Prototype Test

This is a quick test that displays two winding modes - standard strafe and simulated scatter winding. The annoying rattling noise is a makeshift spool holder off-camera, and vibration on the 3D-printed PLA chassis. The production model will be significantly quieter - 2.5mm steel chassis and motor dampers have been added to the design. Please note that this is an early, 3-D printed prototype test - the production machine has undergone months of refinement. A new video will be uploaded soon!
