Re: Control electronics
Good point about antenna pick-up effects of long wires. I agree that sending analog acceleration signals would be lousy at best. But I don’t see why digital signals couldn’t make it; if RF interference is an issue then you can make the ground line for the outboard electronics a brass tube, and run the signal and power wires inside. That would be one serious Faraday cage for almost the entire signal length.
It is probably a good idea to have shielded servo signal lines, while we’re at it. That would really only mean adding one wire to the above shielding tube (the PWM position signal). Install a wired female plug (GND/PWR/PWM) in the servo bay to make servicing or parts replacement easy.
