Modular Platform System (MPS)
About this creation
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 (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) (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 (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

Comming soon I will publish some axles and chassis, you can see it in sheepo.es

Quoting Timothy Dillman Is there any chance that you might make some axles that have the brake disks and such?
I though about that when I designed the MPS, but this that scale(25sutds wide) is not possible include brakes, and if I move the MPS to a bigger scale the axles are much more complex with many new variables, so the work will be huge...

Quoting the ant am i the only one that cannot view it in ldraw? i mean, all the parts are there but they are invisible. anyone know how to fix this?
Do you have change the file extension? In any case you can open it with SR3D builder ;)

Wow, that's a great tutorial. The modular chassis is just awesome. A great idea and very well built. Great job and thank you for the instructions! :-))

Great guide, now everyone can build at least nearly as well as you.

Excellent post. I have been threatening to build a supercar for ages. When I eventually get around to it I will come back for reference. Very educational and useful.

You're brilliant!!! This is just awesome!!! Could you post the instructions? I would love to have them.... :-)

Quoting Magic Number 3 Not too sure how you do it, but its flipping awesome. I don't get how you design a chassis like this ending up with a perfect design, leaving room for so many other features. Grand ma friend!! Grand!!
I know that now this is a bit confused, but when I start to publish the axles you will can understand it perfectly ;)
