Tamiya Konghead Project

Now here's something you don't see every day.  Scale trucks with multiple axles are not that uncommon in RC, but this is not exactly a scale truck.  The 6x6 monster truck G6-01 chassis was new for 2017 and this is the first model to use it.  It uses independent suspension on all 6 driven wheels with friction dampers on all corners.  Both the front and rear axles are steered.  Although the 6 wheeled chassis is new, it is based on the slightly older GF-01 chassis and simply adds an extra axle.  The suspension uses the control arms from the CC-01.  The frame is a continuous gearbox of spur gears which connect all three axles to the input pinion.  Every axle has a differential, all open.

This is not a high technology vehicle.  I suppose it is a bit of a gimmick, but it is successful in this regard.  Even with the single brushed motor and the lack of oil filled shocks, this thing is super fun to drive.  It is pretty quick and can even jump.  The rear wheel steering is not strictly necessary since the turning radius is very good without it, but add the rear steering and you can do doughnuts all day long.  Suspension travel is adequate for light off road use in gravel or grass, and with so many driven wheels it rarely gets stuck or high centered.  The body, despite being a bit odd, is pretty good looking.  The name is derivative of the 58089 Bullhead which also uses a tractor truck body on a monster truck chassis, albeit with 4 wheels.  However, where the Bullhead uses the huge Clod Buster tires, this model uses much smaller tires and ends up only the size of a standard 1/10th scale model.  Of course various fans have already made 6 wheeled Bullheads to look like huge Kongheads.

One nice thing about the newest generation of Tamiya chassis is that the battery compartment is finally square and a bit oversized so standard Li-Po batteries can be used.  I used a pair of high torque analog Futaba servos for four wheel steering, and kept the stock ESC.   I find it to be quite capable out of the box as long as you use it for what it is.   It is designed for fun, and it is optimized for it.

Update:  This model was destroyed in the 2022 fire.  It has not been replaced.
