It can be fustrating, i have been in the hobby for years and understand 100%. I have had pretty good luck so far with the redcat vehicles. i have the volcano and tornado, the only problem i seem to have is the shifting of the tornado. i will try to adjust tomorrow. Also the engines are a little difficult to tune. i would suggest to get a fuel filter for it since i did see some plastic shavings in the tank before i put fuel in it. but it is an expensive hobby no matter how much $ you spend on the vehicle. Part of the hobby is fixing it yourself. Either ask on the forum, local hobby store etc, if you just pay to fix it you wont know how to fix it next time.
