I finished an LT kit early this year after stopping work for a year due to thinking that I had warped one wing and also sanded too much and in the wrong places. I finally finished it and it flies great. I only wished that I had pushed on w/o worry and enjoyed the end product, it is one fine trainer. Heck I just crashed first time and never even blinked as I picked up the rudder and motor laying 50 yards from the fus. It even flies again warts and all. Don't fall in love with your handiwork, it is made to be used. Do however reinforce the area of attachment for the rudder. It is weak as you will see when you get there.
