Abstract
A rotary wing aircraft apparatus has arms extending from a body, and a rotor assembly attached to an end of each arm. Each rotor assembly has a rotor blade releasably attached by a lock mechanism. A clockwise rotor blade is releasably attached to a first rotor assembly by engagement in a clockwise lock mechanism, and a counterclockwise rotor blade is releasably attached to a second rotor assembly by engagement in a counterclockwise lock mechanism. The clockwise rotor blade is engageable only with the clockwise lock mechanism and the counterclockwise rotor blade is engageable only with the counterclockwise lock mechanism and cannot be engaged in the clockwise lock mechanism. A leg extends down from each rotor assembly to support the apparatus on the ground.
