Required items for operation This is the general list of items required to get started on any nitro R/C helicopter. Century produces a full spectrum of accessories and tools to assemble your helicopter. The Hawk Pro is a mechanical cyclic collective pitch mixing type helicopter requiring a standard helicopter radio (the helicopter radio does not require eCCPM type mixing for this model). The Hawk Pro uses 5 servos to operate critical systems. Gyroscopes are required to operate the model safely.
Package contents: Opening The Hawk Pro for the first time Time to inventory your Hawk Pro! The helicopter is assorted into multiple bags contained inside the box. Each bag will have some parts that are not associated with that specific part bag. We recommend organizing all hardware and pieces and inventory them then keep them with their respective bags. It is common to have a few screws and/or washers left on the side after the build.
Section 1: Preparing the engine 1.1 Remove the thrust washer that comes on the engine from the factory. Only use the 9x14 washer that comes with the fan and clutch package. Mount that washer first and the clutch (1.1-1.2) to the engine using thread lock. Mount the fan so the two protruding portions on the underside slide into the slots machined in the clutch (1.3). Remove the stock engine throttle arm and use the one provided with the helicopter kit. (packed with the fuel hardware/pushrods pack).
Section 3: Installing servos to servo tray 3.1 Insert and attach the lower throttle servo on the left side (3.1) with the output “horn” facing the front of the servo tray. Install the upper collective servo above the throttle servo with the output facing the back (3.2). Attach the aileron servo (3.2) to the middle of the top portion of the servo tray with the horn facing forward. Attach the elevator servo to the left of the aileron servo horn facing rearward (3.2). Attach the power switch (3.
Section 5: Muffler & fuel routing 5.1 Using thread lock: Hardware provided with muffler Install the pressure nipple using a high temperature adhesive (thread lock) to the top of the muffler and the 4mm plug screw to the bottom (5.1). Bolt the muffler to the engine (5.2) flush (no gasket required) using thread lock. Connect fuel tube between the fuel pickup in the tank and the carb on the engine with as little slack as possible (5.3).
Section 7: Landing gear 7.1 All components for installing landing gear are included with the landing gear bag. Attach the plastic U shaped struts to the bottom of the main frame and insert the metal skids when aligned (7.1). Bolt the landing gear to the main frame using provided hardware (7.2). Attach the skids only when helicopter will sit level using the provided set screws and CA glue (7.3). At the end of this section the helicopter should be able to stand upright (7.4).
Section 9: Tail boom supports & tail fin set 9.1 Attach the tail boom support struts to the base of the side frames using the plastic spacer on the outside of the frame (9.1) . Attach the horizontal fin (hardware found inside fin bag) and tail boom supports onto the horizontal boom clamp (9.2 use the white plastic piece found with the canopy grommets between the fin clamp and the fin). Screws are provided for mounting the vertical fin in the package containing the fins (9.3).
Section 12: Cyclic servo linkage Aileron servo Before any pushrod adjustments are made center both sticks and servos on the transmitter. *Pushrod measurements include ball links from plastic end to plastic end. Adjust the two aileron control rods to 158mm and attach the two balls on the aileron servo wheel and to the two aileron bellcranks. Adjust the elevator control rod to 135mm and attach to the elevator servo arm and elevator bellcrank.
Section 16: Antenna routing Thread the small clear tube into the guides (located on the right bottom side of the struts) on the side opposite the muffler. Insert the receiver antenna into the tube and secure to the rear area of the tail boom or one of the boom support struts. It is recommended that you use a small rubber band to do so. Section 17: Mounting the canopy 17.1 Carefully cut out the windshield area from the canopy (17.1) with a sharp hobby knife.
