Castle Creations 20A (peak) Switching BEC - 010-0004-01

The Castle BEC Pro is a staple for RC jets and prop planes running high voltage LiPo packs.

This will ensure you have plenty of power for your servos, retracts, receiver, lights, and other accessories. A Proper setup using this Castle 20A BEC will help prevent brown outs which some popular receiver brands are prone to. The BEC includes two wires with JR connectors to connect to the receiver and bare wires on the other side. Please see diagram or instructions for proper connection.
