Say you own "Great BIG RC Hobbies" and attend an event and also have a vendor booth at the event, does that make any flying at the event "business purpose"?
before we get into that guy,
lets talk about his brotherinlaw:
He owns SuperRCHeli.com, and also has a vendorbooth for his business at the event.
But THIS guy takes a break from his commercial booth to enjoy some hobby flying of a 3d Foamy Bipe.
I dont see that guy as commercial flying, because the bipe flying is unrelated to his commercial booth.
Now back to MrGreatbig, of GreatBig RC Hobbies-
If Mr Greatbig takes a break from his booth to fly unrelated to his business (maybe a fun Balloonpop round )
I dont see that as commercial flying.
But if MrGGreatbig puts on a sales demo flight
of a product as an effort to sell more of that product,
that sure sounds like a business activity more than it does hobby.
Heres an idea for a metric:
If you catch even a little bit of flack from some 'boss' type business person
for just skipping an event you were ordered/directed/required to attend for stuff you get/got,
then that aint recreational hobby flying
