Wing

Wing centre section

Epoxy together the wing central ribs W3 and W4; insert the 3mm beech dowels into the holes to obtain the correct match.
Note: Make a left and right pair of ribs. (Fig. 20)
Epoxy the W10 wing fixing bolt plate between the central ribs. (Fig. 21)
Epoxy together the parts of the W13 main spar shear webbing; the short 0.8 mm ply W11 joiner (with a hole in the centre) to the front side, the W12 long joiner to the rear side. (Fig. 22) (Fig. 23)
Make bays for P32 wing carbon joiners; epoxy together the W14 front (shorter) 0.8 mm ply plate, 5 mm ply central plate W15 and rear 0.8 mm ply (longer, slanted edge) W16 plate. Prevent the epoxy hardening inside the bays – put the parts together with the P32 carbon joiner inserted, then immediately remove the joiner (do not forget to clean the joiner using paper tissue and rubbing alcohol before the glue sets). (Fig. 24)
Slide all ribs onto the mains spar shear webbing (no glue yet!). Bind the joiner bays with the provided Kevlar thread and soak with medium CA. (Fig. 25) (Fig. 26)
Insert the W27 rear spar, trial fit the W30 leading and W17 trailing edges. Sand to fit if necessary. Once satisfied with the fit, glue all the parts of the wing centre section with medium cyano over the building plan protected with a sheet of thin clear plastic film (you might find better glueing ribs to the W13 main spar shear webbing with an aliphatic resin).
Edge glue together the W24 upper D-box sheeting (1.5 mm balsa) and the W26 upper 8×2 mm spruce stick main spar; once cured glue it to the wing using aliphatic resin. Use a hardwood stick positioned along the leading edge to push the balsa sheeting straight and even to the W30 leading edge.
Glue the W26 lower 8×2 mm spruce stick main spar in place.
Bevel both two R5 end ribs of the wing centre section using the supplied 7° dihedral jig. Then glue the W6 3 mm Lite Ply end ribs. You might find it easier doing it later; with the P32 joiners inserted and finished wing outer panels attached.
Glue the W21 airbrake frame to the upper side of the wing; insert and glue the airbrake bay reinforcement plate W20 (balsa 1.5 mm) into W5, W7 and W8 ribs. Cyano the W34 fibreglass bushings for the airbrake torsion bar onto W3/W4 and W7 ribs. Insert the 3 mm carbon torsion bar W37 into the bushings. Do not forget to slide the W36 control horn in the centre. Do not glue yet! The control horn and airbrake levers are to be glued in place once the wing is covered and the servo and airbrakes fitter (refer to Det. C).
Glue the W29 magnet holders to the bottom side of W21 airbrake frames. The pairs of W33 magnets will be epoxied into the holders W29 and airbrakes W22 and W23 only after the wing is covered.
Glue the 1.5 mm balsa W28 upper centre sheeting (supplied in 2 pieces) and the bottom W19 sheeting in place over the W3 ribs.
Do not glue the W25 airbrake servo hatch; it will remain removable for easy access to the servo. You can secure it using e.g. small wood screw (not supplied in the kit) to the 5 mm plywood holders W32. Do not forget to cut the opening for the wing fixing bolt into the balsa sheeting.
Epoxy the W1 central riblet with the wing alignment pin sandwiched between two W2 riblets in place. Glue the 1.5 mm front bottom sheeting W18 between the W3/W4 ribs.
Sand to fit and glue the 2.5 mm balsa gussets W38 in place. (Fig. 27–31)
Fine sand the entire wing centre section (incl. the airbrake).
