Whilst playing with my H today at work I was taking some video of some tree work, I decided to take an over head video then finish with a high altitude finish .. I wanted the H to hit the 400' (122m) limit and I was going to stop filming but when checking my altitude it kept increasing 160 ... 170...180m !! I stopped and brought it down but was very surprised I was able to take the H to this height. Has the new firmware update removed the limits ?
