Question: Did FAA dissolve what used to be Section 336 (the modeller guys) and now put them under part 107 along with the drones/quads?
The previous recreational exemption - the "Special Rule" was created by “Public Law 112-95, Section 336”, in the FAA Modernization and Reform Act of 2012, and codified in 14 CFR Part 101subpart E.
With the FAA Reauthorization Act of 2018 (Section 349) It has been superseded by the "Exception for limited recreational operations of unmanned aircraft" 49 U.S.C. Section 44809. 14 CFR Part 101 will be rewritten to reflect that, but it has not yet happened.
