    Excellent description of Props and Torque-steer. 👍😁👍

    thank you for all these informative videos. It amazes me how complex these simple machines really are.

    Thanks for this series, Miro! I'm even more glad I chose a Scout, now. Can you do a design segment on reserve parachutes? (i.e. trade-offs of where to mount them, where to mount the pull handle, where to attach the risers, etc.)

    Great episode clearly explained :)
    Q1) - I wonder what you guys think to pod harnesses on a paramotor ?
    Q2) - On most paramotors the prop sits outside of (behind) the cage rather than being fully encompassed by the cage which can allow the lines to get caught up in the prop in the event of a botched launch or landing, why is this the norm ?
    Cheers in advance :)

    Hi Miro, you in your videos gave me the most knowledge about paramotoring, thanks keep it going but I still think the the lighter propeller is better over all. Just because it takes less energy and time to accelerate and less energy to keep it going.

      I might be wrong but i dont think it would take more energy to keep it going, the heavier weight will have a flywheel effect so will have more intertia?

      Your are right about the acceleration but not about the keep it going part.
      Once the prop is spinning at steady speed the only force to slow it down is the drag. This you need to continue to apply power to overcome this drag. Weight is not in the equation.

      @@SCOUTaviation Yes you are right. Newton's law of motion. I was talking about the heavier and bigger, more friction and more drag. Negligible in this case. However, to me the whole purpose of making carbon fiber propeller is to make it lighter, otherwise you can get a wooden prop for half price and get bigger flywheel effect.
