This is a perfect matched system for you JR Tx and it is Dual conversion. Less money AND in my opinion a superior performer to the Jr 600 and has a proven track record of durability, best of all If you have to send it in with crash damage or whatever you will be dealing with the best customer service bar none and I have had experiance with all four of the majors customer service.

Agine there are many options avalible to you.

This is the crystal that you would use in the above Rx (eight bucks) on the frequency of your Tx, Do not use a JR crystal in this Rx.
