2.4GHZ Radios

[DaveG28]

Hi,

2 questions, what is the difference between the FUtaba 3GR 2.4ghz, and the 3vc 2.4ghz? I assume the 3vc is better but in what ways?

Also, does anyone know how to set up multiple receivers on a transmitter with 2.4ghz (ie have a receiver in each car I own rather than just one receiver), I am not sure how you link receivers/transmitters when you don't have a fixed frequency!?
