    vortex 150 motor revving up to peak with no throttle inputs !!video!! please help!!

    My vortex 150 is behaving irregularly. I did the initial OSD set up, proceeded to betaflight to make sure everything was set up correctly fail safe, Switches etc.


    Once I proceeded to arm the vortex I noticed when giving a small amount of input a couple of the motors seem to rev up and continue to rev up with no stop until I lower the throttle all the way to zero, but once I bring the throttle back up even a tiny bit I get the same reactions


    I have not even flown it yet these problems happened right out the box


    Fast forward to 1:35 to see betaflight motor screen

    This is pretty normal and should fly fine... as long as props are on correctly and the motors are spinning the right directions for their locations.

    Yea but it didn't feel normal it shot up in the air an starts yawing 360* with little throttle input an no yaw input (maybe about 3 clicks above zero throttle an left it there) an does not stop reeving up until I completely kill the throttle....

    In the video i had to turn the transmitter off for it to even come down...

    Check your motor spinning directions. One motor or 2 motors are spinning the wrong way, that's what's causing this.

    Do you think that would explain the motors revving up continuously until peaking out? That might explain the quad spinning in flight maybe, but I'm not so sure about the continuous revving up of the 2 motor with No type of input from the control, if you refer back to 1:30min of the video an watch as the two motors just start increasing RPM's with just a small amount of throttle. It continues to rise until I kill throttle an raise it back up to any given position then it starts increasing again.

    An because the quad took flight I'm guessing the props an the motors rotation are good but I'm still sort of new to this so I can't be sure I'm correct on that theory, someone correct me if I'm wrong please.

    Perfectly normal with Airmode on, this is not a defect or anything.

    Air mode isn't on an what's with the continuous yawning 360 degrees while shooting in the air without any yaw input from my taranis? That's not normal

    Number of possibilities:

    - Props on the wrong way/motors
    - One or more motors motor direction wrong
    - FC orientation changed in setup
