Almost there but no success yet - Flipping on takeoff. I found setup instructions that say the values for neutral roll and pitch trim in the Advanced Parameters List should match the neutral values that show in the Radio Calibration section of APM Planner. The suggested value is 1500 but the slider is set to 800. My radio PWM values for roll and pitch are 1480. When I try to change the slider to 1480, the tab turns to red. The instructions say to run the radio calibration again if the values don’t match. I tried that and nothing seems to happen to the values in the Advanced Parameters list. Also don’t think I understand how to save the adjusted values for neutral trim. I tried the Write tab in the Full Parameters List but nothing seems to change. Can you point me in the right direction?? Lynn
