    Sorry about bringing back an old thread, but I've been doing some materials research and would like to know more about the manufacturing involved in making this quad,

    I'd be really thankful if someone could shed some light on the same,

    " DIY - onboard - Balancer"

     I am not sure what this is. Do you mean the radio with telemetry monitoring on the laptop.

    Dome, Cap looks good. Thanks.

    P.S.: What about an DIY - onboard - Balancer ?

    A quarter or 1/8 turn locking mechanism that locks the whole center mechanism is at the top of my list but some of my original attempts have proven unreliable. That will be real quick. Still requires some work to get a reliable repeatable device designed.

    I prefer the battery locked in like you have it but maybe some better thumb screws or the electric screwdriver would be ok.

    You do have to unscrew the lid to access

    the compartment where the batteries are stored.

    But it seems pretty easy to me. I keep a palm size rechargable drill in the case. I do the battery change now like a pit crew, so it only takes a minute. The way I designed the lower hull allows for a power distribution board to be screwed to the bottom . I then formed the two shelves forward and aft to support one or two batteries side by side. I could form the bottom so that it would allow the batteries to be velcro'ed or strapped to the bottom of the hull

    Is it easy to replace the batteries, or do you need to dismount the apm to gain access?

     

    Very nice design.

    Hey Everyone,

    Sorry I am just now speaking up. I am glad to see you like the design.You can see in the image the lid fits with the GPS in place. I often fly with it off if it is not raining. It would probably be a good idea to protect the GPS. I imagine with the uBlox I have coming in the mail I will be fkying with the lid on rain or shine.

    I had also planned on using an arming plug like the one you see here until I came across the switch while picking up some fuses.It was specified for 25 Amps @ 125V, which seemed reasonable to me. But I think I see it as a weak link. I think I will probably go back to the arming plug.

    HUGO Specs:

    • 555mm prop to prop distance
    • stock motors 2212-13 1000kv (I run one or two 3s 2650 mAh lipo)
    • 10x 4.5 SF props
    • 25 Amp esc 3692585086?profile=original
    • Center hub accomidates APM Ver. 1 or 2 With or without enclos
    • ure.
    • also fits MultiWii, KK boards, Naza FC.
    • ARF and RTF models will include the APM 2.5, power dist.,ESC's, motors, props,battery and frame.
    • I plan on selling the frame alone for $145 plus shipping
    • The ARF and RTF are still to be determined as far as pricing, but soon.

    I will try and get an  expected shipping date soon.

    They don't really need to handle as many as you might think. The rating is usually given assuming the load is on but in this case nothing is drawing the amps until the motors are running. Then the switch can handle more amps since it's contacts are closed.

    Mark, is the Aerotestra for sell? Didn't see anything about that on the blog.

    As boards mature its going to be all about looks and simplicity.
