UL-1 Superior FE Hydro RTR Yellow (AQUB28YY)

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!

• Hull: Lightweight painted fiberglass with molded-in center tub section that houses the motor, batteries and radio equipment, breakaway fins detach under stress to prevent damage to the hull, attach with two-sided tape and float for easy retrieval
• Motor: AquaCraft 6-pole 36-56-2030kV brushless marine motor created exclusively for the UL-1 and high-speed hauling, 4mm motor plugs boost efficiency
• Radio: Tactic TTX-300 2.4GHz SLT system, 3-ch pistol grip transmitter with steering and throttle, and steering trim adjustment, Tactic TSX20 standard servo for rudder control, Tactic TR325 3-channel receiver
• Electronic Speed Control: Water cooled, waterproof, 60A for LiPo usage, a "Stutter Bump" warning at 12V and an auto cut-off at 11.6V insure low voltage protection, ESC is also NiCd and NiMH compatible
• Strut: Black anodized CNC-machined aluminum, adjustable to change prop depth and angle to match water conditions
• Turn Fin: 0.08" (2mm) thick aluminum with tapered leading edge to reduce drag, adjustable for top performance
• Cowl: ABS plastic with magnetic locking system
• Propeller: 3-blade 40mm FRP
