Thanks Andrew for the offer on a new one. I will hold off for now. Too painful..hehehe..after extensive research, and tests, the issue was with the receiver. It, for some reason was not receiving inputs on channel 1 nor 4. It was sent in for testing and yup there it was. Coupled with the fact that I was way over powered. At 75 yards, the receiver failed. Up close it worked fine. Bummer. AR7000 fyi guys. I am using these on 4 other models and none have given me any issues. Bad apple in every batch im sure 1 in a million and I was it.
