vkyopwnsall posted a 6-image Flickr photoset of "The MST001 Micro Scout Tank is the smallest possible full R/C tank. Powered by two M-Motors and featuring a 1:0.6 gear reduction for added torque, the MST001 can scout anywhere with ease. With a size of only 8x5x3.5 inches, the tank is almost unnoticable!"

[NOTE: His reference to a "Micro Scout" has nothing to do with the Lego 32344c02 "Micro Scout" unit: ]

this is sweet

Nice, smaller seems possible though.

Nice tank! Would like to see a video of it
