The Redcat Ascent-18 International Scout II Brushless is a 1/18-scale electric RC crawler with a licensed International Harvester Scout II body. This entry covers the Gold Dust finish, model RER39152, and Amazon ASIN B0FLZQRH7K. It is distinct from the original brushed Scout II and the APEX competition-oriented chassis.
Driving system
A 3450KV outrunner brushless motor and R3C-BL two-in-one speed-controller/receiver power four-wheel drive. Manufacturer specifications include a 2mm flat aluminum ladder chassis, high-steer portal axles, bearing-supported metal gears, machined aluminum spools and aluminum-capped oil-filled shocks. The vehicle’s wheelbase is 155mm and the published ground clearance is approximately 38mm.
Scale appearance
The official Scout II body offers classic grille and window detailing, preinstalled LED lights, a hinged front-tilt mounting system and off-road tires styled after Interco IROK Super Swampers. Its scale-body dimensions (about 265mm long, 126mm wide and 125mm tall) are designed for crawling, not high-speed racing.
Power and preparation
Standard manufacturer packaging includes a 7.4V 750mAh 2S LiPo pack, compatible USB charger and 2.4GHz controller. Add four AA cells for the controller. The manufacturer identifies the factory speed-controller configuration as 2S LiPo only. Do not install a 3S pack without changing to suitable supported electronics, and always follow LiPo charging guidance.
Upgrade and fitment notes
Many Ascent-18 platform hop-up parts can be used, but check whether each upgrade specifies the brushless Scout II version. The forward-hinged body and Portal axle geometry mean generic truck accessories may not fit without modifications.
