ram recovery on induction air. Most factory airplanes have a loss of 2 to 3 inches of manifold pressure due to poorly designed airboxes. We have obtained 1" over ambient at cruise settings. What this equates to is better power at all flight conditions. All this with ram-filtered air. We are filtering air 100% of the time. I think the 200 hp fuel injected Lycoming with 1 electronic ignition combined with the new cowling and cooling plenum to be the most efficient & economical as far a speed and fuel burn are concerned that one can put in an RV-series plane. I'm sure I'll pick up some flak on that one. If your looking to improve on a great airplane this is one way to do it. If you want good looks, speed and efficiency or just want something different on your RV this may be what your looking for.

Steve's reply Jerry you have just convinced me thru your own words that RV's have too much cooling. What this equates to is excess drag. You do not have an optimized system. Is it perfect no? Does it work, yes. Cessna 150's and Piper Cherokee systems work also, but does that necessarily make them efficient? There is a large difference in speed between those airplanes and RV's. The faster an airplane goes the smaller the inlets can be. We have addressed this issue in the B.A.C "holy cowl". We have reduced the cooling area inlets by 40% over stock configuration, yet I can still keep a 200 hp engine cool both in oil temperature and cylinder head temperatures. Reducing the inlets this much decreases the amount of drag due to less cooling air spilling over the outside of the cowling. You are getting reverse flow out of the cowling with the stock inlets. In reference to my quote on increasing the speed 20-25 mph by installing 200 hp has been taken out of context. If you read it carefully you will notice that there we're other changes as well. Increasing engine power by 20H.P. in an RV will get you approximately 6 or 7 mph. There was also a change from 180hp-wood prop to a 200 hp engine and constant speed. We conducted a very accurate flight test last weekend with the following data. Conditions:8500 ft. density, full throttle,2700 rpm, fuel flow 11.5 gph with a true airspeed of 218 mph,(IAS of 195 mph)over a specified course. There we're no special preparations on the airplane. I cruise at full throttle 2450 rpm at 10,500 ft and burn 8 gph at a true airspeed of 205 mph. Now keep in mind this is an RV-6A nosedragger. These are honest numbers. This was a true 75% power run. I'm curious what other RV's weigh empty. Could we get a little response back from the readers. List engine, propeller and type. I think it's important that the individual building an RV consider the aspects of the design in it's entirety and be comfortable with that decision to own one. The question as to why this was done is simple? Let's see how many of us fit this category: I just had to put a slick tire on my Schwinn stingray The 57 Chevy Belair just begged for a four barrel and headers-don't forget the glasspacks-the hood scoop just looks great I wanted the red flames because it looked cool. I really like that added horsepower for the high airports on a hot day. As long as man has been around we all look to improve things. Need we ask why? This is what we call progress. And if the RV can't be improved upon I'll eat your hat. Does Jerry have a bone stock, built to prints, airplane, come on Jerry you changed something you did'nt like, did'nt you? As far as exceeding mfg's design limits beg the question: How is VNE (never exceed speed)established according to the FAR's? This is a question you need to ask Dick Vangrunsven and ask for more clarification. Hope everyone enjoys the interchange of ideas and information-no opinions here.

Craig, A couple of suggestions... If you are having a tough time dimpling this area with the squeezer, you'll probably have a tough time setting the rivets as well. Watch your edge distance, but don't put the holes too close to the spar web or the HS-409 reinforcements. The other tools I suggest: Pop-rivet dimple die. I know Avery sells them and Cleveland probably does, too. You'll need something like this if you want to dimple the holes closest to the trailing edge bend of the control surfaces. Avery and Cleveland sell dies with 1 side ground off (if you don't want to grind down your only set). At some point, you WILL need to get into a tight space. (Sounds like you are there now.) I also ground the front off one of my squeezer yokes in order to get into tighter spots. I don't own the vice grip dimpler. Haven't missed it yet. There are lots of ways to accomplish the same thing and most don't cost as much as a specialized tool you use only a few times.

Hal, I am not sure about the side to side tolerances but your suggested repair does not sound as if it would comply with standard aircraft repair practices. Those bolts are all that stand between you and eternity and there has been an RV crash which seems to have related to non-standard practice in the same area.

The slugs are a common item that can be purchased from a Ham Radio store. They will run about $65 ea. You should only need one for most aircraft use, (the same slug will work in the 2m Ham Band also) but if other frequencies are of interest to you the meter will work well no mater what frequency you are interested in, you would just have to purchase the slug of choice for the additional frequency.

