<languages/> <div lang="en" dir="ltr" class="mw-content-ltr"> == Introduction == The F1H glider TARA is a great entry-level kit for any modeller who has already gained some skills in classic balsa bashing and dope and tissue covering. You will need some basic modeller‘s tools, glues and dopes – you will find these handy with any of your future projects as well. Please make yourself familiar with the building plans and this manual BEFORE you actually start the assembly. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === Before you start === '''Glue:''' You can use acetone-based modeller's glue (UHU® Hart etc.), water-resistant white glue ([https://www.kavanrc.com/category/dispersion-485 KAVAN White Glue], BISON® Super Wood etc.) or medium cyano ([https://www.kavanrc.com/item/kavan-power-ca-20g-medium-en-152585 KAV56.9952]). </div> <div lang="en" dir="ltr" class="mw-content-ltr"> '''Dope:''' [https://www.kavanrc.com/en/category/dopes-891 KAVAN STANDARD line] Adhesive dope, Shrinking dope, Top gloss dope and Thinner are the must for the dope and tissue covering, indeed. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> '''Tools and accessories:''' You will need a perfectly flat building board (at least 300×700 mm), modeller‘s knife ([https://www.kavanrc.com/item/kavan-knife-with-cutting-mat-156305 KAV66.770]), jigsaw, sanding blocks with 180 and 360–400 grit sandpaper, model hobby pins, scissors, sharp model hobby knife, flat and round fine file, soft flat (1/4"–3/8") brush, thin clear plastic film to protect the building plan (a large PE bag cut in half will work). </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === Precautions === The model you build and fly is not a toy! Although it may seem light and slow in flight, it is capable of causing injury or other damage if mistreated. It is up to you whether you build the model properly, fly properly and continue to fly in accordance with common practice and rules (and common sense). If you are just getting started with aircraft models, ask for advice from your model shop or an experienced modeller at your local modelling club to find a good instructor. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> '''Before construction:''' Build the model exactly as instructed. Do not change or modify the model. If you do, you risk that the model may be unsafe or unable to fly. Take the time to build everything firmly and reliably. Use appropriate tools, accessories and other equipment that is in top condition. Correctly install all parts of the model and check the model before the first and every subsequent flight. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> {{Note|type=info|'''Note:''' We, as a kit manufacturer, can guarantee you a premium quality kit with detailed instructions, but flight characteristics and performance depend entirely on how you complete the model. Since we have no control over how you complete and operate the model, we cannot (and cannot be assumed) assume any responsibility for any damage caused or related to the operation of your completed model.}} </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === Specification === {| class="wikitable" |+ |Wingspan |1100 mm |- |Length |828 mm |- |All-up weight |225 g (min 220 g) |} </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === Assembly === </div> <div lang="en" dir="ltr" class="mw-content-ltr"> * Lay the wing building plan on the building board and put a sheet of a thin clear plastic film to protect the building plan. If you have just a small building board, you can carefully cut the building plan into sections – wing section, horizontal tailplane section etc. * Before you apply the glue, please, always double-check the correct size, shape and alignment of the particular part. * Balsa and spruce sticks are intentionally supplied oversized in the kit. Pin the stick to the plan overlapping at both ends – you will cut/sand them to the correct length/shape once the assembly of the particular part has been finished. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> ==== Wing ==== There is the wing centre section and both two wing outer panels drawn on the building plan. If you want to, you can assemble them simultaneously. Pin the left half of the tapered balsa trailing edge '''3a''' to the building plan. Carefully match the pre-cut notches with the ribs drawn on the plan. Attach the other half of the trailing edge '''3b''' to the '''3a''' and check whether the notches are matching. If yes, glue the '''3b''' to the '''3a''' and pin down to the plan. If the notches do not match, trim the trailing edge '''3b''' as necessary to fit. Lightly sand the CNC milled balsa ribs '''1 (Det. G–G)''' to remove any imperfections. