Inspire 2 Propeller Guards are crafted with 12k pure carbon fiber mixed with high-strength epoxy resin. They're not only light but also 50 times more durable and 100 times more rigid than standard engineering plastics, making them exceptionally hard to break or deform. Small and easy to mount and detach, these guards protect the propellers from colliding with people and objects, providing an additional layer of flight safety. Consider when flying at particularly high speeds, the propeller guards may only have a limited impact on reducing damage from collisions. Always fly with caution and mind your surroundings.
