Modular Platform System (MPS)

Probably the most popular vehicles to build MOCs are the Supercars.
We all love cars and the more fast and sports better, but if someone wants to make a Technic Supercar in big size and some complexity (scale 1/10 is the most used) and you don't have a good knowledge of the techniques, build it can be very complicated and end up as hopeless.


This system was created with the idea of ​​helping all those people who want to make a supercar at approx. scale 1/10 and still not have enough knowledge to start, or want to make a car with more advanced specs as Ackerman steering, camber angle and do not know how to do it.

What is a Modular Platform System?

A modular platform system is a set of mechanical elements 100% compatible with each other to suit your needs.

In this case the system haves of three elements: front axles, central chassis and rear axles.
These elements are designed so that you can combine as you like, you choose the front axle you want, the frame that you like and rear axle, join it directly and you have your perfect base for your Supercar!!


All axles are designed and tested for use 68.8x36 ZR tires which are very common and good aesthetics.

Elements description

Front Axles (code: F)

Standard design, rules for a 100% compatible axle with all chassis:

- The total width with wheels 68.8x36ZR has to be 25 studs (19 without wheels)
- The distance between the start of the chassis support point and the center axle of the wheel must be of 7.5 studs.
- The axle only can be attached to the chassis through the support points.
- The drive shaft must enter into the chassis by the center and 3 studs high.
- The drive shaft has to turn left when the car goes forward.

Recommendations for construction:

- Best if the steering column is on one side
- Be able to convert to right steering wheel easily
- Suspension movement between 1 and 2 studs
- Free space to the floor between 1 and 2 studs


Also each axle will have a Index card like this:

Standard: Y/N ->why?
Max. shock adsorvers allowed: max. shock absorvers you can put for each wheel
Space for an auxiliary transmission under the differential: Y/N
Easy conversion to right steering wheel:Y/N
Advanced steering ans suspension geometry:
 - Ackerman steering

 - Camber angle

 - Caster angle

 - Kingpin inclination


Notes: Another information about the axle


Chassis (or Frame) (code: C)

Standard design, rules for a 100% compatible chassis with all axles:

- The front support points must be like this picture:


- The rear support points must be like this  picture:


- The chassis can not continue out the start of support points, like this picture:



- It must have space to connect the drive shaft of both axles



Recommendations for construction:

- Find the best rigidity but using minimum space
- Try to change the length(and therefore the wheel base) was as easy as possible


Also each chassis will have a Index card like this:

Standard: Y/N->why?
Wheel base: Total wheel base including axles
Width: total width od the chasis
Strength test:
 - Load
 - Torsion
Notes: Another information about the chassis.

Rear axles (code: R)

Standard design, rules for a 100% compatible axle with all chassis:

- The total width with wheels 68.8x36ZR has to be 25 studs (19 without wheels)
- The distance between the start of the chassis support point and the center axle of the wheel must be of 5.5 studs.
- The axle only can be attached to the chassis through the support points.
- The drive shaft must enter into the chassis by the center and 3 studs high.
- The drive shaft has to turn left when the car goes forward.

Recommendations for construction:

- Suspension movement between 1 and 2 studs
- Free space to the floor between 1 and 2 studs


Also each axle will have a Index card like this:

Standard: Y/N->why?
Max shock adsorvers allowed:
Advanced suspension geometry (Camber angle):
Notes: Another information about the axle

You can download all axles and chassis in only one link: Download ( )

Comming soon I will add some axles and chassis, and move this post to a new page inside this website, you will can see it in the top of the page. Stay tuned!!

by the way im in 7th grade and im just a kid so help me out here

Hola sheepo te llevo siguiendo desde hace tiempo y tus creaciones son simplemente increibles,estoy intentando hacer el sistema modular pero mi pobre ordenador no soporta el programa sr3d.¿crees que podrias subir las instrucciones en pdf?.e que un gran trabajo para ti pero la esperanza es lo ultimo que se pierde.

Jacob Eriksson said...

Just made a chassis module that is 2 studs thick!

Please help me, i downloaded all axles and chassis, and cant open the file... sheepo help

Sheepo said...

To open the files you need SR3D builder software. Search it in google...

Thanks :)

how can mac users use this ?

Sheepo said...

Go to Instructions page and read the info to MAC users.

Hey Sheepo. You wrote that the axles should be 25 studs with wheel. 5 studs is diff holder and the diff, 12 studs u joints, 2 studs the hub carrier, wheels 6 studs. But in your own cars, with brakes, they will be 29 studs. Is it still standard?

Sheepo said...

Yes, it is. The wheel hub and the final end of the u-joint is actually inside the wheel. I can build without strange solutions, axles with brakes in 27-wide, and without brakes in 25-wide(like this MPS)
