The Redcat Ascent-18 APEX is a 1/18-scale, four-wheel-drive brushless crawler designed for precise low-speed driving over technical obstacles. This entry is for the metallic red APEX variant, not the original brushed Ascent-18 or Scout II version. It references Amazon ASIN B0FTTJY6Y1.
Chassis and running gear
The APEX uses a low center of gravity carbon-fiber chassis with a forward motor layout, angled skid plate and redesigned wide high-steer portal axles. Factory-installed brass components at the front axle help place weight over the front tires. The truck uses an optimized ring-and-pinion ratio, bearings throughout the drivetrain, 1.3-inch three-piece beadlock wheels and aluminum-capped oil-filled shocks.
Electronics and included equipment
The manufacturer specifies the Hobbywing HW-1621 3500KV outrunner with a WP-Mini24 2–3S capable speed controller, a 4kg waterproof metal-gear servo and a four-channel 2.4GHz transmitter. The standard kit includes a 3S 11.4V 200mAh LiPo battery and USB charger. Four AA cells for the transmitter are purchased separately. Use the supplied charging guidance and never charge lithium packs unattended.
Dimensions and fit
Published dimensions are approximately 222mm long, 143mm wide and 98mm high, with a 156mm wheelbase and 38mm ground clearance. Most existing Ascent-18 hop-up parts are compatible, but the APEX has redesigned axles, frame and other components, so check part numbers before purchasing replacement parts.
Who should consider it?
The Ascent-18 APEX is most appropriate for enthusiasts wanting a small brushless crawler with more grip, articulation and low-speed precision than a typical toy-grade RC truck. It is not intended for high-speed dirt bashing. Confirm the red variant, package contents and availability on the selected retailer listing.
