1 3) Carefully bend the second nylon tubeup at a 45 degree angle (using a cigarettelighter). This tube will be the vent tube to themuffler.

1 4) Carefully bend the third nylon tube downat a 45 degree angle (using a cigarette lighter).This tube will be vent tube to the fueling valve.

INSTALLING THE STOPPER ASSEMBLY

1 1) The stopper has been pre-assembledat the factory.1 2) Using a modeling knife, cut one lengthof silicon fuel line (the length of silicon fuel lineis calculated by how the weighted clunk shouldrest about 8mm away from the rear of the tankand move freely inside the tank). Connect oneend of the line to the weighted clunk and theother end to the nylon pick up tube in the stop-per.

When the stopper assembly is installed in thetank, the top of the vent tube should rest justbelow the top surface of the tank. It should nottouch the top of the tank.

1 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.

1 6) When satisfied with the alignment of thestopper 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.

Blow through one of the lines to ensurethe fuel lines have not become kinked insidethe fuel tank compartment. Air should flowthrough easily.

1 9) To secure the fuel tank in place, apply abead of silicon sealer to the forward area ofthe tank, where it exits the fuselage behind theengine mounting box and to the rear of the tankat the forward bulkhead.

Do not secure the tank into place perma-nently until after balancing the airplane. Youmay need to remove the tank to mount thebattery in the fuel tank compartment

1 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.

1 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.

1 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.

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

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

4 3) Double check the balance of theairplane.

4 4) Check the control surface.

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

4 6) Properly balance the propeller.

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

Ailerons : 10mm up 10mm down

Flap : 20mm down

Elevator : 8mm up 8mm down

Rudder : 15mm right 15mm left

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

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

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

*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.

Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 85mm 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 .

1 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 LOCATED85MM BACK FROM THE LEADING EDGEOF THE WING.

1 2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 85mm back fromthe leading edge, at the fuselage sides.1 3. Turn the airplane upside down. Placeyour fingers on the masking tape and care-fully lift the plane .
