After visiting a lowrider show, I wanted to build my own lego version, and used the legendary 8448 super car as a model. My first attempt a few years ago was a complete failure, but now I have rollin' 3 wheel motion!
About this creation
A shot of the car with the trunk and doors open. Normally, dampened shocks would open the gull wing doors, but I have used pneumatics for them instead.
Each wheel has its own pneumatic cylinder replacing the original shock absorber, giving the car complete independant control over the height of all 4 suspension set-ups.
Now standard in all my pneumatic models - a compressor with 2 pumps out of phase supplying air pressure, with a small cylinder acting as a limit switch.
Open the trunk and we can see the valves to work the wheels and doors.
Shown here with the wheels removed for clarity are the front and rear wheel suspension builds in detail, to explain how the pneumatic cylinders operate.
After buying the 8448 set on ebay, some pneumatic parts and motors, and a few little bits off bricklink, I found this easier to build than my other models; which was a pleasant surprise. The hardest part was building a structure around the compressor which would also hold the pneumatic cylinders that operate the doors.
The rear wheels took some trial and error, I eventually decided to make the suspension arms longer so the drive shaft made from universal joints can flex enough. The front wheels were rather simple. After that, I simply spruced up the colours in a few areas.
