The difference between Skywalker-40A and Skywalker-40A-UBEC:

SKYWALKER 40A ESC BEC

PN=80060020

Cont./Peak Current: 40A/55A 

Input: 2-3S lipo

BEC Output: 5V,3A(Linear mode)

Program Port: Program/Throttle Wire

SKYWALKER 40A V2 ESC UBEC

PN=80060140

Cont./Peak Current: 40A/60A

Input: lipo 3-4S

BEC Output: 5V,5A(Switch Mode)

Program Port: Program Wire Firmware

Tips: UBEC provides greater output power, which is mainly used in two occasions: with heavy load; The input main voltage exceeds the allowable range of on-board BEC. It is only use when the output voltage of the electric regulator is high or cannot reach the voltage and current required of the servo.
