Hobbywing SkyWalker Quattro-25A*4 ESC
The ESC is without program card. You need to buy a program card to change the default functions.
The SkyWalker-Quattro-25A ESC combines four 25A ESCs together, usable 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 or set up procedures.
This unit combines four high performance 25A ESC and 5V/3A UBEC, wherein the ESC is based on
standard PWM control signal. It has been tested and performed absolutely strong compatibility,
which works 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.
