A friend is getting out of the hobby and gave me midwest AT-6 Texan with robart retracts and a us engine 41cc this is my first gas engine and first warbird trainer I was wondering about the At-6 and the us engine.I alot of exprince with robart retracts the engine is new and so is the plane still in box. Any help would be much appicated jimmy

The US 41 is far too large for the plane. The Midwest Texan should use a 1.20-1.50 fourstroke.
