The pitch is the only one that works works fine but the Roll and Yaw twitch uncontrollably. The ROLL just goes to one extreme immediately after being powered. I am not too worried about the YAW but without proper roll, the setup is useless.
Accelerator and gyro calibrated several times. I tuned the PID's with several values but the result is always the same.
Thanks for the feedback. I tried the camera IMU on top of the camera and at the bottom. I used the auto IMU orientation every time. I understand the axis and the auto matches what I would manually do. No matter what I do, the PITCH works fine but the camera makes a hard anti-clockwise roll when powered. I can't get the ROLL to work.
I would to following: - 6 point calibration of camera and frame IMU - Very precise mounting of IMUs (IMUs must be parallel to motor axes and fixed firmly, don't use thick piece of duble sided tape) - Defining motors direction - Entering correct number of poles (AUTO function doesn't always give exact values, check specifications of motor) - Auto tuning - Enabling frame IMU - Make sure that all RC inputs are disabled
Something is obviously defective. I tried calibration a million times, secure IMU's, etc. Pitch works perfectly. Roll is always a disaster and YAW works sporadically.
