the great thing about the Hyper 7, is that even though it is RTR and rather inexpensive - it is easily a raceable buggy and can get a podium finish with a good driver. Electric STs are harder to drive in my opinion than an 8th scale buggy, so u should have no problem with it. the hyper 8port engine that it comes with is pretty powerful and will be adequate for entry level racing on all but the largest tracks. Alot of people invest in putting on an OS .21RG carburetor as the stock hyper 8port carb seems to be troublesome.

Other than that - good choice, and have fun.