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Pin down the pre-shaped balsa leading edge '''2'''. Glue the balsa ribs '''1''' in place. Fit, cut to size and glue the bottom 1.5 mm balsa sheeting '''4''' between the leading and trailing edge. Glue two ribs '''6''' insets about 2 mm along the outer edge of the central sheeting and another one in the centre of the sheeting. Glue the balsa end rib '''5''' in place – the bevelled side outwards (in similar manner to '''Det. F–F'''). </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Glue the wing main spar '''7''' (3×8 mm spruce stick) into the notches in the upper side of ribs (trim the bottom edges slightly to slip easier in). Glue only the bottom of the main spar to ribs '''5'''. Insert partly the wing joiners '''42''' along the sides of the main spar in order to get the correct alignment in the wide notches ('''DO NOT glue the joiners yet!'''). Fit and glue the upper central sheeting '''8''' and '''9''' '''(Det. B–B)''' in place. Apply some additional glue to all joints if necessary and let cure. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once the glue has cured thoroughly, remove the wing centre section from the building plan and sand the leading edge. Trailing edge and main spar flush with the edge of the bevelled outer ribs '''5'''. Sand the leading edge to the shape '''(Det. D–D)'''. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> The wing panels are to be built in the similar manner to the wing centre section. Pin the tapered balsa trailing edges '''40''' to the building plan carefully matching the pre-cut notches with the ribs drawn on the plan. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Lightly sand the CNC milled balsa ribs '''41–46''' to remove any imperfections. Pin down the pre-shaped balsa leading edges '''48'''. Glue the balsa ribs '''41–46''' in place. Bevel the front edge of the ribs in order to match the leading edge '''48''' perfectly. In similar manner, lightly sand the bevelled root ribs '''47''' to match the leading and trailing edges and glue them in place '''(Det. F–F)'''. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Glue the wing panel main spars '''49''' (3×8 mm spruce stick) into the notches in the upper side of ribs. Glue only the bottom of the main spar to ribs '''47'''. Insert partly the wing joiners '''42''' along the sides of the main spar in order to get the correct alignment in the wide notches (DO NOT glue the joiners yet!). Trim the gussets '''51''' as necessary and glue in place. Apply some additional glue to all joints if necessary and let cure. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once the glue has cured thoroughly, remove the wing panels from the building plan and sand the leading edge, trailing edge and main spar flush with the edge of the bevelled outer ribs '''47'''. Glue the wing tips '''50''' in place. Once cured, sand them to the shape. Sand the leading edge to the shape '''(Det. D–D)'''. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Trial fit the wing centre section and wing panels – if attached together, the wing panel dihedral must be '''100 mm''' '''(Det. E)'''. Once satisfied, glue the Plywood wing joiners '''42''' to the wing centre section main spar '''7'''. Apply a generous amount of glue to wing centre section end ribs, wing panel root ribs and wing joiners '''42''' and attach the wing panels to the wing centre section. Lay the wing centre section down on the building board. Secure it with a couple of magazines wrapped in a plastic bag serving as a weight. Align the wing panels so their tips were 100 mm above the building board (you can use a couple of books or a wooden block). Let the glue cure thoroughly. Once cured, carefully sand the joints and the entire wing using sanding blocks with a coarse and then fine sandpaper to smooth any rough areas. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once the dope has cured, sand the entire wing frame with fine sandpaper. The wing is ready to covering now. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> ==== Horizontal tailplane ==== The horizontal tailplane is to be built directly on the plan protected with a clear plastic film in similar manner as the wing. Pin down the spruce trailing edge (3×5×405 mm) '''11''' overlapping on both two ends. Glue the balsa centre plate (3 mm – 30×80 mm) '''13''' to the trailing edge '''11'''. Glue the spruce leading edges (3×5×197 mm) '''10''' to the centre plate and pin them down overlapping on both two ends. Cut to size and glue in place the diagonal ribs '''12''' made of 3×5 mm balsa stick. Start with the outer diagonal ribs first. Then proceed towards the centre of the horizontal tailplane. