I have to come back to this. Been at the back of my mind for a while and a recent posting on BOPL triggered it.
Matt I don't think you or anyone else should be flying a partially guided missile anywhere close to the general public. I can't go to the extreme and say you can not fly at all. However I will say that you need to find some section of Area 51 and fly there. If anyone want's to come and watch then they have signed off on the potential harm that might come their way.
Now don't get me wrong I just may be one of the spectators or if I win the lottery a builder flyer. However I sure will take the maximum precautions.
So this answers your roll rate and signal fading and other problems you have created by competing with air to air and air to ground missiles. For the rest of us poorer modelers spread spectrum would be more than fast enough.
Would also take away the AMA's Reason For Being Number Two -- Save The Frequencies!

900Mhz range. 12 miles line of site. 8mSec signal acquisition time. 38.4 kbps.
As this could be a bi-directional system you could get back engine and flight data in real time.
You are on the right track, but if a 300 mph, 700 degree per scond roll rate is what you are after, you have to take into account fading, antenna patterns, cross polarization and things like that.
That range is achievable only if both antennas are cophased/perfectly aligned. Cross polarization can cause a greater that -20 db gain reduction (in theory, the reduction is infinite)
Getting these things to work in planes is not easy.
