I think the unspectacular climbing ability may be due to the Pershing having its gear drives and motors at the rear versus the Tiger having its drive unit at the front--sort of a front-wheel-drive tank. Basically a center of gravity problem going on here and the Tiger does better with its forward weight bias. You're on the right track though, and the Pershing should benefit from having some weight added up front.

Gratified that the 'Persh' has yet to throw a track. That's what I'm talking about!!

Great paint job on those tanks. The camo pattern on the "Big P" is real tight. You did real well using those budget products. Great pics too! Wow...
