Impressive work! I don't know how the Futaba RC system works- do you find that moving to a mark is precisely repeatable? I'm not sure if it uses an optical encoder (which should not drift over time) or a simple potentiometer (which probably will).

The futaba radio is just a pot, but so was the Sietz wireless system (it actually had a Futaba airplane radio in it). More important is the reciever. If you get a nice one like a Birg, it won't respond to any radio other than the one it locked with when it turned on, even if you have another radio on the same frequency.

Be cautious of interference since you're yousing a car radio, which are pretty common.

Looks like a fun project.

Cheers,

Nick
