I have a drone model with separate parts. For example, the propeller and the rudder are two separate meshes. I have parented each to individual bones in hope of later joining them into one armature. Unfortunately, when I select all of the bones and hit Ctrl+J, the bones join, but the meshes change position and/or rotation. How do I join the bones into one armature and keep the transformation on the meshes? The reason I want them into one armature is because I plan on putting the drone into BGE.
Here's a link to the blender file:
