    Flying Strega..............................23 Introduction The RC glider Strega from RCRCM is a full on F3F/F3B sports model. It is ideal for the ambitioned RC amateur pilot who wants a high end all-round glider that features excellent thermal flying- but also speed flying- capabilities.

    (for plane surface protection) at hand. First lay out all parts. Here is what you should find, see figure 1. Figure 1. List of Strega kit parts: (a)Wings; (b)accessories [see insert on the upper left; 16 clevises, 8 threaded rods, 4 control horns]; (c)wing servo mounts; (d)wing servo-bay covers; (e)ballast tube; (f)fuselage servo tray;...

    Ballast: It is best to order the Strega ballast set together with the kit via https://www.rcrcm.com. For the fixed mounted nose ballast I suggest to use lead shots, widely available in RC stores. Get at least 150g. Wiring Harness: Probably available at RCRCM in future. Even so, mine is self soldered. To do this, get about 4m three pole 0,34 qmm servo cable, 2 green multiplex plugs for wing connection and about 10 connector plugs for the RC system of your choice.

    Figure 2. Taper the control surface sealing lips: First cover your working table with a soft cloth, such as a fleece blanket to protect the wing surfaces. Next, apply masking tape onto the respective wing and control surface (left panel). Now, use a sanding block to bevel the sealing lips carefully. Be careful to keep the “angle of attack”...
  • Page 6 Figure 4. Prepare the control horns for flaps and ails. Measure the diameter of the little perpendicular rod inside the clevises. Now choose a drill with a diameter slightly smaller than what you just measured and carefully drill through the clevis-attachement hole of each control horn (upper left). Now the clevises can be attached (upper right).

  • Page 7: Installation Of The Wing Servos

    Figure 5. Mount the control horns: it is best to fix the control surfaces in a 90˚ angle to the wing using masking tape, first. Now have a look at the upper panel. This describes exactly how to fix the control horns respective to the hinge of each control surface.
  • Page 8 Figure 6. Prepare the servo horns and clevises for the wing servos. First drill a hole through the servo horns (for choice of drill see figure 4) 2,5mm outside the servo horn base (upper panels). The clevises will need to be milled on the bottom side to allow for full movement respective to the servo horn shaft (middle panel and lower left panel).
  • Page 9 Figure 7. Prepare the servo frames: Mill down the servo horn side of each of the four servo frames (left panel) to allow for full movement of the servo horns (middle). Check if full range of motion is allowed for (middle).
  • Page 10 Figure 8. Fix the servo frames in the wings: First, wrap each servo with saran wrap (upper left). Next, briefly sand servo bays and bottom of servo frames and push each (saran wrapped) servo into its respective servo frame (upper right). Now mix the endfest epoxy, add some cotton flakes (or microballoons) for thixotrophing it and smear it into the fine sanded servo bays and onto the bottom of the servo frames.
  • Page 11 Figure 9. Adjust the ail and flap linkage systems: Fix the wing servos with the appropriate screws. Therefore, you first might need to grind off a little from the surrounding wing (upper left & right). Next screw the clevises onto the supplied metal threaded rods to create pushrods (upper middle panel). Now they need to be adjusted.
  • Page 12 Figure 10. Soldering wing -pushrods and –cable trees: To ensure a tolerance free fit of your flap and ail linkage systems it is advisable to permanently fix both clevises on either side of the threaded rod by using super glue or, as shown here by soldering them (upper left). For the end result, see (upper right). While you’re at soldering, I suggest to also prepare the wing cable trees.
  • Page 13 Figure 11. Mount the wing sided multiplex plugs: A little tuning of the servo cable outlets is needed to ensure that the plugs can move freely in there (upper left). Solder the cables of both wing servos onto the male plug (upper right). Next, wrap some transparent tape around the plug and cables and fill the resultant cavity with 5min epoxy (lower left).
  • Page 14 I personally used transparent plastic plates so that you can see the servo below (lower image). If that is done the wings are all ready to go! Now prepare the fuselage side of the wing servo cable connectors. Figure 13 shows readily assembled Strega wings.
  • Page 15 Figure 13. Readily assembled Strega wings. Test for proper function of the wing RC system as soon as the fuselage sided wing servo plugs and corresponding receiver cables are installed. Now that the wings are all finished the RC equipment as well as the ballast tube need to be installed in the fuselage.

  • Page 16: (Making And) Mounting The Servo Board

    (lower right). (Making and) mounting the servo board The Strega fuselage is quite narrow, which helps to achieve excellent aerodynamics. So, before you start with any RC equipment installation procedures you need to know the kind of battery, receiver, servos and switch e.t.c., e.t.c. that you will want to use. Put it all into the fuselage and keep in mind that there still needs to be space behind the servo board for ballast tube mounting and in front of all RC gear for the nose ballast.
  • Page 17 Figure 15. Lineout for the RC gear in the fuselage: Before you buy the RC gear think about the way you want to install it in the fuselage. I found that parallel installment of two KST 215 servos in conjuntion with 2 lithium ion batteries placed in front of the servos gives me plenty of space in the fuselage for all other RC gear needed, see figure.

  • Page 18: V-Tail Linkage

    Figure 16. The servo board: To save precious space in the fuselage cut out your own servo board from 4 mm plywood using the supplied one as rough template (upper left). I used 3mm plywood and laminated one layer of 80g glass on top and bottom. Make sure the board fits perfetly but thightly in the fuselage at your desired position.

  • Page 19: Ballast Tube

    rods with clevises permanently connected, to get a close to zero tolerance linkage system. Figure 17 will guide you through that process. Figure 17. V-Tail linkage: Upper left. Use the long carbon rods that are delivered with the kit (figure 1g). Fiddle them into the fuselage.
  • Page 20 (see the 2 upper right panels). After you have mounted the ballast tube the plane is essentially ready. Now you will need to set it up properly for the maiden flight. Figure 19, readily assembled Strega awaiting its maiden flight.

  • Page 21: Setup Of The Plane

    Figure 19. Readily assembled Strega. Before you perform the maiden flight, there are as few more things to be considered. Setup of the plane The important parameters here are the CG and the deflection levels of the control surfaces. As a first step insert and connect all needed radio gear in the plane. Again, you can use figure 15 as a rough guide for placement of each part.
  • Page 22 Figure 20. This is the setup I suggest to use for the maiden flight. After all the building and setup work you will be very eager to perform the maiden flight. So was I, figure 21.

    Figure 21. The author holding the readily assembled and set-up Strega in hands. Ready for the maiden flight! Flying Strega For your first flight, choose a nice slope that you know well. The wind speed should ideally be at a constant 15-20 km/h.
  • Page 24 Figure 22. Strega in mid air during a nice medium speed turn while performing the maiden flight. Strega is not really fickle and you can fly it quite slow, especially in thermal setting. However, for the beginning you want to fly it rather at medium speed. Keep the nose in horizontal position through the transitions, not only using ailerons and elevator but also rudder.
  • Page 25 RCRCM and will be available soon. Cheers, Paul Acknowledgements go to the RCRCM team and especially to Linda who provided me with the opportunity to test Strega. Also thanks to my friend If, who gave me invaluable tips and went flying with me several times.
