The fastest frame in the game - ultralight ready. The ULX ultralight was pioneered by the Fire Falcon himself, Dutch. He's been putting this frame through rigorous testing while bringing in some of the best pilots such as PiFly, (oOo), and Infinitee to help him test it out. Get ready for ultralight ultra speed!
