modelbob71 I think you'll find that old gearbox used as a twin setup has a lot of torque and it is very sturdy. I remain a big fan of these,
there's part of me that doesn't like throwing things away and if they can be re tasked so much the better.
I've run my original Sherman a lot using the clutch mechanism since I first bought it. Over the years it's been the butt of any number of jokes
at local club events. It's the Timex of tank models. I haven't the heart to upgrade it; I just leave it as is although I did put in a turret drive of my own doing.
The plastic caps split now and then or fall off. I may one day rework the running gear just to prevent that. It's slow speed makes it a joy to drive through
obstacle courses and village settings. It's a 'noncombatant' tank I just enjoy driving....very nearly 40 years of driving -not a bad return on the $99 it cost
new when I got it. That's what they sold for.
