I can think of quite a few nose mounts that avoid the lower cutter
Whilst the single pole brackets can be fitted the cutter can get into shot and is compromised because the camera sits well in front of it.
Incorporating a cutter into nose mount hard point (the so called sharks fin on AS 350 single pole mounts) would be a help, because the area between camera pole and nose of the chopper is a natural trap for wires that slide down the windscreen.
Any stats on the number of occurrences, without wire strike kit of where the wire bites, is it mast or skids/crosstubes?
