The UL-1 is the racing RTR with all the extras — and no equals! The hull and hardware are GrimRacer designs. The radio is a cutting-edge TTX300 2.4GHz system. The 2030KV brushless marine motor and 60A ESC are water-cooled, waterproof and AquaCraft originals. And the UL-1 is not only legal for NAMBA and IMPBA competition, it’s perfect for LiPo battery power!
