Wecome back !
I just got back into RC myself.

Now that your back and ready to stay, kick in the bucks and purchase a synthesized transmitter and receiver. Then you can fly on any channel you want anytime you want.

Hitec makes a moderate cost transmitter but not the receiver.
Polk Hobbies makes the receiver.

Futaba will be coming out with a module for their 9C transmitter but no receiver ( unless you buy their top of the line at $300 ... ug ... too much).

Multiplex will be coming out shortly with their synthesized system ( I've been holding my breath ... but turned blue ... so I quit).

The remaing systems are out of my price range.

Again ... welcome back ... and good hunting .... I fly channel 50 and wait my turn .... but it's never very long.
