Crazy that something the size of a stirring straw could have an affect. If I do end up needing a wedge (Which I would rather do than remounting the aileron hinge point), where have most people sourced these from?

Default Rudder?

Just a shot in the dark here but is it possible that the rudder isn't rigged correctly? I have no experience to back up my thought here so take it for what cost you = <1Cent.

I used a small balsa piece that was pre-shaped into an aileron shape from the hobby store. Once sized, I put a coat of paint to seal it and then used silicone to adhere to the rudder and the under side of the aileron on my 6.

So thatís for a rudder, would something like that work for an aileron too?

Crappy weather so still havenít flown. Also with my rerig my wingtips are only about 1/8Ē off or so. So at this point might not be worth the hassle to split them for cosmetic stuff

Rudders and ailerons and aerodynamically equivalent, they just operate on different axis'

Any explanation for why rotating the gear leg fairings clockwise viewed from above wouldn't cause the plane to bank to the left (and also yaw left) even more? I'm having a hard time imagining that this brings about the effect needed to correct a left roll and left yaw. What's the aerodynamic explanation?
Bill my view is that the gear fairings are acting like small rudders ahead of the center of pressure. So they act in reverse. Please note that I have said that you should fix yaw first as in getting the ball in the center before moving on to fix the roll problem.

Just to close out the thread. I've put on 7 or so hours of flying since I made all my adjustments. I STILL have heavy wing, however it seems to be better since AP can now handle turning right with no issues (used to have to help it some at 100% torque, now I have it at 80% and it's fine.)

I flew the other day and got to 5 gallons remaining on the left tank, right tank was full with 30 gallons. Even then I still had a slightly heavy left wing.

I'll keep fiddling with it but I guess not planning on splitting the wing anymore.

Okay here was how I resolved the heavy left wing issue. It took a number of test flights as I would make a change, fill the plane up, go fly...

I had fiddled with the ailerons enough that it was time to mess with the flaps. I could only measure them so many times with a digital level and then I just decided to make some adjustments. It's hard to accurately measure these on the ground because there's some play that gets removed by the air pressure in flight. I tried to simulate this by pulling up on the flaps but then maybe I'm pulling up too hard, or maybe not enough.

First thing I did was bring the right one up by a turn and a half of the rod end. This had a noticeable effect, but it wasn't near enough to resolve it. I did two adjustments on the left one, first I did a turn and a half and then later another full turn. This took out most of the heavy wing but it was still heavy and I couldn't remove it with the aileron trim.

I ordered a wedge from Cleaveland Tools and taped that under my right aileron after a fill up. Went and flew for an hour and a half and noticed practically all the heavy wing was gone. For the first time I was able to trim it out when I had a few gallons out of the left wing.

The last thing I did, which started this post was split the wingtip and reglass it even with the flap and aileron position. I did more than split it I had to drill out the rivets for the triangle piece, redrill new holes and re re-rivet. I also had to do a bit more fiberglass work because my cuts to split it weren't the best. Either way I got through and went flying.

ALL my heavy left wing is gone. With two people in the front I'm able to trim the plane out both in pitch and bank and fly no handed, with autopilot off. So in the end it seems that a combination of flap, aileron adjustments, a wedge and the wingtip splitting were needed in my case.

Probably a good idea to disconnect your aileron trim springs while troubleshooting the heavy wing. Otherwise, the spring tension is masking the roll forces on the stick.

Congrats on SUCCESS! I too had lots of little things. Doing the big one first really removes the masking of the smaller improvements.
