Yo Crashalot, I have had my MP7.5 now for a couple of years and I can tell you its a blast even now against the newer generation of race bred buggies. The oposition still looks up at it to find insperation so if I was you just go to your local hobby store and get yourself the Kyosho.
You can find all the info you'll ever need for it on our forum here on Rcu, KYOSHO Inferno U.S sports, got check it out, there is alot to read about how to tune it up some aswell.
By the way, welcome back.
