But Crimson Thunder was MUCH bigger than Nitro ever was.
And Nitro-Gene 4.0 had much of whats in it now, but what Ive done to make sure is its as lightweight as possible, so Ive made it smaller in width and height than any of the previous versions, and so its lighter than before, and there arent massive changes. The shock-proofing is also being used to hold the armour to the chassis as well as shock-proof (an idea used by Kody on his new machine, The Zodiac) and Ive gone back to 6 wheels, and Ive taken off 2kg of Nitrogen, so I now have 4kg on board. The armour is the same, the weapon is improved slightly, and its got 6 wheels, so its in weight.

If its too much trouble I may as well scrap 5.0 and just settle for a 4th version.
