RC Flying: How to install a UBEC to power only the retracts.

Here is a quick video showing how to wire in a UBEC to your RC power setup. A UBEC provides you with a second source of power that you can use to power certain servos, etc, like retracts or flaps. Once you start flying large aircraft, ie: over 1,500mm that use larger servos. The SBEC in the ESC may not have enough amps to provide adequate power to all the servos if all the servos are in use at one time. Providing the retracts and flap servos with their own power supply, ensures that the other servos connected to the receiver will always have adequate power. As always, do your own research.
