CW require more power then CCW ...

Posted by Stefano Santucci on October 4, 2012 at 10:39am

hello all,

I am a newbe who is testing its first hexa, I noticed something that I do not know whether it is normal or an assembly error

I'm doing the first test indor, the hexa suffers a bit of turbulence in the room but I think physiological, however, takes off and is fairly stable without rotation and without too many corrections roll and pitch.

but what I see from the chart gives me some suspicion

    Stefano,

    I am chasing a problem where my hex requires full right-aileron trim to stay in place in the Stabilized mode.  I suspect one of the motors on the left is weak, but short of changing motors at random a graph like the one you generated for your hex may point me to the problem.  How did you generate that graph?

    all the props are in the right way, but  I have upgrade a dji f550 of about 7 cm per arm and i have found 4 engine misaligned of few degrees to right pushing ccw ... this should be the reason .. now I am working to straighten ... will take updated

    I know this might sound dumb but I have done it , are your props all on the right way round, ie writing on the prop facing up?

    Yes, Looks like the Yaw is being compensated with thrust. Please straighten your frame.

    It's very likely some of your motors aren't mounted level, and are producing some yaw thrust, which must be compensated for with yaw differential.  Look at motors 2, 4, and 5.
