ESC Calibration

How to calibrate ESC on my quadcopter or plane?

The calibration of an ESC is actually quite simple. Just make sure to remove your props so that you don’t get any nasty surprises if anything does not go according to plan.

Standard Procedure to Calibrate your ESCs

  1. Turn on your RC transmitter
  2. Put the throttle stick to the maximum (high) position
  3. Connect your ESC directly to the throttle channel of your RC receiver (not your Naza or other flight controller). You can leave all other wires connected as they were.
  4. Connect your battery to your plane/helicopter/quadrotor. The ESC will beep once or several times to confirm that it received a throttle high input.
  5. Lower your throttle stick as quick as possible to the lowest position. The ESC will beep again to confirm a throttle low position.
  6. Unplug your battery and turn everything of. Your ESC is now calibrated. Do the same procedure for the remaining ESC and don’t forget to connect all your wires properly again.
  7. Done.

ESC Calibration Cable

If this procedure is too slow or you have to do this often, you can purchase an ESC calibration cable. It helps you calibrate your ESCs of any quad all at once, without needing to perform any solder work. Plug each ESC into the sockets, plug the servo plug into the throttle channel on the ESC and you are good to calibrate all SimonK ESCs exactly the same, quickly and without hassles. Works best with the ESCs already mounted to the quad. An ESC with BEC is required to power the receiver during the calibration. Most ESC sets come with one ESC that has a BEC.

Calibration of ESCs with a CC3D from OpenPilot

If you have a CC3D from OpenPilot, a good step-by-step guide can be found here on how to calibrate an esc. In short, do as follows:

  1. Remove all the props first and disconnect your battery from the ESCs, then power your board through the USB.
  2. Go to the output config panel in the configuration gadget, check the “test outputs” function, and confirm that you want to continue.
  3. Move the slider on all ESC output channels to the max value you like (for example 1900 microseconds). Link the outputs so you can calibrate all ESCs at once.
  4. Now apply power from your battery without disconnecting the USB. Your ESCs will boot and beep accordingly, indicating that they received a high throttle set point.
  5. Now hit the “home” key on the keyboard to move all sliders back to 1000 microseconds. It is instantaneous and much faster than trying to slide it. The ESCs will beep several times to confirm the low position and all will be calibrated properly.

  1. Wonderful site you have here but I was curious about if
    you knew of any message boards that cover the same topics talked about here?
