From floor to the optimal camera placement is about 2.5ft. But also, what I forgot to say is that I would be filming ground targets. Ruffly 1,500ft off the ground. Sorry for my imperial system of measurement, its considered standard around here :P Thats why In a way, I don't want to be mounted. As far as coupled, it has to be a clip or somthing along those lines. I do not own the plane, as well as most people don't take it kindly when you say your drilling a few holes in there quater-million dollar aircraft.
