Re: LED's on Relay Ports?
Leet,

You'll want to put a current-limiting resistor in series with the LED. There's only a limited total amount of current available at the RC ports, and tying the LED from output to ground will either draw enough current to burn out the LED or may draw enough current to cause a drop on the RC's internal voltage.

If you need more current than the RC can provide to get to your desired brightness, you _could_ use a Spike or another custom relay (or transistor) and a bigger current limiting resistor to run the LED off 12 Volts. Double check section 8 of the rules to see if what you have in mind is legal.

Steve

P.S. Let me guess - these are indicators to let the Robocoach know what command has been sent? Maybe color coded?
