Product Data Table

Design and Build Quality

Full Aluminum Alloy Frame

One of the most striking features of this crawler is its full aluminum alloy frame structure. Unlike traditional steel-heavy designs, this approach reduces unnecessary weight while maintaining strength.

The benefits include:

• Improved weight distribution
• Enhanced durability
• Better handling on uneven terrain

The frame is engineered with precision, offering a true-to-scale appearance that appeals to collectors and enthusiasts alike.

CNC Machined Components

The use of CNC machining ensures that every component fits perfectly. This results in:

• Increased structural integrity
• Reduced mechanical play
• Smooth operation

From the chassis to the suspension arms, every detail reflects high manufacturing standards.

COMMANDER Steering System

Rack-and-Pinion Precision

The COMMANDER steering system is one of the most advanced features of this model. It replicates a real rack-and-pinion mechanism, providing:

• Accurate steering response
• Improved stability
• Reduced steering lag

This system has been refined over years of development, making it a reliable and efficient solution for high-performance crawling.

Enhanced Control

The steering system allows for precise maneuvering, which is essential when navigating tight trails or technical obstacles.

Suspension System and Stability

Full Metal Suspension Design

The suspension system is fully constructed from metal and designed to handle extreme conditions. It includes:

• Independent front and rear setups
