  • Page 9: Assembling The Model

    Micro Star 1000 1. Assembling the model Remove the factory-assembled rotor head from bag “A”, together with the control bridge, which consists of two halves; open the bag of screws at the same time. Remove the flybar from bag “G”; it is 2 mm in diameter and around 29 cm long.
  • Page 10 Micro Star 1000 Screw the two Hiller paddles onto the ends of the flybar as far as they will go. Check that both paddles are exactly the same distance from the centre of the rotor head. Fig. 3 Securing the flybar paddles Align the flybar paddles parallel with each other and with the control bridge, as shown in the drawing (right-hand main rotor rotation, i.e.
  • Page 11 Micro Star 1000 In the kit, the sub-assemblies shown below are supplied in pre-assembled form; the exploded drawings are only required for repair and maintenance purposes: Fig. 6: Collective pitch compensator Fig. 7: Swashplate Fig. 8: Swashplate -> rotor head pushrod...
  • Page 12 Micro Star 1000 As shown in Fig. 10, the sub-assemblies prepared thus far can now be fitted on the main rotor shaft, which is found in bag “A”: Fig. 10: Main rotor and shaft (excl. rotor blades) The lower collet with the two M3 x 4 grubscrews is supplied in bag “C”.
  • Page 13 Micro Star 1000 The next step is to assemble the main chassis from the parts in bags “C” and “D”, and also the separately packed side frames from bag “B”; the procedure is shown in the drawings below. When fitting the main rotor shaft bearing brackets please note that the bearings in the upper bearing bracket face up, and those in the lower bearing bracket face down.
  • Page 14 Micro Star 1000 The bellcranks for the swashplate control system and the cabin supports should now be at- tached to the prepared chassis. The bellcranks are supplied with linkage balls and ballraces al- ready fitted, and not separately as shown in the drawing: Fig.
  • Page 15 Micro Star 1000 The individual sub-assemblies can now be brought together as shown in Fig. 15; please note the following points: the tail rotor is on the right-hand side, as seen from the tail looking forward. The tail rotor drive belt has to twist through 90° to the right (clockwise), as seen from the front (take care not to turn it more than once !!!).
  • Page 16 Micro Star 1000 Set the three pushrods to the stated lengths, and use them to connect the swashplate to the bellcranks. Fit the prepared tail rotor head on the tail rotor shaft, as shown in Fig. 16. Please note the follow- ing points: The M3 x 3 grubscrew must engage in the depression in the tail rotor shaft;...
  • Page 17 Micro Star 1000 The swashplate and tail rotor servos are installed using the fittings supplied in bag “D”, as shown in drawings 17 and 18. Please note that the two pushrods for each push-pull linkage must be exactly the same length. The lever length of the servo output arms must also be 12 mm, so that the hole spacing is exactly the same as that of the bellcranks.
  • Page 18 Micro Star 1000 Fig. 19: Installing the tail rotor servo The drive motor is attached to the motor mount as shown in Fig. 20, which must first be re- moved from the chassis for this purpose. The moulding features slots for mounting the motor, designed to enable the builder to set the requisite very slight meshing clearance between the motor pinion and the main gear.
  • Page 19 Micro Star 1000 The carbon fibre stabiliser panels should be fixed to the tail boom using the fittings included in bag “F”, as shown in Fig. 21. The horizontal stabiliser is installed using the two-part clamp; ini- tially fit just the two M2 x 16 screws and the two M2 nuts on the underside; don’t fit the two M2 x 14 screws at this point, as they are used later to retain the tail boom braces.
  • Page 20 Micro Star 1000 The tail boom braces - also in bag “G” - are fitted with a ball-link at one end; the M2 x 14 screws which secure the horizontal stabiliser pass through these ball-links and into the clamp, as shown in Fig.

  • Page 22 Micro Star 1000 For this reason if you are using a Graupner radio control system we recommend that you start by programming the “throttle limiter” function at the transmitter. If you then close the throttle lim- iter, the motor cannot start running even if you advance the throttle stick accidentally.

  • Page 23: The Set-Up Procedure

    Micro Star 1000 2. Set-up procedure 2.1 Setting up the cyclic control system The basic settings for the roll-axis and pitch-axis control systems should already be correct if you have set up the linkages as described earlier in these instructions. Since the lever lengths are pre-defined, the final set-up should be carried out using the electronic facilities provided by your transmitter.
  • Page 24 Micro Star 1000 • The “normal” power curve is suitable for hovering and circuits. • The “aerobatic” power curve prevents the motor stopping at any position of the collective pitch stick. This means that you must only select this curve when the model is already flying.

  • Page 25: Adjustments During The First Flight, Blade Tracking

    Micro Star 1000 7. Gyro adjustment Gyro systems damp out unwanted rotational movements around the vertical (yaw) axis of the model helicopter. They do this by detecting the unwanted motion and injecting a compen- satory signal into the tail rotor control system. In order to achieve this effect the gyro electron- ics are connected between the tail rotor servo and the receiver.

    Micro Star 1000 There are two alternative methods: figure “A” shows different colours on the blade tips; fig. “B” shows the use of the same colour, but applied at different distances from the blade tip. Procedure for adjusting blade tracking 1.
  • Page 27 Micro Star 1000 7. Some basic terms used in model helicopter flying The term “rotary wing machine” indicates that the helicopter’s lift is derived from rotating “wings” which take the form of rotor blades. As a result, a helicopter does not require a minimum forward speed in order to fly, i.e.
  • Page 28 Micro Star 1000 this prevents the rotor plane tilting excessively in forward flight. In model helicopters a single hinge shared by both blades has proved an effective solution to the problem. Auto-rotation This term refers to a helicopter flying without motor power. The rotational speed of the main rotor can be kept high by setting both blades to negative pitch;...
