ok - heres whats on my desk at the mo, just about got it all back together - why do some parts have to hide from u...?
I like a clean look
erm... ah, well, mine aint the best to get clean looking ideas from... but here u go - u can just make out the bracing points that im going to use on the seat and servo plate. (just to keep it on topic

)
craig - im not keen on bracing between the towers, theres too much leverage on the towers that can bend them quite easily for my liking. with some more supports from the chassis it may be better tho - try it, see what happens man.