It seems he was accustomed to Cherry rivets which have requirements that the mandrel break at or above the level of the rivet head. I called Van's and they faxed me the Avex spec sheet which says the mandrels break off beneath the rivet head. In fact, they deem this a product advantage, as there is no rivet head shaving required. I passed this along to the counselor as we have a half-dozen or more RVs in our chapter. I assume from the spec sheet that in the case of Avex rivets, the mandrel contributes little to the shear strength. As a reality check, I inspected a friend's 6AQB, and the factory-installed LP4-3s had mandrels that were from 1/32 to 5/32 below the top of the rivet head, some well below the shear plane. Happy riveting! Dennis 6A fuselage in jig ________________________________________________________________________________

This is a very good reason I will never smooth over Acetone will soften, if not remove lightweight Bondo body filler. You have to keep the Bondo wet with it for a few minutes, and it helps to scuff the surface of the patch first with fairly course sandpaper, like about 100 grit. I use a course ScotchBrite pad wet with the stuff. Wear rubber gloves (latex will dissolve) and try to stay upwind of the fumes.

Subject: Re: ACK ELT installation
Richard, I installed the same ELT on my now flying RV-4. Let me tell you what I did and how it worked out. I put the main unit on the ledge in the baggage compartment over the elevator bellcrank. This as it turned out not to be a good place for it because it does move the C.G. aft and you definatly don't want that, it cuts down on the passenger weight and baggabe weight as well. The batteries in these things add up in weight and that was fairly far aft of C.G. A better place for it on the 4 is over the batterty compartment as far foreward as possible. It is a little agrivating when you go to get to your battery but how often do you do that anyway. I used the antenna they supplied and mounted it about 16" in front of the verticle fin. It does not bend back as far as you might think. I have pictures of it during flight and it bends back about 45 degrees at the tip. I investigated other antennas but they all are the same length. I mounted the indicator panel at the bottom right of my instrument panel. Also don't forget to put the battery in the indicator panel like I did. The remote indicator panel will not work without it and you cannot test or reset your ELT without the battery. I hope this helps.

Even though I have flown the prototype Ivoprop Magnum prop (bad Idea to fly any prototype prop!!); I didn't add material to the outer third of the prop blade to "improve" the prop. I didn't run my engine at a critical RPM, such as, peak torque to maximize impulse loading. I didn't drill out the blade hub for large (stronger) bolts, which removed the blade hub structure. (Similar to removing wing spar material to reduce weight.) Bob did. There is a group of ULTRALIGHT pilots in Bob's area who feel comfortable modifying manufacturers props. If something happens, they EXPECT the prop manufacturer to replace their ULTRALIGHT. It has worked for them before. Bob's still trying. My opinion only, after talking to both Bob and Ivo, before I started flying the Ivoprop MAGNUM prop. BTW, the ULTRALIGHT Ivoprop and the MAGNUM prop are two totally different props. The ULTRALIGHT prop is normally flown on a two cycle engine. The MAGNUM prop is normally run on a four cycle four cylinder engine. This engine type has awful impulse loading into the prop, which is why there has been a thread on the RV list about the 12 pound vibration reducer.

Acetone or MEK (Methyl-Ethyl-Ketone) will soften the Bondo, but won't make it any easier to remove from the small crevices of a screw head. Use the pointed tip of an Exacto razor knife, available in hobby stores or the hobby area of department stores. Just scrape away thin layers of Bondo until a screw driver fits.

I have been able to do all my dimpling either with the Avery tool or my rivet squeezer, the exception being the screw dimples that I did with the special dimpling tool available. I admit, however that the vise grip tool would have been handy in places. The most important special tools are the dies ground for clearance in tight places, IMHO. You could modify the Avery tool by grinding the front end and arbor block back so that you could dimple the flanges by putting the female die in the arbor block and allowing the spar to hang below the tool. However, it would weaken the tool for wing spar rivetting, and is not something I would recommend in any case; it would be better to get one of the special tools.

For all you who are beginning building, in addition to the other items already mentioned you'll also need the #3 and #4 die sets that fit on a finish nail (used as mandrel) that are used in conjunction with a pop rivet tool, I think Wicks, Avery and Cleavland all sell them. In close areas like at the aft end of rudder, aileron and elevator ribs you may even need to bend the flange of the rib in order to install the die so a dimple can be made.

We bolted a sensor to the engine case and ran wires from this to the unit in front of the airplane. Then, the prop is "strobed" while the engine is running. He took some readings, we shut down and he figured how much weight was needed and then we went through the process again. After three runs, we were done. On the Sensenich, we ended up using two AN4 bolts, four large AN4 washers, two small AN4 washers and two AN4 365 nuts. These were placed side by side in two holes on the ring gear. Weights could also be put on the rear spinner bulkhead. The Sensenich prop was new and I had it static balanced when I took it to the prop shop to have it re-pitched. It checked out fine on the static balance but ran very rough on the airplane. A friend, who has a RV-4 with conical mounts, ran the Sensencih on a short flight and thought all of the needles on his gauges were going to fall off. He cut his flight short because of the tremendous vibration. Dynamic balancing smoothed the operation of both props considerably and I highly recommend the practice.

