How can I find the vecihle skeleton used in vecihle template in unreal engine?

Hello. I am planing to make a plane skeletal mesh. But I don’t know to build a skeleton for a vecihle. Can someone tell me where can I find the .FBX vecihle file used in vecihle template in unreal engine?

You should be able to find the skeletal mesh asset in the Content Browser, right click, and export as FBX.
