Competitive Features in a Ready To Run Package The Redcat Ascent-18 1/18 4WD RTR Brushed Rock Crawler delivers big performance in a compact, trail-ready package. Built with the same attention to quality and value that Redcat is known for in 1/10 scale crawling, the Ascent-18 brings competitive features to the 1/18 scale market. Despite its small size, it’s packed with premium components typically found on larger, high-end crawlers. Fully Ready-To-Run, this mini crawler is designed to tackle challenging terrain right out of the box. High Steer Geometry With Portal Axles The Ascent-18 features redesigned High Steer (HS) geometry that increases steering angle and improves clearance at the C-hubs. Combined with durable portal axles, it delivers greater ground clearance and reduced torque twist for confident obstacle crawling.
