My opinion the 501x.
Iv owned a few 4wd cars, inc a yokomo, lazer zx5, bosscat, procat,egress,avante,trf501x, lazer zxr, optima mid to name a few over the years.
The car that i have broken least is the 501, The only things broken include the front shcok tower and shock shafts either bent or snapped. Not bad considering 4.5 sintered power and a slightly throttle mad thumb.
Col.
