I have it ( and a bunch of other bodies) and on a 1-10...9.5. It's fun, has smooth steering and is very fast. The motor can be "hopped up" to a Kysho X-Speed motor or others(though you should be careful, other companies motors are too fast for the stock speed controlers and an external speed controler, or turbo, needs to be installed) Appearance and detail are awsome, though the bodie is not flexable like lexan. It will break and crack if wreaked too much(usually the first thing to break off are the side mirrors). The car is not 1/24 scale, it's actually 1/28. It's not noticable until you put a model car of the body you are running next to it. Suggested hop ups would be the mono-shock, bearings(not duratrax, they are too thick), X-Speed Motor and rechargable AAA batteries for the car(cheaper in the long run).
