What is the smallest Rc receiver  ?

something smaller then the zip zap car's at radio shack.

If you're talking about the same mini RC racing cars that I'm thinking of, you're getting REALLY small. Though I'm not familiar with the zip zap cars so a link to a picture of them would be helpful. At least here in Canada they're like $25 each, and that's partly due to the fact that the components need to be so tiny. The one I used in a recent robot is a GWS Pico receiver:

But there looks to be even tinier ones that they sell, so you could check them out. I'd shop around.
