!UPDATE! - 10 March, 2017
I have changed the pinion gear to fit in a larger base plate mount and changed the base mount as well. this is to align this project with a similar project using store-bought Acetyl gears. For more information please see my Wiki article on this newer project:
Been waiting for someone to come out with a 12-20 gram 360 degree servo to use for a pan and tilt for some time now. The idea was to build a similar Pan & Tilt to my Heavy Duty unit but with hopefully half the weight. Well I didn't find a smaller 360 servo but I have put together a lightweight unit (51g) that is more robust than any of the small units I have purchased and tried.

This project started with store bought gears which are very well made and smooth. The issue is getting them attached perfectly to the servo spline and camera mount so there is no wobble or gear-train binding. To solve this I found a gear generator that works in my CAD program which gives me the ability to create printable high quality gears with the features needed to make the attachments. Of course it requires a fairly high resolution printer, 0.1mm or finer, to print these pieces succesfully.
So, with a gear train I can now make a beefier small Pan & Tilt that will rotate up to 360 degrees or more.

This P&T can have two configurations, one with just the tilt plate which should work with the Mobius, Mobius Mini, Foxear and Runcam style cameras. The second configuration includes a simple FPV camera snapped into the integrated mount. The FPV camera shown is a 1000TVL Banggood camera which is 17mm square.
- Assemble the Small Gear pivot bolt, large gear and Pan Servo on the Servo Plate
- Assemble the Small Gear, Mount Base, Camera plate and Tilt Servo
- Mount the Servo Plate assembly on the plane
- Add the Large Gear and tilt assembly
- Test and Fly!
