Flying Whoops with a Hotas System

I briefly explain how I setup a Hotas system to fly whoops. As I point out in the video, I programmed an Arduino board to translate PWM signals from potentiometers in the Hotas to a single PPM signal that can be read by an RC transmitter, such as a Radiomaster Boxer. With the Boxer set to Training mode, I can plug the Hotas into the Boxer's training jack, flick a switch, and start flying. I set up each quad in Betaflight, so the Boxer's settings are irrelevant. Moving forward, I may try using the Boxer to experiment with different throttle curves. Currently, I use the Boxer to fly ExpressLRS quads, and I use a TBS JR Module in the Boxer to fly Crossfire quads.

I didn't start this project with any Arduino programming experience at all -- basically, I started with zero experience and studied tutorials posted by Paul McWhorter (https://www.youtube.com/@paulmcwhorter). Paul is an excellent teacher, and there's no way I could have completed this without his videos!
