soothstone Posted July 18, 2013 Report Share Posted July 18, 2013 Developing electric conversion for Limbach powered RF5B. Powerplant is nearing ground testing phase. Looking for a prop suited to a Limbach Hoffman flange (6 holes on 80mm centers) for use during the ground testing period. I am mounting firewall forward, including facsimile cowling, on a ground vehicle to test dynamic air flows, thermal conditions at Vx, Vy speeds etc. and the prop would be used for this purpose, not flown.Eventually, (presuming successful ground tests...) I will install my Hoffman 3-position prop for flight tests, but I would prefer to keep it flying in the meantime!Thanks for any suggestions.Douglas Quote Link to comment Share on other sites More sharing options...
