Finally have this Ju52 finished. When using the UBEC as suggested should i use only one (3 cell) lipo to power the entire system? Taking this a step at a time with all the esc's hooked up with Y harnesses to the UBEC i plugged in one lipo and all three esc's had power to them. I don't want to try plugging in additional batteries in fear of damaging some of the electronics.
