    The GPS connector is there a right way round for it? Is there a right way according to the colour of the cables. After assembly and 6 minutes on the ground I have no satellites showing at all. Even with the foil mod.

    There is only one way to fit as it is keyed, are you sure it is connected properly?

    I appreciate the quick reply. Thanks for that I will take it apart later and do a check. What a dope if I have forced it against its key way!

    I took the Phantom apart and found although it is impossible to install the GPS cable the wrong way round I must have not seated it corrrectly. I had added some new longer landing gear legs to the Phantom ( note it is now much easier to remove the screws of the shell with the longer legs which is a bonus) which required re-setting the compass wire. Also I installed a new version of the 7th Channel modification hardware. Plus I had fitted the lens hood as advertised on the forum which fitted perfectly. On settting the Phantom up for a first flight in my garden I could not obtain any more than 4 satellites even after the battery was run down to almost a half. The phone was indicating a compass calibration was needed but could not do this until the satellites were obtained. I went to a local park and set up again and after some minutes I obtained 6 satellites upon whihc I calibrated the compass. I was now set in NAZA mode with both switches upward in GPS position. The take off form the Helipad was OK but the Phantom acted as if I were in maual mode ( I have never beeen in manual mode so it may not be right) I was constantly having to apply forward or sideways control (the wind was quite brisk and blowy) it would not settle into GPS lock it would seem. However at last after a couple of minutes all was well. Experimenting with atti and GPS mode the Phantom reacted instantly to the commands. The new 7th Channel mod worked fine obviating the need to make the changes on the phone. After viewing the pictures as can be seen in the video the lens hood obscures the screen slightly. I cannot think why as the maker must have tried it first before manufacture. It is easily cure as deomonstrated maybe you could use the narrow setting in the camera. Due to windy days at the moment further experiments wil have to wait. The propeller interference lines are well and truly cured however. Landing back on to the helipad will need more practice but it showed that a tumble over on to the prop guards by the Phantom causes no damage. I have posted this video with an on the screeen explanation. https://vimeo.com/104634617?utm_source= ... QwMXw3NzAx

    Learn to hand catch. Zero tip over issues = long life propellor blades!

    Not sure why the quad was moving around after take off but maybe try a calibration in the assistant software? check all the connections again too as you say the gps cable was not seated correctly. Can you tell me where you purchased the lens hood?
    I hand catch every time, and only ever landed it once i think in 60+ flights. No worries on accidental tipovers or worst still damage to the gimball.
    Its up to you if you use the prop guards or not, i used them for a couple of flights when i had the fc40 and after removing them i noticed how more agile the craft was especially in the wind, some say they can also contribute to vrs. Never fly too close to anything and you will be fine.
    Also had the wider longer landing legs on the fc40 but again were not needed as i hand catch, you will not be able to find a case either to fit with the legs on unless you build a custom one but then the case would be too large.

    The hood is from Shapeways its on the board advertised. I am going to try the hand catch I think especially in the wind.

    I agree with happydays, hand catch is the way to protect the bird, gimbal, camera, and all things precious to us:)

    I try to bring it down directly over my head so I can just reach up and grab the landing gear. Then apply full down throttle for a few seconds to kill the engines.

    I figure if it's overhead and secides to get laterally squirrely, I have a better chance of dodging and/or giving it up throttle so avoid personal contact. So far I've been successful every time. I do admit I don't fly in winds much over 5-10 mph.

    Just go slowly so you don't end up with a face full of props :cry:

    Also, make sure that you execute the manoeuvre so that the wind is coming from behind you - if there's a gust it will blow the phantom away from you and not into your face...
