I am finishing up a 40 size Wing Mfg P-40b. Had originally planned to fly it with an OS 40 LA and a 10x6 prop. Put her on the scales last night and looks like it will end up at 5 lbs. dry. The engine is mounted upright. She is fiberglassed with PolyC.

Will this be enough motor for this plane? Any and All opinions would be appreciated.


Thanks
Jim
