Greyscale Racing – MRCG


Introducing the MRCG: A pan chassis aimed at open-class racers who need a lower CG, more responsive handling, and more tuning options than a standard Mini-Z.


This Mini-Z MR02-based chassis has the following design features:

– Mid-motor configuration for agile handling
– Narrowest battery configuration possible to increase responsiveness
– Dual flex-plate suspension similar to Mini-Z F1
– Compatability with many rear suspension configurations: side springs, tri-shock system, disk damper, oil damper, or any combination of those
– Battery pack placed far more rearward than in Mini-Z MR02
– Adjustable weight bias by shifting battery pack fore and aft
– Electronics plate cinches down on any AAA or lithium-polymer pack that fits
– Unique 3-piece front end allows ride height to be adjusted fully independently of spring preload and front end maintenance without kingpin removal
– Thin fiberglass tierod and electronics plate, lots of Delrin and minimal hardware used in order to keep chassis weight low
– Compatability with many servos and electronics packages
– 98mm wheelbase

Parts included:

– G10 fiberglass chassis pieces: Main chassis, Front lower bulkhead, 0°, -1° and 1° tierods, Electronics plate, Rear body/damper mount, Body mount clips (2), Flex plates (2), Rear pod bottom plate, Rear pod top plate (for disk damper), Rear pod top plate (no disk damper)
