Oh this works better so people can get in on the convo.  From where we last left off I'm just gonna say you know the about the glues so I'm not gonna even mess with a physics dude, you know your stuff. LOL

But you mentioned something about gluing the rods to the model.  You mentioned in your vids that you don't want to drill into the model or anything to mess with it so why don't you make it so that it's a "cradle" stand where you can just set your model on it.

Here's another idea.  Put a magnet on the rod and in the model.  You can cover it up with clever scale modeling skills.  Heck, if you can be creative and find strong enough magnets, then you can put the magnets into different area's of your model to be able to move it to display it at different angles.

Wargaming techniques carrying over.  People use magnets on figures in their arm sockets so they can switch out weapons that the figures carry in a battle.  This can be done the same way if we can find some strong enough magnets. I'm not sure how heavy the model itself is... in fact, I wouldn't mind making a few for my planes... hmmmm....
