BubbaJoeXX:

You WANT the ones shown, or the NEW ones? I ask because the new ones actually take up less space, and the originals are only 280's - and anything larger won't fit unless you find specific short-can 300+ motors (I tried that too)

Unless you can snag a pack from one of the stored 'collectors' copies, you'll probably be SOL, and if you do get 'offers', they may want as much as DMD's anyway.

Not to mention the gears are the poor Tamiya 'pot-metal' ones, and rarely stood up to use over the 3+ decades that its been out. The 'used' gearboxes often had the optional gears missing - you got either a clutched 1:100 ratio with a central gear-shaft, or a separate-drive setup with two outer gears on a 1:200 ratio (making the clutch pointless) I can post pics of the RT-1601 manual showing this if you like.

As one who HAD the RT-1601 kit (it was NEVER listed as the 56001) I can say its a poor choice over the new gearboxes and the 56014 suspension w/ bearings. Even the HL metal boxes would be better (not to mention CHEAPER) and a HL electronics system could supply more functionality too: traverse (limited but a Sexton did have SOME traverse) and elevation as well as engine noise.

Just my two hundredth-loons.
