Quoting David Calvet
Very simple but interesting concept...
Thank you. I had a few other concepts for simple little drones such as this one, but I am having trouble remembering them. It has been so long since I last had them built that I forgot how I made them, or what they were [i]specifically[/i].
(I know it says no HTML, that is why I used "[i]" and "[/i]" instead of real HTML.)
