ESC user manual: high power system for RC model can be very dangerous . manual assumes no responsibility for personal injury, property damage or consequential losses resulting from the product .

Specially designed for multi-rotors, this ESC features several protective functions to ensure safe operation. Firstly, it will automatically shut down the motor if it fails to start normally within two seconds by increasing the throttle value. Secondly, when the throttle signal is lost for more than 0.25 second, the ESC will immediately cut off its output to prevent any potential damage. Additionally, if the motor locks up, the ESC will attempt to restart it three times to resume normal operation.

When using a new Flame ESC or receiver, please calibrate the throttle range accordingly. If the throttle stick is not fully depressed (i.e., pushed all the way down), the motor may produce brief beeping sounds.

The motor beeps when not in the correct position at the bottom of the stick to start rapidly. When in this position, recalibrate the throttle range as it may be too narrow. If the ESC still beeps and there's no output signal, check that the throttle wire is properly plugged into the channel on the receiver.
