The Lumenier QAV-S 2 Sub-250 Joshua Bardwell SE 3" frame kit features a soft rubber camera isolation mount, reducing vibrations for smoother, more stable footage when stabilizing with either on-camera stabilization (RockSteady) or software stabilization (Gyroflow).

3D PRINTS

*The damper inserts should be printed in TPU; you can reduce the walls and infill percentage to help with damping if necessary. Machined aluminum parts will be available soon, and these same damper inserts will work with the production parts if needed.

**This mount is a drop-in replacement for the camera cage on the Bardwell edition of the Lumenier QAV-S 2. The camera cage portion should be printed in something stiff and tough, like nylon or carbon fiber nylon. PAHT-CF is a great choice if you can print it. This mount was also tested in PETG-CF, and it works decently. These are printed parts, though, so remember that durability will suffer compared to machined aluminum parts.

DJI O4 AIR UNIT ADAPTER

Need to adapt your new DJI O4 AIr Unit camera to a standard 20mm wide camera plate? We have you covered! We've designed a few different adapter plates that take the small DJI camera and adapt the mounting plates from 14mm to 20mm, using the same hole positions as the previous DJI O3 air unit!
