Okay, so I drew up this idea to make a (rough) TTT out of two bits and some misc. items.
I would hack the two bits in two. One section with the steering mechanism and two sections with the motor and gears. I would then make a bushing and center it on all three sections. A metal rod goes through the center. Now, the three sections can articulate 360 degree's. See where I'm going with this? A tube chassis could be made to go on top to limit the articulation. Sure the TTT would only be 6X4, but it is a (rough) TTT right?
Well, the bit's don't use a rx/ESC combo like the "real" TTT trucks do. They use a binary pcb to do all the work. When I get around to building this, I'm working on another project at the moment, I will mosfet the board to allow more amperage to the motors.
