Well, based on what you did, I say you chose wisely. Smartech is horrible in its production standards. Smartech uses inferior materials (poor metals, poorly casted plastics), and the poduction tolerances are absolutely too large. This tanslats into parts that fit okay when first assembled, but as the vehicle takes on heat and expands accordingly, the expansion rates of the parts become mismatched.

Smartech is cheap for this major reason: They seriously sacrifice quality. Some argue that the cheapness of Smartech is a good to introduce people to RCs. I personally say that the poor quality turns off most from RCs. RCs already require alot of involvement: tuning the engines, dialing in the set-up for better traction, replacing parts, rebuilding engine and motors, recutting cooms, and so forth. Why make it all worse with terrible quality? Why force the end user to replace parts more often when the parts should have lasted several more gallons of running? The hobby is daunting enough. I say dont make it any worse with poor quality.
