What I really have highest respect for is the fact that all the "Big Players" with pockets full of money put rumours on the net, drop pictures of their next killer hardware here and there, month before they are ready to sell the Gizmo.....the usual marketing crap.....and then comes this guy (or should I say gentleman) who got a problem to buy a new camera because of a thight wallet and shows us how it should look like !!!
...no big R+D department (yeah...we know our stuff is really bloody expensive, but there is a lot of research behind...and the marketing cost....and the cleaning lady....and all the dope we have to smoke to get our visions....) Just be talented, get the stuff rolling and come up with something jaw dropping....that's what GotHeliRC did.

Now guess whom I would support with my hard earned cash......???

The dope dealer? Serious game changer and I have no doubt dji will pull a page out of the Red playbook and half their prices before summer. Whatever happens it sure is an exciting time in gimbal development, the first casualty being the good old pendulum style gimbal.

I know... but then it said to use H264 for output... then I check my editing software (Edius) somehow I can't choose H264 as output. So?

That's just recommended - I upload GoPro footage straight from the camera and it works great.

edit: I rarely put music in my videos anymore but AFAIK Vimeo doesn't hassle you about copyright issues.

Since when was the pendulum style "good"? IMO, it was always just old. ;)

So, where do we line up to buy this thing?

I am not sure yet, since we don't have the money or man power to manufacture the board... we have to wait and partnering up with others. At first I thought FPVmodel agree to share the production with us on the board, but they then decided not to sell the board alone. So right now I don't really know for sure. But if everything go well, we should have like 10-20 boards in two weeks.

As for the GImbal, I can make. But I am not sure if anyone interested in my pendulum gimbal? it's heavy and ugly? :) The only pros is that it's super stiff, no flexing.

Hummm...

2-3 weeks... maybe a total of 30 hours.... Wounding the motor was a b$4$4... figured out the vibration is another pain.

When I first tunned the system, it was hard, because I couldn't tell how good the stabilizing was, remove the memory card and watch the video... did that like 30 times. But then Alex update the software now for easily tune. It now give you feed back on how much movement the IMU is getting and give two different rate... So you can basicly tune it and watch that instead of your video.

Amazing results!

Do you think that the motors you used have enough torque for larger cameras? have you tested with any ballast weight to see how the gimbal reacts (since i know that you are lacking a camera)?

I have not test it, but I believe the motor have enough to run a dslr. Even Alex himself said it should be able too. The biggest factor here is the balancing of the camera, if it's perfectly balance then the motor is only compensating for the bearing friction. I'm working on a DSLR mount right now, will let everyone know soon. All though I only have a rebel xt, no video, not sure how I am going to test it... haha!

Really awesome DIY brushless stabilization!! How big is the shaft on your roll motor? Can it be made to be like 6-8mm? It seems to me this point is bearing most of the leverage. Or am I missing something?

Yup, that's the issue. Right now the stock shaft is 3.17mm, I don't think the roll can handle the weight. It can be somewhat easy to change the bearing to allow 4mm shaft. But I was thinking to bore out the tower and change it to a 5mm shaft. 5mm shaft will do... no need for 6-8mm.

Goth Heli RC Congrats...! its great...!

Now the best think you can do is to realease a kit motors + controller for the Cinestar Gimbal and i DIY to put the motors..! i think that it is easy..!

Star winding, 130T with .22mm on for Roll, 150T of .17mm wire for tilt. Purposely wounded it different to see what it does.

are you talking about total turns per motor or turns per arm?

do you think that the same motor winded in the right way can manage a bigger camera as the GH3 or bigger?

I am pretty sure it can handle a CX730 or Nex5 ect no problem at all. The gimbal I am working on now the camera plate is 170mm. 5D size. :) Let us pray the motor can handle it.

Can anyone with a Nex5 tell me what lens are normally use for AP? and where about does the camera balance from the mounting screw?
