I recently updated the runcam2 gimbal for my quadcopter design.
To see the previous design, check here http://diydrones.com/profiles/blogs/mantis280-3d-printed-folding-drone-with-gimbal-in-test
Gimbal mount is compatible with GoPro's slide in and click mount.
Total weight including runcam2 cam is about 150g without battery.

I will continue upload some aerial video footage next time.
Loading DIY drones page is getting slower in my country. I am planning to open my project through kickstarter campaign and once evrything done, those pldegers will have files to print with minimum price.
Thanks Chris, I see you're referring to gimbal lock with that configuration. Maybe I'll have to test it on my own. I would bet it works fine, however the benefits will only support specific cameras.
I was wondering the same, will you share .stl files ? :)
Hi Daniel: Assuming that I have not misunderstood you... If a the roll axis was directly connected to the camera & the pitch axis connected between the roll axis & the aircraft frame... The pitch axis would not function as a pitch-only control (with respect to the horizon), unless aircraft was completely level.
As the aircraft roll increases, the effect the of the pitch axis of the gimbal would change to a mixture of pitch & pan.
At 90 degrees roll ,for example, the gimbal pitch would act like a pan-only axis. ( with respect to the horizon).
A standard gimbal controller would not work properly with that arrangement.
If servos were used & controlled with the r/c radio (no gimbal controller) it could work, but the apparent pitch would still change with the bank angle of the aircraft.
Kyu, no your design is prefect the way it is. I'm referring to using flat cameras or board-like cameras. But I've never seen roll first brushless gimbals. So I was wondering if anyone tried it or if there are reasons to avoid it.
Thanks for the comment. Is "roll first" means roll control is attached first to the camera? If my understanding is right, there are less gimbals have roll first and pitch next. Because my gimbal has pitch first to the camera then roll control. Runcam is specially designed as flat and long, putting rolling motor first to the camera makes even longer design and pitch motor has to control more larger volume. So I decided not to make rolling first to the camera.
Is my description answer to you?
Will you post stl files to print the parts?
Nice and clean 3D print. Love it. The motor mounts are nice and clean as well. Going to post specs?
So question since you build gimbals, has anyone ever built a roll first gimbal? Every gimbal is tilt, roll, then pan. The only exception are servo gimbals.
For flat cameras like a GoPro it would sense to place the roll motor directly behind. Or is there a reason?
