We have planes. We have Aircraft Stands. There are holes in the stands to mount the rod. They have to be drilled out a bit (play on words?) but that's no problem.
We go to look for the corresponding hole on the planes ... and nothing! What are the rest of you doing? Just guessing where the rod should mount? I've seen no pics in the online catalog of mounted aircraft.
I use the Check Your Six stands with Rare Earth Magnets. Holds hard and I only need 8 stands for my air to air games and the same stand is used on micro armor games.
On the Check yoru six forum one guy has taken to glueing steel cap nuts on the pegs of his flight stands. This allows up downa nd banked positions and he doesn't have to worry about magnet polarity.
System has worked well for me.
I pray for Peace on Earth Good will toward men. Till then one round HE fire for Effect!
Centre of Gravity (CoG) is the best spot for mounting (for drilling a hole or glueing the magnet). For small planes it doesn't matter that much, but for heavy ones it does. The bigger the distance to CoG, the more likely they are going to detach from the magnets or flip.
Once played with a guy who had He111s and used magnets to attach them to the stands. They were about 1cm off CoG I think and the miniatures were half the time flipping when we touched them, which was nasty to play with.
A freind has replaced the flat magnets on the CY6 stands with spherical magnets and put a steel nut on the base of the aircraft at the center of gravity. Works really well. You can angle them all around(fighters, I don't think a B17 will bank that well on a small stand)
I drill hole in the aircraft, because the only thing they ever do for me is conduct ground strikes. I use a pin vise, which, despite the name, is a small drill held between two fingers. I would like to second the important of getting the hole at or quite near the center of gravity -- trust me, I can say from experience that you don't want to screw this one up.
Tip: I try to start the hole with a thumbtack -- it gives the drill something to bite into and keeps it from skittering around.
Tip #2: if the rod for the base is too loose in the plane, putting a tiny amount of clay (like kids clay) on the end of the rod.

Those are good ideas, guys. Thanks!
