This is the world`s first 4 in 1 25A high performance brushless ESC--Skywalker Quattro 25Ax4-UBEC, this ESC is

suitable for all quad multirotor aircraft, and four-motor

airplane or four-propeller ship model. Integrated design can not only offer better consistency, but also simplify wiring complexity, so as to improve work reliability. MultiRotor Flying has been very popular as a new generation of RC model aircraft, which is a simple structure, light weight and easy to fly. However, as there are four motors in the four corners, normally there are four ESCs to control each motor, which is complicated to assemble and set up.

The SkyWalker-Quattro-25A ESC combines four 25A ESCs together, useable with 2~4 LiPo cell packs, it also has a 5V/3A BEC inside. Four motors can now be directly connected to the ESC, no more complicated wiring stuff or set up procedures.

The SkyWalker-Quattro-25A ESC combines four high performance 25A ESC and 5V/3A UBEC, wherein the ESC is based on standard PWM control signal. This SQ25A4U has absolutely strong compatibility, which can work with most FC (Flight controllers) and radio set. Each ESC can separately perform throttle trip correction and other work parameter setting.
