Wrong tracks. [] The M-26/45/46/47 used a 23 inch wide track. the M-48 series went to a wider 28 inch track (T-97) with the added width outside. (Sort of built in track extension as in Shermans.) This not only added a lot more strain on the engine (same engine with 4 tons extra) but cut down the maneuverability of the M-48. Turning the M-48 used a lot more gas, especially on paved roads.

That Century 21 has the wrong tracks...last M-48 to use steel combat track was the M-48A1...from then, the US used only rubber chevron track. The cal 50 barrel should also be removed from the cupola and the hole stopped up. The external pedestal was welded on for the external cradle mount because none of the cuploa mounts worked until the completely redesigned later M-60s. The problem with the M-1 series based cuploas was that the cal 50 laid on its side and always jammed after a few shots. Even if it did fire, the TC only had 4 trays of 50 rds each ready to load.[:'(]

It's a a good attempt to get RC tanks into the VN era....what is needed now is a PT-76 and early T-54s. Lots of modeling fun possible on this one. Nice idea and Phil can get it running.
