Since the FAA is trying to regulate the sUAS's then it seems that they should make a definitive statement about what is and isn't an sUAS. I have a simple definition that might help. If it has any capability of gathering information external to the aircraft (cameras, sensors etc) for live transmission or post flight downloading then it is an sUAS. Anything else is a model. Yes, models carry cameras today. I would say that if they do so then they must comply with sUAS rules. Leave the pure model aviators alone.

I guess this is too logical and simple.
