    Excellent- I have an RC prop balancer using the same principal, but much to light to handle a 130 cm prop. I would be interested to know what you would charge to provide the shaft as shown and the magnets. I'm sure a local machine shop could duplicate, but you already have worked out the details.

    I balance my lawnmower blade the same way. But i have removed the friction and just balance them on a knife edge. I just put a knife with the handle in a vice and let the sharp side be horisontal and directed up. Then i can just put on my lawn mover blade or boat propeller there and check what way they turn. Alot less work but same result i think. As in a round hole the edge will center it selfe by the help of gravity ☺️

  • @JohnnyFaber
    @JohnnyFaber 2 ปีที่แล้ว

    Do you also weigh your prop bolts to ensure they aren't introducing vibrations? I'd think if your using washers to balance only the prop you would also want to include the other components of that rotating assembly in the balancing procedure to ensure perfect balance.

    • @rickardjonsson4526
      @rickardjonsson4526  2 ปีที่แล้ว +3

      No but i assume they are all the same weight and that any difference would be to small to detect on my scale and for sure wouldnt cause noticeble vibration since they are so close to the center.
      I hardly feel any vibrations now, the top80 seems to be a very good balanced engine.

  • @MarkoGarcia
    @MarkoGarcia 2 ปีที่แล้ว

    I am quite curious...do you use those magnets with their polarity going in the same direction on the axis? Is one's polarity inverted from the other? Have you done any experimentation to see if it even makes a difference?...perhaps balancing prop then changing the magnets' orientation to see if the result is different?

    • @rickardjonsson4526
      @rickardjonsson4526  2 ปีที่แล้ว +4

      Glad you asked, i should have covered this in the video. I built it over a year ago and had forgotten about this dilemma untill now when you asked. I thought about it in the beginning, even asked the magnet dealer about it. They said it shouldnt matter how you install them. I still tried different ways and if theres a difference its minimal but to me it looks like i get the best sensitivity when the magnets are facing eachother with the same polarity, to be clear they repell if i put them together. The balance of the shaft remains the same.

      @@rickardjonsson4526 why is it funny? In my country They have machines that precisely balance a wheel. Plane mechanics will have the same device. I just say tyre shop cause most people have 1 in their suburb. Your just guessing. You balance 4 angles. A propeller has 360 angles to balance. A wheel balancer would do that in 15mins. Seems like a waste if time for balancing o, 90,180,270 degrees and not the 355 other angles.
      You should be able to put it at every angle in that jig and have it not move. Otherwise your cg isn't balanced.

      True true but man the top80 is well balanced, i hardly feel any vibrations since i got the balance right. Im 100% buying electric in the future, too heavy for the flight time right now in my opinion.
