Ok I plan to race, dont really have a budget, I want to get the rc18b. As for electronics I will be getting the spektrum micro sr3500, esc - dynamite tazer, motor - dynamite c4 brushless, battery - maxamps 1550HV 3S 11.1V pack. what servo do you recomend? are the choices i have made some far good? what hop-ups will i need and what are the weak points on this little beast?
