Recommendation on TX system for a crane

[Lord_Fabricator]

Yeah, I'll definitely be using an Arduino of my own. I'm not exactly sure how to do that though. The switching four channels on the fly would be great for flipping the sticks from crane to truck modes. I think, if I can get an Arduino to do most of the work, I can cut the channel count down to 12...

I'll need to make the Arduino read 13 different sensors, and output 21 PWM signals, and 4 toggle relays...
