Ok I have a GWS receiver that is FM 6ch naro type. I bought a new crystal and its not working. I have a JR TX and it is on PPM, Receiver and TX are on ch 33 on 72 mhz. I have a 72mhz crystal that I bought so did I miss something?? Receiver has a F sticker on it also on the back. Please help thanks.

GWS makes two different versions of this receiver, one for positive shift (JR, Airtronics) and one for negative shift (Futaba, Hitec) for the 72Mhz North Armerican market. Is it possible that you purchased the negative shift version of the receiver and that is why it isn't responding to your JR radio?

I agree with what is said above. You can get some info about instalation, and opperation on [link=http://www.rchotdeals.com/Products/rc/Receivers/gws_r6nii72.html]this site.[/link]

The 'F' sticker means it's for Futaba, or negative shift. You have the wrong type of RX.

This will all be a joke in a few years as people switch to 2.4 GHZ. (But you will still have to buy the correct RX for your radio).
