Welcome to RGT

Since RGT Challenger was launched at the end of 2022, it has been recognized by the market with its powerful configuration and superior performance. In order to further improve and enhance the performance of Challenger, RGT will launch totally 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 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 rear anti-roll bar. The five servo are all equipped with metal gear,  and steering servo change into 35KG steel gear CNC metal shell servo. Brass front steering mount cover is assembled with in the factory, increases unsprung weight and improves the ultimate climbing performance. Updating with larger diameter metal shock absorber, and the shock absorber axis adopts nano-titanium plating process, which improves the smoothness of shock absorber and gives the car a better movement posture. In terms of appearance.

FOC System：

*. The integrated design of ESC and motor greatly reduces the overall volume and weight, and makes the layout and wiring of carframe simper and more convenient.

*.Low speed torque is strong,  and low-speed linearity is excellent.  The motor runs quiet and more smooth.

*.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 drage braking force is about twice than ordinary brushless power, providing super parking capacity on ramp.

*.Multiple protection functions: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection.

*It supports LED setting box to set ESC parameters, and has independent parameter setting interface which is integrated on electronic switch, making setting parameters more conveniene.

Challenger PRO continues to use the original design, and adds the cab and trailer, and the multi-level spraying process inside and outside bodyshell, better prevent the paint from falling off due to friction. Install anti-roll cage post inside and outside bodyshell, to improve the impact resistance.
