4 more elements
A rotary wing vehicle comprising:
- a vehicle body;
- a thrust vectoring mechanism rotatably mounted to the vehicle body;
- first and second contra-rotating fixed pitch propellers mounted to the thrust vectoring mechanism:
- a coaxial propeller motor assembly connected to the first and second contra rotating fixed pitch propellers;
