Re: Stronghold Drivetrain Review
We did a 10WD with all 6" Colsons. The center wheel was dropped 1/8" and the outer wheels were raised 1". The center wheel probably should not have been dropped as our wheelbase was too short and we turned too easily. This drivetrain easily handled all of the defenses, except for the moat - sometime between concept and detailed design, the drivetrain got two inches longer, and too much space was left between the drive wheels. This was my only complaint with the drive, other than weight of course.
We did not run into any issues by not using pneumatic wheels, and we enjoyed the greater traction of Colsons. We may have changed the outer wheels to pneumatic if we had to do it again though, just to be safe.
We used 25 chain with 22T sprockets, and it stretched a lot more than it normally did, but we had no issues with throwing chains or damaging sprockets.
