    SO i just built a new heavy lift for flying m5 but unsure of the gpx file. Due to the new active braking it seems to through the numbers around a little. Odd numbers drawing more current? hmm hard to say. I have triple checked motor alignment and done a good calibration

    Today was super windy 7ms plus so I tried to find a quite area and just hovered at low level.

    If someone could have quick look it would be appreciated.

    running a Double Quadro V3 - Cool with v1.08 software
    fc is 2.5 with 2.06e
    navi 2.0

    Cheers
    Jason

    Can you double check if your motors are perfectly level?
    I don't see anything odd in your logs. Everything looks good.

    Looks more like one or more of the motors is not quite vertical so it's inducing a yaw-moment on the aircraft which the odd numbered motors are having to counteract.

    You might want to consider flying the copter at eye-level about 2 meters away from you so that you can look at the prop "discs" from the side -- it's pretty easy to see if one of them is canted over....

    Andy.

    When measuring current draws in flight on a windy day, be sure to spend an equal amount of time "nose out" and "nose in" (assuming you're able to fly that way). That will even things out. Plus, hovering at 1-2 meters is not ideal, as you will encounter a bit of self-created turbulence when you're that close to the ground. I prefer to be at least 3-4m for such things.

    OK thanks Andy and Steve I will double check motor alignment for the 3rd time for a 1st test flight in such windy conditions (typhoon number 13 for Japan!!:eek: )it was actually really stable. I just wanted to see if the thing flew or not and was not prepared to crash it on the first day out!! lol so I stayed low to the ground checked that flew.
    Now to wait until the storm passes so I can take it for a real spin!!
