I just purchased a Smartech Tiger II. Believe it or not I went into this knowing that I would have to upgrade the servos and that if improperly tuned dealing with burned out clutches. Within the first 3 hours I burned the clutch completely which locked the drive train up. As I expected to do as I learned and worked out any bugs in the car and my knowledge. Now the thing runs like a scalded ape. Parts are cheap and easy to get. A new clutch cost $2.00. I save at least $200.00 by buying this car instead of dealing with local dealers. The best website I have found for parts is "www.raidentech.com" in California. I have also found that if you take it to your local hobby shop they will be able to cross reference some part just by measuring them against other brands
