Following the arguments of those above, there is no reason to believe that a .60-size plane will be any more competitive against a 50cc plane than the 50cc plane is assumed to be against a 150cc plane.

Also, the .60 plane is significantly cheaper than the 50cc plane, so I fail to undertand how creating a class to be populated by larger more expensive planes will help those who do not want larger more expensive planes.

The simple fact is that this is competition and most people simply do not like to compete. For instance, less than 10% of AMA members enter any kind of sanctioned contest in any given year. Not a year goes by that someone does not raise this issue. Let's limit the size of planes to get more people to compete. Yet, a size limited class exists and nobody flies it. Why not??
