Slotcar TankTruck 3180
Necessary things needed to build?
First, I looked at Lego Stores, Legoland Günsburg, and several other shops to find a Lego kit. The Lego kit needed to have a size that was near a scale of 1:32.
I found the Lego City Airport Kit “3180 Tank Truck”.
Now I built the kit and measured primarily the axle width and wheelbase and it looked great.
At the second step, I looked for a suitable slot car chassis and found a used one.
A Carrera 27323 Ferrari F10 "F. Alonso" model with a damaged body. Perfect.
The third step was to design the framework between the Carrera chassis and the Lego bricks. A little bit difficult because the e-motor must be between two rows of bricks. The dimensions required to exchange the control board into a smaller one.
Now I connected the parts: The frame, the cab of the Lego kit, some other Lego bricks and the Carrera chassis.
And at the end, a Lego Slot car Truck was built which is now running along the Carrera race track!
