I called BME and the guy said that Arfs are sometimes 1/2" off just make sure the tail is even with the wings[sm=angry.gif] I tried that and my stab is so crooked that it is phisically noticeable. The fillets will not go in one side its so crooked and the other there is a BIG gap..the meaurements from elevator to the stab reveal that it is a 1/2" difference.. also under further inspection it looks like its the fuse that is crooked and it was that way when they cut the slot for the tail because that is crooked too.. so far there is only 1 step in the instructions where i did not have to do major mods.. my belly pan mated right up and matched the fuse. but the plane with the crookedness looks terrible... I am waiting on a reply from an E-mail from BME to see if they are going to take it back or am i just going to have to use this thing for firewood... I am not flying a plane that has a 1/2 inch warp in the fuse. i am pulling the servos out of the ailerons and throwing in the towel on this one[&o]
