    Hi all,

    I've got a problem,
    When I switch to atl hold and/or loiter, the bird starts to climb slowly.
    I think I've tried everything without any sollution.
    This is what I tried to tune so far with ch6 on my Taranis TX, during flight:
    "P" Altitude hold (CH6)
    "P" Throttle Rate (CH6)
    "P" Throttle Accel (CH6)
    "I" Throttle Accel (CH6)
    "D" Throttle Accel (CH6)
    "IMAX" Throttle Accel (CH6)
    Throttle hover (in the Basic tuning Tab from Missionplanner 1.3.30)

    all without result.
    Please can somebody help me?

    Paul

    How much throttle do you give it and have you used the trim of the throttle stick?

    @ nVector: Sorry, I'm talking about a Walkera QR-X350 PRO with a FrSky RX, D8R-XP.
    @ Corvette: No, I didn't. Gonna try that today.
    Thank you both so far :)

    OKE thanks. I was a bit surprized with that also, because I use Throttle trim in MissionPlanner.
    That value is at 330 at the moment and the quad is still climbing (slowly).
    When it's at 370 my throttle is under midpoint and when it's on 330 my throttle stick is above midpoint.
    Also tried 20% expo on the throttle.
    Battery is at 50%, so i think that's good also.

    I know, I think it will affect the "RTL" or RX fail save?
    I don't want to trim anything on my TX (not on quads that is)

    Edit:
    After a lot of tuning in totaly windless weather (finaly) I managed to get some good result.
    Now the quad is holding altitude, but first it climbes about 3-4 meters before stopping.
    This is also loiter of course because loiter depends on alt hold.
    Is it normal that the quad climbes some meters or can i tune that to say about 1 meter or preferably 0 meter?

    Finally found the solution. :D
    Built my old CRIUS AIOP V1.1 in QR and guess what?
    As stable as a rock in the sky.
    So happy that there is a cheap solution.
    $ 35 for a CRIUS :) instead of $ 135 for a Devo - M o_O
     
    CopterGirlie und Flusskondensator gefällt das.

    So the fc was the cause after all.
    I'll mark this thread as solved. :)
    Yeah, the prices for Devo fcs are a rip-off. I would never recommend buying one as a spare part.
