    It does appear that the tail rotor rotates the wrong direction. The rising blade should be rising into the closest downwash of the main rotor. gets higher wind velocity across the blade and there fore more available thrust.

    chin bubbles = extra forward visibility during nose high attitudes -

    and that chute will cause more problems then it's worth. Seen lots of failures you're not the first to try.

    A helicopter is not a gyro.

    I dont know what you would do but descend inverted if you deployed a chute. Cant go up or the blades will cut the lines. If you lost a blade, you would be killed instantly, so thats not a reason to have one. Autorotations are not that big a deal. Chin bubbles or windows by your feet are hard to not have in a helicopter.
