Whats the difference between twin motor and double motor ?

The double motor gearbox can be configured with 4 different gear ratios. The twin can only be built with 2.

I have a Tamiya 1:35 scale Sturmgeschütz IV (Kit #35087), what else do I need besides this motor gearbox to make the tank R/C?

From what I can tell from TamiyaUSA your model is basically a static display. You are going to need an RC system (transmitter(s) / receiver(s) ), propulsion (presumably DC motors and possibly but not necessary a gear box like the one you asked about. I would contact someone in the RC model business (RC planes, boats, cars, whatever) to discuss your plans.http://www.tamiyausa.com/items/plastic-model-series-20/1-35-scale-military-miniature-12000/german-sturmgeschutz-iv-kit-35087

how much more narrow is the twin motor gearbox than the double gearbox?

here are the dimensions for twin motor gearbox: Specifications:Size: 75 x 50 x 23 mmShafts: 3 mm hex, 105 mm long.The included FA-130 motors run at 3.0 Volts (4.5 V max)Stall torque: 4.6 gcmNo-load speed: 13,230 rpmCurrent: 0.5 A (each)Maximum ratio: 203:1Open axle space: 50mm each sideSpeed and Torque outputs (approximate), at 3 Volts:Gear Ratio: 58:1, 203:1Speed RPM: 230, 65Torque g-cm: 269, 941 dimensions for double gearbox:size: 70mm x 60mm x 23mm

Will this gearbox match up with the Tamiya tracked vehicle chassis or would I need to pick up the other style you sell that's around $1 more?

I have used those two together without a problem
