RE: How does torsion suspension work?
My Asiatam PzIII bars are perfect, but over time, they weaken. I now store the tank on blocks to take the weight off the bars and have noticed an improvement in performance. The KV-1 hull is a different story. Mine came to me with the rear swingarms fully compressed and they never really recovered. I switched the bars around until the front & rear were stiff and the middle were softer. With all the weight in the butt, I had to install a spring inside the rear stop to get it to sit level. This works great, but when the rear bottoms out, it'll bounce just a little.
