i added another piece of hard wood to the fuse doubler for the landing gear mount.i might go with two aileron servos also,i have another wind kit for this model.i had a problem with the wing jig,i set up everything like was said and had weights on the wing halves during the epoxy set up but when i removed everything the wing came up a little higher on one side than was called for they stated no more than 1/16,it came out almost 1/8 difference guess a little sanding on the wing saddles wont hurt much
