Tony,
Thanks for the opinions on the rule changes. Various proposals over the years have been advocated for more than 1 reason, reasonable enough.
When 120 4Cs were allowed into the event, more power was available, it was used, and costs went up (and the event did not get quieter, the noise rule did that).
When unlimited sized engines were allowed into the event, more power was available, it was used, and costs went up.
Make a rule change (such as allowing increased weight, or unlimited weight) that allows more power to be available, and it will be used, and costs will go up. As I've pointed out before, the equipment needed is already available, it does not need to be developed by AMA or FAI flyers, it already exists, and it costs more $$$. The only prediction is that it will be used, and history says it will be used. Competitive nature says it will be used. History can't be changed, and I don't see competitve nature changing either.
Regards,
Dave

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.
