UNI-STAR 60 Accessories (use the instructions in the manual of the mechanics if building the electric version „TRAINER UNI-E“) Suitable mechanics: Order No. 4448.LN UNI-MECH. 2000 with OS MAX 91 motor Red. ratio 7.7 : 1 Order No. 4448.LN UNI-MECH. 2000 with OS MAX 61 motor Red. ratio 9 : 1 Order No. 4449.RXN, 4450.L UNI-Expert mech. with OS MAX 61 Red. ratio 9 : 1 Recommended main rotor blades: Order No. 1246B GRP, reflex 688 mm long Rotor Ø 1551 mm (Starlet: 1533 mm) Order No. 1266 CFRP, symm. 686 mm long Rotor Ø 1547 mm (Starlet: 1529 mm) Adhesives UHU plus schnellfest, Order No. 962, fast-setting UHU plus endfest 300, Order No. 950, slow-setting, for gluing GRP to wood UHU Blitz, thin cyano-acrylate, Order No. 5803 Thick cyano-acrylate, Order No. 1101, for tacking parts together Filler agent, e.g. Order No. 963, for thickening resin Tools required: Minimum set: assortment of files (round, half-round, flat), set of twist drills, light tin-snips, fretsaw, various screwdrivers, allen keys and general-purpose pliers. Coarse abrasive paper, e.g. 100-grit, Order No. 1068.1, for roughening joint surfaces and for sanding the GRP mouldings. Radio control system (see Mechanics manual and main Graupner catalogue) The model requires a radio control system equipped with special helicopter options, or a microcomputer radio control system such as the mc-12, mc-14, mc-15, mc-16/20, mc-22, mx-22 or mc-24. Servos (high-quality servos must be used), e.g. C 4421, Order No. 3892 Gyro: G490T SRVS gyro, Order No. 5137, with NES-8700G super-servo, Order No. 5156, or PIEZO 550 gyro system, Order No. 5147. Electronic speed governor: mc-HELI-CONTROL, Order No. 3286 Receiver power supply: For safety reasons it is essential to use a pack of at least 2000 mAh capacity. We also recommend a voltage monitor module, Order No. 3138, which allows you to monitor the battery voltage constantly. Switch harness: Order No. 3050; suitable receiver battery: Order No. 2568. 6
UNI-STAR 60 1. Assembly The following instructions describe how to assemble the tail boom from its component parts. Although the parts are supplied largely factory-assembled, you may need to know this information if repairs become necessary. Some components in this set are supplied factoryassembled. Nevertheless, it is up to the builder to check that the assembly work has been carried out correctly and that all joints are tight. Final adjustment is also left up to the builder. 1.1 Preparing the tail boom struts Glue the strut sockets 4447.8A into both ends of the two CFRP struts 1292.108 using slowsetting epoxy, e.g. UHU-plus endfest 300, Order No. 950. Check that the sockets are exactly parallel to each other, then leave the epoxy to set hard. 1.2 Preparing the mechanics to accept the tail boom Screw the mounting flange 1292.5 to the bearing holder 4448.14 on the mechanics using two M3 x 16 socket-head cap screws. At the same time fit the two M3 x 30 strut attachment screws to the mechanics side frames, together with the aluminium mounting bolts 4451.12. To do this you will have to unscrew the top rotor shaft bearing temporarily and slide it down; the M3 x 30 screws can then be fitted from the inside and screwed in to the point where their heads disappear almost completely into the side frames. Install the top rotor shaft bearing again. 1.3 Tail boom The front end of the tail boom is curved, and the effect of this is that the tail boom rises towards the tail. This feature increases tail rotor ground clearance, and also ensures that the tail rotor drive shaft runs in a broad, smooth curve, and therefore has no tendency to oscillate. 1.4 Preparing the tail boom Push the two tail rotor drive shaft supports 1292.10A into the tail boom 4451.109 using a length of beech dowel or similar. The front support should be located 200 mm from the front end of the boom, and the rear support 300 mm from the tail end; in both cases the spherical cavities should face forward. Working from the front end press the guide ring 4451.7 into the tail boom to a depth of exactly 27 mm, with the conical opening facing the rear; when the parts are assembled this ring guides the retaining sleeve accurately onto the coupling yoke. The front shaft coupling can now be prepared: when completed the coupling should automatically engage correctly inside the tail boom, without requiring you to align it or use any tool. This in turn means that the brass coupling sleeve 4618.58 needs to be an easy sliding fit over the coupling yoke 4618.57. If necessary remove any rough edges from the yoke and 7
