Hi. If you do the math, you might not be too happy with the heat dissipation of the device you are proposing. (About 4.8 watts). Besides, it does waste power that you might otherwise use. An ESC does a great job of translating the battery power to the motor without the attendant losses in a linear circuit. What this means is that if you keep the throttle down, the 3 cell approach will do nicely, except that the stock motor really can't take too much overage for too long. A good idea would be to hook up the 3 cells and put a voltmeter across the motor. Advance the throttle until the voltage reads the maximum that you are willing to subject your motor to. Then note the throttle stick position. Keep you throttle at or below this point in flight and you will be fine. You can probably cheat a little because of reduced load/improved cooling in flight, along with battery voltage sag during discharge.

Regards,
