We just switched my oldest boy from a built apex 90 to the 250 raptor, he has been racing since he was 4 and is now 13, he did race a 125 raptor last year when he blew up his apex, just waiting to see how well he does in the school boy jr class this year. My youngest boy is running the apex till I can find a 125 raptor for him I am tire up those money pit mini's
