Sounds a bit confusing, Mario, especially if the channels aren't labeled as numbers. Not really knowing what mode the radio was set in for running the excavator at the beginning makes it tough too. Airplane, helicopter, or glider? Is there a manual for your radio available online? I'd like to take a look at it. Maybe I could help you out a little better.

The channel monitor screen you mentioned looking at will be helpful. Try flipping some of the toggle switches and see if they enable the track drive channels (as well as any others). Here again, you might want to try this in glider, helicopter, and airplane model mode. If you didn't change any radio settings for the channels, then I'm going to guess and say it's just a matter of setting the radio into the right model mode to unlock those other channels.
