All my Norvel .049 and .061 planes have been profiles with side mounted engines. never an engine run problem.
Want to build a 1/2 A full bodied stunter, ie Pathfinder, Stiletto type or ?? , w/ upright or inverted Norvel engine.
Question: Looking for comments re. good or bad experience with upright or inverted Norvel engine in a stunt plane.
Thanks,
Roger Vizioli
