    When you say 3d printed, do you mean consumer 3d printer or professional printer? I would love to try something like this if my Reprap can print it. (when I fix the RR)

    It looks like one of those planes built by multiBillionaires who are bored and want
    to travel around the world using only Solar Powered energy!

    Yes, this was one of the most important design considerations:
    Tractor + 2 Large slow propellers + Throttle management= Quiet

    I love roaring and buzzing around with my flying wings, but definitely they attract too much attention in some places...

    It's the amazing White, Strong and Flexible material from Shapeways. Basically laser sintered nylon plastic. I spent quite a long time looking at hobby grade 3D printers, but I had several issues:

    - The main one was the size of the parts. Some of the parts are 60cm long, and none of the home printers could do the job.

    - The material was important too. The combination of strength, detail level and flexibility from this material is hard to find in the hobby grade printers.

    - Laser sintered nylon powder means that the only design constraint is that you need “holes” to empty the nylon powder once printed. But nothing about supports that you need to remove after. Just as an example, the design of the retaining clip for the carbon tube booms would have been impossible to make with another technology.

    You will probably recognize the dome. I am using the Rangevideo RVJET clear dome and Gopro Pan&Tilt gimbal. I just designed the main fuselage to fit their parts. Useless to reinvent such a brilliant design, especially considering that you can order it separately from RV at a reasonable price.

    I bought one of the very first RVJETs, and I ordered at the same time a couple of extra gimbals and quite a few clear domes.

    Juan are they counter-rotating folding props?

    Do you have a secret source for them?

    I've told you before but I'll say it again - it's stunning.

    The moment you get this on kickstarter I'm there!

    Looks really cool, but can you explain whats going on with the tail feathers, what was the reasoning behind choosing a 'v' and whats the central pod on the tail all about? Is it to house something?

    Very good point, Ian. I spent a long time looking for them, but it seems the only available are these:



    Too small and cheap plastic. So, no, they are not counter-rotating. As far as I understand, for twin motors that far away from each other, torque will be negligible.

    Thanks, mate. A bit early for this...
    Let's make it fly first!

    Several reasons:

    - It's a natural choice when going twin motors and twin boms.
    - It helps making coordinated turns in planes without ailerons.
    - It is very protected in landings.
    - The central pod houses the EzUHF, as far away as possible from all the noise sources (camera, ESCs, VTx, etc.).
    - The two antennas of the EzUHF fit very nicely inside the leading edge of the stabilizers.
    - I like it...
    - Makes sense with the name... SkyTrek, StarTrek...lol

    Actually, more (exactly) like one researchers designed when making a UAV capable of 24/7 flight on Solar power (and some batteries).

    Tell me you need beta testers?

    I've been looking for months for my next plane. Wings are the closest that come to a one piece easy to carry but they have lots of downsides, most being the noise and poor footage (wagging).

    I want something like my Skywalker 1900. Quiet, long flight times, perfect of mid range cruising and covering good amounts of ground. This looks absolutely perfect.
