The problem isnt the weight itself, its controlling it. This is where the big bore shocks come into their own. My Losi is now as good as, if not better than the durango on astro, at kit weight. The only place the losi looses out is on initial max acceleration, and that could be differences in power bands of motor/speedo/gearing etc. Through the corners the big bore conversion puts the losi right up there.
