To further refine and enhance product performance, RGT has introduced the new FOC upgraded version, the &#8220;Challenger PRO,&#8221; to better meet market demands. The upgraded &#8220;Challenger PRO&#8221; features a Hobbywing FOC brushless system specifically designed for crawlers (WP Fusion BL SYS for Crawler-540Spec-RTR). It utilizes Field-Oriented Control (FOC) technology, providing strong low-speed torque and excellent linearity. The motor operates smoothly and quietly, offering superior waterproof and dustproof performance, making it capable of handling various weather conditions and terrains with ease.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"RGT Challenger PRO - Equipped with FOC Brushless Power System\" width=\"660\" height=\"371\" src=\"https:\/\/www.youtube.com\/embed\/fDTBGvSDx5E?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Compared to the standard version, the PRO upgrade retains key features such as portal axle structure, two-speed transmission, DIG transmission disconnect function, front-wheel drive, and four-wheel drive modes, as well as a winch function. Additionally, the PRO version introduces an automatic rear anti-roll bar unlock design. The vehicle is equipped with five servos, all featuring metal powder gears. The steering servo has been upgraded to a 35KG full-metal servo. The front steering knuckle cover is made from brass for added weight distribution, and the new full-metal shock absorbers feature a nano-coating process on the shock shafts, ensuring greater hardness and smoother suspension performance.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"821\" height=\"1024\" src=\"https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504-821x1024.jpg\" alt=\"\" class=\"wp-image-1766\" srcset=\"https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504-821x1024.jpg 821w, https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504-241x300.jpg 241w, https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504-768x958.jpg 768w, https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504-1232x1536.jpg 1232w, https:\/\/www.rcfans.net\/wp-content\/uploads\/2024\/09\/\u6d77\u62a504.jpg 1280w\" sizes=\"(max-width: 821px) 100vw, 821px\" \/><figcaption>EX86170PRO<\/figcaption><\/figure>\n\n\n\n<h3>Exterior Design:<\/h3>\n\n\n\n<p>The upgraded &#8220;Challenger PRO&#8221; retains the classic body design while adding cockpit and truck bed decorations.
