Hey now,
The little Hacker motor isn't going to work wqell in this set up. I had one and running it with a simular set up, I burned the motor up very quickly.
7 to 10 amps is the max for this, thirty seconds of 18 amps *will* fry the windings.
Get either the Himax or E-flite motor 2015-4100 Himax = 4100 E-flite motor, 2025- 4200 Himax = Eflite 4200 motor. I'm using a himax 2025 4200 with the stock E-flite box with a APC 12-6 sf, and drawing around twelve amps full tic. This is more power than you'll ever need.
The Hacker motor is pretty, but I'm very disapointed with it...
