Hello to all....We have a problem with a Tornado XP (two speed) that my son got for a Christmas gift. It has been run maybe all of two hours combined. One day when he went to use it, it started out at high rpms and was going all by itself. He tried to adjust the needle valve to lower the rpms but then the motor would die and the wheels would still be moving. He took it in to a hobby store and they tried to adjust it also but they couldn't get it to work either. It still is at way high rpms and lowering that just causes it to die with the wheels still spinning. Any ideas?? Thanks in advance for any and all help or ideas anyone has. This is his first gas vehicle and he is extremely frustrated that it only worked for a little while and being beginners we don't have a clue what to do now.
its the clutch spring, replace it with the traxxas 4146x spring, also i would suggest upgrading the clutch bell also
