The PowerExpander Competition 12 can be used with any size aircraft. It will work with any receiver with any number of channels. 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. This unit is the same as the PowerExpander Competition 12 Plus but has none of the Fiber-optic Ignition Cutoff capability.
