I searched the archives and got some good tips on using oops rivets to install the platenuts. My question. Once the platenut is installed, do you countersink the reinforcement plate to accept the dimple from the cover plate? The only other option would be to dimple the reinforcement plate and countersink the screw hole inthe nutplate. Which would be the best approach? Does it matter? ________________________________ Message 5 _____________________________________ Time: 12:59:13 PM PST US From: bertrv6@highstream.net Subject: Re: RV-List: how to feed the battery cable through the firewall?? --> RV-List message posted by: bertrv6@highstream.net Quoting Gert : > --> RV-List message posted by: Gert > > > Hi folks > > For those of you with the battery not in the engine compartment. > How have you brought the wire from the battery to the starter contactor > through the firewall?? > > what kind of penetration/insulation/chafing prevention have you used. > pro's/con's?? > > thanks Gert: plans for rv6a, is to be installed inside fire wall, that is the starter and Battery contactor...you must have different model,no?

I bought some VG's from Greg H. (the Larry Vetterman brand, 1999 model, RV-4, ones). The adhesive had gone south, so I epoxyed them on. The results I'm listing at this moment are from memory and are in MPH not Nuts (knots). I have an RV-4 IO-320 inverted fuel & oil, 160 hp, fixed pitch prop (I bought from Rob R., waiting for my new prop to get final finishing done) with 80% span ailerons and 18 inches of "Airbrakes" on each wing (aerobatic reasons, or so I like to think) and no wheel pants or gear leg fairings on. Testing was done at 3500' on two 85 degree (zip for humidity) mornings each time. Turning stall testing not completed yet; but roll authority has a noticable improvement/responsiveness. *Prior to installation: >Power-off Clean stall - 54/55 >Power-on (2300 rpm) Clean stall - 50/50 >Power-off Airbrakes - 53/53 >Power-on Airbrakes - 51/50 *After installation: >Power-off Clean stall - 49/49 >Power-on (2300 rpm) Clean stall - 43/44 >Power-off Airbrakes - 49/49 >Power-on Airbrakes - 43/43 ***note the Power-on Airbrakes stall "Helicoptering" at 43 mph ? Just kinda hanging there on the prop. My opinion so far, with no side-by-side RV-4 testing yet (maybe if/when Scott V. comes by again), ...but I wouldn't spend the money again, HOWEVER... I ain't gonna take them off now neither! Chuck Jerry2DT@aol.com wrote: --> RV-List message posted by: Jerry2DT@aol.com Hi Joa... Your product looks intriguing and the price seems right for sure.

