Some notes in advance:
Please read these assembly and safety instructions carefully before starting construction and
proceed step by step when building. Make sure you understand the individual building steps.
This kit is suitable for children from 14 years old. Construction and operation of the airplane
should be under the supervision of an adult.
The flight model is suitable for E-RES competitions, slope and thermal flying in calm weather.
Caution: high flight is not appropriated. At high altitudes and in windy conditions, it may not
be possible to estimate the correct flight speed.
The manufacturer gives no liability for damage resulting from improper use.
A non-intended use is, among other things, to assemble the kit differently as descripted at
the following construction manual or to use the flight model differently as described in the
assembly instructions.
When building the model, observe all safety regulations for handling tools and adhesives.
We use thick and thin superglue for assembling the model unless otherwise specified.
Particular care must be taken to ensure that the components are properly glued.

  • Page 1 E- Purito Holzmodellbau Schweiger construction manual Some notes in advance: Please read these assembly and safety instructions carefully before starting construction and proceed step by step when building. Make sure you understand the individual building steps. This kit is suitable for children from 14 years old. Construction and operation of the airplane should be under the supervision of an adult.
  • Page 2 Description electric fuse: We start with the fuselage slipway: the parts of the slipway are on a separate 3mm poplar plywood board. The stops are carefully cut out and glued into the slots provided. Stop 1 is provided for slot 1, stop 2 for slot 2, etc.
  • Page 3 As shown in Fig. 3, we use a roller for gluing R9 and R10. This allows the glue to be applied in an evenly thin layer. Press the parts together for several hours. Glue the balsa strips R8 flush to the fuselage sides at the bottom. Now glue the wing supports made of plywood R6 flush on the top of the fuselage sides.
  • Page 4 Now the fuselage can be test-fitted together. The fuselage sides are assembled with all formers and the wing bolting and plugged into the fuselage slipway. Tip: We screw the fuselage slipway to our building board! This ensures that it lies cleanly and the hull can be built up without distortion. When all parts fit together properly in the slipway, they can be glued.
  • Page 5 Now parts R25 are glued to both sides of the fuselage, part R26 should be glued to the bottom of the fuselage and part R27 to the top of the fuselage, centered between the two parts R25 (see picture). The parts R25-R27 are there to fit the fuselage to the spinner later. On the top of the fuselage, glue the balsa part R17 between the canopy opening and the engine bulkhead, here the wood grain runs crosswise.
  • Page 6 Make sure that the canopy reaches the necessary bend. Tip: We carefully harden the slot in canopy R18 with liquid super glue. This prevents pressure marks in the balsa wood caused by opening and closing the canopy. The plywood part R23 is glued inside the canopy to the fuselage tip center, serving as a tongue. Glue the balsa part R21 to the end of the canopy between the plywood strips.
  • Page 7 Fuselage tube and pylon: The fuselage tube made of CFRP should be wet smoothed with water sandpaper. We recommend a grit of 400 or finer here. You will need: the 4 solid carbon rods with a diameter of 2mm, 2 each for the elevator and rudder.
  • Page 8 Rudder and elevator: The 4mm balsa board with the parts for the elevator and rudder are needed for building. The reinforcement part made of 4mm poplar plywood is in the accessories package. Additionally there are 3 parts (S4-S6) for the rudder on the 8mm balsa board.
  • Page 9 Assembly of the fuse: Now the fuselage tube can be joined to the fuselage boat. The wing support is checked once again for protrusions to ensure a flat support surface for the wing center section. Rudder and elevator 90 degrees Elevator and auxiliary rail parallel Support 1cm before...
  • Page 10 A straight line is drawn on the building board, extending along the entire length of the hull. The fuselage tube is inserted into the fuselage boat so far that it protrudes 2mm from frame The frame R5 is inserted into the rear of the fuselage boat. 1cm before the end of the fuselage boom the support made of 3mm balsa is inserted.
  • Page 11 Grinding of fuselage and tail unit: When sanding the hull, we start, as just mentioned, with the transition from the Hull boat to the hull outrigger. For this, the fuselage boom must be taped off Avoid damage caused by grinding. Be careful here: if the CFRP tube of the fuselage boom is damaged by the grinding, a Predetermined breaking point.
  • Page 12 The sanding batten on the trailing edge of the tail unit and the Edge of the table. So grind we the trailing edge down to ours Auxiliary line from both sides (approx.1mm) pointed.In contrast to the trailing edge, the we just sharpened it to a point we grind them The leading edge of the tail units is round.For this we grind on both Sides of the...
  • Page 13 INSTALLATION OF THE BOWDEN CABLES: To ensure that the Bowden cables in the To reach the fuselage tube, we proceed as follows:A 0.8mm steel wire is inserted into the Bowden cable inserted at the rear end of the bowden cable must stand back about 2cm.
  • Page 14 Description of wings: We start with part C: In the picture are the required parts: base plate, matching ribs for part C, Edge curve, 5 degree stop, End strip, comb, 7mm CFRP tube(Spar) and the 2mm CFRP tube(Leading edge). I grind the CFRP pipes along with 200 water sandpaper easily and clean them up with dissolving agents.
  • Page 15 We use the 2mm CFRP tube as the leading edge, which is carefully inserted into the designatedMilling is inserted. Then the half-ribs can also be used with the comb neatly aligned and glued once The trailing edges are in front of the Shoring ground.
  • Page 16 The parts for the edge arch (1-5) are found in the 8mm balsa. These can be used after personal taste be glued together, we use an offset on the Trailing edge of approx. 2mm. Tip: here with one piece Household foil the building board protect the parts of the Edge arc with the straight one Place the underside and glue...
  • Page 17 Be careful here: the leading edge in Part A and B are 2.5 mm thick.(In contrast to Part C: here they are only 2mm thick). The wing part B is also again on the leading edge 2mm (under the feet of the Ribs) and on the trailing edge with 8mm underlaid.
  • Page 18 Now the rest of them can too Ribs are aligned. in the They will connect with the Glued spar. After this Step, can also do the Leading edge (CFRP tube 2.5mm) be attached at the front. To note now that the Comb for aligning the Ribs shortened by one field must become.
  • Page 19 The next step is that Border for the flaps in the area. It will be the parts KF1-KF2 from the 3mm, and the both strips KF3 from the 2mm balsa board required. KF3 is on the balsa board of the ribs (Part A). To note is here that there are two from KF3 different designs gives: once with the cutout for a servo...
  • Page 20 The parts for the airbrakes will be on the blueprint plugged together and then with liquid Superglue glued. The then slide the brake flap into the Cut-out in the middle part it in.Finally, the Magnets (diameter 4mm)on the underside, flush with the holes provided for this purpose Brake flap, glued in place become.
  • Page 21 We use for that Power connection to the hulla 5-pole spring contact.This is also with us as Accessories available. Like on that Can be seen in this picture Milled accessories too Plywood parts that contain the Spring cotter precisely fits into the Wing recording takes up.For this execution is Experience in soldering required...
