Run it on 4S and it will get even hotter.

C rating is the 'burst' capacity (it can handle 20 times the current for a very short burst) 'S' is the number of cells (and each cell is about 3.5 volts)
I don't care what it says on the profile - I'm so NOT GB!

that's why i was asking if i could run it on 3s 2200mah 45-90c instead of a 3s 2200mah 20c.. would it make much difference?

Using a battery of a higher "C" raiting will have lower voltage sag when used hard, so the voltage will stay higher for longer.

I used a Turnigy Typhoon 450H 2215H Heli Motor 3550kv and a 5x4 prop on a eurofighter and it lasted about 6 flights before burning out the windings, so I rewound it with a thicker wire and higher KV. After launching it WOT it screeeeeeemed for 10 seconds before letting out the magic white smoke form the ESC...LOL... it was good fun while it lasted :D

It is .25" more pitch speed than the one you suggested, so the plane should still be plenty fast.


If i was to use a 4s with a 5x5 prop would i be pushing it using the motor and ESC i listed?
