This is a manual for our 4in1 Quadcopter ESC, and will talk about some of the functions and how to set them.  These quadcopter ESC combine 4 individual ESC into one package.  Because there are 4 different ESC you will need to calibrate/program each one on its own.

This is the manual for how to program our BLheli ESC.  Most ESC ship with firmware that averages the speed changes to your motors for smooth operation, but for mutlicopter applications its much better to have immediate response for the best performance which is what the BLheli firmware.  The BLheli firmware is designed for use on multicopters and helicopters.
