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 measurementsone more time before the epoxy cures.Remove any excess epoxy using a papertowel and rubbing alcohol and hold the stabilizerin place with T-pins or masking tape.Epoxy glueMark lineBottom side 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 coveringto remove it, cut with only enough pressureto only cut through the covering it’sself. Cutting into the balsa structure mayweaken it. This could lead to possible failureduring flight6. After the epoxy has fully cured, removethe masking tape or T-pins used to hold thestabilizer in place and carefully inspect theglue joints.

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.18

Wrap the receiver and battery pack inthe protective foam to protect them from vibration.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 tohold the battery and receiver securely in place.As pictures below.Do not permanently secure the receiverand battery until after balancing the model. 4.

MIDGET MUSTANG-EP - Item code: BH81INSTRUCTION MANUALBALANCING. 1) It is critical that your airplane be balancedcorrectly. Improper balance will causeyour plane to lose control and crash.THE CENTER OF GRAVITY IS LOCATED80MM 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 80mm back fromthe leading edge, at the fuselage sides. 3. Turn the airplane upside down. Placeyour fingers on the masking tape and carefullylift the plane .Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 80mm 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 locationwe recommend .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.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.*If possible, first attempt to balance the modelby changing the position of the receiver batteryand receiver. If you are unable to obtaingood balance by doing so, then it will be necessaryto add weight to the nose or tail toachieve the proper balance point.CONTROL THROWS. 1) We highly recommend setting up aplane using the control throws listed. 2) The control throws should be measuredat the widest point of each control surface. 3) Check to be sure the control surfacesmove in the correct directions.Ailerons : 12mm up 12mm downElevator : 12mm up 12mm downRudder : 20mm right 20mm leftAileron controlPRE-FLIGHT CHECK.121212122020 1) Completely charge your transmitter andreceiver batteries before your first day of flying. 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 enjoyableflights with yourMIDGET MUSTANG -EP.21
