FLY Construction guide
FLY is a competition model of F1H category. Generally, all structures of your FLY are built directly over the full size plan. To ensure they
do not stick to the plan either cover with plastic wrap or rub a wax candle over the areas where frame members meet.
Balsa cement or cyanoacrylate glue can be used for the majority of the balsa structure.
The following tools and materials will help in building:
1) A fiat, soft wood board about 1'x 2'and about 1/2" thick.
2) Straight pins.
3) Plastic food wrap or wax candle.
4) Pliers, preferably long nose type.
5) A single edged razor blade or model knife.
6) A ruler.
7) A soft bristle brush about 1/4" wide.
8) Sandpaper, 200 grit or finer.
9) Balsa cement, or cyanoacrylate glue.
10) Clear cellu lose dope.
11) White paint.
12) Cellulose thinner for brush cleaning.
13) Scissors.
14) Tissue paste.
GETTING STARTED
Tape the plan to your building board. Before starting construction, familiarise yourself with the various components in the kit. Vou may
wish to run through the instructions and mark the balsa parts with their appropriate numbers.
CHECKING, ADJUSTING AND TRIMMING
Vou have taken a lot of time and effort to build your model, do not rush the last and most important part, adjusting and trimming before
flying.
Firstly, hold the model facing you and ensure that the wings are fiat along the bottom and not twisted or warped, also that the fin and
elevator are straight and level. If any surface has been warped during construction, gentle application of heat with a hair dryer or heater
will facilitate removal, it may be an idea to unglue the wing struts first jf a large error has crept in reglueing after correction.
Balance
The centre of gravity of the model is shown on the plan, hold the model about one third of the way back from the forward edge of the
wing, supporting it on your fingertips the model should be level, if the tail drops add lead shots to the nose. Add only enough weight to
bring the modellevel.
Test flying
Choose a calm day and if possible an area with long grass. Always launch the model into the wind. First check the glide, hold the model
as near the balance point as possible and launch firmly forward aimíng about 20 feet in front of you. Do not adjust until you have made
several attempts to ensure that you need adjustment. If the model stalls, that is, the nose rises up and the model falls to the ground, add
lead shots to the head. If the nose falls quickly and the model dives into ground, take out lead shots.
1. Glue head 1 and spruces 2 as shown.Cut openjngs in formers 3, copy and drill the holes for wires 41 and 42 according the holes in
head. Glue formers 3 in place. When dry, sand them around.
2. Between the ends of spruces 2 glue former 9. Glue in place balsa sheets 4. Glue the tow hook 14 into the hole on the bottom of the
fuselage. Do it exactly like shown on the drawing. Glue the pieces of 1,5 balsa into the rest of hole. For using a mechanical timer
prepare the predrilled holes for its installation. Do the same for using the tow hook for whirling tow.
3. Sand to shape control horn 12 as shown. Sand to shape leading edge of vertical fin 10. Send rudder 11 to the shape as shown. Cut
into rud der 11 opening for the control horn 12. Glue control horn in place as shown. Cut opening into vertical fin 10 for al band 13. Put AI
band 13 into place, fold as shown and glue using CA glue.
4. Make the tubes 39 and 40 for the piano wires from the strip of covering paper. Wind the strip of covering paper 80 x 100 mm round
the wire of 3 mm. Ouring winding add the glue. After winding move of the wire in the tube several times in order not to glue together.
After approx.15 min you can take out the tube from the wire. Make the same way the tube for the wire of 2 mm from the strip of paper 30
x 70 mm. Make 3 pcs of both dimensi on.
5, Pass the piano wires 41 and 42 include tubes 39 and 40 through the holes in the fuselage. Put on them the ribs 5 from both sides and
glue them with 5 min epoxy to the fuselage. Check the right position of the wires to the side of the fuselage. When dry cut out the
overlapped ends of tubes.
6, ln the rear side of the fuselage cut holes on the top for vertical fin 10 and from the bottom for the part 8 and glue them in place as
shown. Glue on place plywood formers 6 and 7. Join both parts 10 and 11 with strip of self adhesive tape 55. The complete vertical fin
10 and tail edge 8 glue to the fuselage. Check the position of wires 41 and 42, vertical fin 10 and part 6.
7. Glue part 17 on the part 16 as shown.

8. Selecl a strip of performed trailing edge 36 and cut the notches for the ribs. Do the same way the notches into the trailing edge 49.
9. On the building plan covered with polyethylene foil assemble the middle part of the wing. Put under spruce 16, 18 and front part of
trailing edge pieces of balsa as shown on the drawing and pin to the plan. Glue all ribs 20,21,22 and 23 in position on spar and trailing
end notches. Glue and pin into place leading edge 34 and ledges 16 and 18 into notches of the ribs. After dry ta ke aut the part of wing
from the board. The wing tips glue the same way. The ribs 23 are glued in the place of break in the middle and on the wing tips with
obliqueness. The slant 7 grades Vou will assure by using former 61 which Vou are able to make according drawing from part of plywood
ar hard paper.
