Electronics

For the electronics, you will need:

For the ESC, be very careful not to buy the long red/blue ones ! I made the mistake of buying one, and while they claim to work at 2s, they don’t. They do not work above 7.4V, and when they do, they are very noisy.

You will also need servo accessories :

Transmitter - Receiver

If you have a transmitter and receiver, just use them :)

if not, the RadioMaster Pocket Crush is a great complement as it is feature-rich (ELRS + EdgeTX !) and pocket-sized. This is what I use and I love it ! Another solid option is the Tx16s, the bigger brother of the Pocket Crush, which also runs EdgeTX but also features a color touch screen for easy configuration.

Serial or PWM receiver

If you have a PWM receiver, you can use it directly and plug the servo / ESC wires directly to the receiver. If you have a serial receiver, you will need to use a demultiplxer to connect the receiver to the ESC / servo wires. I am using a custom-built demux based on ESP32 and plan to add flight stabilization features to it. I will share the details of the project on this blog when it’s ready.
