I partially agree, however, I don't think special equipment or radio limitations is the way to go. Personally, I would rather see a class with either an engine limitation, or plane size, the last one would probably be the best.

We have 3 classes here in norway, one beginner class, where people fly what they have. We also have the standard F3A (top) class, where everyone use the best equipment. The 'problem' lies in the middle class, where people mostly use 2meters. The schedule isn't really that hard, flying it with some 90 size models would enable more pilots to fly, and decrease the need for expensive planes.

As competition in the lower classes here isn't really at the same fierce level as in other countries (ie. US), changes like these would make different results in the different countries. In places where the competition is hard, some would probably make high-tech components which obey the new standards.
