Hi i have been using this radio for many years and i love it. I will never own another type.... I recently put in a spektrum system with the micor reciever,, i love it even more..

I have two questions.. Is it possible to send the radio in to have it cleaned and re tuned if i ever need to..

also i have been trying to find an aftermarket wheel for it.. I mainley want to find one that is a little bigger, and looks cool.. I tried one off of the CRX, but it doesnt fit right.. is there another brand that is like hits that i can use.. thaks

The radio can be checked and calibrated if need be and the original frequency module can be tuned if it is out if spec. Just use one of out service request forms if you have to send it in.
As for a wheel.....I am not aware of a aftermarket one that fits the radio.
