First a little background. 1982 Bensen Gyroglider kit. The engine is supposed to be an 83 Great Plains 1835. 1985 Ken Brock VW conversion kit.
Does anyone recognize this prop hub? I don't see it available from Great Plains. Linda at Okeefe Aero (the original owners of Great Plains) thinks it's a HAPI. My main concern is what torque value to torque the hub bolt onto the crankshaft. Secondary concern is why does my GP VW have a HAPI prop hub?
Next question: Tennessee Propellers suggests a 52X28 for a 1800cc VW on a Gyro. The prop that came with the engine is a Brock 50X20. Any of you guys running a 50X20 on your VW? If not, what are you running?
I look forward to your expertise.
