Assembly Instructions for SkyWing Profile Aircraft

Assembly Instructions for SkyWing Profile Aircraft
This instruction manual relates to the following models
Edge 540
Slick
Yak 55
Assembly procedures for the above aircraft are very similar. In this manual, assembly images are shown for
the Edge 540 (blue) airframe. However, construction of the other airframes follows the same procedure.
EPP Parts
EPP foam is damage resistant but at the same time quite flexible.
If any of the airframe parts are bent or dented in transit they can
be laid on a flat surface with weights on top to straighten them.
Putting them in direct sunlight on a warm day may also help.
Unwanted creases and dents can be taken out by running hot
water over the affected part.
Other Parts
Ensure your kit contains fit out parts and landing gear
parts as shown here. The carbon rods will be taped to
the inside of the box.
Preparing to Build (Control Surfaces)
The control surfaces are left attached to the main frame to give you the option of how you want to attach
them. This is a matter of personal preference.
Option1.
With the control surfaces left attached to the airframe you can
simply smooth some foam sage glue over the join to reinforce it
and give it strength. Alternatively, you may prefer to run a length
of Blenderm or Du-Bro hinge tape along the join to add strength.
Option 2.
Cut the surfaces free from the airframe and use either foam-safe
glue or Blenderm or Du-Bro hinge tape to connect the surfaces.
This method may allow the surfaces to move more freely. You may
even prefer to hinge the surfaces with plastic hinges.
Prepare and glue the landing gear first to give it time to dry. Use either CA glue or Araldite to secure the
carbon in the braces and lay them on a flat surface to dry. The landing gear struts are the square 2.5mm x
1.5mm x 20cm long pieces of carbon.
Light-weight control horns and servo arm extenders are included in the kit and can be cut out and prepared
for use later.
.
Work on a flat surface and glue the horizontal airframe parts together as shown below. Allow the glue some
time to become tack dry before bringing the various parts together. Leave on a flat surface and allow to dry
Glue in the wing bracing strips as shown. Note that the U shape gap in the brace must be turned up to allow
the carbon support rod to fit in.
Glue in the carbon brace rod using either foam safe glue or Araldite. Allow to dry on a flat surface.
Weights can be put on carbon rod to hold it firmly in the slot.
While the airframe is on the flat surface you may glue on the first lower section of the vertical airframe. As
you will need to push the lugs into the slots, it is important not to let the glue become tac dry before you bring
the parts together. This will allow the parts to slide together and in place easily.
Landing gear struts can now be glued in place. With the airframe on a flat surface, measure the height of the
axel on either side to ensure they are the same height. Take particular note of the arrows on the horizontal
airframe which indicate which wheel strut goes at the front and which goes at the rear.
The images below show for each model type where the carbon rod bracing should attach. Refer to the
lengths indicated and cut the supplied carbon rods to size. With the airframe still on the flat surface, attach
the carbon rods to the under-side of the airframe.
Carbon Rod Guide
Wing Spar – 3.0mm x 3.0mm square x 78cm long (one piece)
Aileron Pushrods – 1.5mm round x 15cm long (two pieces)
Elevator and Rudder pushrods – 1.0mm round x 50cm long (two pieces)
Bracing – 1.0mm round x 80cm long (four pieces)
* This is enough bracing to cut up and use for all bracing with plenty left over for spares and repairs.
* Landing gear carbon lengths are not pictured below.

Servos can then be mounted and glued in place.
A piece of spare carbon can be cut and glued to the bottom of the vertical stabilizer to act as a ground skid.
The top part of the vertical airframe can then be glued and fixed to the lower half.
The final carbon struts can then be fitted as shown below.
This kit contains a fit-out kit for control linkages. The various knuckle joints, control horns and motor mount
can now be attached as shown below.
Drill holes in the motor mount to suit your chosen motor and attach the motor.
Use the double sided hook and loop tape supplied in the kit to attach ESC units and receiver. Keep these units
as close to the centre as possible and try to balance the weight evenly from left to right.
The supplied pushrod connectors can be attached to the carbon rods with the pieces of heat shrink. Use heat
to shrink the heat shrink firmly around the pushrod and control linkage.
Optionally, the control linkages may be glued to the carbon rods and bound with twine for strength.
The image below shows the control linkage set up with the servo extender arms which give the control
surfaces more throw. Note that the carbon rods for the ailerons are the thicker 1.5mm diameter ones.
Left: Thread the pushrod guides on to the pushrod and space them evenly along the airframe.
Right: The completed aileron control linkage attached to the servo with the extensions in place.
At this point you will need to set up and test your radio gear and make sure all servos have the correct
direction of travel. Set all transmitter trims to neutral and trim the carbon pushrod as necessary before fitting
the Z-bend linkage.
Use a peg or clip to keep the vertical stabilizer control surface in line and heat shrink the Z-bend and carbon
pushrod together.
Glue the pushrod guides in place.
For the ailerons, start by using a clip keep the aileron surfaces aligned with the wing, and then simply screw
the knuckle joint connector tight. Be careful not to over tighten the screw as it will completely crush the
carbon rod.
Trim off the excess carbon rod from the aileron surface joint and add the strengthening ribs to each wing.
The air-dams can then be installed on each wing and glued in place.
The landing gear comes with fairing supports which can be glued to the carbon axel. You can then glue the
wheel covers to this fairing. Be sure to allow enough play for the wheel to turn freely and don’t get glue on
the part of the axel where wheel is.
Your choice of prop saver and propeller can now be attached. Any leftover hook and loop can also be used to
attach the battery. Try to keep the battery as close to the centerline as possible so as to avoid uneven eight
distribution.
