tips apply to any of our free flight ornithopter kits.
If your bird wants to nose dive, check the angle of the tail. If
the tail is not angled correctly, put a small amount of water on
the glue joint, and let it sit until the glue turns white again.
Then carefully reposition the tail. (Don't get water on the tissue.)
#2: If you pick the ornithopter up by its tail, the tail sticks
may break. Repair it with white glue. Fit the parts together as
neatly as possible and brace the tail sticks apart so the tissue
paper will not be loose after the repair. You can reinforce the
glue joint with a small splint of balsa wood or toothpick.
