Hiya,
Sounds to me like the Ansmann Racing W3 2.4GHZ 3-Channel Combo is the best one to go for.
This state of the art technoloy is designed for the enthusiast.
These radio systems operate on a very high frequency so the signal travels at the speed of light for a lightning fast responce. These radios are on a no fixed frequency, so when they are turned on they will automatically scan across 40 channels to find the strongest available to lock onto. The receiver and transmitter have a unique ID so that they recognise each other and a built in fail safe.
