What can I use this system for?

Can this system be used on a plane or is it only good for a heli?

If so, what size and weight of plane?

If you Google Hacker C50 14XL it will come back with quite a few hits. It would seem it's ideal for a larger aerobatic model.

But, most references also refer to using a 6.7:1 planetary gearbox and a 10s pack, and something like a 20" prop.

That and a model could involve quite a big investment.

From a forum comment -

To use the C50-14xl in a pattern plane you must have the planetary geardrive fitted or it will not turn the big props with a 10s battery pack the C50-14xl motor is turnning over 40,000 RPM the planetary geardrive has a reduction of 6.7 to 1 which allows it to turn big props at 6,000+RPM
I have a C50-14xl comp turnning a APC 20x15 at 6500 RPM + drawing 77amps using flightpower 5000 mah 10s1p battery packs