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Glue the spruce main spar '''14''' (3×5×395 mm) to the top of the horizontal tailplane framework. Fit and glue the front balsa upper plate '''16''' (3 mm – 30×30 mm) and two rear plates (3 mm – 13.5×45 mm) '''17'''. Align the outer edges of the plates '''17''' to match the bottom plate '''13''' leaving about 2.5 mm slot between them to fit the bamboo dowel '''18''' later. Sand the gussets '''15''' to fit and glue them in place. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once the glue has cured thoroughly, remove the horizontal tailplane from the building plan. With a sanding block, shape the tips and centre plates as indicated on the plans '''(Det. A–A)'''. Round the leading and trailing edges and the tips '''(Det. A–A)'''. The horizontal tailplane has been finished for now. Once covered with the tissue, glue the bamboo dowel (Ø2.5×50 mm) '''18''' between the plates '''17''' extending behind the trailing edge by 15 mm. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> ==== Fuselage and fin ==== The fuselage consists of the tail boom made of spruce sticks and balsa blocks and the front fuselage block made of Ceiba Plywood with poplar Plywood side covers offering enough space for the ballast and timer (if you decided to install one). </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Start with the tail boom. Blue it on the building board in order to make the tail boom true and straight. Glue the front balsa block '''20''' to the spruce stick (2×8×600 mm) '''22''' taking care the outer edges of the block matched the edges of the stick.<br>{{Note|type=info|'''Note:''' The rear balsa block '''21''' will be glued to the bevelled side of the front block later.}} Now apply glue to the rear part of the spruce stick '''22''' and block '''20'''. Attach the rear balsa block '''21''' matching the edges of the stick. Glue the other 2×8 mm spruce stick '''23''' to the tail boom. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> If you consider installing a timer (either mechanic or electronic) and dethermalizer, now it is the time to trim the openings in the fuselage block '''24''' as needed. Do not forget to cut an appropriate opening in one of the side covers ('''26''' or '''28''') as well. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Insert the tail boom in the notch in the fuselage block '''24'''. Trim the notch if necessary. Remove the tail boom, apply a generous coat of glue into the notch and insert the tail boom. Glue it on the building board in order to make the fuselage true and straight. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Insert the two beech dowels '''25''' (Ø4×32 mm) into the fuselage – no glue yet. The dowels will help with the correct alignment of the side covers. Apply glue to the left side of the fuselage block. Align and attach the side cover '''26'''. You can lay the fuselage down onto your building board and weigh the cover down to cure. Insert and glue the main ballast '''27''' into the nose opening. Glue the other side cover '''28''' in place. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Glue the reinforcement plate '''30''' into the fin '''29'''. Make the front horizontal tailplane seat. Glue the spruce stick (3×5×25 mm) '''32''' to the Plywood plate (1 mm - 25×15 mm) '''31'''. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Mark the position of the tailplane seat to the fuselage according to the building plan and glue it to the tail boom. Lay the horizontal tailplane down on the seat in order to check the tailplane was square to the fuselage sides (when looking from the nose to the tail) and also square to the longitudinal axis of the fuselage (when looking from above). Glue the rear tailplane seat (balsa 1.5 mm – 8×10 mm) '''33''' to the fuselage. Glue the fin '''29''' to the fuselage. Use the horizontal tailplane as a reference again. The fin has to be square to the horizontal tailplane and exactly in the longitudinal axis of the fuselage. Round the leading and trailing edges of the rudder '''52'''. The brass rudder hinges '''45''' will be installed after dopind and covering of the model. