Paul -
   The pads I used are 3/4" thick by 3-5/8" wide by 2-3/4" long, spaced 3" 
on center.  The "teeth" are 1-5/8" square and 3/4" tall, not tapered at 
all.  (1/5th scale, remember, and it's not TTS, but this info might help 
anyway.)  Once in a while a road wheel will ride up on the "tooth", but 
it's not a problem - it either rides all the way over, or falls off the 
edge and makes a big noise.
   What IS a problem is when I'm trying to climb a big obstruction at an 
angle - the whole track will shift sideways so ALL the road wheels ride on 
the teeth, and I'm sure that if I keep it up it will either break the track 
or throw it completely.  I believe taller teeth would solve the problem, 
but then I'd probably have to taper them to prevent ride-ups.

I read somewhere that the "teeth" are actually called "bells", but I can't 
remember where I read that!  Has anyone else ever heard these things called 

The distance between the track and the hull could be determined by a 
front-view drawing.
