HitecMan,
In the St. Louis are 4*'s are pylon raced by several clubs - either the stock kit or ARF w/o wheel pants and a ST G-40. We race them since they fly great, you don't have to spend a fortune to compete, and since everything is on equal footing - it's all up to piloting skills.
Here's our club site:
