facthunter Posted February 18 Posted February 18 They tilt their tails and Have wing slats and they are Ornithopters. No Plane will ever be as good. Nev 2 1
onetrack Posted February 18 Posted February 18 The answer is in the link below. Their whole body is very flexible, and their tailfeathers do multiple jobs. I took a shot at a Ringneck parrot with a .22 many years ago, and the bullet grazed the parrots body, at the base of his tail feathers. He took off, but couldn't fly properly, wobbling all over the place, and he ended up making a crash landing. It was very obvious he'd lost the ability to control his tail feathers. https://aviation.stackexchange.com/questions/100763/how-do-birds-coordinate-their-turns#:~:text=2 Answers,1

willedoo Posted February 18 Posted February 18 A dry grass straw that is; you'll have a lot of trouble trying to get a soft green one up there. 1
Grumpy Old Nasho Posted February 18 Author Posted February 18 Watch this model ornithopter turn continually to the left without a trimmed rudder. Amazing! 1

facthunter Posted February 18 Posted February 18 Maybe the ornithopter is bitter and twisted and we can't have it turning left can we? I think it's biased actually. LH circuits are preferred, Nev 1 1
facthunter Posted February 19 Posted February 19 Planes don't steer with the rudder. They do it by banking and directing the Lift forces in the Intended direction of turn. I suggest birds are not much different, Nev 1 1
