The team would like to use a three wheeled vehicle for ease of steering setup (two fixed spindles and one steering spindle). The question became 'steering spindle' in the front of the vehicle or the back?' Considering that the prop has been placed in the rear, it seems safety again drives the location of the two fixed spindles.
With the mass and height of the prop creating a rather high CG at the aft end of the craft, it's determined that the two wheels should be at the rear and have a rather wide track for the sake of stability. A solid (but breakable) axle will connect the two rear wheels and be used to drive the prop.
