But if we raise the weight limit we will all need to have 2-meter wingspan 50cc alcohol burning biplanes to be competitive. Won't we?? [&:]

Either that or monoplanes will have a fuse that is 2 meters tall. The new names will be 2 by 2 by 2. On the bright side since the wing and fuse will essentially be the same, knife mixing will be a thing of the past!! I can finally fly a scale Star Wars X-Wing fighter in pattern. With a 50cc alcohol motor of course. How cool is that?
