Chief,

I had the same problem with a 4YF, even though it's not a computerized radio. Aircraft radios seem to have different receiver receptacles/channels, as opposed to a dedicated surface radio receiver such as the suggested 4VWD. So, if you hook up the connections the way they describe them in the manual, your functions probably won't be on the sticks that are shown in the diagrams.

Not sure if that radio allows you to switch channels among the stick controls, but the way I finally had to get it all straight was to hook up servos to the receiver and actuate them with each stick and make a diagram showing which receptacle on the receiver was what channel (stick) on the transmitter. Sure, the manual for the 4YF showed this, but the aircraft terminology was confusing me when it was time to hook up each function from the DMD.

For example, on the 4YF the receiver receptacles are numbered top to bottom; channels 1-2-3-4

On the transmitter, the matching stick controls are backwards.
Left stick left-right is channel 4.......Up/Down is channel 3
Right stick Up/Down is channel 2.......left-right is channel 1
Hope this helps some.
