Also included in this version of the bill is a prohibition on "home brew sUAV's," which could effectively end what is a major part of the hobby for many of us: building. With that, and the possible design certification requirement, it seems there exists a possibility that all current r/c aircraft, including ARF's could become illegal since none of them are certified.
