((((KYOSHO)))) all the way if you've got the cash(which you have) try the mp7.5ve brushless(115KM/H out the box) or if you like to tinker and mod engines then try the MP7.5 MK3 with the GX21 engine, the engine can easally be tuned to become a racer(which it already is but can go alot faster). Seems how your old school you'll probably already know that Kyosho is world champion, and still is. Money wiselly spent is money spent on Kyosho,[8D] but then again if you just want to hand with the pack buy something from Losi or Mugan but what ever you do go for 1/8 scale. There tough as nails and really fast.
For the rest just have fun with whatever you get.
You could also just read all the info here on rcuniverse and get the first hand xperience from the different people here on RCU.
