I will definitely agree with brandon a! these cars are tough!We have been running ours for 2 years now.They have broken, but just about every break was well deserved.You know things like getting t-boned by an E-1/8 buggy, or doing silly things like trying to clear big jumps you know you may not make.I ran AE cars for 20yrs before switching to Academy rides, and after running them for a couple seasons dont regret the switch at all. As a matter of fact I dont think I would trade my gv2 for 5 b4's!!Well maybe , just so I could sell the B4's and get a few more Academy rides!LOL.
