Hmmm, then it could only mean two things - a wiring connection problem or an incompatibility issue with 7c. To eliminate the wiring issue, you could try to borrow a different type of Futaba radio from a friend e.g. 9c and see if that works.
I'll work on the borrowing a radio idea. Thanks for all the help so far. As far as wiring goes, what is the connection points we are looking for in the radio thru the trainer port?
