No deshaker used in post it was shot with the GH2 and 14mm prime lens.
This mount does not work well for me with the 14-42 with the IS on have to turn it off. The V1 mount it worked real well with the IS on but not the G.O. mount. I think the mount relies on proper belt tenison to work well and in that case a little wider belt would have been a better choice for the roll and pitch axis. You may consider changing to a wider belt and I think we all will have better results

Hey Michael,
great deshaker usage.I want to play some with this deshaker.I hope I can use as good as you..[/QUOTE]

It is a Mikrokopter on your first NEX3/5 mount.

Hi Ozan,

I am using an OpenPilot CC board, probably not the best for gimbal control but I know there are others who have used it as both a FC and gimbal control successfully. If we can't get it working well in the next few days I'm going to try putting my Quadrino board on the copter as a gimbal only board. I ordered some more plates for my frame so I think I can make room for it...

Good news, I think I've found / solved the problem! After trying a few different things that didn't work I tried putting the roll servo on a different channel on my FC and the twitching appears to be gone. I got home late tonight so was only able to test it inside just now with a mostly dead battery, but during about a 20 second flight it didn't twitch at all, before it was twitching every 2 - 3 seconds. Hopefully I will get home early enough tomorrow to take it outside for a real flight.

Yay.

Here is a before and after video.

I meant to ask: Did you ever come up with a bracket to hold a servo to trigger the camera shutter on the NEX3?

Ozan,

Could you explain the difference between the TwoDee v2 and G.O Gimbal. If I only plan on using GoPro Hero2 and Sony Nex-5N, which gimbal is best?

hi eagle,
TwoDee is a circular design gimbal,roll turns on center of the lens.G.O. is a classic gimbal,it is working like a pendulum.
My personal choice is G.O. I think that,it has smoother movements than others cause of bearings and 2:1 belt reduction.G.O. tuning is simpler than Twodee for me.
If I must choose one of them for gopro or nex5,I would choose G.O. I like it

you find that 2:1 reduction gets rid of all the stepping on a servo and is smooth enough?

Depending to the servo, yes.I m using hs645mg in my setup and I m happy with it. Of course you can use faster servos but I dont need.
