If I remember correctly the original reason for the weight rule was to keep some of the TOC airplanes out. At the time the weight rule when into effect the TOC and IMAC airplanes were not as big as they turned out to be now. I remember at the time Dean Pappas had an Laser that weighted 18 lbs and would fit in the box with the short spinner. At the time the pattern flyers didn't want to deal with those airplanes.

That was 20 or so years ago. The difference in these airplanes has gotten so wide that I don't see it as a problem anymore. Heck when I started flying pattern you were not allowed an engne bigger that a 60. Then the 4 stroke people got it changed to 60 2 stroke and 120 4 stroke. That rule was dropped when it stopped being an issue. The difference between a pattern airplane and an IMAC airplane is now so large that you do not need the weight rule. Keep the size and lose the weight. At least in say the lower couple classes.

They use to allow a bigger airplane in sportsman to try to bring in new blood. I didn't do it because I hate the sportsman pattern. I want to fly advanced. I know this would help me restart.
