Thanks for your input guys. I went to the LHS and had him check that out. He had several TXs in the back and we tried them all. None of them worked unless the TX was turned on. My TX was set on PPM (FM). Even tried to see if my TX would work as the slave. Seemed the only way to use the Slave TX was by turning it on. We did all sorts of ground tests, and everything worked. Even did several test flights with no problems. If someone here is a radio expert, please tell me what is wrong or what other options to try.

Thanks
