The PowerExpander Competition 12 can be used with any size aircraft. It is primarily designed to work with the Futaba and JR 12-channel radios but any receiver with any number of channels can be used with the unit. It supports an optional failsafe switch which enables or disables both batteries. It can be used with 2-cell lithium packs if your servos can take the voltage. It has a dedicated 5.0V, 1 amp regulator for the receiver. The unit also boosts the servo control voltage to 5V for compatibility with all servos. The unit also features a built-in Ignition Cutoff but is sold without the Cutoff Receiver and Fiber-optic cable for jet applications.
