Josh, A TTS track (short for Tyng Track System) uses a continuous loop of treadmill or conveyor belting as the main tension member. The "tracks" are mating pads adhered to the inner and outer faces of the belt. Guide horns are incorporated on the inner pads. Guide horns engage the roads wheels to limit side to side play.
First TTS being fabricated for T005 (friction drive): http://www.rctankcombat.com/order-of-battle/tanks/T005/Page4.html First sprocket driven TTS on T028 (converted from friction to sprocket): http://www.rctankcombat.com/order-of-battle/tanks/T028/ First production TTS T040: http://www.rctankcombat.com/order-of-battle/tanks/T040/Page3.html Current polymer TTS from TriPact: http://www.rctankcombat.com/order-of-battle/tanks/T100/Page2.html There are other TTS implementations, just look through the build threads.
