I evaluated the signal of the ESC via the Arduino to make the backfire look realistic. The Backfire is triggered when you go fast from full throttle.

What you will need:

Arduino Nano

piece of pipe

cable ties

wire

Step 1: Schematic Composition

Step 2: Arduino Code

Attach the servo to the burner. In my case, I did it with superglue. Works perfect.

Be creative. :-)

Currently my project is in the development phase. The next step will be to build an exhaust that looks realistic.
