GLIDER ADJUSTMENTS:
If glider dives, remove clay weight from cavity.
If glider stalls, add clay weight to cavity.
If glider turns too sharply, make sure it is balanced
span wise (from side to side). If it is not, add
weight, in small amounts, to the light wing tip until
nearly balanced.
The glider should perform a large, gliding circle
during descent.

B. Add or subtract clay weight until
glider balances between 7-1/8" to
7-3/8"

WITH MASKING
TAPE
A. With engine pod removed from glider, aim for a spot about
50 feet (15 m) away and toss glider straight out at eye level.
B. Observe glide carefully. Make adjustments a little at a time
until you are satisfied with the glide.
NOTE: Test the glider only on soft, grassy surfaces like a sports field
or lawn so that you don't damage your model.

DOUBLE-SIDED
DOOR TAPE
Once you are satisfied with the glide, remove the tape that holds the
clay in place, being careful not to dislodge any of the clay. Remove
backing from double-sided door tape and apply tape to plastic door.
Remove other side of backing and attach door to fuselage, pressing
door firmly onto fuselage and securing clay weight in place.
