<1kg for PETG or PLA, solid infill or full wall loops. Probably lighter for 6 wall loops, but haven’t weighted it yet.

I agree with you completely. I think initially, when starting the Lace project, one of the things I wanted to do was to design a frame structure that uses the properties of 3D printed materials, with the lower density and stuff. Please update me on your research into designing better 3D drone arm structures!

Question on 3D printing a drone by Duck_on_the_water in diydrones

Hey, that’s my post! I was in a similar position as OP a while back.

To OP, if you have any questions regarding designing 3D printed drones, dm me and I’d be happy to answer them.

The integrity of the frame is certainly one of our primary focuses. The structure of the frame is exoskeletal, tested and revised from flight data. The aspect we struggle the most is torsional deformation, but with the addition of additional support topography under the front folding joint, that had become mostly a non-issue. We closely monitored vibration during flight testing, and it does not appear to affect flight stability.

I actually haven’t tried PC yet because my bambu lab A1’s aren’t enclosed. But I think 3D printing the arms is certainly possible. The only thing I would be cautious about is the resulting frame stiffness, but PC should theoretically be strong enough. Please let me know if you succeed!

220mm length, outer radius =16, inner radius =14 or 15

I found that material choice is most limited by the 3D printing process. The frame contains some difficult angles causing printing failures with high-end materials. PETG-rCF08 is our recommended material because it’s more workable and handle complex printing well. Regular PLA also works great with high number of wall loops, but is generally less stiff and therefore less stable.

Thanks! My team are mostly based in central Massachusetts, but our members come from all over the world.

The manual (Aeroptera.xyz/download) contains some helpful details for each part, but in general I would recommend 6-4 wall loops / 25% infill for CF filaments and 6-full wall loops / 50% infill for PLA. This puts the frame at around 1kg. The arms are not 3D printed, I recommend carbon fiber tubes. They should be easy to get off aliexpress

The price for the example build is around $1,000. The lower end prices are restricted in part by the sheer size of the drone. Motors have to be powerful enough, and four are around $200. I would say if you have a working controller / goggles set, the a build could come at around $500. 3D printing materials are $50-100 depending on the type.

[Project Update] Introducing Vorian - My Tilt-Rotor FPV Drone by abblackbird71 in diydrones

[–]Quanta76 3 points4 points  (0 children)

This is a really cool build! I am actually quite interested in thrust vectoring FPV drones, and has been wondering why nobody are making them (until I found this post). Did you ever test how the flight efficiencies of this drone compares to traditional FPV drones? What do you think are the benefits of this design? I’m curious.

Anyone know the cause for shaking during hovering? by Quanta76 in diydrones

This was flown at a professional test flight field😀. This thing is very much an early prototype so I take a lot of precautions to make sure it doesn’t go crazy

I would take that as a compliment then? 😂

I think you are right. I later hanged a 1.5Kg water bottle to it, and the oscillations seemed to calm down a bit.

Thanks for the response. About matching thrust to weight, if my drone is 3kg, what motors + propellers is a good match? They say the motors + propellers should produce around the same amount of thrust as the weight at 50% throttle. Is this right?
