Okay I got some more driving time at the track and the jumping is much improved. I did however have that same screw on the caster block fall out again but otherwise it held up well. Since I'm a pretty terrible driver, I do land jumps wrong and crash sometimes, I think I'm a pretty fair judge of durability. I'm pretty pleased with the truck so far. I prefer driving this over my Slash 4x4 most of the time.
