Mixing Drone and DSLR images getting two components, can't combine even with control points?

Thanks Erik

This is good to know. So for something like thus (assuming you could scale it up to something much larger) when doing those overhead drone shots are you better having the drone gimbal at say 70 degrees (as opposed) to 90 degrees straight down, and going a bit wider? I’m thinking doing that you are halfway to having a closer angle to the next row of circling drone shots? 

Also am I correct in thinking control points won’t let you stitch “anything” from a scene there needs to be some fundamental connecting “flow” between images? 

Thanks for your comments
