Sounds like you have problems with you clutch engaging too early. You will have to take apart the clutch assembly and make sure everything is in working order. You might as well replace the original clutch and clutch bell with a new [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLW03&P=7]HPI racing clutch [/link] and [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLST6&P=7]clutch bell [/link] while you have it apart. You will also need to buy bearings for the new clutch bell, I am not sure what size bearings are needed sorry. The stock equipment is not the best and has durability issues.
