Re: Tread Spacing on the TTS [TANKS]

[<sthutch-at-charter.net>]

Well I finally got the suspension finished.  I thought it was getting way out or 
hand, but it turned out ok.  I loaded up my hull with everything that I could weight 
with my fishing scale, which came to 86 lbs, and added my 35-40 lbs child to the mix 
and the hull held it just fine.  Each of the road wheels still had all the movement 
that I intended.   (That really suprised me!)  I thought that it would ride much 
lower than it did.  Well, now for the fun of the track.