For those of you who live out in the flat lands, the bumps out west are really a lot of fun on a pretty white and blue day. Day one after work was from San Diego to Agua Dulce for their Friday night steak dinner, burp, then on to Columbia Airport for a early night quick camp. The next morning I popped from there to Aurora direct, hung out for half the day then decided the clouds looked like they wouldn't be fun to camp under over at Vernonia, so headed back south to Shellville in the Bay Area to visit some friends. Had a great time there, met some folks who are major old timers in aviation. This airport is where the OSH show stopper Curtiss Jenny lives. From there I followed the coast back down to Santa Paula, then over to Auga Dulce for a soda and more low cost fuel, and then on home. For those of you in the SoCal area this airport has recently come under citizen attack, and they are looking for a few good signatures. So stop on in every chance you get. I don't have much to report on the home coming event other than there were a lot of aircraft showing up as I was leaving. I got a few pics and will try to post them via Matt's photoshare as soon as I catch up on a few other projects. W PS Hi Mikey, how's the flying out there in the middle these days? ________________________________ Message 8 _____________________________________ Time: 05:27:08 PM PST US Subject: RV-List: Dynon D-10 errors From: "Stewart, Michael (ISS Atlanta)" --> RV-List message posted by: "Stewart, Michael (ISS Atlanta)" I want to thank those who have inquired as to the errors I have been getting on the Dynon based on some Findings From Dan Checkoway's post on his website here: http://www.rvproject.com/20040901.html Dan has done an excellent good job summarizing the issue there. I suggest you read that first. To summarize, myself and others, have been getting errors on the horizon function of the Dynon EFIS. In one case it really scared me and as a result I have grounded me 6A from any IFR work. Most of the errors are a lean in the roll axis by as much as 7-10 degrees. Pitch errors in my case have been as much as 20 degrees. Here is a brief synopsis of what and how it is happening based on some e-mail to Dynon: I flew 6 hours today and worked the Dynon hard. I can now easily reproduce the lean. I started after departure at 2500rm and went to 1900rmp 10rpm at a time with 1 minute intervals, and back to 2700rpm At 2560, the leaning happens, it slowly oscillates from right to left, and back again. I can come off it by 15rmp on either side and it resumes accurate operation. I can give you further details but I now can quickly reproduce it, and I took some shots of how bad it is out on the lean. You will notice that on one shot, the bank indicator on the right shows wings completely level, autopilot on, and it was silky smooth air. Also I have seen it at other RPMs today. I saw it in formation at 2480 but could not troubleshoot as we were practicing. I was able to see the pitch out during this activity, but not by much. 2 degrees maybe, but it was out and I could watch it happen with the leaning at the same rpm, although the pitch was not as reproducible as the roll problem. took off from home base, early turn out, climb in smooth morning air to 3500'agl level off and the d10 compass heading was swinging a d10 being erratic on the screen. That caught my eye. At the same time, d10 showed me in a 20 degree climb and I was level. In about 6 seconds the compass stabilized, and in about 20 seconds the pitch stabilized to level. Next on a different day, I saw another example of the leans in roll information by about 4 degrees. A very pronounced lean showing a right hand turn 4 degrees or so, autopilot flying the plane straight and level, compass on the d10 holding steady. It would eventually, after 1 minute or so get level, then lean again. This went on for about 6 minutes. Then fine. I have seen this behavior in the unit a dozen times over the 700 hours of flight with it. In another case, the one that really scared me, I came out of 15,000' on a long hard decent to 1000'AGL and leveled off in MVFR vis 2, mist, and the dynon showed I was in a steady climb of 20 degrees. I was clearly level cross checking other instruments and was low. After a min or so it cleared up and resumed normal operation. This is the largest deviation in pitch I have seen. I took a big deep breath and thanked god I was not IMC. If I were, I may not have caught the pitch error and might have put the nose into the ground. Needless to say, no more IFR till it is resolved. So the above e-mail excerpts will give you and idea of the issue. Like Dan stated on his webpage, I have been in contact with Dynon and they are taking this very seriously. I have been impressed with their responsiveness and professionalism. Clearly this is serious and Dynon says "this is the most important item on their plate." Now, we have not found a fix yet. I seem to be the only guy who can easily reproduce the problem, but I would bet, as I did with the EMI item, that this is a fleet wide problem. Dynon says I have the most hours on their unit in the field. Perhaps that explains some of why I have been able to get to a reproducible stage. They are working hard and I am confident they will get to the bottom of it. They have offered to refund my money. I haven't taken it yet as I want to help them work out the problem. This is a terrific unit and I am confident they will nail it down. Until then, remember this is an experimental device and should be treated as such. If you have one of these in your plane, keep this in mind as you fly. Picture of a lean here: Notice bottom right Trio Autopilot shows wings level, as they were. http://www.mstewart.net/deletesoon/dynonlean.jpg Regards, Mike Stewart ________________________________ Message 9 _____________________________________ Time: 06:51:51 PM PST US From: "Doug Rozendaal" Subject: Re: RV-List: Dynon D-10 errors --> RV-List message posted by: "Doug Rozendaal" Mike, I have occasionally seen the roll error from the get go on my D-10. I never dreamed it was RPM related. Mine has been really good lately and I was not so concerned about it any more, but now it all makes sense. The only times I have problems lately is early in the flight (read climb power) I used to run higher RPMs and I had more problems. I have been using 2300 much more than 2400 or 2500 I would go test this right now, except, I was showing my Dynon to a vistor and I did not get it shut down, it ran the Battery down on the airplane and When I charged the battery back up, it would not fire up so mine is back at the factory getting looked at. I have NEVER had a pitch problem with mine, just the ~ 5 deg roll issue you describe. I have a very early D-10 and I have about 235 hours on flight time with it.

Let's say this "friend" is pulling his hair out because I - uh, *he* cannot trim his plane out to straight and level flight without some control input. With the wings held level by the stick in straight and level flight the plane wants to go into a skidding left turn. To keep the plane on a straight course the stick either has to be deflected to the right or right rudder/left stick must be held. There is already a trim tab on the rudder. Should I just keep enlarging it? > Nah, big tabs are draggy and look bad (IMHO) > Any other ideas? > Well, yes. I'm not familiar with the RV rudder setup so I'll offer some things: If you don't have rudder springs between the pedals and the firewall (springs to put tension on the cables) then this addition would be a start. What you can do (if you have the springs) is to twist/untwist the cables to change their effective length, which will set the position of the rudder to one side (to counteract a skidding tendency). I do not like trim tabs ..... so I spend a lot of time on rigging and tweaking stuff instead of bending tabs that add drag. Good luck!

After reading all the emails, it was easier than I expected and turned out very well. Maybe I was just lucky, but here's what I did: 1- I used a lot of talcum powder on everything including the the wheel rim and tire bead. I put one wheel half on the tire (with the deflated tube) and used a wooden slat and a plastic mallet to push/pound the bead further onto the wheel. It helps to have two people to hold all this down while wacking it. The second wheel half is not in place yet so you can easily reach the bead from the inside of the tire. 2- With the tire bead most of the way onto the first wheel half, it was easy to get the second one close enough get the nuts started on the bolts. Just screw them on part way, though. The two wheel halves are now separated by a gap of about a 1/16". You can see the gap all the way around using a dental mirror in the center of the wheel. Look into it past a trouble light held against your face. A flashlight might work too. You can see if the tube is in between the two wheel halves at any point. In my case it appeared to be pinched at one place. 3- Next, I put about 5-10 pounds of air in the tube. My theory was this partial inflation makes it harder for the tube to get caught in the gap between the two wheel halves. It "rounds out" the tube and that makes it harder to pinch. At least visual inspection indicated it was not caught in the gap after I did this. 4- Tighten down the bolts by turning each nut 1 turn in succession. 5- Inflate the tube and deflate it several times just as they say in the manual. Since there's no weight on the tire, I think it can be over inflated safely to the 50 - 55 pound area, which is what I did. This made the tire beads slide nicely out to the rims of the wheel. It appears to be mounted perfectly. Maybe I just had a fortuitous fit here, but I think it was the talc on the wheel and the tire bead that made it slide into place. -- Tom Sargent, RV-6A, Landing gear
