    DJI F450 tilts backwards on takeoff

    I'll try that. When its on the ground it seems to react the correct way but I can't tell since i can't seem get it to get off of the ground. So when I try to lift off I'll give it some of the right stick forward and that helps. But I'll give it more throttle and then it'll still flip. Even with...

    DJI F450 tilts backwards on takeoff

    If I get a chance later I'll try to post a video of the copter in my hand.

    DJI F450 tilts backwards on takeoff

    @chris. Everything looks good and moves correctly in the software. And they all looked like they were centered after I calibrated it.

    DJI F450 tilts backwards on takeoff

    I tried atti mode too. If give it lots of throttle and it flips quickly. If I hold it in my hand while its level I feel it pull backwards.

    DJI F450 tilts backwards on takeoff

    "Please provide more pictures and another movie." -- of what? I tried it in each mode again. I held it in my hand with manual mode on and it just feels like it wants to pull in my hand. It doesn't feel like it'll fly level. I just re calibrated the GPS and made sure the naza was blinking...

    DJI F450 tilts backwards on takeoff

    IMM/ Intel didn't make a difference. Still tips backwards and flips over. Do the legs change the measurement of the Z axis? I don't think it does but I just want to make sure. It's strange because I took the motors off completely and remounted them and it still tips backwards. So it gotta be...

    DJI F450 tilts backwards on takeoff

    The manual said the bullet connection postions do not matter with these motors. They have markings on the side of which way they should spin. Each one is spinning correctly. The red arms are the front of the copter. So I have the GPS unit on top facing that way, and the naza under it is also...

    DJI F450 tilts backwards on takeoff

    The motors are correct and the props are on the right way. With these props/motors its impossible to them on the wrong motor. Also the diagram from the first post is wrong anyway. Motors 1 and 2 should be at the front and 3 and 4 at the back. The solder is fine and ill secure the cables when...

    DJI F450 tilts backwards on takeoff

    Just built my F450 and I can't get it to lift off. Notes: It always tips backwards, if I give it more thrust it will flip backwards I've calibrated the GPS a few times and no change in behavior. IMU has been calibrated. Motors are confirmed to be in the correct position and the props...
