Boy, you go flying for a day and look at what you've got when you get back!

Dave says if we increase weight we will increase expense. I don't see how that is in any way a correct prediction. Say, with the current 2-meter rule we made the weight limit 4.5Kg. What would happen to costs? Of course they would go much higher. So if we buy into Dave's theory that higher weight would only lead to higher costs, then were damned if we do and damned if we don't. I don't accept that. It is only reasonable to assume that if our 2-meter models could weigh more then they could be less expensive.

As to all the IMAC comparisons, the only legitimate comparison is in the 50cc class of models. You can buy IMAC 50cc ARF airframes for $600. Equip it with pretty much the same radio gear as in a 2-meter pattern model. Then put in a $400 gas engine and you're ready to compete. You have much less money into it then a 2-meter pattern model. It probably weighs 16-17-18 pounds. Now if it had a maximum weight limit of 12 pounds, what do you think it would cost. Of course, much more. To compare a pattern model to a 120" IMAC model is comparing apples to oranges.

And then of course you have the basic inequality of weighing the different power systems in different states of flight worthiness. An unfair situation that in itself is a good reason to change the current rules.
