I have flown 1 IMAC contest in the SW region. I flew my 60-90 Edge. I had the smallest plane on the flight line but I finished above some of the guys flying 50CC size airplanes. Two of the guys in basic were flying 100 CC sized airplanes. A young man 14 or 15 years old, flying a 1.20 size Giles finished I believe in second place. It is possible to fly a small airplane and be competitive. Remember it's not the size that matters, it's how you stir the sticks....
