I'm gonna do the same thing... Gonna buy more recievers for the other rc's i have / am going to get... It is kinda annoying to have 5 different radios to carry around for 5 cars... (even though i only have 2)... I was the first of all my friends to upgrade from the stock radio to an FM... All i can say it, wow, what a difference! No more glitching or anything! And synthesized is awesome, even though none of my friends have FM radios, but if i ever go race, i just turn the knob and push some buttons, and my channel is changed! Awesome!
