I found 1/3 scale GTM DR1 to fly very well and stable. In fact I have a Balsa USA 1/3 sopwith pup and the DR1 flies so much better. The problem is landing and its a big one. Fortunately you have grass to land on but black top you would have broke the prop scratched the cowl and sanded down the wing tips to a pulp. Anyone thinking of flying this plane on black top runways should think otherwise. Nice plane good power. BTW what servo did you use that got striped?
