    Thanks for doing these videos. I'm converting from fixed wing to rotary so good to understand the aerodynamic differences.

    Thank you for the video
    May I know why we have tail rotor tendency ? The video tells me there is tail rotor tendency but did not explain in detail why this happen
    Also why moving the tail rotor up to level to the main rotor will reduce this tendency ?
    Thank you very much ❤

    Very useful. ..Thanks

    Do contra-rotating rotors with no tail rotors produce no drift then? Such as in the Russian Ka helicopters? Also is this a Dutch accent?

      Yes, and you can even Yaw by just rising the COL of one of the rotors

    The vertical thrust vector shown in the diagram is the wrong way. Should be downwards for lift. Needs to be correctec

      Lift pushing you down sounds like a very bad time. I think you'll want to keep it the way it's represented.

      @@flightfirst6311 The diagram has "thrust" not "lift" though. The diagram has the thrust pushing you down. See ua-cam.com/video/17_FzAuoeWw/v-deo.html -- the diagram works well if you change the word "main rotor thrust" to "main rotor lift"

      @@glennwatson When the rotor thrusts of all the blade sections are combined, total rotor thrust (depicted as main rotor thrust) acting through the top of the mast provides the force that overcomes the weight of the helicopter. Both the tail rotor and main rotor provides thrust.

      @@flightfirst6311 been doing some googling. If you see this diagram api.intechopen.com/media/chapter/57483/media/F5.png we are talking about Vt while they express thrust also as a alternative word for lift.
