While passing by the $1 bins at Target today, I saw "Telescoping Marshmallow Stick".
It telescopes out in 4 or 5 pieces. The bottom piece attached to the handle was about 3" long, but the other sections were about 5" long. The metal seems to be very light aluminum, so the handle & fork might be pretty easy to remove.
I doubt the friction between the sections would be enough to support the weight of something has large as a Wing of War plane. & any significant lateral force when extended would probably easily bend the tubes. But these might work well for microarmor scale or smaller planes or scifi fighters.
