Mach Frame's body earned a Merit Award in the same 2018 Design Contest, and takes an unusual construction approach: the body is built from a main shell plus three separate frame components, styled after high-speed motorcycles and jets. Metallic stickers are included to finish the design. It shares Razorback's aero-side-stay FM-A chassis, moulded here in metallic grey ABS with a black underpanel and other low-friction A parts, and is fitted with white A-spoke wheels and super-hard low-profile tires. Unlike Razorback's lower 4.2:1 ratio, Mach Frame runs the more common 3.5:1 gearing used across most REV series base kits.

The two FM-A design-contest cars share a chassis but differ in body construction, wheel and tyre package, gear ratio and published height.
Choose a Mini 4WD FM-A chassis kit with front-motor handling in mind. Confirm the body, parts fitment and event rules before planning a setup.
