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 Favourite BLHeli GUI software for critical parameter adjustment such as timing and De-Mag compensation for those Hi-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.