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Now glue the Plywood wing seat plate '''36'''. Keep it centred and square to the side of the fuselage. Glue the beech wing hold-down dowels '''25''' into the fuselage. Mark the position of the holes for the horizontal tailplane hold-down dowels '''34''' and '''35''' (bamboo Ø2.5×25 mm) and glue them in place. Glue the balsa bottom fin '''37''' to the fuselage. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> ==== Doping and tissue covering ==== Lightly sand the entire airframe with the fine sand paper. Before the frames are covered, all EXTERNAL surfaces MUST be primed with the adhesive dope (Diluted at least 1:1 with the thinner. The dope must have the viscosity of water. Never use the dope unthinned!). Use a soft flat brush to apply the dope. When dry, lightly sand all doped surfaces with the fine sandpaper. Apply the second coat and sand lightly again. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Sheets of the Vlies covering tissue are supplied in the kit. You can glue it to the airframe using water thinned white glue or clear dope. Always align the "grain" of the tissue the long way - from tip to tip of the wing or horizontal tailplane. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> '''Horizontal tailplane:''' If you are new to the dope and tissue business, you should start with the horizontal tailplane in order to gain the skills on smaller part of your model featuring no curves. Cut a piece of the tissue 10 mm oversized all around the outline of the horizontal tailplane. Apply the thinned white glue or adhesive dope around the external edges of the lower side of the tailplane and to the diagonal ribs and centre plate. IMMEDIATELY set the tissue in position and smooth the edges with finger tips before it has a chance to dry. Cut the tissue all around the outline of the tailplane leaving it 4–5 mm over size. Bend and glue with thinned white glue or clear dope the overlapping tissue around the entire tailplane. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Cover the upper side of the tailplane in the same manner. Apply thinned white glue/adhesive dope to the trailing and leading edges, main spar, centre plates and tips. Do not apply the glue to the diagonal ribs! </div> <div lang="en" dir="ltr" class="mw-content-ltr"> '''Wing:''' Cut four or six pieces of the tissue 10 mm oversized all around the outline (do not forget the upper sheets have to be wider due to the airfoil camber). A skilled builder could cover the entire bottom side of the wing using just one long strip of tissue. The upper side of the wing centre section and wing panels are to be covered by separate strips. Again, start with the bottom side of the win. Apply the glue/dope to the leading and trailing edges and all ribs. Attach the tissue and smooth the edges with finger tips. Cut the tissue all around the outline of the wing leaving it 4–5 mm over size. Bend and glue with thinned white glue or adhesive dope the overlapping tissue around edges of the entire wing. You will have to cut the tissue against the wing panels joints and in short 4–8 mm portions around the wing tip in order to follow the curve of the tip. Cover the upper side of the wing centre section in the same manner (the tissue overlapping over the wing panel root ribs '''47'''). Apply thinned white glue/adhesive dope to the trailing and leading edges, main spar and ribs. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Cover the wing panels with separate strips of tissue. Attach the tissue to the rib, using a pencil and steel ruler or a piece of flexible plastic draw the line marking the joint of '''5''' and '''47''' ribs on the tissue. Trim the tissue to the line and glue in place in the usual manner. You will have to cut the tissue in short 4-8 mm portions around the wing tip in order to follow the curve of the tip. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> You can cover the tail boom as well (apply 4 slightly overlapping strips to the bottom both sides and finally to the top of the boom) to add some extra strength. There is no need to cover the nose. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Now you can apply several coats of thinned shrinking dope in order to shrink the tissue and protect it from moisture. Once the tissue is nice and smooth without wrinkles (after 1–2 coats) you can apply the colour tissue trim and continue in applying the shrinking dope. