HSP Racing XSTR PRO Brushless Electric Buggy 2.4 GHz - R-SPEC

Special Edition R-SPEC Design and Upgrades

THe XSTR PRO R-SPEC is the flagship evolution of HSP's iconic electric buggy platform. Designed for enthusiasts seeking both performance and visual impact, this special edition features a series of exclusive red anodised components including front and rear shocks, shock towers, wheel rims, wing, central drive shaft, and upper deck. These parts are not only visually distinctive but also contribute to improved rigidity and reduced chassis flex during aggressive driving. The R-SPEC body shell completes the package, providing a sleek, race-inspired aesthetic complemented by durable polycarbonate construction.

High-Output Brushless Power System

This PRO edition is equipped with a 3300KV FSD brushless motor, engineered for rapid acceleration and efficient high-speed operation. Compared to brushed motors, the brushless design delivers significantly higher torque, faster rotational response, and reduced maintenance.

The motor is controlled via a Hobbywing 50A waterproof ESC, featuring a cooling fan for stable operation under demanding load conditions. Combined with the Fullymax 7.4V 3500mAh LiPo battery, the buggy maintains strong punch from launch to top speed while supporting extended runtimes typical of competitive sessions.

Reinforced 4WD Drivetrain and Steering System

The XSTR PRO R-SPEC features a robust 4-wheel drive layout, supported by high-performance front and rear differentials for superior traction during cornering and uneven terrain. An aluminium central drive shaft ensures consistent torque transfer with minimal loss.

A carefully engineered advanced servo-saver steering system increases steering precision, reduces kickback forces transmitted to the servo, and enhances response time when navigating technical sections at speed.

Fully Adjustable Racing Suspension

The suspension system utilises aluminium oil-filled shocks mounted to aluminium shock towers, delivering excellent damping performance across a range of surfaces. The shocks are adjustable for preload and mounting angle, allowing drivers to fine-tune the setup for jumps, high-speed sweeping bends, or tight technical track layouts.

Together with race-developed suspension geometry, the buggy provides exceptional grip, stability, and predictability during rapid directional changes.

Electronics Protected Against the Elements

To ensure reliable operation in varied track conditions, the XSTR PRO R-SPEC is equipped with a waterproof servo, ESC, and receiver, helping to safeguard internal components from splash exposure. This makes the buggy suitable for damp tracks, puddles, and light off-road environments without compromising control.

2.4 GHz Control System for Precision Driving

The model includes a modern 2.4 GHz radio system, offering strong signal stability, rapid input response, and the ability to operate multiple vehicles simultaneously without interference. This makes it ideal for club-level racing or shared use areas.

Ready-to-Run Platform

The XSTR PRO R-SPEC arrives fully assembled with all electronics installed. Only 8xAA batteries for the transmitter are required to begin operation. Whether used for competitive racing or high-performance recreational driving, this model provides a complete premium-spec solution out of the box.
