This motor is great.
I use it with 11 pinion 3260 rpm on T-rex 450 pro. Powerful, isn't hot after 4 minutes.
I flew with it about 70 starts so far. Recomend.
I use Turnigy HeliDrive SK3 Competition Series - 2839-3600kv
on my T-rex 450 pro whit 12 pinion ,3000 main rotor rmp.
I'll buy 4300 Kv SK3 , with 11 pinion, as I count main rotor rmp will be about 3000.
very likely, I used that prop on a 250 class motor (3800kv) for my parkjet and I reached 121.2 mph at 36A, on 3s lipo and it survived, I now have a 450 motor (3550kv) with a 5x5 on it, stationary test gave 68A, on 3s, just waiting for spring to test it out :)
