Lightweight 3D Printed Endurance Quadcopter


I'd like to share a project I've been busy with for the past months. It's a lightweight, small size quadcopter built for long flight time. The AUW of the quad is 85g, and uses geared propulsion with micro DC motors. Controlled by a F4 brushed flight controller, and using a 300mah 2S lipo battery. With this configuration it achieves around 10 mins flight time, which could be further increased with a redesign of some structural parts focusing further on weight-reduction. 

The quadcopter is quite stable and responsive for it's weight and size, and is also suitable for indoor flying. I've designed and 3D printed all structural parts for this quad, including the motor and prop holding assemblies and main body. The arms themselves are build out of unidirectional carbon fiber tubing.


I've got some more photos and characteristics up on my blog, so if you like this check it out.

I'll be posting a flight video of this quad sometime soon, so stay tuned! Needless to say, if you have any ideas or comments I'd love to hear from you.

  • Hey Tommy, I am interested in your copter,What kind of motor/props combo did you use?

  • yannis - Nice work mate!

    Tommy Larsen - I’m keen to know more, and look forward to your post.

  • Hi

    I will soon make a blog post of my project, but here is a sneak peek :)


  • Nice work Yannis !!!!

    Hey Tommy, I am also interested in your sub 250gram achieving over 1 hour flight time :-)

  • Tommy, care to post some specs on your sub-250g endurance copter? Link perhaps? Thanks.

  • That's impressive! I imagine it is 1S since it is a single 18650? What kind of motor/props combo did you use?

  • Nice work :)

    I have built myself a sub-250g with flight time 1hour 12min using 18650 :)

  • That'd be great indeed! are you aware of brushed motor models with high enough kV that can run on 1S? 

  • if you can change motors to make it works at 1S you can try to carry one single 18650, probably you can get an hour with a one Panasonic NCR18650B!
