When using StableApproach with the Zibo 737 there seems to be a bug causing the stab trim switches to get stuck in some cases,
which causes a stab trim runaway.
This only happens when using the dual trim switch commands, not the normal (single) trim command.
If you have those commands assigned, the problem might occur:
Pitch trim A upPitch trim B upPitch trim A downPitch trim A down
As a workaround for now, you need to use the single trim commands:
Pitch trim upPitch trim down
To be honest, I have no idea what causes this strange behavior. So it might take some time to get it fixed.
