SCARAB Beetleweight Hubmotor Drum V1.11

World's First Modular Hubmotor Drum Spinner! User Guide Available Here! Latest Version CAD model here! And you can buy spare parts here.  Specs and Usage The SCARAB drum system with its shaft, bearings, spacers and all weighs under 1lb (440g), with spinning mass of ~300 grams or 0.66 pounds, an immense amount of stopping power! Perfect for beetles looking for crazy weapon power in a tiny package. The effective diameter is 65mm (2.559") with stock teeth, and the drum fits onto a 125mm long shaft, with 102mm between uprights. Use with a 4S LiPo for best results and 268 mph theoretical tip speed. 5S/6S is not recommended.  To assemble your SCARAB for use, you should first solder wires or the included MR30-PW-M connector to the stator PCB (easiest after removing the stator/shaft assembly from the drum). We recommend 18AWG wires or 16AWG if the wires will be over 100 mm/4 inches long. Be very careful not to create a short between phases, as this will damage your ESC! Reassembly: The stacku
