Build

With a sharp blade release all the foam board components from the backing sheet.

Carefully deepen the hinge lines on the ailerons and elevator without cutting right through then bend back to form a hinge.  If you cut through, just tape the component back in place with clear sticky tape.

Bevel the rearward side of the hinge surfaces forty-five degrees with a blade or sandpaper block.Use clear sticky tape to reinforce the hinge lines from underneath. Note picture is incorrect 45 deg chamfer should be on the elevator and likewise the ailerons.



Using a glue gun with a good flow rate glue the Tail Piece to the Main Wing. This best done on a flat surface being careful not to glue the assembly to the building board. Tip: Keep moving the parts around to prevent gluing to the bench. Use a scrap piece of foam board to remove any excess glue.



Important : The Tail and Bottom Deck both have the letters ‘BOT’ (meaning facing down) inscribed on them.  Check you have the correct orientation before gluing the top and bottom decks.

Take care that the slots are aligned between the sections.


Glue the Top Wing and Top Deck making sure all the slots line-up




Attach the Bottom Wing and Bottom Deck to the underside of the Main Wing.  It looks odd at first but makes sense when the Servo Wire Covers are installed later.




At this stage while the components can lay flat on the building board bevel or round the leading edge and reinforce with tape.

Attach the Bottom Fuselage Silhouettes.  The importance of aligning the slots is now clear. Pinch the end of the tabs between your fingers to make them easier to feed into the slots. Trim any proud tags flush with the surface.

 


Attach the Top Fuselage Silhouette.



Construct the motor mount assembly by gluing the four plywood sections together and inserting the popsicle sticks. Use wood glue for this task. Ie PVA/Titebond. Trim the protruding sticks and sand flush.



 Sand the front of the fuselage to a flat surface and attach the Motor Mount with hot glue to all surfaces.



Attach the Corflute underside of the fuselage with tape at the rear and bend to form a hinge.  Align the Corflute at the front.

 

Note that the Servo Wire Covers have been placed in position for illustration only.  Tack these in place after the servos have been installed.


Hot glue the servos in the wing and tack the Servo Covers in place.  Fit control horns and push rods.









Screw the motor to the ply Motor Mount using wood screws and attach the esc, receiver and battery with Velcro.

 

Important : The center of gravity should be 50mm from the leading edge of the wing.

We suggest setting up rates on all control surfaces and applying at least 30% to 40% expo.

Streamers are simply attached to the fin with sticky tape.

Stardust Half A Build

VARMS Stardust Half A Build Admin: Andy Smith  Cover Pictures: Alan Jenkins  Contributions: Alan/Gary/Tim/Kevin Background to the VARMS Half A Stardust  (VARMS)  Victorian Association of Radio Model Soaring Inc. was formed in 1968 to get together aero-modellers who were interested in building and flying radio controlled gliders)   Website:  VARMS During our Wednesday Half A events, it became apparent that the choice of aircraft and hardware significantly affected the competition outcomes. In some cases, the differences in equipment, rather than pilot skill, were the decisive factors in determining the winners. The main objective was to develop a standard-class model, encompassing both the airframe and hardware, to ensure a level playing field. This approach is intended to foster a friendly one-design Half-A competition on Wednesday afternoons, where the emphasis is placed on pilot skills rather than equipment advantages. The Stardust pro...
