Description
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.
- Length 156mm, width 97mm, height 36mm
- Chassis: FM-A (aero side stays), gear ratio 3.5:1
- Motor included, snap-together assembly
- Requires 2x AA (R6/UM3) batteries, not included
