The 3-cell E-flite 3200mAh pack and 4-cell ThunderPower Pro Power 30C 3300mAh pack are shown in their positions to obtain the balance recommended in the manual. For less than a 3oz weight penalty, and some additional cost, you can more than double your power by using a 4-cell pack. This upgrade should really make the BAe Hawk perform well.

Since the E-flite 60-amp Pro Brushless ESC has a fail-safe switch design, I find it easiest on these smaller models to simply cut off the switch and get it out of the way. I cut one wire slightly shorter and then cover the ends with a small piece of shrink tubing.

I measured the power level of each pack as follows. The E-flite 60-amp Pro Brushless ESC can handle 75-amps peak so it will still be within specs on your high-speed passes at full throttle.[ul][*] 3-cell pack, 360 watts, 36 amps[*] 4-cell pack, 900 watts, 64 amps[/ul]
