Re: [Paparazzi-devel] FW - pitch offset problem

[Loic Drumettaz]

Hi Edouardo,

Another option than tuning the elevator neutral is to switch to "adaptive" control loops.
This allows you to use integrators on the attitude loops, which can cancel the offset between desired and mesured pitch.
About the problem you experienced in survey: were the desired course, roll and pitch expected with that flight plan?
I think that i already noticed in survey mode such problems. So i guess you should check desired variables and waypoints positions in the flight logs, rather than attitudes.

Hello folks,
i have some problem in my last flying wing.
When i start the advanced poly survey the plane go to the start point and never get out from the circle even when reached the correct altitude.

I analyzed the logs and found that the pitch are aways with some offset (8 deg)
See the attachment:

anyone know this problem?
