@Sourcecode: What do you see as the main benefit of the quick release prop? I don’t get it (but i don’t regularly feel the need for replacing my prop)

To me it seems like a feature i would appreciate if i switch props often, like once a week, if it’s once every two months then a 5 minute job to get a 13mm spanner and replace prop seems OK and you get less complicated and less likely to fail parts.

Larsb & Sourcecode,
I am glad that you addressed my concern from “practical” & “regular e-foil motor / prop” application.
If it works for many days and no issue with loosing propellers due to sheering the pin then great.
I just realized that my “practical” experience is totally different and here is why:

  1. I have been experimenting with high torque trolling motors with lower RPMs.
  2. I have been using much heavier and larger diameter propellers
    For example Poer 1500W motor 2500 RPM, Caroute N300 2100W motor 1500 RPM.
    The Torqeedo Props I have been experimenting are designed for 2000W & 4000W Cruise 2.0 & 4.0 Motors that work with 1300 RPM.
    Please note these are ~12" (300mm-320mm) diameter propellers and not your “regular” puny 6-7" or less diameter propellers (lightweight and for much higher RPM).
    I guess in your application the RPMs are between: 7k and 100k RPM
    Please note that the load is also different. According to Torqeedo specs for one of these props: “For planing with light boats [approx. 200 kg, 24 km/h (approx.440 lbs, 15 mph)]”

Does anyone want to sell this prop?
I wanted to order it, but I got a message that FR stopped selling these props.
Please send me a message if you want to sell it.
Thanks

The FOLDI has moved from the FR catalogue to the … Fliteboard one :wink:
The price has “only” been multiplied by a …2 factor: 495usd or 560€ incl VAT
Not sure the Flite “Foldi” prop could fit a 65161 motor though (M8x25 thread)
The TrueGlide is more affordable in the 250€/usd range.

Yes I have seen it,
The fliteboard motor axle is thinner than the 65161 axle.
Now I run the plastic flite prop and I had to drill the hole.
I have made a small tool to do this on the lathe, but the folding prop is harder to drill out I think.
And after drilling the anodisation is gone in the hole, so the aluminum is going to corrode.
