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.

5. 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.

1. Plug the servo leads and the switchlead into the receiver. You may want to plugan aileron extension into the receiver to makeplugging in the aileron servo lead easierwhen you are installing the wing . Plug thebattery pack lead into the switch.

2. Wrap the receiver and battery pack inthe protective foam to protect them from vi-bration. Use a rubber band or masking tape tohold the foam in place.

3. Position the battery pack and receiverbehind the fuel tank. Use two tie wraps to holdthe battery and receiver securely in place aspicture below. Do not permanently secure the receiver andbattery until after balancing the model.

4. Using a 2mm drill bit, drill a hole throughthe side of the fuselage, near the receiver, forthe antenna to exit.

1. Cut out the switch hole using a modelingknife. Use a 2mm drill bit and drill out the twomounting holes through the fuselage side.

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

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 LOCATED75MM BACK FROM THE LEADING EDGE OFTHE WING.

2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 75mm back fromthe leading edge, at the fuselage sides.

Accurately mark the balance point on thetop of the wing on both sides of the fuselage.The balance point is located 75mm back fromthe leading 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. Mov-ing the balance forward may improve thesmoothness and arrow- like tracking, but it maythen require more speed for take off and makeit more difficult to slow down for landing. Mov-ing the balance aft makes the model more agilewith a lighter and snappier ”feel”. In any case,please start at the location we recommend .

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 must addweigh* to the nose. If the nose drops, it is “noseheavy” and you must add weight* to the tail tobalance.

BALANCING.

*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.

1. We highly recommend setting up a planeusing 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.

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.

PRE-FLIGHT CHECK.

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