    I am still weary of these as I have not heard much about them. Quick search revels they go to a blue screen if interference is encountered......which is not good for FPV, also light pollution is bad with them so you will have to make a sun guard like this maybe.... Ski Goggle Mod for Vuzix 920 Wraps for MR - RC Groups, I don't think these have IPD adjustment aswell which means your brain is going to have to work hard to make these immersive to make it look like one screen.

    Still interesting

    At that price its probably worth a punt but I myself would still hold out for the FatSharks as I have read a lot more reviews about them than the Vuzix

    Fatshark Attitude SD:
    Full color LCD LED backlit Kopin CyberDisplay
    922,000 pixels binocular display (640 X 480 VGA)
    You can plug a head tracker in to them and I found one on ebay for £10 yesterday.

    That looks wicked, you won't have any trouble spotting that in the air, great job!. Not sure about the landing gear, I can see after a heavy landing these might buckle up underneath but time will tell. Lov'in it Ben

    Yup, although the modification of my design for this landing gear is a set of pylons similar ot these which have removable tips so you could bolt anything you wanted to them.

    Perhaps some big floats?

    ESC connectors all soldered on and mounted to arms with good ole cable ties.

    Just occurred to me though that I've mounted them to the bottom of the arms, wondering if top would be better for additional cooling from prop wash? @JAB1a

    @plexer It really depends on how hot the ESC's get, mine are 20Amp ESC's and rarely pull over 15Amps from them so the temp is always quite low. I didn't mount mine on the top or bottom of the arm purely because of the prop wash which will cause low frequency vibrations each time a prop goes past, so I have mine vertically on the rear of each arm and close to the frame plates, that way if I crash head on then they are protected and are not in the prop wash at all but still get a good air flow.

    Same goes for the wires, they are all run down the back of the arms for safety and keeping them out of prop wash. Vibration is definitely your enemy with multicopters.

    P.s I also added a 2mm thick slither of foam between the ESC's and the arm before using zip ties to deaden any vibrations which will cause the electronics in the ESC to fail prematurely and your beautiful Quad to plumment to the ground in a twisted mess lol I've seen it happen before

    @JAB1a I did wonder about adding some foam and actually unless I fitted 12" props the escs won't be in the prop wash anyway as they are quite close to the centre frame piece.

    Thanks as always .

    @JAB1a Your video is really amazing!

    Just to let your know I'm also starting my quadcopter based on your recommendations (since although I've been in the r/c car racing world for a decade, I know nothing when it comes to flying things), and that I have an ambitious side-plan for it...

    Thanks!

    Thanks for your comment @flink

    I look forward to seeing your progress, the links in the first post are mostly out of date now but the items are still called the same if you do a search on ebay or somewhere.

    Don't hesitate to ask any questions if you need something cleared up. Good luck
