I found it to be less durable than a revo with RPM arms/carriers, a new era rollbar and rear wing.
Axle carriers for the front, arms and chassis rails tend to break with heavy bashing. The two speed doesn't care for high power engines or the big ass tires that it comes with. They tend to strain things a bit.
I had an aftershock, but had 2 or 3 friends with LST2's. We all bashed in the same places and broke similar parts. After quite a few upgrades and some manufactured parts, mine was a tank. But all of us found much fewer issues when we dropped the tires down in size. I ran revo tires with 17mm hubs on mine. My friends both ran muggy wheels/tires on theirs.
The most frustrating parts for me were the chassis rails. I broke 4 or 5 sets of those in a season. They are not pleasant to change.
Then over the winter, I made a skid plate that tied the front to the center, then ran it for 2 years without issues regarding the rails. I also upgraded to RPM arms with lunsford turnbuckles in the upper arms, lunsford turnbuckles all around, RC Raven dual rate springs, a homade roll bar to keep the body from crushing on band landings and thick rubber grommets between the front/rear skids and the bulkhead brace to keep from busting the stupid skid support. I also upgraded the brakes (stock aftershock steel disks were horrible) and bought alloy diff carriers.
After all that, mine could pretty much take on a brick wall.
