If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the
model in a cool place will let the wrinkles disappear. Otherwise, remove
wrinkles in covering film with a hair dryer, starting with
low temperature. You can fix the corners by using a hot iron.

In case your E-retracts can not open (to extended position) after closed (retracted position). Please make sure
your E-retract wasn’t stuck when it close. Stuck, this problem maybe from the struts, when E-retract close, the
body of the struts, it touch to the body of E-retract and it make the E-retracts can’t close 100%, or maybe the
wheel touch to the edge of the wing or plastic cover. In this case, after check all the problem above, please use
your finger push the steel wire (or struts in case you use struts) down in the same time you click “ON” the
gear switch on your transmitter.
When the E-retract open (extended position), please solve the problem to
make sure it always close and open in flight.

1-Trial fit the vertical stabilizer in place . Check the alignment of the vertical stabilizer. When you are satisfied with the alignment,
use a pencil to trace around the right and left of the stabilizer where it meets the fuselage.
2-Remove the vertical stabilizer from the fuselage. Using the sharp hobby knife, carefully cut away the covering inside the lines
which were marked above.
3-Spread epoxy (30 minute) onto the right and left and bottom of the vertical stabilizer along the area where the covering was
removed and to the fuselage where the vertical stabilizer mounts.
4-Install the vertical stabilizer into the fuselage and adust the alignment as described in steep 1.
5-Wipe off any excess epoxy using a paper towel .
Allow the epoxy to cure before proceeding to next step.

IMPORTANT: Flying your model at these throws will provide you with the greatest chance for successful first flights.
If,after you have become accustomed to the way the F-82 flies, you would like to change the throws to suit your taste
that is fine. However, too much control throw could make the model difficult to control, so remember, “more is not always
better”.
