Most people use 2.4ghz systems now which dont use crystasl and are much less prone to interferance.
As for motors and batterys brushless motors that nerly everyone uses are faster and require almost zero maintance. (NO brush replacement and comm scimming) But do require a brushless speedo. and lipo batterys are the way to go but again need a special lipo charger. Just come along to the track and ask questions We are a frendly lot and will tell you everything you want to now.
