Maybe you can explain your "cancelation of lift" theory to the bat. I did enjoy the MS Pain parrot though. Which institute was it produced in?
It's not my theory, it's a well known scientific fact (welll I thought it was). By folding, or twisting the whole wing or parts thereof, the air resistance is reduced on the upstroke. If that didn't happen the lift produced on the downstroke would be cancelled out. That is how lift is produced in a flapping wing, simple. Flapping flight works on that principle in any wing, man made, insect, mamalian and avian. If you look really closely at the bat video you will see the bat folds it's wing on the up stroke and extends it on the downstroke.
The fake flight video can't work on any level, the wings don't twist or fold, the electric motors are not powerful enough, it doesn't have the right range of motion and does not flap fast enough. Something is bothering me about the trailing edge too. If that wing was producing lift the loose material would flutter caused by turbulance over the top of the wing. So it isn't gliding. I say it's clever CGI or he is being lifted by a crane or winch.
You guys are starting to worry me! You sure you aren't pretending to believe this nonsense? Is this the new April fool joke? We all pretend to believe some outragous crap as a clever reversal? If so you have my admiration, you fooled me.
