Dave,

It's not the majority of airframes, it's all of them. Please tell me one model manufactured just for AMA pattern?

There simply will be no need for higher power systems in an event that will be flying F3A developed airframes. Particularly with the less demanding patterns that are in AMA. I can keep repeating that if you wish.

Right now we don't push the limits on wingspan, because it is not necessary. The same will be true for power to fly AMA with an F3A airframe.
