Recently my phantom will not hover or hold altitude. It always wants to climb. I have recalibrated the compass but that did not work and always fly with enough satellites. The only software update I have made recently is with the Vision App on my iPod. I can see on the app that the altitude is changing (decreasing) while the Vision is sitting still with engines off. I am guessing this is why is it continually climbing as for some reason it thinks it is descending. Any ideas?
