Both teams have battled their way to this, the
scrapheap final. The Navy have been well represented by the Destroyers
who took wins in Backpack Cars, Wheelie Cars and Jet Cars. Dark horses
Hot Property have surprised everyone by starting with few scrap-skills
and dominating the markets of Ice Racers and Fire Engines. This build,
however, is like nothing else they have faced so far. The teams will be
constructing tanks. On test day, they will have to navigate 3 trials. The
first is to drive onto a mucky/muddy/sandy firing range and take out 3
targets. The second has them racing around the same course to take out
5 targets and get back across the finish line. Finally, it's a head-to-head
shoot-out where they must shoot at targets mounted on the opposing teams
tank. The deadly ammo for this...potatoes!
Hot Property are going with a traditional, and complicated, tank. They want to mount a large truck onto a second chassis with 4 axles underneath of it. A total of 6 axles will be surrounded by tank treads, driven by the wheels of the truck on top. No fancy turret for their spud gun either. They want to concentrate on getting the tank portion built. The concerns facing Hot Property are building a system to keep the treads on the wheels and finding 4 matched axles/tires for the base. While they now have good fabricating experience, can they still overcome the odds again?
The Destroyers are going with the other tank design
of the modern army, a wheeled tank. They will use a four-wheel drive truck
and cover it with metal for protection from flying spuds. This design might
"high centre" (the bottom could get caught on a hill, lifting all drive
tires off the ground) so they want to add a 3rd axle and make a 6 wheel
drive tank. Finding a good 4WD might be somewhat easy but adding that 3rd
axle is daunting to say the least. They are also going to add a turret
but will that just add too much to their already heavy workload?