10. After cut off the overhanged ledges, leading and trailing edges, sand the wing tips as shown. Glue the rib 5 to the wing and drill the
holes for the tubes 39 and 40. The wires 41 and 42 put through the holes in head. Put tubes 39 and 40 on them and put the both part of
wings on the tubes 39 and 40 and check their position, angle must be same on the both sides. Glue on the several points the tubes in
the right position with CA glue to the ribs and spruces of the wing. Than glue the former 43 between the ribs and spruces of the wing.
Fill in the space between the former 43 and gloves of the wires 39 carefully with epoxy. The short tubes 40 glue with epoxy to spruce
18. Glue balsa 1,5 mm 37 between ribs 20 as shown. The space between the spruces 16 fill in and glue with spruces 44 made from
balsa 2 mm.
11. In the ribs 23 make the holes for dihedral brace 32. Check the fit of dihedral brace into each wing half. It should slide smoothly in
until the center is reached. Test assemble the wing to assure that the fit of the brace allows the wing root edges to meet perfectiy.
Leading edges and trailing edges should meet exactly. Use sandpaper to eliminate any binding ar to correct alignmenl. Smear slow
setting (30 minute) epoxy on half of dihedral brace and slide it into one half. Coat the wing center faces with a very thin layer of epoxy
and coat the other half of the wing brace. Slide the wing halves together until they meet and fit. Se sure that the dihedral brace stays
centered. When dry sand the whole wing including the wing tips to shape as shown.
12. Glue the horizontal stabilizer by the same way like wing. When dry sand the horizontal stabilizer to shape as shown. Orill the slant
hole of 2 mm for pin 51 in the middle rib 47 as shown. The pin glue with CA glue after covering and painting the horizontal stabilizer.
13. Sand smooth the entire struclure to eliminate all rough edges and bumps. The laminates tail surrounds will need carrying with a
knife to bring them down to the correct profile. The trailing edges should be sanded down to a near point and the leading edges
rounded (similar to the wing section). Sand off the edges where the two surfaces hinge together. Give 2 coats of dope, sanding
between each coat to seal the grain. In general, the grain of the tissue should run lengthwise on the piece being covered. Start by
covering the top and bottom of both wings, sticking the tissue to the edge of the structure only and gently pulling aut the wrinkles as
Vou go. Take care not to warp the wings when pulling the tissue as any warps can be difficult to remove and will seriously affecl the
flying ability of your model. Shrink the tissue by spraying with water, This can be done with an atomiser ar toothbrush. Sprav one
wing at a time, pinning it down to the building board as it dries. This prevents warps from creeping into the structure. When dry, give
the wings a coat of clear dope.
14. Sand smooth the fuselage and give him a couple of coats of dope, sanding between each coat to seal the grain. The front part of
fuselage as far as the fuselage spruce Vou can paint with colour dopes. In place where the fuse is placed glue the strip of aluminium foil
62 with 5 min. epoxy in order not to be burn up.
15. When dry lay the wing centre down on a fiat surface, one panel at a time. The panel should lay perfectiy fial. After that make the
negatives on the both tip trailing edges. The ends Vou wrench carefully above the cooking stave and twist to correct position and cool.
Check the negative on the fiat board. The wing tip panel put on the fiat board, both tip trailing edges must be high up 3 mm. Similarly,
look for twists ar curves in the stabilizer and make it perfectly straighl.
16. On the right side of horn 12 fix the rubber ring 58. Next end is fixed with the notches 19. The vertical fin 11 is moved to the right side.
The movement Vou can change by AI band 13. On the opposite side of horn 12 is hanged the pushrod 57 which moving the vertical fin
while trailing into the neutral.
17. The pushrod 59 hald the horizontal stabilizer in flying position. After the burning
af rubber ring 58 the horizontal stabilizer will move
approx. of 45 grades. The movement is done by distance X between 1 mm long tube 60 and tube 59.
18. The pus hrad 57 is hald on tow hook 14 as shown. After finish of towing the pushrod 57 is free and rudder 11 move to the right side.
19. The centre of gravity is shown on the plan. Add only enough weight to bring the modellevel.
20. Test flying. Chaose a calm dav and if possible an area with long grass. Always launch the model into the wind. Hald the model as
near the balance point as possible and launch firmly forward aiming about 20 feet in front of Vou. If the model stalls, that is, the nose
rises up and the model falls to the ground, add weight to the head. If the nose falls quickly and the model dives into ground, take aut
weighl.
21. Take offwith pushrod is shown on drawing
