Got my new Phantom today this one works fine. Had an issue of not connecting to my Netbook. Had an old Windows XP laptop. And the naza Software worked through it. Out of the box did not need calibrating, other then the compass. Did a basic calibration and advance anyway. Did not bother with the ICO, don't think it's all that useful, unlike the AR Drone, there system is, and don't have to be over 10 feet away for it to work, so don't really see the point turning it on. So, so far it's working fine. Only around 5 days, from ebay and no extra cost, as a good exchange rate at the moment for us.
