So I took my phantom 2 out for my 1st ever way point flight which went terribly wrong. I went to a large field and carefully set 3 points about 70metres apart at a height of 60metres. Everything seemed great until I hit the go button when the P2 went about 8 metres high flew behind me in the opposite direction and got caught in a tree Grrrrrr. I done everything by the boom and know that all the bird and ground end mods are installed correctly so I'm baffled as to what went wrong....? I eventually got it back out the tree with a 9ft pole. Any ideas what went wrong ??
