Fuselage Assembly

Start by laying out and checking the abovecontent list.Insert the 2 inlet ducting tube intothe fuselage. Please note that there is a rightside and left side. The dents in the inlet tubesides faces the bottom.

2 ) Slide the ducting into thefuselage from the open canopy.Do both sides. Sliding in theducting.

1 ) Left side ducting.

Page 5: TF 70mm BAe Hawk

3 ) Push the ducting to the outside until it sits snug with the inside ofthe intake lip of the fuselage. Do this step as dry fitting only DO NOTGLUE YET !

4 ) The rear of the 2 ducting should meet at the back. Turn over thefuselage and check from the lower hatch.We recommend that you dry fityour EDF unit into the wood fan bearer along with the ducting at thistime. If the ducting is too long for your fan unit, you can trim the lengthof the ducting for your particular fan unit.

5 ) Once the ducting length is correct, mark the oultine of the spinner ofyour fan onto the 2 ducts and trim to fit.

6 ) The rear ducting shouldmeet as in photo, if not thenyou need to switch the ductsuntil they do.Use a few drop ofglue to secure the ductassembly to the wood former.

Page 6: TF 70mm BAe Hawk

11 ) Glue a piece ofreinforcement on the insidejoint for a better air seal.

7 )Mark the outline of the fanunit spinner for trimming. Doboth ducts.

8 ) Once you have the ducting all correctly set out start by gluing the 2ducts at their ends and then glue the front intake ends to the inside ofthe fuselage inlet. Use clamps for a secure joint.

9 ) The front should look likethis after gluing.

10 ) For a better air seal, we recommend gluing a piece of plastic sheetor a sheet of balsa on the inside joint of the duct.

Page 7: TF 70mm BAe Hawk

2 ) Locate the fix landing gearwire legs and bearers. Insertthe landing gear wire into thebearer. Note that there is a leftand right landing gear bearer.

3 ) Lay the landing gear bearerwith wire next to the winglanding gear cutout. Make surethat the outlines match thendry fit it in. Once it sits correctand flush, proceed to glue thegear bearer with Epoxy into thewing.

Wing AssemblyLayout both wings and turn them bottom up.Locate the 2 precut holes for the aileron servo andlanding gear bearer.

1 ) Use light pressure to locatethe bottom holes. Cut thecovering away using a sharphobby knife.

Page 8: TF 70mm BAe Hawk

6 ) Locate the 2 aileron servo covers and trim the cover away at the cutout for the servo horn. Again, note that there is a left and right side.Dryfit the servo covers until correct and flush.The servo horn hole shouldbe on the outside of the wing.

4 ) The wings comes with supplied CA hinges. They are not glued inthough. Push the aileron butt up against the wng and apply a few dropsof thin CA at the location of the hinges.

5 ) Apply a few drops of thin CAat the hinge locations

Page 9: TF 70mm BAe Hawk

7 ) Run servo extension wires through the wings into the fuselage.Connect the servo to the extension wires and secure with a piecec oftape. Connect up the servos to the receiver and turn on the radio andreceiver.Centre the servos on both sides. Now glue both servos to theexposed bottom of the aileron servo covers.The servo horn should becentered in the hole. Move the aileron stick and make sure that there isno servo horn binding.

8 ) Screw the aileron servo cover with servo onto the wing at the 4corners.Connect up the push rod and use that to mark where to glue theaileron horn. Drilla hole where the aileron goes and glue with Epoxy.

Page 10: TF 70mm BAe Hawk

11 ) Push the 2 wings onto the spar and butt up against the sides of thefuselage. After dry fitting and checking fit, you can now glue the wingsto the fuselage. Do not forget to pull the aileron servo extension wirethrough the fuselage. When gluing make sure that each wing is flushagainst the top and bottom of the wing stub on the fuselage sides. Westrongly recommend the use of 30 min or longer epoxy to glue thewings. This will allow time for fine adjustments before the glue dries.

