The Challenger PRO is powered by Hobbywing brushless FOC system (WP Fusion BLSYS for Crawler-540 SPEC-RTR), with strong low-speed torque and excellent linearity. The motor runs smoothly and quietly with excellent waterproof and dustproof protection to easily cope with all climates and terrains. BEC output of 7.4V/3A brings greater torque output for high-voltage servo.
The developers also focused on weight reduction, using nylon portal axles with spiral gears. PRO version retains the two-speed/DIG transmission, front drive and four-wheel drive modes and rear winch, but adds an electric disconnection of the rear anti-roll bar.
All five servos are equipped with metal gears, and the steering servo was upgraded to a 35kg steel gear with an aluminum case. The front portal gear covers now use a brass material, to increase the unsprung weight and improve the vehicle climbing performance.
The shock absorbers are upgraded as well, having a larger diameter and nano-titanium plating layer, which improves the damping smoothness and gives the car a better movement articulation.
Challenger PRO uses the original body design and adds multi-level spray paint with a matt finish.
