RE: GP Super Stearman
I got my first flight 3 weeks ago in a very windy day but it flies very good.
I also installed the showtime smoke system with os 120 with slimline pitts muffler and test it on the ground but doesn't seem to burn it ,i don't know what else to do ,and i tried to slow down the flow but not much better. the engine alone smoke more. Well we'll see next time in the air if it makes a difference.
