    Fei bao hawker hunter thank you for buying our large scale hawker hunter, which has been developed to be quick to assemble and a pleasure to own and fly. The hunter is a large, heavy and sophisticated model and as such it is vital that great care and attention is taken during assembly to ensure a sa...

    Offer the elevator servo into place on the underside of the hatch and temporarily hold in position with the mounting screws. Fit the servo horn to the servo and mark the hatch where the pre-formed slot has to be enlarged to allow full deflection of the servo arm – including trim range. Remove servo ...

    Cover the underside of the elevator directly behind the elevator servo horn position with masking tape, then use a ruler or straight edge to draw a line across the elevator in line with the servo horn. Draw a second line 5mm outboard of the previously drawn line – this is the centre line of the slot...

    Repeat for the second elevator servo and horn. Assemble the elevator pushrods using either ball joints or clevises at both ends and check for full and free travel, making sure that the servo arms or pushrods cannot jam in any position. It may be necessary to bend the pushrods slightly to allow adequ...

    Fit the tailplane to the fuselage as shown – ensure the screws are fully tightened and consider using a threadlock compound. The rudder linkage is internal, see photos below. Fit the rudder complete with linkage to the fin and then install the rudder servo as show, finally centreing the servo and ad...

    Fit the fin/rudder assembly to the fuselage and securely tighten the fin post clamping screws. Wings: commence wing assembly by removing the large cover/door hinge mount from the wing panels by undoing the three screws, then unscrew the main undercarriage units from their mounts and disconnect the l...

    Reinstall the retracts and connect up the 3 air lines, these should be run out of the wing root together with the aileron and flap extension leads. Note that thin cyanoacrylate can be run into the retract mount screw holes to toughen the threads in the fibreglass/ply mounts. Refit the various gear d...

    Refit the nose retract unit into the model – note that prior to fitting thin cyano glue can be poured into the screw holes in the retract unit mounting plates to toughen the wood. Make sure the glue is completely cured before finally re-fitting the nose retract unit. Run the nosewheel steering servo...

    Connect up all the fuel lines and fit a suitable overflow through the underside of the fuselage with the fuel filler in a convenient to access position. Rear fuselage and tail surfaces connect air lines to the underfuselage airbrake, and check for any leaks, as this is impossible to do when the mode...

    Fit the mounting lugs to the bellmouth section of the tailpipe and slide the tailpipe into the rear section of the fuselage..

    Fuselage assembly bolt the front and rear sections of the fuselage together using the four m4 bolts and washers supplied, ensure these are completely tight and recheck these during routine maintenance. Connect up extension leads to the leads from the tail servos and lock or tape together for securit...

    Check the alignment of the tailpipe and then drill pilot holes through the mounting straps and into the sides of the turbine rails, note that it may be necessary to add a pair of wooden blocks above or below the rails depending on the final installed position of the turbine, to accept the tailpipe s...

    Fit the supplied air ducting as required, cutting it down to suitable length to allow for installation. Continue the installation of the remaining on-board equipment; the prototype used a powerbox royal srs twin receiver/battery system being powered by 6.6v 3000mah li-fe batteries..

    To keep the relatively heavy batteries as far forward as possible a former can be glued into place in the forward fuselage as shown, and a battery plate made up that slots into this and which is retained at the rear with a couple of bolts glued through the former with wing nuts securing the plate in...

    If the sabrinas are to be fitted the areas of fuselage that these are glued to should have the paint removed, as should the base of the sabrinas, before they are carefully glued into place..

    Operation of the sliding canopy can be by an electric actuator or air ram, this prototype using the air ram method, with a simple bellcrank arrangement to increase the travel to the required amount. A cross beam system was used to equalise the movement on both sides of the canopy..

  • Page 20

    Note that the fuselage section at the rear of the cockpit was cut away as can be seen in the photo above, and pins fitted to the rear of the scale cockpit that slide into the holes seen above. This allows the entire scale cockpit to be pulled forward through the access provided by the open canopy un...
