What makes the RC4WD Bully II MOA crawler kit competition-ready?

The RC4WD Bully II MOA crawler kit is built with premium materials and precision engineering to meet competitive standards. The CNC aluminium axles feature hardened steel gears, full ball bearings, and clockable C hubs for maximum adjustability. The dual motor MOA layout enhances control and stability, while the carbon fibre chassis and titanium links reduce weight without compromising strength. Every component is designed to perform under pressure, making this crawler a true contender.

Is the RC4WD carbon fibre crawler chassis durable enough for extreme terrain?

Yes. The RC4WD carbon fibre crawler chassis is crafted from high-quality carbon fibre and delrin materials, offering a perfect balance of strength and weight reduction. Its high-clearance design allows the crawler to navigate jagged rocks and uneven surfaces with ease. Combined with aluminium shocks and titanium links, this chassis delivers the rigidity and flexibility needed for competitive crawling.

How does the RC4WD MOA crawler with titanium links improve performance?

The RC4WD MOA crawler with titanium links is engineered for optimal drive-line angles and articulation. Titanium construction ensures durability while maintaining a lightweight profile. These links work in tandem with the 4-link front and rear suspension to provide superior control and responsiveness on technical terrain. Whether climbing, descending, or side-hilling, the titanium links contribute to a stable and agile performance.

What’s included in the RC4WD ZK0056 competition crawler kit?

The RC4WD ZK0056 competition crawler includes the full Bully II MOA chassis, CNC aluminium axles, beadlock wheels, advanced compound tires, aluminium shocks, titanium links, and Lexan body panels. While some components may arrive pre-assembled, users are advised to check all hardware and apply thread lock where necessary. The kit requires approximately 2–3 hours of build time and is designed for customisation and tuning.

What electronics are required for the RC4WD 2.2 MOA crawler chassis?

To complete the RC4WD 2.2 MOA crawler chassis, users will need a motor (35T, 45T, or 55T), Rocker Dig II electronic controller, a 2-channel or higher radio and receiver, a Twister high torque metal gear servo, and a compatible battery (2S–3S LiPo recommended). A charger suited to the battery type is also required. These components allow full control of the MOA system and unlock advanced crawling functions.

Is this the best RC4WD crawler with carbon fibre and delrin parts?

For serious competitors and hobbyists alike, this is the best RC4WD crawler with carbon fibre and delrin parts available today. Every element—from the beadlock wheels to the hardened steel gear set—has been tested and refined by the RC4WD Crawler Team. The result is a crawler that performs reliably across diverse terrains and conditions, offering a premium experience straight out of the box.

Is the RC4WD crawler kit with alloy shocks and beadlock wheels customisable?

Absolutely. The RC4WD crawler kit with alloy shocks and beadlock wheels is designed for endless customisation. From optional knuckle weights and steering upgrades to alternative motors and body panels, users can tailor the crawler to match their style and performance goals. The modular design and high-quality components make it a flexible platform for innovation and experimentation.
