Since the RGT Challenger was launched at the end of 2022, it has been recognized by the market for its powerful configuration and superior performance. To further improve and enhance the performance of Challenger, RGT will launch an upgraded version of Challenger to match the market demand. Model number: EX86170PRO. The upgraded Challenger is powered by Hobbywing brushless FOC system (WP Fusion BLSYS for Crawler-540 SPEC-RTR), driven by magnetic orientation control, with strong low-speed torque and excellent linearity, and the motor runs smoothly and quietly with excellent waterproof and dustproof function, easily cope with all climates and terrains. BEC output of 7.4V/3A brings greater torque output for high-voltage servo. The upgraded version aims to make the whole vehicle more light, adopting a nylon portal axle and spiral main gear. PRO version retains the two-speed transmission, DIG transmission, front drive and four-wheel drive modes, and rear winch,  and adds the electric disconnection of the rear anti-roll bar. The five servos are all equipped with metal gear, and the steering servo changes into a 35KG steel gear CNC metal shell servo. The brass front steering mount cover is assembled within the factory, increases unsprung weight, and improves the ultimate climbing performance. Updating with a larger diameter metal shock absorber, the shock absorber axis adopts a nano-titanium plating process, which improves the smoothness of the shock absorber and gives the car a better movement posture. In terms of appearance, Challenger continues to use the original design and adds the cab and trailer, and the multi-level spraying process inside and outside the bodyshell, better prevent the paint from falling off due to friction. Install anti-roll cage posts inside and outside the bodyshell, to improve the impact resistance.

Features:

• FOC System:
  • The integrated design of ESC and motor greatly reduces the overall volume and weight and makes the layout and wiring of the carframe simpler and more convenient.
  • Low-speed torque is strong, and low-speed linearity is excellent.  The motor runs quietly and smoothly.
  • The protection grade of the whole set of power is IP67, with excellent waterproof and dustproof performance, easily coping with various climates and site environments.
  • Intelligent torque output and speed closed-loop control, fully experience the cruise control and steep slope slow descent function.
  • Multi-stage drag brake force adjustment, the maximum drag braking force is about twice that of ordinary brushless power, providing super parking capacity on a ramp.
  • Multiple protection functions: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection.
  • It supports an LED setting box to set ESC parameters and has an independent parameter setting interface which is integrated on an electronic switch, making setting parameters more convenient.
• Deceleration system:
  • LCG & Reverse Drive, #45 steel reduction shaft with metal gear, improve durability and reliability.
  • High-Low 2-speed shift, DIG rear axle locking, bring smaller turning radius, compatible with disconnect and lock front drive.
  • CNC aluminum T6 motor mount, compatible with 17T~21T pinion.
• Front and rear axle structure:
  • CNC spiral steel teeth, with higher precision portal axle, the car chassis has better passability.
  • The deceleration gear of the portal axle is all made of powder steel, the front steering mount cover is made of brass counterweight to increase the unsprung weight and optimize the proportion of counterweight.
  • Servo mounted on axle, C caster, and steering mount use impact-resistant nylon.
• Servo:
  • Five 7.4V splash-proof metal gear servo.
  • The steering servo adopts 35KG all-metal gear.
  • 25KG - 360 degree metal winch servo, hidden conduit steel wire. The steel wire of the original winch could be stretched up to 90CM, and support the stretching weight up to 15KG.
• The Transmitter unlocks the anti-roll bar. In the locked state, effectively enhances the stability of vehicle turning, reduces the body roll angle, and enhances vehicle handling. In the unlock state, effectively increase and release the up-and-down stroke of the suspension, and enhance the passability of the vehicle.
• Large tube diameter metal shock absorber, the shock absorber axis adopts nano-coating, more hard, collision-resistant, and smooth.
• 9-inch electroplated wheel hub simulation design, the new tire increases the width and tread depth, totally improving the climbing performance.
• The whole car uses metal gear, high-precision rubber cover bearings, and steel central CVD. Smooth transmission performance, no worry about sweeping and broken shaft during all kinds of operation.
• PRO version, the bodyshell uses a new spraying process, and matte effect, with scratch-proof, easy to clean, and other advantages. The new edition adds decorative accessories parts such as the interior cab and trailer Available in two colors (dark rock gray/army green).
