Wing

 

 

The  wing  consists  of  three  panels:  the  centre  section,  which  is  screwed  to  the  fuselage,  and  the 
two outboard panels, which plug into the centre section. All the wing panels are of traditional built-
up construction and are supplied assembled and film-covered. The ailerons and camber-changing 
flaps are already hinged, and the facing ribs at the dihedral breaks are correctly angled. 

 

The centre section is fixed to the fuselage by means of a central screw. Melt the covering film over 
the  screw-hole  using  the  tip  of  a  hot  soldering  iron;  the  heat  in  the  tip  will  immediately  glue  the 
surrounding film down again. A locating peg has to be glued in the leading edge of the wing; mark 
the position of the hole in the fuselage on the leading edge before drilling the hole for the peg. 
 

 

Open up the servo wells using a small soldering iron. 

 

The  aileron  and  flap  servos  are  installed  using  the  servo  mounts  supplied.  To  determine  their 
exact position, push the mounts onto the servo, and place 

this assembly in the servo well “dry” (no 

glue). Mark the exact position where the mounts are to be installed. 

 

Glue the servo mounts in the wing using thick cyano or 5-minute epoxy. Allow the glue to set hard. 

 

Check  that  the  servo  output  arms  are  exactly  at  right-angles  to  the  hinge  pivot  axis,  then  fix  the 
servos in the mounts using hot-melt adhesive. 

 

 

Cut off the connector end of the servo leads. For each servo draw a twisted extension cable (not 
included in the kit) through the wing panels. You will need to fit three-pin plugs and sockets at the 
transition point between the centre section and the outboard wing panels. 

 

Solder  the  twisted  extension  cables  to  the  servo  leads,  and  fit  a  heat-shrink  sleeve  over  each 
soldered  joint  for  additional  protection.  An  alternative  is  to  install  extension  leads  terminating  in 
sockets,  and  connect  the  servo  plugs  to  them.  In  this  case  you  do  not  need  to  cut  off  the  servo 
leads,  but  the  connectors  must  be  secured  with  adhesive  tape  to  avoid  any  danger  of  them 
working loose. 

 

A six-pin plug and socket connection  is required at the transition from the  wing centre section to 
the fuselage. Note that all the positive servo wires can be soldered to a common pin, as can the 
negative wires. 

 

Connect the radio control system, and check the operation of the installed servos from the trans-
mitter. At this point you can also check the servo neutral positions, and set the correct directions of 
rotation. 
 

 

Glue  the  horns  in  the  flaps  and  ailerons  prior  to  installing  the  linkages;  the  horns  must  line  up 
accurately with the servo output arms. 

 

The short horns are intended for the ailerons; the linkage hole should be located exactly over the 
aileron hinge pivot axis.

 

Glue the longer horns in the flaps, as described for the ailerons. 

 

The linkages themselves are each assembled from a pre-formed wire pushrod, a threaded coupler 
and  a  plastic  clevis.  Take  care  to  produce  sound  soldered  joints  between  the  threaded  couplers 
and the rods. Epoxy can be used as an alternative. 
 

 

Carefully cut out the servo well covers and fix them to the wings using clear adhesive tape, after 
checking that the servo output arms do not foul the inside of the well covers when they deflect. 
 

 

Join the wing panels using the CFRP / GRP joiner rods. Note that the joiners incorporate the cor-
rect dihedral. 

 

Glue the incidence pegs in the outboard panels to prevent them rotating on the joiner rods. Leave 
about 10 mm projecting, and sand the exposed ends to a rounded profile. 

 

The outboard panels are held in place by strips of adhesive tape applied to the top surface of the 
wing along the separation line. 

Tailplane

 

 

The tailplane is screwed to the tail end of the fuselage, and can be removed for ease of transport. 

 

Use  a  soldering  iron  to remove  the  covering  film  over  the  central  hole  in  the  tailplane,  then  glue 
the metal captive nut in the hole from above (!) using 5-minute epoxy. It is a good idea to remove 
a little more film all round the hole, to achieve as strong a glued joint as possible. 

 

The  top  surface  of  the  tailplane  is  that  to  which  the  elevator  is  attached  using  an  adhesive  tape 
hinge.
