Hi,

These are being built by DIYers around the world. The basic electronics can be purchased, but the gimbal mount fabrication and motor rewinding is being done by these early experimenters.

Yes, you add weight; just small weights in the right places, and adjustable for different cameras.

The CoG of the White, Silver and Black Go Pro Hero 3 are all different so you have to do something anyway.

If not on the gimbal itself, then maybe something like this?

Hi,

you really want to know how we deal with it, do you ?

things are ajustable to match the 3 go pro versions, but without stress

Best regards,

Bo is looking to make a landing gear for the phantom that is tall and wide enough for this is gimbal. Could you give us the height and width please?

Height is 95mm with a set of M3*8 vibration dampening rubber standoffs. (Bottom of camera to top of standoff, you might want to have some clearance underneath)

Width is 110mm

Width - 110mm.

Depth - 115mm.

Height - 87mm. without vibration dampers

We currently use 8mm and 15mm. vibration dampers

Allow for some movement around the gimbal.

EDIT:

Jussi, you beat me to it while I was writing.

What type of dampeners are you guys trying? Will they need to be in compression or tension to properly function? Most dampeners that I know need to be in compression to function properly. Would they gimbal be easy to hard mount to a plate if we already have a vibration damping scheme in place?

HI,

i'll check on the phantom that comes here, and see what we can do

The infos i had about the Phantom mount are:

72mm height for the mount, with a clearance of 90mm to the ground and 100 mm width with original landing gears

Mount is 30mm width and 48mm lenght, 40m between supports which are m3 (data to check)

If the gimbal is fitted on the right spot in lenght, the landing gears should not interfere a they are U shaped .

I'll check this on the frames i'll receive

BEst regards,
Fabien

It will fit nicely, snug but nice. I just measured my Phantom belly to ground 97mm, actual legs is side mounted and 120mm but our of the way. 100mm side to side space.

There is two mounting holes in the front. COG weight should probably be under the rear hole or even a bit further back.

That said, I don't think the particular fit of the Phantom is hugely important to this awesome thread. and I am eagerly waiting to get my hands on a brusless gimbal from Europe.

What is the latest on the motors and gimbal hardware? Are you going to sell it?

Thanks for your hard work!

As the power of the system is rather limited, is there any facility on the brushless controller to correct for the camera being displaced by violent manoever, or turbulence, as there doesn't seem to be any actual position feedback?
