Frequently asked questions / failure evaluation

Possible failures



The ESC shows no reaction

Check if battery is connected correctly

The LED(8) lights up after connecting the power plug but then stays off

Check Signal connection. When using PWM re-calibrate the ESC

The engine trundles only and does not rotate properly

Check the 3 motor connections (1) on contact (some motor cables are painted and must be stripped)

The Copter looses power after some time.

The ESC goes into its temperature protection. Reduce the load or give it more cooling.

The Copter jerks at full speed

1. the ESC might go to its over-current protection. In this case it reduces its max current to 40A. This reduction can confuse the FC. Please lower the load in this case.

Beep/Blinking Codes

1 beep/blink /second = too many DShot errors 2 beep/blink /second = disarmed because of ESC signal failsave (a too long period without a valid signal) 3 beep/blink /second = disarmed because of a blocked motor or it was not able to get the motor running


How can i change motor spin direction?

How to change motor spin direction is described for each ESC in the ESC wiring and connection section. If you use a full KISS Setup with KISS FC the easiest way is to change the motor spin direction via the ESC flasher tab in the KISS FC GUI.

Do i need to calibrate the ESC?

ESC calibration is only needed if you use a PWM/oneshot/multishot signal. ESC calibration is described in KISS ESC - calibration & 3D mode.

Can i use KISS ESC in 3D mode?

Yes! Please refer to KISS ESC - calibration & 3D mode. If you use the ESC together with a KISS FC the 3D mode can be set via the ESC flasher tab in the KISS FC GUI.
