A little update
 

Made a few changes a while back,put it on a diet,the first build actually weighed around 14lbs.It's lost 990 grams,now comes in at under 12lbs RTR including body.
Also lowered the rear pack by making a new rear bulkhead brace,strengthened the chassis too by attatching it in more places and bolting through the 3 decks front and back.
Got this system running nicely now with the MGM,I run it on 7s now instead of 8,and got the gearing sussed.

I've been working on a much lighter build too,with hellfire shocks,centre diff(and f/r truggy diffs),smaller system and lighter chassis etc it works out at 4.3 kg.Building a maxx at the moment aswell.

Nice Gustav! nice shocks as well.

very sexy setup, get steven spielberg over and shoot a movie for your fellow RC addicts..
