APM 2.5 Quad refusing to stabilize. Patience wearing thin. lol

Posted by CFC on October 22, 2013 at 9:56am

When held in hand it violently makes adjustments that over correct and continues to accelerate making it worse. Also despite the radio calibration working fine and the radio inputs corresponding correctly with where they should on the radio calibration, it seems to pitch when I roll and pull at an angle when I pitch. Yaw seems to do ??????? I cant explain that LOL.

Okay so so far I have:

-Done live calibration

-Calibrated Accelerometer

-Calibrated ESC's

-Done motor test in terminal and was correct order and prop rotation

-Ardu is facing front of quad

-Started to play with PID settings but I'm really inexperienced

-In dire need of help

What do I try next?

    Also based on your comments I would check some high-level airframe parameters:

    -make sure simple mode is off (unchecked) for the flight mode you are using
    -make sure configuration is set to X and not + (assuming you have an X config)
    -make sure you loaded the quad firmware, not hex or another version.

    Compassmot is basically manditory to perform as many problems can stem frm this. A compassmot of anything over 30% is said to be problematic. You may need to increase the distance from your GPS to your wiring.

    Did campassmot test and had 150% interference at full throttle. How likely is this related?
