What I noticed is that with the drone in that position, you can really check and see if the second part of the reverse wingover ends the same place the first wingover ended by looking at the building, and you can really check if the second (and third when applicable) loop, etc has the same width as the first (and second) by looking at the stakes on the ground. If that doesn't make sense, what I mean is you can really check to see if the second (and third) time around the loop, etc walks forward or lags behind the first iteration. You can't as distinctly tell if the bottom and top of a repeated maneuver stay the same with the drone in that position, but if that's what you wanted to concentrate on, it would be a simple matter of repositioning the drone.
The overhead loop on the left side of the screen looked to be larger than the the loop on the right side, but that could just be a matter of distortion because of the angle of the drone to the maneuver.
The drone makes a neat tool to check to see if the second (and third) loop, etc directly overlay the first (and second).
Pretty neat tool!
