yep we are taking ' vertical' or as near to vertical shots as possible which need the aircraft to be sharply banked over for a second or so. and that is what concerns me as there are two methods to do this:
Rapid sideways flight
or fly over the target slightly offset and turn in sharply over it - this works really well for comfort but gives the photographer very little time to react and takes time to set the shot up again.
Clearly an external mount would work better!
