Sometimes the UAV is slow, sometimes it's fast which is really annoying for the people who are recording some clips, and if this feature is added, this problem will be fixed. As Mitrok stated above, we even face probs while making our own CITy zones, and this suggestion will fix that problem as well and the people will be able to adjust the UAV's speed as well so that they could makes their own CITy zones or record some clips. Good luck with the other votes. Positive