Subject: How to prime lots of pieces at once?
We received our RV6A kit (all of the kits, actually) today. It arrived in the early afternoon, and by evening we were mostly done with the inventory. Now I've got a question about priming. We'd like to prime as many pieces at once as we can, before we start building anything. Does anyone have advice as to how the part numbers (currently ink-stamped on the aluminum) can be best retained after priming? Stamping the numbers into the aluminum is a possibility, but presents dangers of its own. Another alternative would be to make a part number map of the pieces as they lay on the painting stand and re-write the numbers on top of the primer with a Sharpie pen after the paint dries. Has anyone else painted large numbers of parts at once? How did you remember which part was which? Any advice is welcome! Thanks in advance.

Subject: Serious Connectivity Problems [PLEASE READ NOW]
RV and Zenith List Members, There are serious problems with connectivity to the matronics.com domain currently. The email problems began Wednesday May 14 about 1am and are currently still unresolved. I have been in contact with the ISP, Slipnet, but I have basically received the run around. Current problems involve any email sent to the matronics.com domain, and an unrelated problem with certain files on the www.matronics.com web server, and finally connections problems to ftp.matronics.com FTP server. The later two problems began around Friday May 9 and would affect archive searching as well as viewing videos and bitmaps on the matronics web page. I am doing everything I can to motivate the ISP to resolve these issues. However, they have been less than responsive so far. Perhaps if the almost 1000 people on the RV and Zenith email lists each sent an email message to the Slipnet technical support (support(at)slipnet.net) and its president Ted Glenwright (ted(at)slip.net) indicating how important these services are to them, they might find some time to look into it. Refer to Slipnet trouble ticket numbers 43615 (web and ftp problem) and 43866 (email forwarding problem). --> Please do not post any messages to the matronics.com domain until further notice from me as your email will likely bounce. I will post a message when all has returned to normal. --> If you need to send me email, please send it to my alternate email address: dralle(at)roxanne.llnl.gov Matt Dralle Matronics RV and Zenith List Admin. -- Matt G.

You can put extra rivets in-between the existing rivets to pick up the edge distance on the 602s if you can maintain the 2d edge distance on the 610 and 614 in doing so.

Subject: Problems to Matronics.com Domain...
RV and Zenith Listers - Try as a might, I am still unable to motivate my ISP to resolve the connectivity problems to the matronics.com domain. Currently, these problems include: -> No incoming email to the matronics.com domain (started Tue 5/13) -> Most videos and graphics on the matronics.com web pages are not accessable (reported Thrusday 5/8) -> FTP connections to ftp.matronics.com do not work correctly (reported Thrusday 5/8) Fortunately, outgoing mail is still working allowing me to send messages out. Any messages sent to the matronics.com domain between Tuesday 5/13 and Thursday 5/15 were probably lost. Any messages sent to the matronics.com domain after Thursday 5/15 are most likely in queue and will be delivered normally when connectivity is finally restored. I will continue to contact my ISP's technical support on a daily basis until all of these problems are resolved. It seems incredible that a paying customer such as Matronics would have to work so hard to have these problems resolved, but alas that is support in the 90's I suppose... Please do not post any messages to rv-list(at)matronics.com or zenith-list(at)matronics.com until I post another message indicating that connectivity has been completely restored. Thank you, Matt Dralle Matronics RV-List and Zenith-List Admin. -- Matt G. Dralle | Matronics | P.O.

Subject: Matronics.COM Back OnLine!!!
Hello RVrs! After a great deal of hair pulling, my ISP finally has the matronics.com domain back online! I have tested the email pretty well and it seems to be working normally again. The problems with the Matronics Web and FTP servers have also been resolved. The good news is that the new directory structure imposed by the ISP (and consequently breaking most of my web pages and ftp server) have actually been an improvment. I have spent most of last evening and tonight redoing the web pages and ftp server to conform to the new layout and everything seems to be working very well. The best news is that the archive volumes are now available via 'http' hyperlinks instead of 'ftp' hyperlinks and should work with everyone's browser (hyperlinks via ftp is broken in many browsers). I have also been queueing any messages posted to the RV-List in the last week (starting about last Thursday) and will repost these to the List following this message. If you posted a message and don't see it, assume that it hit the bit-bucket last week sometime during the bad part of the outage. Please feel free to start posting messages to rv-list(at)matronics.com as normal! Also, please have a look at the matronics web pages, archive files, and videos and let me know if you have any problems. The URL is: http://www.matronics.com and the anonymous ftp server is:
