The Redcat Ascent-18 APEX, a high-performance 1/18 scale brushless rock crawler built for serious RC enthusiasts who crave precision and power in a compact form. Building on the success of the original Ascent-18, the APEX features over 80% of its platform reimagined to deliver next-level crawling capability. At its core is a carbon fiber low center of gravity (LCG) chassis, engineered for exceptional strength and stability across technical terrain. The newly designed WIDE HS portal axles dramatically improve steering radius while increasing ground clearance, giving drivers the edge on steep and uneven surfaces.
Performance upgrades come standard, including overdrive gears, an optimized ring and pinion gear ratio, and strategically placed brass components such as the front outer portal boxes and differential cover to enhance traction and balance. Ball bearings throughout the drivetrain ensure smooth, efficient operation, while a 4kg metal gear micro servo provides precise control when navigating tough obstacles. Powering the APEX is a HobbyWing brushless motor system paired with a 3S 200mAh LiPo battery and a convenient USB charger-everything you need to hit the trails right out of the box.
The body arrives in a modular two-piece cab-only configuration, with an optional bed attachment for easy customization. The APEX combines rugged performance with refined styling. Aggressive high-grip crawler tires mounted on beadlock wheels give drivers the confidence to tackle challenging terrain with ease.
Like its predecessor, the Ascent-18 APEX is compatible with most Ascent-18 hop-up parts, allowing enthusiasts to expand and personalize performance even further. Whether you're upgrading your rig or diving into the world of micro crawlers for the first time, the APEX delivers a premium experience in a trail-ready package.
