So the photo above is Kinwalds SC10 4x4 at the Short Course Showdown. Notice the following:

1) Dual Shorty packs
2) Revised servo mount using B4 brackets
3) carbon fiber frame for stiffening.
4) No middle belt tunnel
5) Motor fan
6) a bunch of weight forward

I am planning to mod my Sc10 4x4 nearly as much but in a different way. I plan to push this chassis as close to 50/50 weight balance as possible while keeping the overall weight as low as possible. Mind you that I am starting with a stock kit with NovaK Ballistic 550 4.5t motor. I plan to install a fan and run tall gears on the motor.[/QUOTE]

Hope to see some pics soon
