The Ignition Regulator is designed for use with lithium batteries and electronic ignitions. The Ignition Regulator has a fixed 5.2V output and has a current capability of 3A continuous. The regulator has a large output capacitor to handle the peak currents required by an electronic ignition. The regulator has universal connectors with 22-gauge wire.

The Pattern Regulator is designed for a 2 meter pattern plane or
smaller. Do not use this for 3D flying. The Pattern Regulator has a
fixed 6.0V output and has a current capability of 3A continuous. The
regulator has a large output capacitor to handle the peak currents
required by an electronic ignition. The regulator has universal
connectors with 22-gauge wire.

The Servo Regulator is designed for use when a PowerExpander is
being run at 2S lithium battery voltage but you need a lower voltage
for a servo voltage. The Servo Regulator has a fixed 5.2V output and
has a current capability of 3A continuous. The regulator has a large
output capacitor to handle the peak currents required by digital servos.
The regulator has universal connectors with 22-gauge wire.
