Model animations

Hello,

I've got a little problem. I maked an entity model, which has got two-part wings like bat. I set animations to right and left wing swing y-axis, but the two parts move independently and disconnect. I also would like to make body point forward like in bat's case. I've watched official MCreator video how to fix your animations, but it's not very useful in this case.

Thanks in advance and sorry for my English.