9 ) Connect up the push rod tothe aileron horn and turn onyour radio to make sure thatthe controls and the aileronsare centered. Adjust thepushrod length or use radiosubtrim function to achievethis.

10 ) Locate the 2 carbon sparsand thread it through thefuselage. The spars shouldstick out on both sides of thefuselage. The Spars sits at thebottom of the fuselage.

Elevator Assembly

1 ) Push the 2 plastic pus rod outer sleeves from the rear towards thefront,passing through the locating .holes in the wood formers Glue thesleeves to the inside of the fuselage and at the formers with a few dropsof epoxy.

2 ) Slide the horizontal stab into the precut slot at the rear of thefuselage.Note that the sleeves sits below the stab. DO NOT GLUE YET !

Page 12: TF 70mm BAe Hawk

3 ) Slide the push rod into the sleeve and connect up the clevis. Locatethe elevator lever and connect it up to the clevis. Push the elevator leverinto the rear and out the sides at the rear of the stab. If the slot is tootight use a file to trim the elevator slot longer or bigger.

Page 13: TF 70mm BAe Hawk

5 ) Now cut the elevator push rod sleeve to length at the rear allowingfor enough down elevator travel and use a drop of glue to secure thesleeve to the bottom of the horizontal stab. Secure the sleeve to thebottom of the horizontal stab.

4 ) After dry fitting the elevator onto the elevator lever, now glue theelevator lever end into the elevator,and use thin CA to glue the elevatorhinges. Once the elevators are done, take care to centre the horizontalstab and glue to the fuselage using epoxy. We recommend using stripsof balsa or wood as fillet at the joints for reinforcement.

Battery Tray Assembly

2 )Slide the battery tray intothe fuselage, noting directionof the tray. The 3 tonguesslides into corresponding holesin the former in the front. Gluethe trasy with epoxy.

6 )The front of the sleeve should sit on top off each inlet duct. Securethe sleeve to the top of each duct using epoxy.

1 )Locate the battery tray, andglue the vertical former to thebottom of the tray.

Page 15: TF 70mm BAe Hawk

3 )Mount the elevator servo onto the battery tray at the rear. Nowmeasure the correct pushrod length and cut to length. Remember toalso cut the plastic sleeve correspondingly. Hook up the push rods tothe servo using the supplied stopper. Adjust the elevators halves untilboth sides are neutral.

Landing Gear Assembly

1 )Now glue the main gear wire into the slot in the gear bearer and use2 plastic straps with screws to hold the gear wire secure.

Canopy wood base.

2 )Glue the front gear bearerinto the front former tray on theinside of the fuselage. Thenuse 4 screws to further securethe bearer.

3 )Now insatll the suppliedsteering arm onto the frontgear wire. Use the suppliedwire to make a control loop.

Canopy Assembly

1 )Locate the canopy wood base. Use canopy glue or silicone to gluethe wood base to the inside of the canopy.

Page 17: TF 70mm BAe Hawk

2 )3 photos shows the arrangement of the canopy woodformer base.

Page 18: TF 70mm BAe Hawk

3 )Optional included is a canopy hatch for fixing the canopy to thefuselage. Use the following photo for reference on the installation.

1 )2 Long tie straps are supplied. Thread them through the precutholes in the fan cradle.Place the fan unit in the cradle and line it up withthe inlet ducting, at the same time make sure that the alignment of thefan is also straight along the centre line of the fuselage.

2 )Use the supplied 20 X 30clear plastic sheet and roll athrust tube for the duct fanunit. The exit diameter of thethrust tube should be about 63-64 mm.Slip the thrust onto therear of the fan unit and attachwith clear tape. Either tape orscrew on the lower fan unitcover.

Before the first flight please check the following :

1. All the flying surfaces are straight and true.

2. The CENTRE OF GRAVITY is at the recommended location.

3. The aileron and elevator travel are as recommended.

Travel AdjustmentsAileron travel Up 7 mm

Down 5 mm

Elevator travel Up 6 mm

Down 6 mm

Note
According to guys on RCgroups, start at 65mm - 85mm makes for a tail heavy plane.....
