I have my PV2+ back from service center after 3 weeks sitting there. I did all firmwares update, calibrated all RC sticks and PV2+, calibrated the compass on location. However, when I flew it in Course Lock under Naza mode, it went well in up/down, turning but not right under right side control. Pushed up didn't go forward, pushed left didn't go left. From the RC system (see attachment), I selected Mode 2. Should I select Mode 1 to make the CL work ? What's the difference betweeen Mode 1 & 2 ? Thanks.
