hi from experience with my son, he had just turned 5 when i got his first rc, it was an evader rtr truck, we still talk fondly and laugh about the beating it took and the lessons he learnt. that was 6 yrs ago. looking back a truck was the best choice as they can be driven on grass with the larger wheels as well as gravel pits and parks, bmx tracks, the beach ,camping,the street . you name it. you can not do that with a buggy with the smaller wheels. the evader has moved on.he has been through a b4 , b44,t4 since. we share our cars now, as he is a good driver now and doesnt break anymore. he didnt want to race till he was seven , but it surprised me how welcoming everybody at the track were no one complained about him hacking them they only offered him encouragement. enjoy your son and dont stress when he breaks the can easily be fixed by him.
