I also read that with FW and FMS ESCs the throttle trim should be fully down and not neutral. Is that correct? I didn't do it. It's always in neutral.

1. Unplug one of the throttle leads, calibrate. Depower the plane. Then plug it back in and unplug the other one, calibrate. Now both should be the same.
2. Plug in the battery on the side that does NOT have the BEC on it, then plug in the battery on the side with the BEC on it. Now you should get the beeps at the same time. Calibrate both at the same time.
PS. How did you do it with that P-38 in your avatar?

PS, this A-10 is heavy enough and big enough that it won't benefit tremendously from a gyro anyway.

Another similar device that uses something like the bank/pitch limiters are some of the devices that use GPS to do "geofencing", autolanding (Spektrum) and to bring the plane home (eg. the now discontinued Turnigy T1000FC or Bigaole or mini Arkbird). In those cases, the sticks don't work at all when you initiate return home or autoland. Along these lines are the devices with "recovery mode" (eg. Admiral RXs and Lemon gyro RXs). Again, when you activate "recovery", the sticks don't work. Then there was (and may still be) the HobbyEagle gyros where you could train the device to think that "vertical" is at whatever angle you want it to be. I've used that mode in the past, but it was so unreliable that I stopped. Sometimes using the sticks on the other axis gave it a brain fart and the plane went nuts. There are more expensive units like Eagletree (that I've never tried) that may do what you want, but the cost of those may equal more than a 1/3 of what the plane costs.
With the exception of the Spektrum "auto-land" (which may not be available in a stand alone, programmable unit), landing is a learned skill and with this plane, trying different main gear struts may help. Learning the technique on a smaller, cheaper jet might also be a better way to go.
