Sure, if you're an AMA member -- you could wait and hope for change. If you're not an AMA member, then I'm not sure how it'll benefit you.
This pretty much nails it!
It's hard to dispute the overall need for a registry like this, but the Special Rule for Model Aircraft in the 2012 law explicitly has a carve out for members of organizations like the AMA where they are already registered and operate under strict safety guidelines.
I was surprised that the FAA hasn't really over-reached with this registration program (though it's far from perfect), other than ignoring the clear instructions Congress gave them in the 2012 law in regards to model aircraft and organizations like the AMA.
But that over-reach is STILL an over-reach and as a people we should never tolerate this from our government institutions! This registration program can still be effective without the FAA exceeding their authority, there is no practical reason for the FAA to over-reach like this, none what so ever!
You have a choice to join the AMA and be under the blanket protections that Congress carved out for such organizations, or you can register with the FAA as an unaffiliated RC pilot (or do both). Or ignore the whole situation and hope you never get caught. Or never fly again after December 21st, 2015.
It's entirely your choice.
I became an AMA member long before this issue of registration came up because I enjoy the benefits it confers on me. I'm happy that Congress saw the value of community based organizations like the AMA and am saddened by the FAA's myopic rush to ignore that very same value in a fit of blustering bureaucratic over-reach with a claim of "good intentions". The road to hell is paved with good intentions...
