Not so. The average person can, right now, cough up about 10 to 15 grand for a fully capable, off the shelf system that can fit in a simple medium scale model plane and fly very great distances out of the line of sight with full up and downlink capability. All you need to know is where to look.
They are not all that hard to find, but adding such a system would make it a non AMA-category aircraft - which leads back to my original statement - there are no legitimate security concerns with AMA-category model airplanes...
