All the parts are pre-cut and some tabs have been left in to hold the parts in the sheets. Using a hobby knife, carefully cut through the tabs to remove the parts. First, insert the front part of the wing support through the slot in the horizontal fuselage section Slide the horizontal fuselage section over the front of the wing support and push it back into...

Then push the back part of the horizontal fuselage section down over the rear part of the wing support. Slide the whole horizontal fuselage section forward as far as it will go. Then lift up the rear part of the horizontal fuselage section and slot it down over the fin and work it down gently.

Insert the wings carefully, bit by bit into the wing shapers until they protrude about 2 cm. Optional Step: You can now insert the wings (with the shapers still on) into hot water to form the Depron to the shape of the curves. Briefly sand the inner parts which will be joined at about 10 degrees before gluing them so they fit together flush.

Both the tailplane and vertical stabiliser control surfaces are attached by a small section. Cut through this section to remove the control surfaces. These control surfaces will need to be cut or sanded at an angle as shown here to allow them to pivot freely.

Before gluing the undercarriage mount in place screw in the three positioning screws in place which hold the wire frame in place. Check the undercarriage is firm. Then glue the undercarriage in place. Glue in place the triangular support pieces as shown here.

If you are using a brick style receiver, (not included with kit) it can be mounted directly on top of the motor mount board. (MicronWings Receivers Link) Attach your control surfaces with hinge tape and ensure there is about ½ mm gap between the stabilizer surface and the control surface to allow for full movement.

Once again turn on your transmitter and check your servos are cantered. Use a piece of stiff masking tape or a pin to keep the control surface level and then trim the pushrod with plier cutters about 5mm from the control horn. Attach the control linkage with the hoop in it, add a little glue and heat to shrink the heat shrink to bond the join.

Next glue on the wings. If using UHU Expanded Polystyrene glue, apply a small amount to both surfaces and allow to dry till very tacky before bringing the two surfaces together. Check the wings are level. Use some modelling tape to pull the front and back down onto the pylon where the wings attach.
