You otta be ashamed of yourself, nsclcctl
A method that I like to use is get a length of 1/8 inch brass rod and 5/32 inch brass tubing [available at most hardware and hobby stores.
With a pin vice I drill a hole in the bottom of the fuselage just large enough to accommodate the tubing. I usually tape the fuselage halves together to do this.Measure out the tubing so that one end touches the top of the inside of the fuselage and cut it so the other end is flush with the bottom of the outside of the fuselage.
Superglue the tube[top and bottom] into place into one of the fuselage halfs then complete the model as normal.
Get a wooden base and finish it to your liking. Drill a hole in it large enough to accommodate the rod.Cut the rod to desired length and insert.
If you want your plane to be displayed at an angle you can either bend the rod or my preference is to angle the tubing to the desired position in the fuselage before gluing into place.
You can paint the rod or leave it natural
Hope this makes sense. It's really very easy[That's why I'm able to do it!] and it looks pretty darn good in my opinion.
Good luck!
