Hobbywing 20A Skywalker Quattro 20Ax4-UBEC (SQ20A4U)

Hobbywing 20A Skywalker Quattro 20Ax4-UBEC (SQ20A4U)

Hobbywing 20A Skywalker Quattro 20Ax4-UBEC (SQ20A4U)

famous brushless ESC manufacturer Hobbywing released the world`s first 4in1 20A high performance brushless ESC--Skywalker Quattro 20Ax4-UBEC (abbr:SQ20A4U), this ESC is suitable for 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 Flyer has been very popular as a new generation of RC model aircraft, which is 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 assembly and set up. Since HobbyWing has developed the SkyWalker-Quattro-20A ESC, problems will be solved.

The SkyWalker-Quattro-20A ESC combines four 20A ESCs together, useable with 2~4 LiPo cell packs, it also has a 5V/3A BEC inside. Four motors now can directly connected to the ESC, no more complicated wiring stuff or set up procedures.

The SkyWalker-Quattro-20A ESC combines four high performance 20A ESC and 5V/3A UBEC, wherein the ESC is based on standard PWM control signal. This SQ20A4U has absolutely strong compatibility, which can work with most FC and radio set. Each ESC can separately perform throttle trip correction and other work parameter setting. The default parameter could satisfy most application requirements.

Main feature of Hobbywing SQ20A4U:
- 4 speed controllers in 1 board, only 1 pair of battery wire is required.
- Powerful switch model built-in BEC (the BEC voltage outputs from the S3 connector)
- Multiple protection features: Low voltage cut-off protection/ over-head protection/ throttle signal loss protection.
- The throttle range of each ESC can be calibrated to be suitable for different multi-rotor flying control systems/transmitters.
- Maximum speed: 210000 RPM (2 poles motor), 70000 RPM (6 poles motor),35000 RPM (12 poles motor).

Specification of Hobbywing SQ20A4U: 
- Cont. current: 20A x 4
- Burst current: 25A x 4 (>10s) 
- BEC mode: Switch mode
- BEC output: 5V/3A
- Battery cell: 2S-4S (7.4V-14.8V)
