the slash and new emaxx have exactly the same wheelbase.
widen the slash with the rear arms all around or the jato wide arm conversion, add half offset truggy wheels and the width might also be similar.
punt an emaxx body on and you have a lightweight 2wd emaxx....
hey, my stampede dosent tip over. and thats doing 30mph power slides on-road with moabs . 12.5" wb, 13"with, 1 3/8 gc...... actually i was thinking about doing the same thing. although more of a buggy.
Do you have a stock chassis to use? Would be much lighter tht way. You could take out the diff and tranny and put an outrunner where the diff would be. I bet you could get the truck under 6lb rtr with that setup on 4s.
You could try something like this: http://www.hobbycity.com/hobbycity/s...less_Outrunner
Maybe have mtxmugen rewind it to ~180kv.
