Bang Bang Flip Car has a light, whole-layer design, with 80% of the plane weight sitting below 20 cm, making the structure stable and non-overturning in four directions at 15o. The integrated welding structure, without screws and joints, allows reliable and long-term use. The frame is made of 7 series aviation-grade aluminum alloy, and the wall thickness is unusually greater than 3.5 mm. The overall closed honeycomb structure scheme has strong impact resistance and fatigue resistance. Omnidirectional wheels. Unique bearing sealing technology permitting no water and dust nor oil leakage. Full-micron-level machining precision, self-developed foldable structure, the lowest price.
