MM would cog, now it won't sync with Tx

[supralover72]

I have an airtronics MX-3 transmitter and FM micro reciever, 75mhz. I never could get it to run without cogging, but today, it was the worst ever, and all of a sudden I just lost all control. Nothing moved, nothing worked, and my Tx won't resync. Is it the radio equipment? Is there anything I can do? I've read airtronics doesn't work that well with cc.

Thanks.
