Testing 12 Ultra Efficient Electric Boat Propellers

Airshaper Simulations:

[Freytraz]

The only reason I don't submit a propeller that would absolutely humiliate all other entries is that I don't understand propellers, have no knowledge of fluid dynamics, have a beginner-level capacity on modelling and don't know enough maths to learn it all in a short period. Thinking again, that's 5 reasons.

This is MajorHardware's PC fan competition but for RC hobby nerds, love it

[Tyr]

the Race to Alaska just started yesterday. It might be something interesting for you to do next year, designing a droneship that can make it the whole way

[jamesm]

Love this! Small thing, the new graph is really useful but the colors of each prop change each time you showed it which made it hard to compare props.

[Flesh_Wizard]

Spanmaxxing has got to be one of the most aesthetically pleasing propellers I've ever seen

[Madvizion]

After consuming so much trash media, i look so forward to awesome meaningful videos like this.
Keep it up you are saving minds every where

Man, I am absolutely loving this series. Thanks for putting it on and spending so much time on it!

[dannywastaken]

This is just the right ratio of video and pretty graphs. That editing balancing act is as impressive as the props. Well done Daniel!

[pieman]

All props to you bud, this stuff is beyond me / over my head. Been watching your videos for years your parents must be proud, decent kid curious how things work and then try make them better while enjoying life. Keep the projects coming I will get my head around it some day, heck I don't have a 3D printer or do CAD but you have a gut feel what will work. Amazing designs keep them coming.

[veizour]

Congrats to Spanmaxxing for current first place! Very neat project.

[andrewnguyen]

"that looks about right" sounds about right to me!

[sikhswim]

This is by far the most exciting competition I’ve ever seen on YouTube!!! Can’t wait for s1s3

[JoeJJohnsonII]

Some of the names for these props are amazing. Forever alone takes a special top spot for me.

[boppins]

This is a fun series, and I don't even boat! I love your explanations and how you don't just toss away design ideas, but rather explain how they could improve or maybe some other factor is limiting them. Definitely should include details on the motor for your next competition - looking forward to it!

[andydelarue]

Wow thank you for the best smartest competition online, It’s a pure joy to listen, watch and see competitors wild great ideas run thur your test bed. Don’t stop now this is great

[wessonw-tdkh]

Mad props to this series!
I enjoy the community involvement element!
It is incredible how technology has opened doors to design, share ideas and collaborate. Huge potential for innovation from this format.

[danilopmaciel]

For a better view, a table at the end of the video with the propellers with the best performance would be nice. Thanks for the video. Very good.

[kylethatcher]

Great video, as always! I just want to say that your brand integration is the best out there. You made meaningful plugs for several companies and they were all appropriate and didn’t feel forced at all. I hope it’s beneficial for both parties, and I hope it results in more amazing content in the future.

[chemicalcorrosion]

Quite the rabbit hole you’re going down here. Can’t wait to see where it leads!!

*Props* to the Palnovic propeller guy

There's nothing wrong with being confident and ending up wrong, important thing is he fixed some of the things wrong and tried again

I think that's really cool :>
