THe first thing you will want to buy for your buggy is a new clutch spring. The one that comes stock will break very easy. Here is a link to the part.[link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXUR89&P=7]CLUTCH SPRING[/link] This spring is very good it will not break for awhile. Another good one is a 4146x that is a traxxas spring that will fit right in. The only thing is you can not use the clutch shoes that come with it they are to small. Here is a link for that spring [link=http://www2.towerhobbies.com/cgi-bin/wti0095p?FVSEARCH=4146x&FVPROFIL=++&search3=Go]4146X TRAXXAS CLUTCH SPRING[/link] Again good luck. later Greg
