It is still advisable to wire a 100-ohm resistor in-line with the "-" lead of the LED. I use that trick to light-up my RC-Crawlers.

Good idea but wouldn't the voltage to the light be the same as the receiver is putting out? That may be 6 volts?????

Use a resistor?

OK, will I need one on both legs of the LED Tom?

One leg. Mostly the " - " ( the short leg)

If You are unsure, check if You got 5v LED's or 3v LED's.

The RXputs out something like 5.4 v, so, in case of a 3v LED, You could wire two of them in series. With a 100 ohm resistor on each LED, they should last along while.

With a 5v LED (often the super-bright kind) just wire them in parallel with a resistor on each LED. It's the way cheap LED light-sets for cars are wired.
