Voltage Regulators

Do I need an Voltage regulator/BEC?

If you are running a gas plane and would like to use one of your li-poly batteries to power your servos. The VR-3 would connect between the battery and your receiver and can run up to 8 standard servos.

You are running an electric plane and your ESC does not have a BEC built in, or it is too small. In this case you can wire the VR-3 in to the receiver to provide adequate power to your micro servos.

You want MORE POWER or SPEED from your servos. Most ESC provide 4.8~5.0V to the receiver for the servos. If you plug in the VR-3, your servos can run at 6.0V which produces more torque and faster response!
