tips apply to any of our free flight ornithopter kits.
#1: White glue can be softened with a drop of water. Let the
water sit on the glue joint for several minutes until the glue turns
white again. Using this technique, you may be able to realign any
glue joints that aren't positioned correctly. For example, if the
bird is nose-diving, you may not have the tail at the correct angle.
It should be angled up slightly, not straight in line with the body.
#2: You can also replace the wings on your bird. You might want
to do this if the tissue is badly torn, or if you want to change
to a different color. Small repairs can be made with tape or by
gluing a piece of scrap tissue over the tear. To remove the old
wings completely, follow these steps: First, tear off the old tissue,
being careful not to break the wing spars. Some tissue will remain
along the spar. Moisten it with water. Allow it to sit for several
minutes but not dry out again. Then you can scratch off the old
tissue with your fingernail. Rinse off the remaining glue. Once
the wing spars are clean, you can attach the new wing tissue without
the heavy and unsightly residue from the previous wings.
#3: Lubrication is very important for top performance. The rubber
band should always be lubricated. We sell a non-toxic castor bean
oil for this purpose. To prevent residue formation, you should wash
the oil off with soapy water before storing the rubber band.
#4: 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.
