    all Carbon Fiber quad (almost)

    I've been having tons of fun flying my smaller quads around that I've only flown my big quad 2x in the last 8 months.
    So I thought i'd rebuild it and make it big enough so that I can turn it into an X8 or even octo and then put my dslr on it and do some aerial photography

    for now, i'm sticking with just 4 motors so i can get a feel for how this flies, and then i'll add more motors.

    this frame is all carbon fiber and g10/fr4(motor mounts)
    I even turned my dremel and dremel drill press into a manual cnc machine to help cut the CF disks and arms. It worked out very well.

    Dimensions:
    motor to motor: 22inches
    weight(frame+motors+2200mah battery+8" gws 3blade props): 750g
    Estimated weight when its ready to fly: less than 900g

    now for the pictures:





    What do you guys think?
    I'm looking to get some 10mm x 10mm square aluminum tubing for the arms, I don't think the CF arms will work well under compression from the center plates and motor mounts.

    It looks really nice! Whats the material you used on the center-plate?
    And the motor-mounts, why are they mounted like that? I see that a lot, but i don't really know why its done like that..

    The center plates are carbon fiber disks from ACP composites
    motor mounts are designed so I can attach 2 motors per arm, one on top and one on bottom. This is for a future upgrade to the quad where I will have 8 motors, 2 on each arm for an X8 configuration

    the motors are BP A2217-9 motors

    here are some more pictures of the completed quad
    total weight without battery; 874g
    battery + camera is just over 1kg






    The camera mounted on the quad is a Veho Muvi HD7 only $100 on amazon and the video quality is amazing, its just as good as the gopro

    Looks very clean and nice!! But I wouldn´t use these small 3 blade props for that big quad - I would go for the regular eep 1045, with stronger motor the 1245

    I have some 10x4.5 props that i'm going to put on before I fly, I just didn't feel like taking the 8" props off.

    First flight in about an hour. I need to debug my multiwii board and figure out why its not working anymore. I've got a feeling the wii sensors are bad.

    Here is some onboard video from today's flight.
    I put the 10x4.5 props on it and it flies really well without tuning any pid values. I think some minor tuning will make it perfect.

    I should have cleaned the lens before i started the video, oh well, i guess i'll do another video tomorrow afternoon when its not getting dark outside.
    anyways, enjoy the video!

    Here is another video from yesterday. it was pretty windy but the quad handles it pretty well.
    I still haven't done any pid tuning, I think i'll tune it a bit today

    This is the highest I have ever flown any of my quads, i think I can go higher but was scared the wind might take it away and land it on someone's roof.
    There is a big park not too far away, I think i'll take it there this weekend and really get it up high.
