    It was only at the one spot of the video. Probably just picked up an oscillation at that moment that made it through the dampers to the camera. Rest of the video was good so I wouldn't sweat it.

    Yeah, you're probably right. It is a flying camera after all.

    Thats not the full video, I was talking to the owner of that pv2+ on FB yesterday and he's a bit bummed. The original video is 11 mins long I think and the jello was tru a good bit of it.

    He should check his camera mount as well as motor & prop balance. I've seen a fair number of P2V+ videos and have not noticed jello except in this one.

    Yeah he's going to go tru everything, I'm surprised myself because most videos I've seen have been perfect. Hopefully it's just a once off and we dont start seeing a flood of new jello videos

    I just watched the video. For the most part it looks pretty good. Just a bit of jello creeping in on occasion. I would check the camera mount, make sure all of the motor screws are tight, and check the prop balance.

    When you compare it to some of the other gimballed footage on P2Vs its not bad at all, pretty good I thought. Its only minor at best and may be the footage itself not aircraft induced. Compare it to an ordinary P2V and its light years ahead.

    I just posted a thread about this. It's my video you referenced in the OP, again given below (see 2:17):

    [youtube]http://www.youtube.com/watch?v=RlW5_H-SCig[/youtube]

    ... And here's a flight I did the next day. The wind actually much heavier and more sustained this day, but I was not flying full throttle as often as in the prior videos. It seems jello was reduced, don't see much of it, just a bit:

    I'll update after more flights and fiddling around.

    Prop balance? Maybe.

    More rigid dampeners needed? Maybe.

    fairly acceptable.
    at that altitude there could be wind gusts and might cause shakiness.
    -and the gimbal can only account for so much.

    It's nota case of prop balancing, otherwise you'd see jello thru-out the video.

    Thanks Gizmo, yea the more I fly, the more I am seeing that it's not a big problem, just something that will happen sometimes under the right conditions.

    I'm thinking its just on occasion the combination of prop speeds, balances, and vibrations are throwing just the right forces into the system that the oscillation gets past the dampers.
