Crossfire 3-Axis Gimbal - Runcam2

thingiverse

Basically I modified the original battery-tray and designed a mount to get the yaw-motor fixed in front and up a bit. Then I made the arm from the yaw- to the roll-motor. I took the remaining parts from my 2-axis gimbal, wich in turn is a remix of MikeyB´s gimbal. The first version showed extreme shaking and trembling. Members of the rcgroup helped me to find out, that the tray with the gimbal in front is a cantilever and that the vibrations led to a kind of mechanical resonance which caused the shaking. The battery-tray and the top-arm where not stiff enough. So I made the tray-front thicker, the motor-mount shorter and the arm stiffer - this helped. Have a look at the video. The short footage was not stabilized afterwards. https://youtu.be/ZOjSq3KYMQc The gimbal-controller (I used a STorM32) is mounted on top of the flight-controller (https://www.thingiverse.com/thing:1947094) - as it is with the original crossfire. I use MikeyBs skids (https://www.thingiverse.com/thing:244567) with the Skid Skids (https://www.thingiverse.com/thing:285292) and the arm 3.0 (https://www.thingiverse.com/thing:285292). The PID-Settings in the picture work for me. Update: I removed the status "Work in Progress". This thing works for me as it is.
