2.0 CHASSIS CONFIGURATION #353015
2.0 Chassis and Servo Clamp is designed to carry servos sizing 35x30x15mm. (Example. Savox 1250MG)
The Advanced Modular Components (AMC7) prototype Concept #7, we will call it "C7". We have done our research on this platform, many hours of development. We welcome you to share and to use this DIY open-source chassis. Our 1/12th Scale 3D Printed RC Racing Car is a modular system chassis allowing you quick-change ride height and rear suspension adjustments with the turn of a couple of screws, this unibody-type structure makes it both exceptionally light and highly durable.
Our MSP-kCart7 chassis design features engineered flex styled racing, kinda like a Go-Kart. Our convienent Axle Block Adjustment Shims (ABAS) offers quick ride height adjustment and headache free setup, depending on any 1/12th scale racing tire you use. Coupled with our Battery Pod - Rear Suspension Modular System (RSMS), is track-tested and drivability-approved.
Welcome to the 8min mains! 😎 🏆
Axle Block and the Adjustment Shims were improved. Ride height positional accuracy was improved for the use of Foam Tires.
The axles quick change center point now allows you to race all tires. New block and shim setups maintain accuracy within 3.4mm to 3.7mm based on what tire brand and/or cut size you choose to run. The list below is a Quick Check to review these simple abc123 ease of use basic block Shims:
0.5mm, 1mm, 2mm. Reminder, ea size shim you use, equal the size to the upper flange.
Review the ABAS Quick Check Tire Size Chart below.... 🍿
Open Tread Tire (+ shim) = Ride Height
*44.8mm Gravity +2mm +0.5mm = 3.6mm
*42mm Excelerate +1mm = 3.5mm
Slicks or Foam Cut (+ shim) = Ride Height
*42mm CRC Cut +1mm = 3.5mm
*40.7mm SJT Cut +0.5mm = 3.6mm
*40.7mm Foam Cut +0.5mm = 3.6mm
*40.5mm Foam Cut +0.5mm = 3.4mm
*40.2mm Foam Cut zero Shims = 3.7mm
Note: Using Shims equal or more then 1.5mm, switch to 10mm flat head and button head screw to prevent damage to the insert.
Please NOTE: this is a reference list only. There can be alternative parts as well. These are the parts I specifically used for my build.

New 2.0 Updates
- •All-new printable front fixed geometry two piece caster and camber control. Allows 4° and 5° caster
- •Front chassis reinforcement for new front suspension pod.
- •Servo position mounted at lowest possible position on chassis to lower front CG.
- •Shifted the motor 1mm closer to the spur, improving overall balance and weight transfer.
- •Rear motor plate and mount reinforced with the addition of a third fastening point.
- •Improved pinion-to-spur gear accuracy. Greatly reducing torque flex to the rear axle.
- •Improved acceleration through new anti flex bracing.
- •New one piece adjustable motor plate.