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Only apply the dope in a dry and well ventilated area at room temperature (over 20 °C – low temperature/high humidity may cause "fogging" of some dopes turning them milky white instead of clear – if that happens you can usually cure it by taking the model to a dry and warm place and applying just the fresh thinner with a brush to the „fogged“ part). Apply 3 to 5 coats of thinned dope to the entire model. Use the top gloss dope for the fuselage and the last coat for the wing and horizontal tailplane. Lightly sand all doped surfaces with fine sandpaper between each coat. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Apply the colour tissue trim to the fuselage before the last coat of dope. Use the top gloss dope for the final coat. '''The stickers are to be applied only after the final coat!''' </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Let the model dry thoroughly after each coat for 2–3 days. Check for any warping of the wing or horizontal tailplane. If that happens, you have to lay the wing and/or tailplane down to a flat surface protected with a plastic film and weigh it down (a couple of magazines in a plastic bag to the rescue again) after each coat. Let it dry thoroughly. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> ==== Final assembly, Centre of Gravity (CG) ==== Secure the side towhook '''39''' to the left side of the fuselage using two screws '''38''' – refer to the building plan. The towhook is adjustable. You can move it forward on a windy day or backward on a calm day in order to achieve nice and steady climbing during the hi-start. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Use the tip of a pointy modeller's knife to cut slots for the brass tin rudder hinges '''53''' into the fin '''29''' and rudder '''52'''. Cyano the hinges into the rudder and then into the fin leaving a slight gap between the fin and rudder. Tie the wing and horizontal tailplane to the dowels on the fuselage using several loops of the supplied rubber thread.<br>{{Note|type=warn|'''Important:''' One loop is never enough!}} </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Drill 5 mm access hole into the additional ballast compartment in the fuselage (refer to the building plan). Support the wing of the model with your fingertips in the centre of gravity position (the point marked by an arrow on the fuselage plan). The fuselage should be level. If the nose pitches up, put in as much of additional ballast (not supplied in the kit) as necessary. You can use pellets, small screws etc. Once satisfied, cover the hole with a strip of clear sticky tape. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> The correct balancing is essential. Incorrectly balanced model will be difficult to set up or unable to fly at all! </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === Flying === Once again check the correct position of the centre of gravity, check for any excessive warping of the wing, tailplane and fuselage. Choose a nice calm day for the first flight. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> The model must be launched into the wind every time. Throw grass into the air to observe the wind direction. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Hold your model with the wing and fuselage level. Launch your model with a gentle push straight with the nose pointing slightly down. Do not throw your model with nose up, or at greater angle than 10 degrees down. The model must have a certain minimum speed from the very start to stay airborne. It is not enough to just place your model in the air. It is better to land in tall grass in order to prevent any damage to your model during initial trimming. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> If everything is OK (correct wing and tailplane alignment, correct CG position) TARA will fly with the wings level in a nice glide with her nose pointing slightly down. If the model glides straight down to the earth a few paces in front of you, check the CG position again. If OK, add a thin piece of balsa or Plywood under the trailing edge of the horizontal tailplane until the model glides in a nice flat and straight path. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once satisfied, bend the rudder '''52''' slightly (about 2 mm) to the left (looking from the tail to the nose). Now the model should glide in large left (counter clockwise) turns. Whilst under tow, the off-centre towhook would force your TARA right - resulting in straight flight. