Mars Ingenuity Helicopter

A 1:1 scale flying model of the Mars helicopter

Similar projects worth following
I've always wanted to try 3D printing an RC helicopter. It's a great design challenge to make the swashplate and transmission assemblies. I also wanted to make a small-scale model of the Mars Ingenuity helicopter, so why not combine these two project ideas? Oh, and why not build the Mars helicopter at 1:1 scale so I can have my own flying Mars helicopter copy here on Earth? So that's what I'm doing.

My goal is to 3D print as many parts as possible. The blades will be made of foamboard and I'll try to keep the assembly as light as possible to reduce power requirements and stresses on the blades. While not staying true to the real Mars helicopter design entirely (very complex rotor head design), I would still like to see a large, flybarless coaxial heli flying by the end of this project. Stay tuned...

Enjoy this project?

If you need some inspiration for the swashplate, check out my deep-dive into Ingenuity: https://hackaday.com/2020/09/02/an-up-close-look-at-the-first-martian-helicopter/

Thanks Dan, awesome article. My version will have a far more simplified head design (simpler, not 'better') to see what I can get away with here on Earth and with my current resources. The only thing this will have in common with the real Ingenuity is looks
