Hughes MD530F with 5-Blade Head (HU53 military version)

Maiden flight of 450 size MD530 with a 5 blade main rotor, trying to achieve the lowest head speed possible and maintain rock solid tail! I've spent almost ten years developing this electronics and gear ratio setup. Shhhh.... don't ask...it's Proprietary info. LOL
NO sound editing, this helicopter has a very unique (almost turbine like) sound.
