5) Test fit the stopper assembly into thetank. It may be necessary to remove some ofthe flashing around the tank opening usinga modeling knife. If flashing is present, makesure none of it falls into the tank.

6) When satisfied with the alignment ofthe stopper assembly tighten the 3mm x 20mmmachine screw until the rubber stopper ex-pands and seals the tank opening. Do not overtighten the assembly as this could cause thetank to split.

7) Using a modeling knife, cut 3 lengths offuel line 150mm long. Connect 2 lines to the 2vent tubes and 1 line to the fuel pickup tube inthe stopper.

8) Feed three lines through the fuel tankcompartment and through the pre-drilled holein the firewall. Pull the lines out from behindthe engine, while guiding the fuel tank intoplace. Push the fuel tank as far forward aspossible, the front of the tank should just abouttouch the back of the firewall.

4. Remove the stabilizer. Using the linesyou just drew as a guide, carefully remove thecovering from between them using a modelingknife.

When cutting through the covering to re-move it, cut with only enough pressure toonly cut through the covering it’s self. Cut-ting into the balsa structure may weakenit. This could lead to possible failure dur-ing flight.

Remove covering.

6. When you are sure that everything isaligned correctly, mix up a generous amountof 30 minute epoxy. Apply a thin layer to thetop and bottom of the stabilizer mounting areaand to the stabilizer mounting platform sidesin the fuselage. Slide the stabilizer in place andre-align. Double check all of your measure-ments one more time before the epoxy cures.Remove any excess epoxy using a papertowel and rubbing alcohol and hold the stabi-lizer in place with T-pins or masking tape.

Check to mark sure the wing and stabi-lizer are paralell. If they are not, lightly sandthe opening in the fuselage for the stabilizeruntil the stabilizer is paralell to the wing.

1) We highly recommend setting up aplane using the control throws listed.

2) The control throws should be meas-ured at the widest point of each control sur-face.

3) Check to be sure the control surfacesmove in the correct directions.

CONTROL THROWS.

*If possible, first attempt to balance the modelby changing the position of the receiver bat-tery and receiver. If you are unable to obtaingood balance by doing so, then it will be nec-essary to add weight to the nose or tail toachieve the proper balance point.

With the wing attached to the fuselage, allparts of the model installed ( ready to fly), andempty fuel tanks, hold the model at themarked balance point with the stabilizer level. Lift the model. If the tail drops when youlift, the model is “tail heavy” and you mustadd weigh* to the nose. If the nose drops, itis “nose heavy” and you must add weight* tothe tail to balance.

1) It is critical that your airplane be bal-anced correctly. Improper balance will causeyour plane to lose control and crash.

THE CENTER OF GRAVITY IS LOCATED77MM BACK FROM THE LEADING EDGEOF THE WING.

2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 77mm back fromthe leading edge, at the fuselage sides.

3. Turn the airplane upside down. Placeyour fingers on the masking tape and care-fully lift the plane .

BALANCING.

Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 77mm back from theleading edge. This is the balance point atwhich your model should balance for your firstflights. Later, you may wish to experiment byshifting the balance up to 10mm forward orback to change the flying characteristics.Moving the balance forward may improve thesmoothness and arrow- like tracking, but itmay then require more speed for take offand make it more difficult to slow down forlanding. Moving the balance aft makes themodel more agile with a lighter and snappier”feel”. In any case, please start at the loca-tion we recommend .


33

1) Completely charge your transmitter andreceiver batteries before your first day of fly-ing.

2) Check every bolt and every glue joint inyour plane to ensure that everything is tightand well bonded.

3) Double check the balance of theairplane.

4) Check the control surface.

5) Check the receiver antenna . It shouldbe fully extended and not coiled up inside thefuselage.

6) Properly balance the propeller.

We wish you many safe and enjoy-able flights with your GLASAIR.
