Building the Green Air Designs DH Mosquito Wings 1. Identify the lower wing skin, wing spar, the ribs R1 R5 and riblet R1a 2. On a flat surface glue the ribs to the spar as shown. Make sure to make a right and a left hand set
3. Line up the fronts of the ribs with the leading edge of the lower wing skin. Glue in place 4. When set pull up the leading edge and glue to underside of ribs. Clamp in place until set. 5. Glue in place the riblet R1a as shown next to R2
6. Identify the 3mm and 6mm aileron parts 7. The 3mm parts are the lower ones. Sand the front edges of the ailerons at an angle so that when they are joined they are able to move freely
8. Glue hinges in place on lower 3mm surface. Make sure they are not in line with any of the ribs in the wing 9. Glue in place the upper part of the ailerons.
10. Using wire provided make up the aileron torque rods. Glue them in position as shown and at the same time glue the hinges to the lower wing skin. Remember to put a small loop in the torque rods on the inboard side to allow attachment of the control rods to the torque rods.
11. Now join the two lower wing panels together. The spars are cut to provide for the correct dihedral angle. Just prop up one wingtip so that the spar joins correctly 12. Once set install the wiring for the motors and speed controllers as necessary
13. The next step is to add the upper wing panels. Do this one at a time. Ensure that the wing you are working on is on a flat surface and that the other wing is supported under the tip to maintain the dihedral. Hold the skin in place with tape or weights until set. Once dry repeat for the other wing. 14. The basic wing structure is now complete. Sand the ailerons so they follow the contour of the wing. Turn the wing over and sand away the outer trailing edge to provide some washout - see diagram? 15. The picture above clearly shows the placement of the aileron servo. Use some of the tubing provided to make a small bush between the control rods and the torque rods. Ensure there is no metal to metal contact. Adjust the control rods and the servo now to ensure full range of movement as once finished, no adjustments can be made. 16. Next identify the nacelle sides and parts NB1 and NB2
17. glue the sides to NB2 as shown 18. Then add NB1 19. Chamfer the inner rear of the nacelle sides so they fit together comfortably
20. When happy glue together and hold in place until dry 21. Identify the lower nacelle parts 22. Glue in place as shown. If necessary use a scrap piece of wood to hold the sides apart so they follow the line of the bottom part.
23. Sand the nacelle structures to a smooth shape 24. Once happy the nacelles can be glued to the underside of the wing as shown. Once dry you can install your motors and speed controllers. If using brushless motors make sure the direction of rotation is correct before proceeding any further. 25. Identify the parts NT1, NT2, and NT3
26. Glue NT1 in place as shown 27. Sand the rear part of NT2 so it a snug fit against the upper wing skin. Glue in place as shown
28. Then add NT3 29. Identify the two nacelle rings 30. Glue in place as shown 31. Use some scrap 6mm depron to form the leading edge outboard of the nacelle
32. The whole wing/nacelle assembly can now be sanded to shape 33. Mount the Motor mounts up into the top surface of the nacelles to make sure that you get the motor Central in the nacelle Fuselage 1. Identify the two fuselage sides and the two formers
2. Glue the formers to one of the sides making sure that they are at 90 degrees 3. Add the other side 4. Apply glue to the upper part of the rear former and pull the sides together. Hold in place until set.
5. Identify the parts FB1, FB2, FB3 6. Glue FB3 to the parallel sides of the fuselage making sure that it is positioned such that then the nose parts are pulled together FB3 is inline with the front of the fuselage sides 7. When set pull the nose together and glue in place
8. Once this is dry pull the rear fuselage sides together and glue in place 9. Once set add the parts FB2 and FB1 as shown. The aim is to produce a laminated shape which can then be sanded smooth to produce the rounded shape of the full size aircraft 10. The lower part of the aircraft can now be sanded to shape
11. Identify the tail plane and elevators 12. Sand them to shape and remember to sand the front edge of the elevators to allow them to move freely when hinged. 13. Glue the wire in place when you are happy with the elevator movement. 14. Attach the elevators using the hinge material provided. 15. Glue the tail plane in place in the fuselage ensuring it is square
Fit the elevator servo just behind the former as above. Fit the control rod now and adjust with the elevator servo neutral as no adjustments can be made after the next step. Ensure that you have adequate movement before commencing to part 16. 16. Identify the parts FT1, FT2, and FT3 17. Glue in place FT1. You may find the thin material above the wing has bowed outwards. If this is the case glue the front and rear sections first. Then, once set apply some glue to the wing section and hold in place until set.
18. Next add FT2 19. Followed by FT3 19. The fuselage can now be sanded to shape looking from the front of the aircraft you are looking for an almost egg-like cross section
Final assembly 1. Carefully cut out the top section of the fuselage above the wing 2. Place the wing onto the fuselage. Make sure its is a good fit and is square with respect to the fuselage and the tail plane. Once happy glue in place.
3. Trial fit the top fuselage section. Adjust as necessary then glue in place 4. Identify the vertical stabilizer 5. Sand to shape and glue in place
6. Sand the nosecone roughly to shape then glue in place. Once set shape it into the rest of the fuselage. 7. Finally fit the canopy. You may wish to leave this until after the model is painted. Cut a hatch under the wing for access to the Rx and for the placement of the batteries in the nose. FINISHING UP. C`o`G is 50mm from the leading edge. Control movement Elevator Rates +- 10mm Aileron +- 12mm Once flown, cover with a layer of light weight filler, rub down smooth and seal with a PVA / water mix. Leave this to dry and then sand. Repeat this until you have the surface finish required. You are now ready for paint. Do a paint test on some scrap depron to ensure no damage will occur resulting from using the wrong paint. We recommend acrylics but you can use some enamels, if careful. (No responsibility will be taken for incorrect use or paints or glues as some can melt the depron).
