The ailerons are even on the ground, but I can see them out of trail (right turn) when I let go of the stick. Is this the infamous "Heavy-Wing"? Any other ideas? Thanks, Ralph Sent using myEarthLink ________________________________ Message 2 _____________________________________ Time: 09:27:40 AM PST US From: Gary VanRemortel Subject: Re: RV-List: Right roll tendency Gotta be something far out on the wing, maybe wing tip.

It's been several years since I replied on the list, so I don't know who will get this. Regarding mysterious roll and/or yaw tendencies, always remember to consider the possibility that imperfect adjustment main gear leg fairings can produce imbalances in the aerodynamics of an RV aircraft. I'm just sayin'..... ALSO, does anyone have experience with the installation of a single or two axis autopilot in an RV-3. I am ready to buy one that has no A/P. I installed one in my RV-4 25 years and would not want to be without one now that I'm 82 yo. Has anyone installed a servo under the seat or anywhere other than in the wing/wingtip?

Van has a system, using twin e, to adjust the geometry of the fairings to a uniform, neutral, and aero dynamic position. I would check the current geometry using this system. I f this is off, make the necessary adjustments. If this is correct, would make a tiny adjustment in one or the other to give A bit of yaw to the ri ght. I would probably twist the trailing edge of the right gear leg 1/8 t o 1/4 inch towards the left( towards the fuselage). If I=99m wrong about the direction to make the twist, you will know right away. I have n ow exhausted all of my knowledge on this subject. Please wait for replies to my advice. I could be way off base on the core to your problem. I =99m basing my thoughts on the results of a bird strike to my gear leg fa iring after 10 hours of TT. I fixed the fairing and eyeballed the proper twist. I had a heavy wing thereafter and did the pinching to aeleron as s uggested by some. I even made a temp trim tab. Nothing worked, until the light went on in my head about the importance of proper setting of the fa irings. A little twist solved the problems. I then made some permanent ma rks on the gear leg and fairing so that I could always replace them prope rly after my conditional inspection. I hope I didn=99t create firew orks. Good luck.

I made myself a breakout cable to monitor the signals/voltages on the sensor lines during flight. The 10VDC was dropping out, so I took the DPU apart and traced the supply path to VR2 on the analog PCB. I reasoned that since this 10VDC only powered the ammeter circuit, it must be flakey. I replaced it (TI 78L10AC) and now all is well. -GV ________________________________ Message 8 _____________________________________ Time: 04:27:42 PM PST US From: recapen@earthlink.net Subject: RV-List: Re: RV6-List: VM1000 AMP/Current circuit Good job Gary!
