My Tiger T067 also has Christie if you want another view - nothing groundbreaking in my design but it might help to look at another one.

Steve, Thanks for sharing your experiences with the swing arm suspension system. I was wondering, have you had any springs come out of the recessed grooves in the hull? Well, the inventive juices are flowing now. Considering what you've mentioned, I'am going to experiment a bit with a variable rate spring system, perhaps longer springs, stops on the side of the hull, altered shape aluminum trailing arms, etc. I really like the compression spring swing arm suspension system. It seems to be an elegant, yet simple solution to suspension. I'll test out the above ideas and see what happens. Does anyone else have any ideas on the compression spring swing arm suspension system used on Tanks T #040 & T#059? I'll play around and let the group know my findings.

Grant, The design has held up well. The only mods since construction (and which I need to document) are that I added upper stops to the swingarms. This prolongs the life of the springs which were getting distorted due to repeated bottoming out of the suspension (due to my habit of trying to drive over anything at speed). The stops consist of short pieces of fiberglass rod added to inside the suspension springs. The rods were an expedient and if I were to build again from scratch (or during a major overhaul) I'd probably use an aluminum bar bolted to the outside of the hull that would stop the swingarms on the upper arc. Even with the stops the springs still get bent out of shape over time so order extra ones when you finalize on the springs that work best. The non-precision flanged ball bearings I used for the hull side of the swingarms have loosened up a bit since first built, thus the arms have a little play side-to-side, but everything still works well. Overall I'm very happy with the way the design has worked out and would use it again in another tank.
