My CRT.5 has been done for over a year. Been making small little changes here and there. Just fitted a desert rat body on it. Waiting on my new RPM 2.2 truck wheels and some tires.
If you really want to beef it up..try putting 1/8 buggy shocks on the rear and revo shocks on the front. I have done 2 of these conversions and it made a world of difference. Although I was using a longer chassis set up w/ Gladiatior 2.2 tires
