just want to know who uses to chassis on one remote
 

anyone?
i do

i control 13 chassis w/ 1 remote

The 4 band controller can control all your cars. I use it for my cars to save batteries, although the range is a little short.

that four band controller is the one with boost capabilities right? does anyone know if the skyline 3 pack is a booster car?

the skyline 3 pack is not a booster, just a standard 35mhz chassis

i c... well if thats the case im prolly gonna need to find one!

read my sig about boost

And finally to actually answer the kids question without needing to get a 4 band controller (which I still can't find)

Get chassis on the same frequency. You can't race them against each other, but you can just buy speed sets and save money over buying a whole set of controller and car.

try this website:

it's Sheldon's Hobbies website; Sheldon's iis my LHS

TWENTY FIVE BUX for a clone? omg they charge too much.. i get real MS's from my LHS (hobby town) for 24.99 and the imports are 34.99, imean damn i understand they need to make money but GEEZ :) (.02)

yeah, even their regular Bit Char-G kits are expensive. I only go to sheldon's for body sets and booster kits. b/c they are cheaper than some online sites [xcept ebay]
