Model information
Description
A folding propeller set designed for RC planes, including various hub and propeller size options. The author used these on upscaled (130%) versions of the Nucking Futs pylon racer.
Printing Instructions:
- To achieve maximum strength, print with 10 perimeters. This orients layer lines along the perimeters to increase strength at the blade root.
- Print with the leading edge of the blade facing the print bed.
Author's Report:
- Materials: The author states that when printed with PLA or PETG, it withstands several hundred Watts of input power. The author notes 'Best Material would probably be PA-CF'.
- Performance: In a max power test with 8.5-inch blades printed in PLA, failure occurred at roughly 1000 Watts. The author suggests that if printed correctly, 300 Watts (approx. 30A @ 3S, 20A @ 4S) should be safe and durable.
- Caution: The author warns: 'Do absolutely NOT stand beside or in front of the Propeller when you first test it.' and 'It can cause serious harm when the blades separate!'

<p>This is a folding propeller I created years ago. I flew this propeller myself on upscaled (130%) versions of the Nucking Futs printable pylon racer.<br>Link to Airplane: <a href="https://www.thingiverse.com/thing:3358880 ">https://www.thingiverse.com/thing:3358880 </a><br>Please give credit to the designer of this plane, it's absolutely amazing and it flies very well. <br><br>There is many different Hub and Propeller sizes.<br>When printed with PLA or PETG it withstands several hundred Watts of input power no problem. Best Material would probably be PA-CF.</p><p><strong>Edit 2025-06-13: </strong>There have been some questions on how to print. To achieve maximum strength, print with 10 perimeters. Like this, the layer lines are oriented along the perimeters which increases strength, especially at the blades root. Print with the leading edge of the blade facing the print bed.</p><p><strong>Max. Power Test:</strong> Below is the video of a max. Power test I did with the 8.5inch blades printed in PLA. The point of failure was at roughly 1000 Watts of input power. So if printed correctly, 300 Watts (ca. 30A @ 3S, 20A @ 4S) should be safe and durable.</p><p><strong>Caution: Do absolutely NOT stand beside or in front of the Propeller when you first test it.</strong> I highly recommend testing it with more power than you will finally need. It can cause serious harm when the blades separate! </p><figure class="media"><oembed url="https://youtu.be/5OvdSDFOB-g"></oembed></figure><p> </p><p> </p>
