ARM MONO PLATE
The QAV-S 2 Sub-250 Joshua Bardwell Special Edition is truly unique, featuring 3.5mm thick arms paired with an Arm Mono plate. Weighing just 55g (frame only, without accessories), this design strikes an industry-leading balance between lightweight construction and durability, perfect for even the most demanding applications. The Arm Mono plate enhances rigidity while keeping the configuration light.

ALUMINUM CAMERA PLATES
The Lumenier QAV-S2 Sub-250 Joshua Bardwell frame kit features aluminum FPV camera side plates for enhanced protection and flexibility. It supports both HD and analog cameras, including damped mounts optimized for O3 and O4 Air Unit cameras—offering endless possibilities for your setup! These plates are also backward compatible with the QAV-S 2 Bardwell 5" frame kit.

SOFT RUBBER CAMERA ISOLATION MOUNT
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.
