normally one would use say 2 regulators and 2 lipos for instance to power the receiver with one maybe 1600mah battery and then for ignition maybe 1800mah... how about just using one lipo with one regulator and splitting the supply to both the ignition and receiver... like have one 3000mah battery to supply both, can it be done? is there disadvantages? positives maybe? would like input from you guys... I will be using 9001MG PowerHD servos...
