Thanks to all for all the work and patience here.
Tx/Rx: Graupner MX-20, GR-24
All was well with my first AP setup of a flying wing Falcon. GPS worked, controls moved in the correct directions, I even had the travels set.
Now, nothing moves. Servos inop. Re-did all configurations including the radio page successfully, except the servo output page, where only random green bars show up.
This happened a couple times, but it went away. I thought I did something wrong, and finally got it right, but--no.
A week of frustration. Help, please.
