RE: Introduction from another newbie [TANKS]

[himself-at-adamwells.net]

Well, I've been considering the idea of how to implement a suspension. After 
looking over pictures of the fullscale version, I'm thinking about using 90 
degree free position torsion springs braced against the return rollers (or a 
post for that purpose in the case of the last road wheels, which lack a 
corresponding return roller). It is a little bit more complex, but should still 
be simple enough.... I'll just have to make sure the springs won't rip the 
return rollers out of the hull.
