    Nice choice, so are you going to be running 8" props instead of 9" due to the faster RPM? I'm now toying with the idea of going onto 4cell lipo's (14.8v) for some extra kick and power

    I've got 1000kv motors on mine, and get around 6 - 7 minutes of flight time with it using a 3S 2200 LiPo. Currently trying to sort out a Loiter problem with it; whenever I put in Loiter mode it just goes off in all sorts of directions, might be a compass issue. I'm now considering the FPV gear, but doing my research on that kit first.

    Best of luck, post your Vids when it's flying.

    That's a great flight video Pete, some fast and brave moves for LOS flight. I see your using the Ali motor mounts, that's a great upgrade for the X525frame, before these were available I ended up just mounting the motors straight to the arms and it makes such a difference. Keep the video's coming

    Looking at some 8 x 4.5 props but only running 3 cells as that's all the motors are rated for.

    That's excellent, it should sound and react like its on rails, do you have a link to your motors you can share?

    As for RC Tx's, I would suggest the Turnigy 9x, you can flash opensource firmware to it so it then has features that Tx's that cost hundereds have. I was looking at one of the 9x's but then I discovered I can use my Spektrum DX6i with other TX modules like EzUHF etc by using the training port...sweet!

    Thanks - Just uploaded another one yesterday as I've finally got my Loiter and RTL problems resolved. (QuadCopter APM 2.5 Loiter & RTL On Board - YouTube)

    I'm looking into FPV now, but I just stumbling at the price of a decent set of FatSharks! Can't believe they cost so much. Frustrating.

    Yes, using those mounts as I crashed it not so long ago and broke one of the original mounts - they're not bad but have bent a couple during some other 'incidents' but can be bent back into shape in a vice quite easily ;P

    I tried mounting the go pro on a couple of tubes running from the centre, in an attempt to bring it forward slightly and mount the battery on the back, unfortunately it introduced so much Jello on the picture that I ripped it apart again and went back to the original configuration.

    I know what you mean about the price of those Fatsharks, there are alternatives, some around the same price and some cheaper but you will be loosing quality and FOV on most of them. I saw it as, well I can use these on anything else RC I want to FPV, I could use them for gaming (not very good resolution for that) etc and I knew if I brought a lesser pair of goggles then I would always be wanting the better ones. I bit the bullet and got the FatShark Attitude SD goggles with their vTx, its an amazing pair but some people do not get on with the rubber eye sockets, but if you can handle swimming goggles then you can handle these.

    I found for the under slung rig for the camera, if you get some strong/thick rubber/foam and cut it into four squares and put that between the frame and your rods and then attach zip ties around the rods and through some holes (where the pads are) in the frame to lock them together then you will have a lot less vibration, no need to fix or lock the rods onto place as the zipties do that and dampen some vibration as well as the rubber pads. That way you can push the camera way out front and counter it with the lipo on the back....might help

    @JAB1a what's the view from within the fatsharks like does it look like you're actually there or is it like watching on a big tv? I read about some of these glasses that say they give the impression of watching a huge screen floating in the distance.

    It is like a huge TV screen floating in front of your face but as soon as you start flying then your peripheral closes down and you are completely immersed into what you are seeing. The colours and quality is amazing with the right camera attached, you can spot a telephone wire in your path at about 50meters so it has good resolution for flying. You can always do FPV without the goggles by using a computer monitor or something so you can still fly FPV but its not as fun or immersive. The Attitudes allow you to change the angle your eyes view the screen where as all the others are fixed which might be an issue if you have a big/small head

    Nice lid, Tupperware is so light, cheap and bomb proof that its perfect for protecting your electronics. The frame is looking very good, I like those motor mounts...did you make them?

    @JAB1a yeah 3D printed motor mounts and main cross member, on top of the main cross member is a laser cut space so the Tupperware lid sits flush and then inside the lid is another laser cut spacer and then it's bolted through all pieces in a sandwich, plastic box cost the princely sum of £1

    Waiting for the Bluetooth board, sensor board and speed controllers to arrive, after that all I need to buy is batteries, charger, props and radio gear.

    Wow these seem to be the right spec, 2 LCD's so you can view 3d films is good, 31deg FOV is better than the attitudes at 30deg, not sure on the pixel density for clarity but they must be about the same, no video Tx or Rx or head tracker so that's an extra cost to add to them, if you use 2 vTx's and 2 cameras you could fly in true 3D vision I guess which would be cool.

    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)
