You have to at least start your project yourself, we don't provide whole circuits on demand.

Maybe some details (really hate these secret projects and all the guessing), just spill it!

Are you using an existing R/C transmitter/receiver, or are you hoping to build the whole thing from salvaged parts and Radio Shaft? There are some simple on/off circuits that use the PWM signals from the receiver. Haven't looked in a couple of years, so no quick links today, just remember seeing them for lights, releasing a payload, lighting fireworks... Shouldn't be hard to find.
