Hi,
I just experienced an interesting behavior of a Lisa/M v2 (Transition
Robotics) with Paparazzi v5.4.0.
I had finished tuning my fixed wing in AUTO1 and switched to AUTO2.
The plane started to intercept altitude and to align himself to the
Standby circle. After a half (more or less) stabilized circle she
terminated the circle and started to roll to the opposite direction. I
switched back to AUTO1 and landed. Post flight analysis of log showed
no anomaly. No warning, no lost RC or GPS, no GPWS warning, no change
in PPRZMode, motor running.
I increased the height of waypoints and started a new flight. The
result was the same. After a half circle in Standby mode, she started
an opposite spiral. I left her to do it and experienced a path similar
to one and a half spiral in strong in wind by constant roll. Post
flight analysis showed a rapid change in Desired.Roll, even the carrot
and the green circle of the Standby mode still behaved as I expected.
The rapid change in Desired.Roll happened more or less in the same
time as Attitude.Psi changed sign. This is only expectation, because
this sign error would ruin all Paparazzi flight in the world. Even my
simulations didn't predict this behavior. Unfortunately the telemetry
messages are not too dense to confirm this expectation. Do you have
any advice what should I do to identify the reasons? (NEO7P works
already fine.)
Regards,
Balazs
