MECH_ENG:
My previous post was confusing, sorry about that.
The tether will consist of 3 parts: Cat 5 cable, 12 gauge power line, and a video line
The Cat 5 line will only be used as a connection between the analog joystick and Arduino. Will noise on ethernet line from the current in the power line be a significant concern? Also the pots in the joystick are 5kohm.
P.S.
You have been extremely helpful and have helped me prepare for questions during the final presentation of the desgin, thank you

Whether induced noise from the motor cables will be a problem or not is hard to guess, as it depends on several factors (the main issue being how the motor controller handles things). Terminating the cable impedance correctly and making use of the twisted pairs as intended will help, but, to repeat myself, go digital and save yourself a lot of worries.
It's no skin off my back, if you want to connect the pots via a 50' cable and tinker with that for som time, but you're gonna end up with digital transmission in the end (or a complete control Chaos), so why not save yourself some time? :)

Thank you for your help!
