How to build a custom 3Dprinted RC BMW M3 GTR (e46)?

This is how we did it. With our LEGACY Chassis v.2.1

Were you a teenager and a car enthusiast around 2005 ish? Well, then you’re just like us! NFS M3 GTR We Forever Love YOU 😀
As always we let you be the judge to tell how well we could capture it.
Our aim was to get it as much authentic as possible.

Chassis v.2.1 (BMW M3 GTR)

This is a Legacy Chassis! Click to v.2.3

Chassis dimensions

Wheelbase	270mm
Front Wheel Track	183mm
Rear Wheel Track	183mm

In the name you can see v.2.1 this means it is our 1st generation chassis system the U profile based one.

We strive for an ultimate universal chassis because we wanna use it under many 3D printed car bodies. So that’s why we created the slideable parts.
The chassis is built on a 2 (aluminium) U profile (8×10 mm) with bought and 3D printed parts.
3D printed parts: Housing of the electric motor, housing of the battery, most of the steering system…
Bought parts are:
The suspension (length 60 mm), the different wheel rims with the tires, the servo, the receiver, drive shaft and the differential is from Tamiya, the electric motor (17000 rpm), and of course screws (M2, M3) and the ball joints (M3).
