The molded-in center tub section keeps all on-board gear high, dry and easily accessible. It also enhances performance: it improves stability by keeping the CG low and braces the hull against distortion. |
A custom aluminum water jacket cools the motor, boosting performance. It’s included in the UL-1 and a direct fit for all other 36 x 56 motors. |

The strut and tapered, 2 mm turn fin adjust to fine-tune performance to conditions. Like all other aluminum parts, they’re CNC-machined and black-anodized for durability and lasting looks. |

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 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!

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. |
| 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. |
