I'm looking for assistance in connecting three ZTW Beatles G2 20A 2-4S EDF controllers to two Arduino Uno R3 boards. This setup is for speed control of six JFtech 4s version 30 EDFs using a 6200mAh 120C 14.8v 4s1p battery for my scale model. need both wiring diagram and sketch file to upload.

Requirements:
- Manual potentiometer for speed control
- No feedback mechanisms needed

Ideal Skills:

- Electronics wiring skills

Looking for a detailed, functional setup ready for integration.
