Bigger wheels 600+mm dia (the old ones were500mm) this means I should be able to climb out of the pit at both the RR and RL arena.
Plus the final drive chain is 1/2 pitch instead of 3/8 this wont break as often.
Also the armour has a coating of 8mm three ply rubber belting for the Tupperware Tomahawk (Thz).
I dont know if it will work but I will give it a go.
