Ken: The stock landing gear supplied with the kit did not agree with the prints. No real problem, just had to know which way to go. A piece in the vertical fin was cut wrong. In my opinion, the horizontal stab. is too light and fragile, especially at the joints with the ribs. This was componded when some of the balsa for it was brittle. Should have gotten a new piece from Sig, but made the decision to just reinforce the joints with gussets. No provisions for an antenna tube. This is an easy one to forget.. Again don't get me wrong, it is a very good kit and I would buy it again. .. Fred123[&:]
