Still not something to likely be enforceable unless the FAA starts posting up at model airplane fields (they won't) or someone does something dumb and puts it on YouTube (they will), or worse comes close to a full scale and gets reported (pretty unheard of outside of quads/drones, which usually aren't originating from a model airplane field).
Remember the FAA spells our transponder, meaning your aircraft will have its own ID registered to you in the airspace and they will know when you brake the 400 limit. They will start with a letter and fine I'm sure. Sucks
