2.4GHz Tactic™ Radio System

The 2.4GHz system in the UL-1 is hard to beat for convenience and control. 2.4GHz tech makes it virtually interference-free and supremely dependable and on-board gear is factory-installed for time-saving ease.

Water-cooled, 36-56-2030kV Brushless Marine Motor

The 6-pole, 36-56-2030kV brushless motor is an AquaCraft design created exclusively for the UL-1 and high-speed hauling. Includes gold-plated, 4 mm motor plugs to boost efficiency.

Waterproof, Water-cooled 60A ESC

Inside its aluminum case, the UL-1 ESC is waterproof, water-cooled and capable of handling 60A current loads with ease. While compatible with NiCds and NiMHs, it offers two safety features tailored just for LiPo packs: a "stutter bump" warning at 12V and automatic cut-off at 11.6V.
