I've had this twice already. Not sure if it could be my fault, as I am new to the Phantom, but still after the second time wanted to pop a question on the forum. So I fly for a bit, and then it seems like, when close to a tree or building, CL gets confused - and what I though had to be "right" for example becomes something else. I freak out as it usually moves it towards the tree/building. Is this common?
