Just in case it hasn't been mentioned read the manual!!!! also while reading it look at the plans so you get familiar with each part of the plane as shown in the manual, oh and read the manual. The LT-40 is a sweetheart to build, done 4 all ready, kept one and the others were sold. Now enjoy yourself and if you want to see a lot of kit come and look at my 1/4 scale super Cub!!!!![X(][X(][X(]
