This project was started in , electronics and control loops. Because I always need a cool project to learn new things, it was clear that something that can fly had to be built.
The project started as a "tricopter-only" project, but as I wanted to build smaller vehicles with more payload capacity, I decided to make some quadrotor, hexacopter and Y6 hexacopter firmwares too. My main interest is to build very small MAVs that fly as good as larger ones (or even better) and that can be controlled by wireless video link. I also experimented with autonomous flight in GPS-denied areas (video), and with GPS assisted autonomous hover (video).

  6. Hi William,
    Any news about this project? Have you measured the real Endurance?

    1. Hi, the endurance is as calculated:

      It flies really great, I am currently putting together a video.

    2. Looks really good.
      I will certainly use the same Turnigy motors than you on an FPV hexa under 250 gr. but powered with a 2S and 5030 props.
      I've already built an FPV quad with the smaller Turnigy motor size (18-11 2000kv 10gr.) with good results (180 gr. giving more than 10 minutes fly time).
      Thanks William for the information and congratulation for your projects. you rock :)

  7. Any news on the video William? Would be interested in a kit. I'm introducing UAV's and MAV's to students in September and will get them to follow your excellent work

    1. Hi! The video is partly finished... I will also capture a FPV session the next days. The Gemini is ultra fun to fly in the park.

  8. Could you post 3-view drawings for this? And could you also post a few pictures of what is under the canopy top and bottom? I would like to see how you arranged the electronics. I would like to make a chassis and canopy.

  9. Nice job, i think you make dream all the FPV community.

  10. There is a question.
    Please teach me how to attach Propeller (4x4.5) to C1822.

  11. Thank you for the advice of a propeller.
    Mushi (clone of GEMiNi) flew.

  12. salut super ton projet je cherche a fabriquer un hexa 1 metre environ monobloc carbone du genre de ton chassis serait t il possible de prendre contact avec toi merci d avance william.

  13. I'd be interested in a frame of one of these. This is beautiful like all your previous frames. I have a BOLT clone that is too large and heavy for its design. You should really look into selling the Bolt and this frame. You'd have a couple orders from myself! ;)

  14. Hello William. I was wondering if I could use the shrediquette gemini's 4x4.5 propellers on a shrediquette bolt?
    Also, is the Hexo+ on Kickstarter the same as the Geminii? What controller does it use?
    With all due respect,
    Nathan

    1. Hi Nathan,
      yes these propellers work on a BOLT, but I had the impression that the 3-bladed Airace propellers have a slightly better performance when used in coaxial propellers. The Hexo+ is very different from the GEMiNi (e.g. 8" propellers), it uses a custom flight controller andI am not involved in the development.

  15. How do we make this? Kit? Design files?

  18. Love your designs. I have a (bashed) Shrediquette MM6...had problem with my FCs in handling it though. Love the GEMiNi looks. Sorry to see TBS is kitting/distributing it though (personal reasons). Keep the neat, unusual, and advanced designs coming!!!

  19. Hi - will this frame be available for sale just via Black Sheep with their electronics?

    1. Yes, TBS makes the GEMiNi. You can also buy it without electronics using their spare parts. But I would recommend their full RTF set because it works really very nicely. They invested a lot of time to find the best stuff.

  20. you choose the wrong company to do business with... TBS are good in Customer support, but not good on pre orders or timing!

  21. I bought the TBS Gemini a while ago and it flies like a beast. Very controllable, too. Kind of what I want: a controllable beast. Only matter that bugs me a little so far: the canopy fixture with the magnets... there must be a better solution to this. I used superglue to fix the metal stripes to the canopy but a mediocre crash made it all fall apart, 10 of 12 metal hooks removed from the canopy. But that is just a minor hick-up with an otherwise great design. Good work.
