I guess I was skeptical at first so I tried it on a test plane and it worked...for me...so as I built new planes, the single battery and Tech-Aero IBEC is all I use. In fact, I don't even use a mechanical switch for the ignition...just the IBEC plugged into the receiver. That's just MY experience...others may have experienced less than wonderful results...
