Dave,

The increase to 20cc for 4-strokes was never sold as a cost reduction. It was for noise. There were some who claimed that there might be a cost reduction when F3A removed the engine displacement limit. I never bought it and I don't think it passed for that reason. The 2-meter limit was imposed to help limit the cost of shipping the models to World Champs. Some models were exceeding that when it was put in place. It probably has done that.

Escalation simply wouldn't happen in the AMA classes. If I follow your logic then there is absolutely nothing that can be done to help the event. And I don't buy that.

I believe you are wrong. You don't get it. So be it. Enough said.
