I have two identical SmartFly pattern voltage regulators for sale. Super reliable and in excellent condition.
The wires on one of the units have been shortened to save weight.
The price is for one regulator.
From SmartFly website:
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.
To maintain a 6.0V output the battery voltage must stay above 7.0V. A battery voltage below this will result in an output voltage of the battery voltage minus 1.0V (i.e. for 6.6V battery voltage output will be 5.6V)
