Aquacraft Models RTR Remote Control RC Boat: UL-1 Superior Brushless Electric High Speed Hydroplane

The racing RTR with all the extras – and no equals!

Capable of 65+ mph sppeds!

  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!                                                                                                                                      Modeled after full-size UL (Unlimited Light) hydroplanes, the UL-1 features exhaust pipes on the upper deck and rearview mirrors on either side of a painted windshield.                                                                                                                      Created for the UL-1, the 6-pole brushless motor is virtually maintenance-free, extremely efficient and amazingly fast. A CNC-machined water jack turns performance-robbing heat into cool-running perfection.                                                                                                                           

 Like the motor, the controller is water-cooled, waterproof and LiPo-compatible. It provides a stutter-bump warning when power drops to 12V, and cuts off power automatically at 11.6V.                                                                                                                                         

Magnets help align the canopy during installation and hold it afterward.                                                                                                                                                The molded-in center tub is spacious, waterproof and easy to clean. Its depth and shape brace the hull against distortion and lower the CG for more stable running. Adding radio box tape creates a waterproof seal between the hull and hatch.                                                                                                                                                                    The strut adjusts, so you can change prop depth and angle to meet water conditions. The drive system combines a strong 0.150 flex cable with a standard 3/16″ prop shaft.                   

GrimRacer hardware is designed to take punishment in stride and coax the last bit of performance from every boat. All aluminum parts are CNC-machined and black-anodized, for top performance and lasting good looks.                                                                         

The leading edge of the 2 mm turn fin is tapered to cut cleaner and reduce drag. Like the strut, it’s adjustable for performance-tuning.                                                                                                                                                                                                       Breakaway fins appear molded into the hull, but actually attach with 2-sided tape. They detach under stress to prevent damage and float so they’re easy to find and retrieve.

TTX300 3-Channel 2.4GHz Radio

Lightweight and comfortable, the TTX300 offers easy operation and some nice extras. Its third channel can be programmed to control any auxiliary function, including the operation of scale accessories. The TR325 receiver has a built-in fail-safe function; if the signal is lost, it returns the throttle servo to center, preventing runaways and damage to people and property. Endpoint adjustments on the steering and throttle channels let you control how much each servo is allowed to move—a feature that protects gear trains and offers new drivers more control over the throttle. Variable rate steering helps, too, by allowing drivers the chance to fine-tune response to their skill or preference. Other features include: trims, an internal antenna and fast, easy push-button linking.
