The goal is to attract the larger, more complex and more impressive aircraft and their owners to the event. I have seen the development of the foam warbirds and they are getting more impressive every year.
Horizon markets their 80, plus inch T-28. I would not exclude that plane from flying as it is large and impressive.
I suspect one of the unspoken issues is the level of commitment. Someone who has a couple of thousand hours in scratch-building a warbird might be concerned about the relative flying skills of someone flying a plug-and-fly model. The risk of collision and loss from the actions of an inexperienced pilot is a real concern.
As I said earlier, I will allow the entry of the planes based upon wingspan but will discuss the issue with everyone at the pilots meeting. Perhaps we will have a timeslot for the injection molded planes. I'll keep an open mind on the issue and see how it goes.
