Not really sure what else I can tell you. From memory I thin k its an Acoms set. I got it with some stuff I bought on ebay. I use Spektrum now, but used to use 40mhz and have a top of the line Transmitter so its no good to me.

It doesnt have the functions of the Sanwa Gemini mentioned above, or most other top radios, but unless you're planning on racing your car then I doubt you will need them.

So all up, transmitter, receiver, set of crystals (basically all you need to go) and you can have it for £20 plus P&P.

Does the car have a speed controller? This plugs into the receiver, and connects to the motor, in order to make it work. I have a few spares of them, and I have a few rebuildable 19t motors if you're interested.

The 19t motor is way way faster than the kit motor, and the fact its rebuildable is handy too.
