Commonly called a UBEC or SBEC, this device eliminates the need for a built-in BEC in your speed controller (ESC) or can replace a built-in linear BEC that may not be capable of handling high servo loads. External BECs are recommended in larger electric models running multiple or large servos. Supplying a constant 5.0V+ power to your receiver, UBEC's help eliminate the chance that "power hungry" servos or accessories will draw the supplied voltage down below your receiver's minimum shut-down point. Our BECs are manufactured by Suppo, a trusted name in the RC electronics industry.
