That's why I was conscious of including purpose of recreation/sport in citing the FAA policy restrictions. In fact FAA has cracked down on commercial use of model aircraft, most notably the heli AP enthusiasts that sell their photos to RE agents and such. They have been grounded by current FAA policy, though FAA has said they are considering changes to accommodate them and similar activities under a new class of UA with less stringent a/c and pilot certification standards than the general requirements in the initial UAS policy release.

IANAL, but it seems to me that some commercial activities of an incidental nature are allowed by AMA. Example would be demonstration flights by model manufacturers, employees, and sponsored personalities, which I understand does not exclude them from coverage under the AMA insurance. OP's situation seems similar - I doubt that he contemplates flying at air shows for earning a significant part of his income.

Anybody know if the AMA sanctioned Air Show Teams are allowed to be compensated in any way?
