Page 6: Fin And Rudder
Building Instructions FIN AND RUDDER Take the three parts that form the fin (Parts 6, 7 and 11), trial fit before gluing together. The bottom of the fin will be trimmed down later to match the rudder height in final assembly. Remove the four pre-cut parts (Parts 10, 12, 13 and 14) of the rudder from the cutting sheets;... - Page 7 With the supplied strip of 9mm (3/8”) x 6mm (1/4”) cut to length to form the eight centre rails, glue in place with white wood glue. Take the eight pre-cut parts (Parts 16(2), 17(2), 20(20), 21(2)) which form the elevators, trial fit, ensure the tips are at 90°...
- Page 8 Do not glue the hinges or coupler in at this stage. Sand all parts to a smooth finish and round off the leading edge of the tail plane ready for covering. FUSELAGE At this point the decision needs to be made whether the glow or electric version is being made. If the glow version is your choice then the balsa nose section and ply doubler need to be cut as shown below.
- Page 9 Add the second fuselage side, lining the Formers up with the cut outs. Use a set square to check that the fuselage sides are parallel on all sides, make minor adjustments if necessary. Make time to get this right, if the sides are not parallel the model will be out of square. With a scrap piece of 6mm (1/4”) balsa sheet, cut a 6mm (1/4”) post for the rear section of the fuselage.
- Page 10 the fin slot). With a razor plane and sandpaper, shape the backbone to these guide lines as shown in the picture on the right of the next page. Place the backbone with the front sloping edge on F3 and gradually sand the rear section until it touches F4 as shown in the diagram below.
- Page 11 Add some scrap balsa to the area between F1 and F2 to give a greater gluing area as shown in the right hand picture below. Glue the main undercarriage plates together (Parts 29 and 30) before gluing to the bottom of the fuselage with epoxy. Glue the undercarriage plate in place followed the bottom deck (Part 25).
- Page 12 Place the washers provided on top of the magnets and push the remaining top deck down onto them to leave an imprint in the underside of the balsa, carefully carve this area to allow the washer to sit flush with the surface and maintain contact with the magnets.
- Page 13 With a hammer, carefully knock the captive nuts into the wing mounting plate (Part 32), making sure the nuts are square to the plate so that the bolts will engage squarely when inserted through the wing. Glue the plate in the notch on the wing doubler plates at the predefined angle. Finally sand the fuselage to a smooth finish, rounding off the back bone, front top and bottom deck.
- Page 14 Use a slow setting glue for the next few stages to give you time to align the wing. Read this section carefully first before attempting to glue (please ignore the ribs shown in the photos, these were from an earlier version.
- Page 15 Check all the ribs are at 90° to the main spar and leave to dry. Undertaking the above in one step will ensure that the wing is true and warp free, just make sure you have enough drying time to complete the process.
- Page 16 Repeat this with the TE 1220mm (48”) x 25mm (1”) x 1.5mm (1/16”) sheet. Using the supplied sheet of 915mm (36”) x 100mm (4”) x 1.5mm (1/16”) balsa sheet the centre section (across the 4 centre ribs). The remaining sheet will be used for the underside centre sheeting. Un-pin the wing from the board and turn over, re-pin making sure that the TE is straight with a straight edge.
- Page 17 With the wing upside down on the bench mark the centre line on the TE, measure 25mm and draw a line parallel with the TE. Mark the centre line on the wing bolt support (Part 38) and glue in position. With a drill held at 90 to the wing surface carefully drill a hole through the plate and through the wing for the wing bolts.
- Page 18 edge. Ensure that you get at least 45° free movement either way. Do not glue the hinges in at this stage! Sand all parts to a smooth finish and round off the leading edge of the fin ready for covering. COVERING Before covering seat the wing, tail plane and fin and make sure that they all fit.

Page 19: Final Assembly
Once the fuselage has been covered, line the undercarriage up with the centre of the two mounting plates. Attach the undercarriage, ensuring it is square to the fuselage with the screws provided through the pre- drilled holes. Make sure the axles are at 90° to the centreline of the fuselage. Minor adjustments can be made with pliers or mole grips, just ensure that you hold the undercarriage legs and not the fuselage when doing this to prevent damaging the fuselage. - Page 20 Insert the tail plane into its slot and check the measurement B1 = B2. Once satisfied that the tail plane is square, mark with a pencil both top and bottom along the edge of the fuselage. Remove the tail plane from its slot and carefully cut 1/16”...
- Page 21 Insert epoxy into the hole in the elevators made for the wire joiner. Push the joiner through the fuselage into the hole behind the tail plane and insert the elevators on to the joiner while inserting the hinges into their slots.
- Page 22 tube through F1 and cut to length to allow the servo full movement when the inner steel cable and clevis are fitted. Place one of the supplied clevises on the end of the Bowden cable. Pass it through the outer tube from the engine into the radio bay and clip it onto the engine throttle horn.
