RE: wing warp?
funny, Mine has about 6 clicks of right aileron...
I found a warp in the tail after my first couple of flights, I straightened it out but it still requires about 3mm deflection on the ailerons towards the right.
Who knows? it seems to track pretty good and vertical is vertical. Did everybosy use the supplied side/down thrust blocks for the engine mount? I did and I haven't had to adjust anything else apart from a couple of clicks of down elevator trim and a few right aileron.
