I have a feeling this is a dumb question, but here goes:

I 'm setting up a Wing-wing with an Omnibus F4ProV3, latest AP and MP. I set it up with standard travels in manual mode- about 4mm up and 3mm down, neutral at 1-2mm reflex. When I switch to any controlled mode, the travels are not enough for safe flight. Perhaps 1.5-2mm. If I tried to use a takeoff system (takeoff mode or a takeoff waypoint), I’d need a new wing-wing real soon. If I move the aircraft in all axes, in all controlled modes, the surfaces move correctly, but not enough.
What am I misunderstanding?
If there is any CG imbalance or poor trim, my maiden will not get that happy ending, I fear.

Look on this page and see if it helps you.

The only dumb question is the question that isn’t asked.

Exactly what I needed. Thanks very much. The anti-stall feature was it.
