Hi,
I had two stalls on two different planes (big A tail and Skywalker X5) while they were running Auto missions. They both stalled on a sharp turn, last-but-one waypoint on different days and in different wind conditions.
I increased the ARSP_FBW_MIN and TRIM_ARSP_CM by 3m/s and ran the same mission to test. All went fine with take-off, mission and landing perfect.
Unfortunately, now when I land the A tail using FBWA, the airspeed drops below the 12m/s and the stall prevention kicks in dropping the nose - into the ground!
I know FBWA has enhanced stall prevention so my questions are:
Should FBWA be avoided for landing?
Are there other settings that would allow low risk landing on FBWA?
Other than Manual and Auto, what modes are recommend for landing?
Can I go back to -3m/s but increase the turn speed so it does not stall?ArduPlane 3.8.2 on Pixhawk 2.1 with Here+. I'll dig out the logs if helpful.
Thanks, Tim
