+1 on the ae car, partially because I'm Associated by heart, but I had a friend who ordered a Redcat EXP Pro, and after a few laps on the track, noted that the shocks were leaking oil and with no crashes, one of the control arms was broken. Ordered in a few more from the Redcat parts store, and again, in a few runs, boom broken front arm.
I haven't had too much trouble with Associated parts and buggies, except when I let an inexperienced driver behind the radio...
AE FTW!
