Dear Uttam,

That is possible. There are 3 signs to have correct: 

1) IMU (pfd) correct Body2Imu
2) Control Laws -> correct servo-laws or servo directions
3) RC -> correct your radio file

If all or several are reversed, then the control and RC might be good but the PFD wrong. In the most recent paparazzi, right and up are positive.

Hi guys,

I'm still running V3.9 on my system. Manual control directions are correct, AUTO1 controls and correction directions are correct, but the PFD indicates pitch up for pitch down and vice versa! Roll indications on the PFD are correct. Plane is equipped with an Aspirin 1.5 IMU and a TWOG. Any suggestions?
