Mike,

You would probably get away with it...

Let me extend your line of reasoning:

Q: What would happen if I use a 10 ohm pot?
A: I doubt if the 5V internal power supply in the RC can provide 5V/10ohm=0.5A of current.

I would think that 100K is probably a value such that a team could use 100K pots on all analog inputs simultaneously and it would work.

For a definitive answer, I would post on the IFI Technical Forum.

Regards,
