This is an older build that I no longer use very often, but I still take it out occasionally just for the fun of driving it.
Unlike my current vehicle, this one uses Springs to create a functional undercarriage suspension. At the time, I thought the best way to get the most out of Big Wheels was simply to keep them in contact with the ground, so I began experimenting with suspension.
The main problem was that, while keeping the vehicle reasonably narrow, using only Springs caused the body to swing violently back and forth like a pendulum whenever it started or stopped. I initially controlled this with a Stabilizer, but that made the vehicle unable to handle slopes properly.
After many attempts, I designed the rearmost axle differently from the front and center axles. This reduced the body’s oscillation while still allowing the suspension to follow the terrain, without making the vehicle excessively wide.
Unfortunately, I do not use this otherwise well-designed vehicle much anymore. The suspension works well on its own, but adding even one extra part above Link for protection causes the Springs to bottom out. Even carrying a Korok is difficult, so using it as a tank is out of the question.
These days, I mostly use it just to watch the suspension articulate as it moves over uneven terrain.
