It looked pretty cool but orientation was a serious problem. It was also difficult to see where we were landing so one landing was in a big puddle!
Attaching the torch to the drone was a little tricky - to start with we had it attached at the front but as you can see from the end of the video, this made it flip over on take-off. We ended up attaching it right in the center.
Flying our quad at night is key to the whole idea of recording bats since they only come out at night. This poses lots of difficulties such as knowing the orientation of the quad from a distance. We had a go in a place where we knew there wouldn't be people walking about.
