I'm a commercial pilot, decided to get my 107 last December after the instructor who gave me my flight review told me how he got his. Took the on line test during a snow day and had my temporary that week (I went to a FSDO office to get my temporary certificate issued). 10 months, 6 drones and many hours later I have no regrets about getting involved with new field as after 40 years in aviation I was getting burnt out. Flying sUAVs and actually getting paid a little to do so has been fun and rewarding!
