UDI Mosasaurus UDI-018-GY 22" Brushless High Speed RC Boat – Grey

The UDI Mosasaurus UDI-018-GY is a high-performance 22-inch brushless RC speed boat designed for exciting high-speed action on the water.

Powered by a 3100KV brushless motor and supplied with an 11.1V 2500mAh 3S LiPo battery, the Mosasaurus can reach speeds of approximately 40km/h.

Featuring a rigid deep-V ABS hull, water-cooled electronics, cable-drive propulsion, self-righting capability and high/low speed modes, the Mosasaurus combines impressive performance with features designed to make high-speed boating easier and more enjoyable.

Powerful 3100KV Brushless Motor

The Mosasaurus is equipped with a 3100KV brushless motor designed to provide strong acceleration and high-speed performance.

The motor uses an innovative water-cooling system that directs cooling water through a sealed motor jacket, helping transfer heat away from the motor during operation.

This allows the boat to maintain performance during repeated high-speed runs.

Water-Cooled Marine ESC

The waterproof marine ESC features an integrated water-cooling system and aluminium heat sink.

Protection functions include:

• Low-voltage detection
• Thermal overload protection
• Voltage overload protection
• Waterproof construction
• Water-cooled operation

The ESC can also be adjusted for different operating conditions using the multi-function control on the transmitter.

3S LiPo Power

The UDI-018-GY includes an 11.1V 2500mAh 3S LiPo battery.

The 3S setup provides the power required by the 3100KV brushless system and allows the boat to reach approximately 40km/h under suitable conditions.

The advertised runtime is approximately 8 minutes, depending on driving style, battery condition and water conditions.

Deep-V ABS Hull

The Mosasaurus features a strong deep-V ABS hull designed for high-speed stability.

The hull is constructed using a layered design that provides additional rigidity around the transom and ride pad while keeping overall weight under control.

The reinforced construction is designed to withstand the stresses produced by the high-output brushless power system.

Self-Righting Hull Design

One of the major features of the UDI-018 is its self-righting hull design.

If the boat overturns during operation, the self-righting function can help return the boat to an upright position, allowing you to get back on the water without having to retrieve the boat manually.

This is particularly useful when running at high speed or performing tight turns.

High and Low Speed Modes

The transmitter provides High and Low Speed modes, allowing the boat's performance to be adjusted to suit the driver and water conditions.

Low-speed mode is useful for learning and manoeuvring, while high-speed mode provides access to the full performance of the brushless system.

Cable-Drive Propulsion

The Mosasaurus uses a smooth cable-drive propulsion system designed for efficient power transfer from the brushless motor to the propeller.

The drive system is designed specifically for high-speed marine operation and works together with the deep-V hull to provide stable and responsive performance.

Navigation Rudder

A responsive navigation rudder provides directional control and allows the boat to make tight turns while maintaining good control at speed.

The steering system is designed to provide precise proportional steering response from the 2.4GHz transmitter.

Low Battery & Out-of-Range Alarms

The radio system incorporates useful warning functions including:

• Low battery alarm
• Out-of-range alarm

These features provide additional awareness while operating the boat and help reduce the risk of continuing to operate when battery voltage or radio signal becomes unsuitable.

2.4GHz Radio System

A 2.4GHz radio system is included for reliable control.

The advertised control range is approximately 100 metres under suitable conditions.

The transmitter provides proportional control of:

• Forward
• Reverse
• Left
• Right
• High/Low speed
• Self-righting functions

Modern Reinforced Design

The Mosasaurus features a clean, modern hull design with reinforced construction around key high-stress areas.

The transom incorporates mounting provisions for the trim tabs, turn fins, rudder support and drive strut, helping keep the interior of the hull clean and organised.

The lightweight ABS construction provides a good balance between strength and performance.
