1 Answer 1


add a base bone, animate rotation.

add another bone with trackto to constraint to bone.003

add another bone, unparent it, move it as in picture. Add trackto constraint to bone.001.


enter image description here

Note: Of course, bone.003 is just "one" wing. Do the same on the other side or use mirroring.

Lenghten Bone.001 to get a "lower" wing movement.

Animation from side view:

*** UPDATE ***

Moonboots (formerly known as Superman) was right as he stated in the comments that my rig has a dependency circle.

So i tried to fix it:

new result:

enter image description here

new blend file:

Before: Bone1 hat trackto to bone3. Bone3 hat trackto to bone1. That's bad. -> dependency circle

I know added another bone.

Now Bone1 has trackto bone3. new Bone 4 has trackto Bone1 Bone3 has no constraints.

  • $\begingroup$ sorry guys for my late reply. i was asleep last night. anyway chris, is it possible to move the sphere thing on the bone.001 a little bit near the center? because the two planks in the front are going to move up and down following that bottom crank. $\endgroup$ Jan 10 at 4:42
  • $\begingroup$ i already add more motion refferences by two pov. i made it using solidworks but it is really hard for me to figure out when using blender. $\endgroup$ Jan 10 at 4:45
  • $\begingroup$ of course. Just lengthen/shorten the bones to your needs. Although i am not sure what center you mean, i think you should try to shorten bone.003 $\endgroup$
