This is the Aquacraft UL-1 Superior FE 2.4GHz Ready To Run Hydroplane. Until the UL-1 Superior, there had never been a LiPo-ready hydro that included both brushless power and 2.4GHz dependability. The UL-1 Superior was designed in the U.S.A. to deliver today's best in cutting-edge control and competition-quality performance and features. That includes a hand laid-up fiberglass hull optimized for racing and brushless power by Mike "Grimracer" Zaborowski, winner of multiple national titles!
