I've only seen two Losi Strikes, the first chassis had snapped in half following a bad landing, the seconded survived a race meeting without any problems (on a small Astro Track). It had CVD's, and a Ball Diff and an EZrun brushless system but other that that it was standard.
The owner of the Strike didn't enjoy racing it so it's on the bay right now (without radio gear though).
You should probably check out
www.rcshortcourse.com it has loads of useful information on all of the trucks available ATM.
