Top tips...
1) seal the carbon fibre chassis and shock tower edges...i put a thread about sealing carbon fibre in the general car chat topic. there are some tips in there..
2) if your running lipos, get some lead around the lipos. A nice neat way is using a rudebits brass or stainless lipo retainer tray...or just slap some stick on lead between the lipo cells.
3) build the diffs almost as per instructions...just clean all parts using brake cleaner, white spirit or a degreaser of some sort. You can lightly sand the diff rings with some very fine 500 grit wet and dry to help them not slip as much
4) green slime the shock seals during the build.
5) try my starting setup in the setups section on arn0s link in the team associated section. If you cant find this, i can help you out
6) tap out the threads in any plastic parts using a 4-40 tap and tap handle. This will reduce the chances of stripping threads in plastic.
Hope this helps.
