If you are going in a series motor you will need big wheels and tyres, we did it in the SIIa but cos we had the little wheels on we kept grounding out......... even had to be winched down one hill cos it just wouldnt drive
Didnt mean nowt by it Grunt, was just giving the numbers cos you said you didnt know, and the maze can be escaped just before you get to the three routes or you can skip the whole thing but it misses out a really big chunk if you do that
