But that is just my personal guess.

Whomever you spoke with is crazy. Here is a link to the motors used on the Zenmuse, they are about $100.

No offense but that is not good. Many normal servo driven gimbals do much better. Keep working on the tuning.

Please tell me that horrible noise is not from the gimbal.

Please shoot us a link of an economical servo driven gimbal that will produce the same results for under a couple hundred bucks....didn't think so!

Who said this DD gimbal would be a couple hundred bucks? That may only get you a controller. The full gimbal setup will be more.

Regardless here is better video from a $20 gimbal. I recommend you do some research. http://www.youtube.com/watch?feature...=LCBt_8J0y0c#!

The $1000 seems about right for those advanced products; the cheap/time-intensive DIY work being done here and elsewhere looks very promising for the RC world.

Thanks guys!

Well, maybe he was referring to big motors for heavy cameras?
The motor brand he mentioned was correct, Maxon. But I also considered $1000 far too much. Otherwise Zenmuse woudn't cost "only" $3500! LOL

Why do I have the feeling zenmuse will suffer a huge price drop soon?

Great video but the gimbal ain't better. Watched so many videos my eyes are red To each their own but i"m putting my money on a brushless gimbal and I'm sure it will be under $200 as a DIY. This is the footage that seals the deal:

They intentionally rock the cr*p out of the copter and it's still locked.

Totally agree.

I've been testing with gimbals using servos, but was never happy with the result.

I've been following the SimpleBGC project for 2 months now and this is definitely the way to go.
I've ordered 2 motors, copper wire and a syringe.
And i'm on the preorder list for the controller at the French shop mentioned on the SimpleBGC site.
The gimbal (for GoPro) I'm gonna make out of 20mm aluminium profiles. The most inportant thing is to make it adjustable so you can get the COG exactly on the axes.

Can't wait to get started!

Nice vid indeed. But if you think this vid is better, then you do not need a DDBL gimbal.
Also some post stab done at this video.

Not exactly a great advertizement for a gimbal IMO. And people really need to stop using fisheyes for video.

It makes it hard to compare as well when post stabilization has been done. Need raw video in order to really see the differences.

That is FAR from perfect, and not even close to the brushless gimbal video in this thread.

Best results I have ever achieved with servo gimbal. But maximum 3Bft wind, and do not add the costs, it is not cheap.
Stabilisatietestje (3 min 48 sec)

I'm also looking forward to use this BLDD controller! Almost everything ready now, only the controller is missing.

I'm not really convinced that some of the outdoor vids using Alex's gimbal weren't stabilized in post either. If they want to advertize this thing then we need 100% unaltered footage.
