Hey guys, i recently picked up a Spektrum DX3S, I like it for the fact that it only takes 4 AA batteries. My question is this. I can not seem to find a Transmitter Battery for this model. am i overlooking something? Are there LIPO alternatives? I would much rather use a Lipo pack. Could i just use a NIMH reciever pack? Still would like to use a Lipo, just dont know if 7.4V would work in this transmitter. Thanks
