I just purchased this receiver and did my first flights today. Aircraft is a 50cc sbach with futaba s9155 servos and two new spectrum 2700mh receiver packs. also the da50 ignition is routed through the receiver. After two ten minute flights I was showing a alarming amount of battery loss servos were gitting jittery and my volt watch was dropping into the red when three servos were used at once. so am I using to small of battery packs? do I need to put the ignition on its own battery? I had thought that two 2700mh packs would be plenty for four flights.
