Chapter 9, Installation Of Swashplate Servos INSTALLATION OF SWASHPLATE SERVOS The linkage ball must be positioned between 16-18 mm out on the servo arm (figure 1). The 120° placement of the servos inside Goblin means the arms are difficult to access. For this reason it is advisable to ensure alignment of the servo arms (and sub trim set) before installation of the servos in the model (figure 2). Proceed with installation following the instructions below. Figure 3 shows a completed installation.
Chapter 12, Installation Of The Motor The wire for the front servo must be positioned here. Tool HA002 If it is necessary to tighten the horn screw, use the included hexagonal wrench (HA002). Head Preliminary Setup Linkage Rod A Assembly . . . .x2 Approx. 75mm Adjust the linkage as shown. The linkage Rod A has thread right / left. Turning, you can change the tracking without disconnecting the plastic ball link.
Chapter 10, Installation Of The ESC DE-BURR THE SIDE FRAMES We recommend de-burring the edges of the carbon parts in areas where electrical wires run. ESC INSTALLATION There are two mounting options: Mount using part # H0004 (ESC Aluminum Support) Typically used for Kontronik Jive 120. The speed controller is placed on top of the aluminum support. (Fig. 1) Mount using part #H0153 (ESC Carbon Support) (Fig. 2) Typically used for ESCs with aluminum cases, such as Kontronik Kosmik (Fig. 3).
Chapter 11, Installation Of Flybarless Unit and RX FLYBARLESS CONTROL UNIT AND RX INSTALLATION It is possible to install any commercially available Flybarless control unit in the goblin. For Flybarless systems with a separate sensor, the sensor must be installed under the plate (Figure 1). Figure 2 shows an example of installation of the receiver and flybarless control unit. In Figure 3 you can see the extension lead for the tail servo.
Chapter 12, Installation Of The Motor TRANSMISSION SETUP It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance. The Goblin has many possible reduction ratios at your disposal. It is possible to optimize any motor and battery combination. It is recommended to use wiring and connectors appropriate for the currents generated in a helicopter of this class.
Chapter 12, Installation Of The Motor MOTOR BELT TENSION *Assemble the motor and pinion to its mounting plate. *Fit the motor assembly into position. *Compress the springs by pushing the motor toward the main shaft. *At maximum compression, temporarily tighten one of the slide screws. *With the minimum centre distance it is easy to install the belt. First put the belt on the motor pinion. *Then put the belt around the big pulley. *Rotate the motor several times by hand.
Chapter 13, Installation Of The Boom BOOM ASSEMBLY *Insert the tail boom assembly making sure that the aluminum part of the tube touches the M3x16 screw. *Lock the M8 nuts with the HA005 special tool supplied (Tray 2). *Firmly lock the lateral M3 nuts. *Assemble the H0038 carbon security plate . *Connect the tail servo wire to the previously fitted extension lead. Socket Head Cap Screw M3x8mm ....x1 Finishing Washer M3 ....
Chapter 13, Installation Of The Boom, Canopy TAIL BELT TENSION *Check the proper assembly of the tail boom. *Check that the aluminum part of the tube is against the M3 stop screw. *Loosen the tail group by loosening the 4 M3 screws. *Install the belt onto the pulley, taking care to respect the direction of rotation (figure 1). *Rotate the tail drive several times by hand.
Chapter 14, Battery BATTERIES The battery tray system in the Goblin 770 is simple, but very effective. The battery should be attached to the tray (Part H0149) with heat shrink, tape or velcro. You can optionally use the battery protection tray (Part H0151) see Fig. 1, 2. Before permanently mounting the batteries onto the battery tray, check the ideal position for the best center of gravity. Cut the heat shrink around the carbon fiber tray locking pins. Fig. 3.
Chapter 15, In Flight OPERATIONS BEFORE FLIGHT *Set up the remote control and the flybarless system with utmost care. *It is advisable to test the correct settings of the remote and flybarless system without main blades or tail blades fitted. *Check that all wiring is isolated from the carbon/aluminum parts. It is good practice to protect them at the points where they are at most risk. *Be sure of the gear ratio, verifying carefully the motor pulley in use.
Chapter 16, Maintenance MAINTENANCE *On the Goblin, areas to look for wear include: * Motor belt * Tail belt * Damper * Main gear and pinion The lifespan of these components varies according to the type of flying. On average it is recommended to replace these special parts every 100 flights. *The head tends to lose rigidity after a while. Check this condition every 20 flights. Preloading with precision shim washers, it is possible to vary the rigidity of the head. *Check all uniballs often.
