Doc,

I fly with the very same set up and have for over a year. 2600 Fromco, Jaccio reg, But, I power the ignition from an unused port in the rx board. When you run through a additional connection, i.e. Y harness there will be an addtional voltage drop. Since the engine quit first then lock out it sure smells like low battery voltage.

Current draw on the ignition is about 300-350ma at 7500 rpm and is about 50-75ma at idle.

I would suggest a higher amperage regulator to be on the safe side. A dedicated battery for the ignition might be in order for anyone not comfortable with drawing out of the rx power supply.
