V-tail shoulder 

The  carbonic  pins  must  be  ground  at  their  ends  with  help  of  a  turn-bench  and  so  their 

edges are flicked off. Those pins that will be sticked up in the fuselage must be roughened, 

so  the  pins  will  hold  to  fuselage  well.  We  glue  everything  with  the  epoxide.  Next  we  cut 

throught  the  holes  for the  butterfly-lever.  The  hole  is  marked  directly  on  the  fuselage.  We 

glue  the  enclosed  levers  into  the  butterfly.  The  lever  should  be  slipped  into  butterfly  as 

much as possible. We check the levers-position in fuselage after the glueing.

How to glue the butterfly´s servos 

We shorten the carbonic pull at the lenght 645mm and 630mm. We grind their ends again 

and  flick  off  the  edges.  We  flick  off  the  edges  of  threaded  rods  M2  too.  We  glue  the 

threaded rods M2 into both sides of carbonic pulls in the way so that approximately 10mm 

of the carbonic pulls sticks out the carbonic pipe. We screw the boll cups at one side.
