I have a Kyosho MP7.5 4x4 buggy. Yes it hauls, maybe 50-55 MPH depending on gearing. They are a riot, but not cheap. Check out Towerhobbies.com for the best prices. My setup is probably $1,200 or so but Ebay has some good deals on used setups. The buggies are a far more serious and capable vehicle than the monster trucks, but to each their own. The buggies can easily leap 35-60 feet and land easily. The trucks flip alot. You can adjust attitude mid flight with the brakes and throttle too
Very fun.
Forgot to say that buggies are 1/8th scale, and is the most expensive and serious class. 1/10 scale is very common and Associated makes some nice stadium trucks in this size, which are considerably cheaper and of high quality.
