RE: GP Super Stearman
Tailwheel:
Mine balanced right on with no weight ... my brother did his PT17 same engine and smoke as mine and his balanced right on with no weight. If you use 5 1/2" instead of 5" for your CG you might be able to take out the remaining weight that you have in it. Is there some reason you used 5" instead of 5 1/2" ?
