All R/C cars have their limits. Run it into a solid object at high enough speed, and every single one of them will break. Likewise, each car has it's strong points and weaknesses. I don't think anyone can complain about how tough the 8IGHT series of cars are in a crash, and Losi has been working on fixing other things (like that dreaded "servo problem"
). I firmly believe that the Losi buggy is one of the most durable out-of-the-box cars you can buy.
If you don't believe me, watch me on a practice day...haha.
Nitro tuning and maintenance is just like anything else; with a little practice, it becomes second nature and no big deal. There is plenty of help to be found, both at your local track and on the internet. Like I said...you can fire any question you have at me and I'll do my best to get back to you as quickly as possible.
