Getting ready to fly a new foamie (e-foamie Revolution 3D), with the recommended AXI 2212/26 motor, Phoenix-25 ESC, Kokam 3C 1500mah battery, and using the recommended props of either a 12x3.8 or 11x4.7 the current draw at max throttle drops the battery voltage to hit the 9V cutoff when testing it just holding the airplane in position. I've monitored the voltage with a DVM and it is hitting the 9V mark with the 1500mah batteries, but a 4200mah holds up (but is too big for this airplane). Haven't tried a amp meter yet, as I don't have anything that goes over 10a. Has anyone experimented with the current difference between loading it down in a stationary position vs. what might be expected in flight???
TIA
Don
