Features Overview

Lightweight, durable fiberglass hull with matching canopy and removable vertical fins:
Because the hull is lightweight and durable, you can push this hydroplane to max speeds in race condition waters. The canopy, like the hull, is constructed of hand-laid fiberglass. The vertical fins are removable and replaceable. In case of a bad crash, they will simply break away without damaging the hull.

Extreme power from waterproof electronics:
The UL-19 uses a Dynamite® water-cooled 120A, 2-6S ESC that can handle more amperage than needed to run the boat with authority and speed. The new 2000Kv 6-Pole motor features a large rotor that greatly increases motor torque.

Stainless steel two-blade propeller:
An aggressive boat like the UL-19 deserves an equally aggressive two-blade propeller. The UL-19's propeller lets you take full advantage of the hull's performance. It features a high-pitch, high rake stainless steel propeller that produces a tight thrust cone that results in better propulsion and higher speeds that won't overload the electronics. You'll be able to reach speeds on 4S that could only be reached on 6S by other boats.

Interference-free connection:
The included Spektrum DX2E DSMR® 2.4GHz transmitter will provide a clear, precise connection while the hydroplane is on the water.

Aluminum adjustable propeller strut:
Use the aluminum adjustable propeller strut to tune the boat to various water conditions, from glass smooth to windy and choppy. The square-bottom propeller strut allows more precise adjustments by acting similar to a trim tab usually found on Deep-V boats.

Aluminum break-away rudder:
The aluminum rudder features a break-away design that will safeguard the transom if the hydroplane hits an immovable object on the water or runs ashore.

Stainless steel turn fin:
The stainless steel turn fin will keep the boat glued to the water whether you're going straight or full throttle through a turn.
