I recently found a crack in one of the blade collars of my 68 inch 3 blade Warp Drive taper tip propeller!
It is turned by a Franklin 4A-235-B31 motor producing 116 Hp @ 2800 RPM
It can run Max continuous power at 2800 RPM, but I generally run it at about 2350 rpm
The Static RPM at my 4000 ft was between 2300 and 2350 depending on the temperatures outside.
I cruised at about 95kts Indicated.
This is all on a Kitfox 5 at Max all-up weight of 703 kg.
Now:
I have the possibility of buying a 3 blade DUC Swirl carbon prop second hand.
Can this prop be used in my set-up?
Many Thanks.
