I have an old school Nitro Rustler, as you can see in my Signature.
I really think that it's an awesome truck if you want to run around your backyard or hit some bike jumps, but I honestly don't think it's a contender in racing. IMHO it handles terrible on a racetrack compared to say an RC10GT or XXXNT. I personally am thinking about ditching the Nitro Rustler and buying myself a nice XXXNT Setup. The Nitro Rustler actually doesn't have very much adjustability. For example, there's only one shock position on the front shock tower, and two on the rear. Some other things that I don't really like are that they only have philips head screws, and the electronics are a PAIN to work with. There's also A LOT of unneeded weight.
On the other hand, it's a VERY tough truck and has held up to all the abuse I've thrown at it: MX Tracks, BMX Jumps, Sand Tracks, Street driving, backflips, etc, etc, etc.
