Thanks.
I generally maintain about 500~600' AGL and monitor the digi output through a digi camcorder LCD. I literally hang from the heli though, so it's a bit unnerving. I charge around $300~350 USD per shot for aerials, depending on quantity, and $400/hr. helicopter time. I developed the technique in 1999, and to my kowledge was the first to produce full-spherical aerials... can't confirm though. But it's sure been fun doing them! I'm currently building my own chopper from scratch, su hopefully next year we can pocket that $400/hr heli rental and let the aircraft pay for itself.
Cheers,
Brian Jackson
