The plans (page 21-05, step 3) call for the aft edges of the FL-00001 nose skins to be crimped. Nothing is mentioned about crimping the FL-00002A and FL-00002B top and bottom flap skins. I am wondering if I should crimp the aft edges of the top and bottom skins. The last time I recall using this type of trailing edge material was the rudder, which (page 07-07, step 5) does call for a "slight break" on the skins. Does anyone have experience with the flap trailing edges with or without the crimp?
