Electric free flight motor

I can't help myself. I ripped apart a cute little free flight cub to see what the motor was. The magnets are strong, there is some cogging. It pulls 5 amps from this 4 inch prop with only 2 180mah nicads!

Would this motor be of use in a gearbox for something more R/C like? Or should I just stick it back into the free flight model and go fly?

5 Amp?

I wouldent use it in an RC plane, put it back in the cub and go fly

Good luck!

I say put a much smaller prop to see if you can cut the current down?

I think this motor is heavily overpropped, but it might be a good motor when it can turn a bit faster. Give it a good amount of gearfactor, say 5:1, and choose a prop so that it pulls 2A from 4 cells, and it might be a winner.

BTW, the cogging can be a sign of a strong magnet (which is good) or big gaps in the rotor (which are bad).

Looks and sounds similar to the Cox Motor I pulled out of the Higway Patrol, and replaced with an N-20 Geared on 4x120 cells.

Even on a 5:1 gearbox and 6" prop from a rubber powered model it draws too many amps and doesn't blow as much wind as a GWS IPS. Oh well, guess I'll keep it for free flight.
