it was based on an old ornithopter design from awhile back, but I've modified it so much, I'd almost call it an original

I've had many variants and little improvements to the overall function and design, as well as alot of research as to how birds fly, I only wish I had the building skills necessary to implement the mechanics, or if it's even possible. feel free to modify/improve as you wish
my newest ornitopter
