Caliburn is a 1lb shell spinner for the US antweight class. The design is a bit unique since it will feature interchangeable teeth - a set focused more on knockback with a slightly outward rake angle, and a set focused on weapon engagement with a slightly inward angle. The weapon is powered by a SunnySky X2204S 2300kv Outrunner via a 1.5:1 ratio pinion and spur combo. The wheels are Fingertech Mini Sumo wheels for maximum grip, driven by Kitbots 500rpm Ant motors. The weapon teeth are 3D printed steel from Shapeways, the outer shell is Matterhackers Nylon X, and the top disk, chassis, chassis cover and shell retainer are Alloy910 Nylon.
