What bugs me with the Walker is that nobody has come out with a spring upgrade like the PZIII. With metal tracks and gearbox the things sags like crazy in the back. Several innovative folks have posted how tos but nothing specific as to exactly which spring would work, like a part number from Century Spring Company. I've done it for the airsoft guns, still have some tests to complete when I get the time.
Hey, Swath - the Panzer upgrade springs fit the Bulldog. So far I've replaced the rearmost springs and it's a lot better, but still droops a bit on acceleration. The Bulldog has weaker springs on the centre road wheels, so the next step is to replace the (very weak) second spring back with the original Bulldog rear spring. If that isn't enough I'll use a second Panzer spring in that position.
... after I've got the StuG going.....
