Put together a few planes recently.
I put a small loop on the top of the plane at the balance point.
I use a length of wire or a TV antenna to hold the planes up.
This way they can fly over the wargame table without having to have a base on the table.
Planes can fly at various altitudes for different missions.
Very high for recon, high for four engine bombers, medium for medium bombers, and low for parachuting and strafing.
This is the kind of wire mesh used for concrete work.
Affix it just below the ceiling for aircraft to fly above the wargame table.
