Chapter 14, Installation Of The Boom, Canopy Bag 14 BOOM ASSEMBLY * Insert the boom. This operation is easier fitting into the main frame at a slight angle [Fig.1]. To facilitate boom insertion, you can also unscrew the two bolts that hold the tail servo support tray. * Tighten the M8 nut with HA016 special tool supplied. * After installation, connect the tail push rod. * To lock the nut and prevent it from coming loose, install: - H0287 (for FBL unit installed on the main plate) [Fig.2].
Chapter 14, Installation Of The Boom, Canopy Bag 15 TAIL BELT TENSION *Check for the proper assembly of the tail boom. *Loosen the tail case by loosening the 4 M2.5 screws. *Install the belt onto the front pulley in the correct direction of rotation (figure 1). *Rotate the tail drive several times by hand. *Pull the tail case back to increase belt tension. *Tighten the 4 M2.5 screws on the tail case. *The belt must be very tight. CANOPY Fit the canopy to the main frame until it stops. [Fig.
Chapter 15, Battery Bag 16 BATTERIES The Goblin has a quick release battery tray system. The batteries must be installed onto the battery tray to take advantage of the quick release locking system. Install the battery to the battery tray using double sided tape and the long Velcro straps included (Fig 1 and Fig 2). Make sure to find the right position of the battery to optimize the center of gravity. The battery wires arranged as in fig 2 are particularly effective.
Chapter 16, In Flight Bag 17 OPERATIONS BEFORE FLIGHT *Set up the transmitter and the flybarless system with utmost care. *It is advisable to test the correct settings of the transmitter and flybarless system without main blades and 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 17, Maintenance MAINTENANCE *On the Goblin 380, some areas to look for wear include: - Motor belt - Tail belt - Dampers *The most stressed bearings are definitely those on the tail shaft and the thrust bearings. Check them frequently. All other parts are not particularly subject to wear. *The lifespan of these components varies according to the type of flying. On average it is recommended to check these parts every 20 flights.
