The Sky 3 Quattro 12Ax4 provides the perfect power solution for your quadcopter by incorporating 4 x 12A ESCs with BLHeli software and a BEC into one single unit.

This keeps the wiring to a minimum and allows you to mount this unit in the middle of the frame instead of having to mount an ESC on each arm, allowing for a neat installation needing only 1 set of battery leads.

The Sky 3 Quattro 12Ax4 is loaded with the latest BLHeli software and is packed with user-defined features. The optional USB tool allows you to connect your ESC to the favorite BLHeli GUI software for critical parameter adjustment such as timing and de-magnetization compensation for those high-KV motors.

Coupled with its ability to operate on 2~4S LiPoly or 5~12 cells Ni-XX, the Sky 3 Quattro 12Ax4 is a very versatile ESC for your multirotor or even a multi-engined aircraft!

The Sky 3 Quattro 12Ax4 keeps things simple by having all of the motor leads pre-installed and terminated with 2mm bullet connectors.
4 signal leads (one with power) plug directly into your flight controller's ESC output ports to keep things neater still.
