I have created a model of a WWI biplane which properly rotates around the assumed center of gravity. However, since it a tail-dragger, I would like to create an animation where the tail lifts up as the speed increases. This requires me to rotate the entire aircraft vertically around the wheel axle.
I assume that I could do so by making the all of the parts children of the wheel axle and then rotating the wheel axle. But I don't want that to cause the center of rotation for the aircraft to change.
Is there a way to do that?

The solutions below are very helpful.
I may have made this overly complicated by incorrectly assuming how Blender saves models. I tried a very simple approach. To keep things separate, I first created an empty cube at 0,0,0 and made everything a child of that, except the axle. I then linked the cube to the axle, moved the axle axis to the center of the axle and then created an animation where the plane rotated back around the axle. When blender exports the file, it seems that the center of rotation for the model remains at 0,0,0 (where I wanted it) and is not moved to the location of the parent part. Is that correct?
I tried it out in a three.js program and it seems to work okay. The tires are firmly planted on the ground throughout the rotation.
