Finished it & flew today, it rolled left on take off. Almost wrecked again. Got it trimmed out with lots of right aileron trim. Yes I checked and double checked travel, zeroed sub-trim. I started out with no trim and ailerons centered, before I left the house. Ended up with right aileron up 2mm, left down 2mm, to get her flying without a roll. That's 9 clicks of trim.
I did fly it till storm clouds rolled in. 3 flights, 3 landings.
The only thing I'm happy with is the blue bottom, with white top colors are easy to see.
I guess I will have to learn how to build wings next time business is slow.
