it is pretty striking how much even a slight steady wind will effect speed.
what i have noticed that makes me think that this is a firmware issue is that looking back on my previous videos, during full forward throttle i could see the arms of the phantom in the video picture whereas now i cannot.
i think there is less of a pitch angle and hence this effects forward speed.
i have no problem giving up some speed for stability but i had no stability problems in the past!
