    quad pitching back on descent, need help

    I have a qav500, using naza controller and am having problems while descending. It keeps pitching back as I descend in forward flight. I have moved the gains all stout.d and rift now they are at about 110 in normal and 100 in atti. Everything else responds great it flies good just have the problems defending. An suggestions?

    That's really common if you fly in Atti mode. I only fly FPV in Manual Mode
    How many engineers does it take to change a light bulb?
    3. One to hold the light bulb and two to turn the ladder.

    It's happening in manual mode is what is wired. Everything has been moved from my f450 so I'm not sure what the problem could be.

    Can you post a video of the behavior, that would be really helpful.

    thanks for the reply's, I have some video of this but i think its chalked up to inexperience. This quad is bigger than the last one i had and it seems its just being caught by the breeze on descent making the front go up. I am more comfortable flying right to left los especially with quads because they are had to see, so i have been descending into the wind every time. I went with the wind and it does not do it at all, and it flies really good in atti and gps mode, so i have to think its just the bigger profile and props catching more wind than i was used to with the dji 450.

    Ok i got a flight in this morning with no wind and it is still pitching back. Here is some on board video of what it is doing. Sometimes it is more violent than others, when it does it soft it acts like its in atti mode trying to level itself out, when its more violent i correct for it so i dont crash! I am using FM4008 motors from fpvmanuals, the 30 amp DJI esc with naza controller, its on futaba foam tape not the supplied naza tape (took it off my last quad).

    should work now.
