Very impressive - all your ornithopters fly very well. I experimented with some based on the Kincade design many years ago but none flew as well as these. I'm glad to see that powering by servo is working so well. I felt this was the way to go with the Kincade design but never tried it. Your work encourages me to have another go. Thanks.

I've to admit that your ornithopters is really thoughful one. Simple design yet very thoughtful. I just realized that only 2 servos are being used

Do you use remote control to fly it or just it's flying but it's own battery life
Hii brother can you please tell me why you chosed such huge dimensions? did you modified the dimensions of real bird? can it fly if I halved the dimensions but maintained the scale?? btw loved your creation!!

Very good work. You have left and right control with powered flight with just two servos! You use wing position to control pitch in powered flight. Is it possible to control pitch with wing position when gliding?
@y.takemura84886 жыл бұрын
Pitch control at gliding is unfortunately impossible.

this can gliding to save some battery power ? for long range

Hi takemura. Are you using 3d print for frame? If you do, may I buy your 3d design? Thanks
@y.takemura84886 жыл бұрын
We do not use 3D printers. It consists of carbon plates and rods

Hi, great job on all these birds! I have a specific question regarding the wing design. I noticed that in your earlier birds (Patapata...) you used a spring-type of mechanism based on a flexible carbon rod that was attached to the body and to the wing and that allowed bending of the wing from its angled position during upstroke (rod not flexed) to a more straight position during downstroke (rod flexed). A very cool design! I was wondering why you have not used this wing design for the servo direct drive bird? Would this not improve the wing efficiency?
@y.takemura84886 жыл бұрын
Servo drive is very low output. Therefore, as much as possible It must be lightweight, you need to make it the simplest and lightweight mechanism.
@jenzinger6 жыл бұрын
I see, so you are saving the weight of the extra rods etc. How long do the servos in your optimized model last - do they provide a real alternative or do they always burn quickly?
@y.takemura84886 жыл бұрын
It is possible to fly for about 3 minutes. However, since there is a lot of fever in the servo, it is cautioned in the summer.

Is this model still using a tail servo? In the video at the end it looks like you are controlling the gliding direction by moving the tail?
@y.takemura84886 жыл бұрын
Tail servo is not used. The servo is only two for driving left and right.

Is there any yaw control by servo movement? I am really curious..
@y.takemura84884 жыл бұрын
By controlling the yaw axis or rolling the body, the rudder surface is tilted and the direction is controlled.

What material did you use for wings and tails
@y.takemura84884 жыл бұрын
Wings are Power Lip T6016 (white) The tail is made of polyethylene bag material

How do you control The servos? Do you each movement or have some special control?
@y.takemura84885 жыл бұрын
The angle of the flapping up and down, and the center angular position of the flapping are set by the program. The throttle varies the speed of flapping. The direction control (aileron or ladder) raises the central angular position on one side and decreases the center angular position of the feather on the opposite side by the same amount as the opposite side. By this operation, the entire torso is twisted, and the tail attached to the torso is The inclination and direction change. The vertical direction (elevator) raises or lowers the tip of the airframe by moving up and down the entire left and right center angle. All variable angular quantities are determined by the fuselage and flight
