I'm trying to build a short-range (for now) first person view rc car. I like the Mega board because of its expandability, so i'll probably go with that. there are plenty of cheap FPV setups out there for rc cars and planes so I can take care of that. I don't think i'll need an h-bridge because i'll probably just use an rc speed controller and I'm pretty sure I can just use a servo output on the mega for that. I want to be able to run it outside with a line of sight range of 100 yards or so (or more depending on $$). I've seen the Xbee and the WiFly but i havent looked at the capabilities because i dont really know what is required to run servos.
I guess my first question is what type of wireless setup should I use for this? Or, what are the options out there that are somewhat affordable? I'm looking for something with decent range and the ability to control a bunch of servos.
How difficult is it to write the code for the steering wheel? I would like to have pretty high resolution, not just full left or full right. Same thing with the pedals.

A byte sized value - where to position the servo.

You want easy-to-use and reliable, or cheap?

If you are talking about cell phones, "decent" range is one thing. Satellite phones have a different "decent" range. Define what you mean by "decent" range, then we can discuss options that have that range.
Is a "bunch of servos" like a bunch of bananas. Specific values, like 8 servos that get new values every 10 ms, are much more useful than "I need to control a bunch of servos once in a while".
