This is a 3 axis plane gimbal with roll stabilization. I built it using lynxmotion robot linkages and
standard servos which I modified to be continuous. The roll axis is stabilized using a radian
gyro from freefly systems.
The platform is a bixler 2 with a motor mount mod for a larger motor and prop.
This setup has a pilot and then a seperate tx for the camera controls. The pilot can fly using fpv on a
seperate cam or just line of sight.
For version 2 I hope to make the gimbal more compact and better balanced. I also plan to make it
pan, roll, tilt instead of roll, pan, tilt. I also want to stabilize tilt and use cheaper gyros.
Maybe I can just use an existing brushless gimbal system now that they have become more available.
Here is a video of version 1. I've used post stabilization on some of the shots. the gimbal does a good job
taking out big movements and leveling out the camera, but post stabilization was needed to get rid
of the smaller shakes. I think for version 2 I will need to have some sort of vibration isolation between
the camera and the plane.
Enjoy!
Any feedback or suggestions will be greatly appreciated.

I dialed down the slew rate of each axis so that the camera operator could not jerk the camera back and forth and right and left, this would affect the plane a lot before. But now the camera movements are much smoother so it does not affect the plane's stability.
The roll axis shifts the weight of the camera the most but since it is stabilized it always tries to stay upright so the weight doesn't really get shifted around much. You can think of it as the camera being fixed and the plane moving around the the camera.
