Multi pitch prop for FlipSky 65161 or Maytech 65162

It was just an exercise for my dad (and me), but here are some pictures of the 3 blade prop.
We also made the blade a little bit thicker.

I would love to share the .step, but as this is not my design I am not sure if I get into trouble by doing so.

I have printed other props such as a Flite “clone” that I found here but the result although likely good enough was not as stiff as the real thing.

My viewpoint is that this variable prop doesn’t have much use to us other than an enjoyable exercise in printing and playing around with. Personally I wouldn’t leave shore with it unless I had a buddy with some type of tow vessel in case it broke.

The reasoning behind that is we have a very good - inexpensive efoil prop in the Flite product. It’s likely that during its development they tried different pitch’s etc and found the optimal one for the Flite motor. We just lucked out in that it works well with the classic 65161 type motor many of us has chosen.

It has been fun for me as well. Nice way to expand 3D skill is to take something already done and tweak it a bit.

I applaud your reservation on not publishing an alteration without explicit permission from the original designer

I remember somewhere reading that Dave@flite did exactly that test lots of props before the release of their product. It may actually be on this forum early days.

Yes, did exactly that. Many of us have enjoyed the fruits of his labor and tooling mold

The prop design is 90% based on a prop thst i iterated myself early in the project looking for peak efficiency (in conjunction with the drive train development). I printed a prop nightly and then tested about 30 props with varying pitch to see how low i could get the current draw in our target speed range. I can ride with about 20amps, and I am 90kg. Despite doing all that work, I don’t actually know what the pitch is! The final prop design for tooling was developed by a hydrodynamicist in our t…

Why oh why do I always end up at https://foil.zone/ when I click a link on this forum!

Example. I clicked the link @S_Roger posted, and it redirects to foil.zone.
I want to read the thread in that link, and not go to the main site!

When the link is put in a quote it works fine for me.

Same thing for me since the forum moved from efoil.builder to foil.zone a couple of years ago. Looks like some javascript issues.
As you’ve just shown, a link between inverted commas or preceded by a single works if you’re the author. Most are simply not aware of that or don’t bother when they write.

What I do is copy paste the post first words in the search function and voila…

That’s what I do too, but it’s 2025 now.
A link should take you to the intended post

I was a bit lazy and just stuck the link right in there. What does work is the hyperlink function. Select a piece of text and add a link to it, and that always seems to work.

Please do not get me wrong! I’m not blaming you!
