Default Making a GoPro gimbal

Heres some pictures of the first completed part of my GoPro gimbal. So far ive got the tilt servo modeled, as well as the GoPro carriage and the rotation arm.

To complete these parts, the carriage needs the rubber band anchors added to it, I'm also considering adding a piece that wraps around the back of the camera.







To complete the project I need to select and model the rotation servo, and work out how the rotation arm will turn, ive got some ideas, and will keep things updated here, as well as pictures of modelings, and the parts once I have 3D printed them.

iam still new to the gimbel area . but if i may .. i seen a few videos where the lens of cam is off center from the rear servo or bl motor .. i noticed this makes the center point of the video wobble like . there was a video of a guy in a basketball court . and the hoop was center video and it was not good. very noticeable it would go off center lines of video so easy ..

ill have to find the vid and post it..

but your gimbel looks good so far iam still trying to figure out if i want servo or bl motors myself . i flown one with servos seem smooth like butter but not 100% sure yet

That's something I considered when i started the project. Ive got the tilt pivots just about at the lens center, and I am planning on having the roll pivot slightly off to one side so it is also aligned with the gopro lens.

A brushless gimbal looks amazing but its slightly above my price range after this whole build, my new Tx, and a gopro 3 Black.

Incorrect, actually. For some reason many people seem to think that the camera lens positioned in line with roll axis of the gimbal has some benefits - it doesn't. If the gimbal does its job and maintains the camera mount level why would it matter how offset the lens sits? From the standpoint of gimbal performance I can see it beneficial if the roll and pitch axis of the gimbal are centered on the camera's CoG, not on the lens's.

To avoid your camera swinging what matters is the gimbal be positioned as close as possible to pitch and roll axis of your aircraft, but that's much complex challenge and it may or may not be attainable in your particular setup...
