INSTALLATION OF THE MOTOR TRANSMISSION SETUP It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance. It is recommended to use wiring and connectors appropriate for the currents generated in a helicopter of this class. If you are using a head speed calculator which requires a main gear and pinion tooth count, use 216 teeth for the main gear (this takes into account the two stage reduction) and the tooth count of your pulley as the pinion count.
INSTALLATION OF THE MOTOR Foam 1, BAG19 Socket Head Cap Screw M3x8mm (HC050-S) 3rd bearing support for the motor, H0143-S Install the support after installing the pulley and after mounting the motor.

INSTALLATION ESC/FBL/RX BAG23 Use hot glue to secure the wire connections. ESC Wire Servos Wire HA074-S Glued connector on the Carbon Support Zip-tie [HA058] Follow the illustrated wiring solution. Use the servo extension for connecting the tail servo. Servos Wire Tail Servos Wire Gluing of the connector on the carbon support is recommended as show in Figure 2.
INSTALLATION BATTERIES BAG24 Before permanently mounting the batteries onto the battery tray, check the ideal position for the best center of gravity. BATTERIES Use the included double side tape to secure the batteries to the tray. Use the Velcro Strap [HA041-S].
INSTALLATION CANOPY BAG25 CANOPY *Install Canopy grommets (Figure.1) and the two quick knobs (Figure.2) *Fit the canopy in the red arrow zone, and insert the knobs. *Confirm the canopy is secure prior to each flight. Canopy Kraken (H1075-S) Canopy Grommet (HA021-S) NOTE: Quick Knobs NOTE: Put a very small drop of CA glue on the grommet and then insert the quick release canopy mount. This way when you remove the canopy, the mounts can not come off.
IN FLIGHT BAG26 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.
MAINTENANCE MAINTENANCE Take a look at the red parts. 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. In some instances, based on wear, these parts should be replaced every 100 flights. Periodically lubricate the tail slider movement and its linkages as well as the swash plate movement and its linkages.
TRANMISSION MODULE TRANMISSION MODULE The transmission module is supplied assembled and verified, ready to be used. Explode and Spare Parts K Gear Z72 0,75 (H1050-S) For replacing the main shaft: *Remove the serial number plate *Remove the M4x21 screw *Remove and replace the main shaft *Screw in the M4x21 screw, with high force and using green loctite Main Shaft (H1054-S) Use SAB HA076 Grease inside the module.
CHECK LIST 1 Check the dampening on the main and tail rotor to be the same as always. 2 Tighten the main blades before flight. 3 5 Check Tail & Motor belt tension. The tension has to be tight. 6 Check the 4 M3x12 Tail group screws. Ensure they are tight. 7 9 Check for vertical play of the main shaft. Check if the FBL-RX connectors are OK 10 (hot glue is recommended). Check main hub screws(M4x24 and 2 M3x12) Ensure they are tight.
