I just purchased an RCexcel ignition BEC for a .60 sized scale warbird with a DLE 20 installed. Naturally space is a concern along with weight. I have been flying the plane fine with a seperate battery for ignition, but thought it would be nice to eliminate it. I have 8 servos installed and was wondering what the best battery , size would be good for this application. Or if any negative experiences, should I avoid the BEC altogether? I have a DaiPhan 2600mah, 6V battery for RX and servos now.
