Thanks for tip on landing! Will try that!. I used lots of CA and epoxy strengthning the structure. covered firewall as well as the wing servo tray area with thinned epoxy.
Had tough time setting up the aileron servo rods. Decided to keep the rods square to aileron (manual didn't mention this), but the tray doesn't seem to have much area to do that easily. In retrospect I think it wouldn't matter if you don't keep the rods square to aileron.

I have couple of top flite 11X6 wood props spare. Will it make some difference in performance if I use them instead of APC?
