Ah, but it isn't a question of the length of the track changing, but
rather the displacement of the track. I don't have any handy-dandy
illustrations, but if you imagine either the front or rear road wheel being
pushed up (as in driving over an obstacle), then you've just changed
shortened the distance around all the wheels (road, drive, idler, return),
reducing tension. Now, if it's a large obstacle and the hull is pitched up,
then the other road wheels will drop, increasing tension again. Of course
this is all ignoring the fact that you will need some burly spring pressure
to keep the road wheels pushed down when you tension the system. Then again,
maybe I'm just talking out of my ass.
The cogs from that page look to have good compatability with the TTS.
But I think Steve is on to something with the Christie drive system. If
memory serves, the Christie drive puts the drive power to one or more pairs
of the road wheels. That allows the tank to drive even without the treads
on. If the road wheels themselves were powered, then the tension of the
track would be a far smaller issue on a friction drive, as the weight of the
tank itself would give the necessary friction.
One problem that immediately springs to mind with it though is that if
the driven road wheel lost contact with the track (think Mr. Tyng's photo op
with the rocket launcher guy), then that track would be effectively dead.
Maybe drive the front and rear road wheels? Of course, with the Christie
drive you have added the chore of driving a suspended wheel. Probably the
easiest way to upgrade an existing TTS to suspension would be with the cogs.
Sorry, I tend to ramble when I think I know what I'm talking about.

i don't see why suspension won't work with TTS the length of the track can only get less [ i.e less friction ] if the tensioner goes slack not if a road wheel goes up or down ?
