Crossfire 3-Axis Gimbal - Runcam2

thingiverse

I made some significant modifications to the original battery tray and designed a custom mount that allows the yaw motor to be positioned directly in front of it, elevated slightly. Next, I crafted an arm connecting the yaw motor to the roll motor. After disassembling my 2-axis gimbal - which is actually a remix of MikeyB's design - I repurposed its components for this project. The first iteration of the setup exhibited extreme shaking and vibrations, but with the help of fellow members from the rcgroup, we discovered that the tray with the gimbal positioned in front was essentially a cantilever, causing mechanical resonance that led to the excessive movement. We determined that the battery tray and top arm were not stiff enough. To address these issues, I reinforced the tray's front section, shortened the motor mount, and made the arm more rigid - all of which proved to be effective solutions. You can see the improvements in action by checking out the video linked below: The unedited footage wasn't stabilized post-production. https://youtu.be/ZOjSq3KYMQc My gimbal controller (STorM32) is mounted on top of my flight controller, just as it is with the original crossfire setup. I'm also using MikeyB's skids in conjunction with the Skid Skids and Arm 3.0 designs from Thingiverse. As shown in the attached image, these PID settings have worked well for me so far. Update: Since the project has been successfully completed, I've removed the "Work in Progress" status.
