Great idea.
What kind of control servo did you use and how did you route the wires ?

Default Flaperon trim servo

It's a Fergelli L12-30-210-12-5 RC model linear actuator. Plug and Play in place of a MAC or Ray Allen servo
Very light. I threw it up to see if it would come back down, but it floated all around the hangar - Had to get a ladder to retrieve it!

Default Flaperon servo wiring

I ran the wires out the inboard end of the flaperon, then up the hinge bracket and into the wing between the first and second ribs. A molex connector is used at the wing root to connect to the Garmin roll servo, just like the pitch trim is connected to the pitch servo. I installed a Tosten stick grip with coolie hat trims and a relay deck to handle everything. The way it's wired, both the panel mounted pitch trim and the coolie hat pitch trim are operational.

Caveat! you may want to add a bit of weight to rebalance the flaperon before flight, especially if you have the added weight of paint, which I don't.

Default Very nice!

Very nice Dick. Have you flown with it? If so, is there any issue going from a cruise condition to a full flap condition? I have always had a heavy right wing and I've tried all the squeezing and pounding methods on the flaparons to correct it to no avail. This looks very interesting. I would be very nervous in cutting the hole though...

Is your plane at an airport? I live in Paris, TX and might stop in if possible some day.

Thanks

Smile Flaperon trim servo

I had an uncurable heavy wing when I detcided to do this. I had installed a fixed trim tab, but it was out of trim again when i deployed flaps! This solved both problems and i love flying with it.
I'm based in Georgetown TX...Visitors welcome!

Check the top wing skin where it overhangs the aft spar just in front of the flaperon. My experience with adjusting the flaperons was similar to yours but I found that bending the aft edge of the wing skin up or down slightly made a noticeable difference to the trim.

Default Check the wing skins aft of the rear spar

A second vote for checking the wing skins aft of the rear spar. Leveling this area on both wings cured my heavy left wing.

Read about it here my post is #5:

Happy flying,

Default I'll try it!

Thanks Robert and John for your suggestion about the wing skin aft of the rear spar. I'll work on the heavy wing today and hopefully go flying in a couple of days to test. I will report back to results.

Steve -

I would suggest checking both wings and not just the heavy wing ... both of my wings needed some tweaking.
