What ratio gearbox?
I want to spin one of the 3-blade props provided with the Flying Styro Kits on a SPEED 400. What ratio gearbox would be able to handle it? I had a 7.7:1 gearbox for a SPEED 300 that spun the same prop. As far as I have seen, there are no gearboxes of that ratio for the SPEED 400s. Any help will be greatly appreciated.

RE: What ratio gearbox?
A GWS I-gearbox for Speed 400 is 6.33:1 - would that do it? I don't know what the diameter and pitch of that Flying Styro prop is - if I did I'd run it through Motocalc to see what it came up with.
