Hi,
Re: Earlier thread : The unit draws a max current up to 0.32A, which for a 10min flight is only ~50mAh.
My experience: I had one cell go on a 2 cell A123 1100Mah battery (6.6v) in the air. This dropped the voltage to around 4.2v. The engine stopped and the radio went into low voltage thr low failsafe. I was able to land the plane no problem at that voltage. I just switched the Rx pack and continued flying. However it looks like below 4.8 the ignition will stop first and if you continue the Rx would be next ?
