Mike,
Probably the most aggressive funfly kit available is The Minus, by TPP(Turner Performance Products). The Menace is a close second, even more appropriate for the "sunday sport flier". The Minus was designed strictly for competition. The Minus can be built as either a Funfly or Unlimited airframe, in fact, both versions swept the funfly NATS this last summer. So, either way you build it, you know it will be good. If you want more info on either the Menace or the Minus, drop me a line...good to see some interest!!
