  1. Electric paramotors might save us from torque by using an even number of propellers (2, 4, 6, etc) spinning in opposite directions. I say electric because this would be easier on them versus using two propellers on a combustion engine. With battery advancements e-Paramotors are the future and torqu is one of the reasons, IMO

  2. I understand weight is a big factor in paramotoring but could you use a gearbox that used two counter-rotating props ? I would think you would get an advantage from thrust out of two props but there might be a weight disadvantage as well.. great videos I'm watching them over and over again picking up little tidbits of information. it really seems like you have worked out all the fine details and trying to make the best all-around paramotor. you have me sold I'm waiting on financing as we speak… thank you for the videos and I always look forward to more videos and information

  3. Awesome series.  I immediately agreed with the belt vs gear reduction systems being no different but I had a thought that if the engine pulley had a bit more mass to it wouldn't that counteract at least some of the torque?  I know weight is our enemy so it's just a thought. Keep the videos coming!

  4. Definitions of aeronautics:
    A Propeller's direction of rotation is classified while viewing the propeller with the engine placed behind the propeller. A Paramotor is viewed from the back, a Airplane is viewed from the front, and a Helicopter is viewed from above.

    Turns to the Left = Counter Clockwise Rotation = Left Handed turn
    Turns to the Right = Clockwise Rotation = Right handed turn
    (Think of the steering wheel of a car and the car's resulting direction)

    The Aeronautical standard is the propeller "Turns to the Left" and the engines are configured accordingly.

  5. Great videos
    Thanks.

    I really like the scout paramotor except for one detail, why is the prop behind the cage?
    Most new paramotors are this way.
    I have had the lines tangle up in the prop several times during ground handling mistakes and it was a big mess, splintered prop, crushed cage, broken lines and some times it pulls the lines out of the wing.

  6. if the weight of a counter-rotating prop and gearbox would be an issue maybe use something like the counter-rotating props on a quad or a trike where weight isn't as big as issue. that way you can take advantage of 2 props and maybe get more speed or better climb rate. I realize this is thinking outside the box. most of your paramotors are engineered extremely well but this would be something to consider

  7. Hi, first of all nice videos! what about if you are light and you fly a big paramotor? can you "compensate" the torque by simply reduce power? example if you are 60 Kgs and you fly a 200cc… or its not advisable at all? (during take off)
    Thanks!

  8. if a 3 blade prop is more efficient than 2 blades,, why don't we see it more often? wouldn't it just make more sense? saving fuel and all? another tangent question,, why didn't you design the carbon shroud a bit wider so the props can benefit from the ducted design?

  9. I wonder if torque could be canceled by employing counter rotating propellers ? You think ?  I wonder why it hasn't been done yet ?

  10. Are there any contra rotation gearboxes made for paramotors?
    Have you tried one?
    Great channel you have made!
    Cheers from Finland.