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Once trimmed out you can try your first hi-start with your TARA using 25–50 m towline (a fishing line). You can purchase a towline set in your local model hobby shop or you can make your own from scratch. Get a towline (any fishing line strong enough to hold 5 kg fish is OK), tie a key ring to one end (bowline knot is the best) and a flag (a piece of red cloth) 20–30 cm from the end. The flag makes the towline visible in the air as well as on the ground. Find a suitable spool to keep the towline on. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Hook the ring at the towhook and ask a friend to hold (and launch later) your model. Unwind the towline walking into the wind keeping is slightly stretched. The launch position of the model: wings level, nose very slightly up, directly into the wind. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> Give a signal to your friend holding your model. Both of you will start running into the wind, the assistant will launch the model after a few paces. Continue running into the wind paying attention to the tension of the towline and checking the model over your shoulder. Run as fast as necessary to achieve steady climbing rate of your model. The model should climb straight forward, at steady rate, in a nice arc. The stronger the wind, the slower you might run. If the towline tension decreases, your model climbs slowly (and yaws to a side) you should run faster. If the towline tension increases and the model violently turns to a side, you have to slow down and wait until the model returns to the original straight path. Hi-start requires some skills - especially on a windy day running too fast might even end in destruction of your model. Once the mode climbs almost over your head, it should start turning slightly left – this is the moment to stop. Let the model fly in front of you and release the towline. For the initial high start, set the towhook to the forward position. Based on the TARA's behaviour you can move it back/adjust later. If your model hesitates to climb, move it back. If pitches the nose up and veers to side, move it forward. Adjust the rudder to achieve large flat left turns. Tight banked turns kill the altitude! Usually, just 2 mm left offset is OK. Contest flyers would want to install the dethermalizer with a timer that kicks the horizontal tailplane up (about 45°) once the set time has elapsed. The model will land in large "hoops" then. </div> <div lang="en" dir="ltr" class="mw-content-ltr"> === The kit contents === {| class="wikitable" !'''Part''' !'''Building plan no.''' !'''Quantity''' |- |Fuselage block – 8 mm ceiba Plywood |(24) |1 |- |Side cover – 3 mm poplar Plywood |(26, 28) |2 |- |Vlies tissue sheet (1230×330 mm) | |1 |- |Vlies tissue sheet (200×410 mm) | |1 |- |Colour tissue trim sheet | |2 |- |Sand paper | |1 |- |Building plan | |1 |- |Instruction manual | |1 |- ! colspan="3" |'''Stick bundle A''' |- |Fuselage stick - spruce 2×8×595 mm |(22, 23) |2 |- |Wing leading edge - balsa 8×8×645 mm |(2) |1 |- |Wing main spar - spruce 3×8×645 mm |(7) |1 |- ! colspan="3" |'''Stick bundle B''' |- |Wing leading edge - balsa 8×8×260 mm |(48) |2 |- |Wing trailing edge - balsa 14×4.7×330 mm |(3a, 3b) |2 |- |Wing trailing edge - balsa 14×4.7×260 mm |(40) |2 |- |Spruce stick 3×5×405 mm |(11) |1 |- |Spruce stick 3×5×395 mm |(14) |1 |- |Spruce stick 3×5×197 mm |(10) |2 |- |Spruce stick 3×8×245 mm |(49) |2 |- |Balsa fuselage block – thick |(20) |1 |- |Balsa fuselage block – thin |(21) |1 |- |Balsa stick 3×5×300 mm |(12) |6 |- ! colspan="3" |'''Rib set bag A''' |- |Main wing rib |(1) |14 |- |Support rib |(6) |3 |- |Wing end rib (bevelled) |(5) |2 |- |Rib set bag B | | |- |Wing panel root rib (bevelled) |(47) |2 |- |Wing tip |(50) |2 |- |Wing panel rib |(41–46) |12 |- ! colspan="3" |'''Bag C''' |- |Fin |(29) |1 |- |Bottom fin |(37) |1 |- |Wing seat plate – Plywood 1.5 mm |(36) |1 |- |Wing centre sheeting - Balsa 1.5 mm |(4, 8, 9) |6 |- ! colspan="3" |'''Small parts bag D''' |- |Balsa plate – Balsa 3 mm – 30×80 mm |(13) |1 |- |Balsa plate – Balsa 3 mm – 30×30 mm |(16) |1 |- |Balsa plate – Balsa 3 mm – 13.5×45 mm |(17) |2 |- |Wing joiner "V" |(42) |4 |- |Gusset |(10, 15, 51) |18 |- ! colspan="3" |'''Small parts bag E''' |- |Rudder |(52) |1 |- |Fin reinforcement plate |(30) |1 |- |Rear horizontal tailplane seat – Balsa 1.5 mm – 8×10 mm |(33) |1 |- |Towhook |(39) |1 |- |Rubber thread Ø1×600 mm | |1 |- |Horizontal tailplane seat – Plywood 1 mm – 25×15 mm |(31) |1 |- |Spruce Stick – 3×5×25 mm |(32) |1 |- |Bamboo dowel Ø2.5×25 mm |(34, 35) |2 |- |Bamboo dowel Ø2.5×50 mm |(18) |1 |- |Beech dowel Ø4x32 mm |(25) |2 |- |Screw 2×8 mm |(38) |2 |- |Ballast Ø26×8mm |(27) |1 |- |Rudder hinge (brass tin) |(53) |2 |} </div>
