I just had a day of flying on my primary force with a G15 and a 55A Trust esc.
It ran flawless, the battery didn't get warm, the motor was cool on a 3min flight.
The battery used was a 4s 2800, and I had to put 1000mA back in.
I was using a 11x 5.5 at 9650 rpm at 5 sec laps on 58' lines. I have to say I was impressed by the esc and motor. For the price you can't beat them.
