Try a Mini-Stick. They are 7" span, 10" long, with 1/32" square wing spars,
1/64" sheet balsa prop blades and powered by rubber that looks like it came
out of the waist band of your shorts. They fly in circles small enough to
fit inside your apartment, the main limitation is the ceiling. Try to find a
gym to fly in. Let us know where you live, some of us may fly nearby. You
can't do much glider flying under a low ceiling anyway.
