I played with APM way back when, but none of that experience seems relevant now. I'm a first time builder for practical purposes.
My setup should be pretty straightforward:
- Bixler 2
- Holybro Pix Hawk Mini
- Mission Planner
- FrSky Taranis / XM+
The plane flies fine in manual mode. But as soon as I switch to FBWA, the plane either dives vertically, or attempts to climb vertically. It actually does a surprisingly good job trying to hang on the prop, but I'm just looking for straight-and-level flight.
I have not tuned any of the PID parameters. I assumed that default values would be close enough for a platform like Bixler. Do I need to tune PIDs, or am I missing something simpler?
