bignos Posted November 4, 2009 Share Posted November 4, 2009 Does anyone know a technical way to select a prop size, from what i can gather you need the motor to run at its peak power, then through a reduction to the prop. But how do you know what size reduction and prop pitch? there must be a calculation somewhere??!! Quote Link to comment Share on other sites More sharing options...
dantheman Posted November 4, 2009 Share Posted November 4, 2009 While I can't answer your question, if you want a classic prop to hang on your wall check out this ad that I just spotted: WW1 SE5A prop I reckon a Flat Top would spin that up nicely Quote Link to comment Share on other sites More sharing options...
