3)  Aileron

• Bevel the front edge of the aileron at a 45 degree angle
• Using a strip of tape along the top surface, hinge the aileron to the wing using   e.g. using "3M 
Blenderm" tape,  or "Tixo ®" tape
• Clear an area of the building board for the wing

END  Page 4 of 12

• On the building board, fold the aileron fully back at 180 degrees, and press down
• Add three ~4 cm long strips of tape on the bottom of the aileron hinge at right angles to the hinge 
line / direction of flight -as a "backup hinge"
• Check that there is full movement of the control surfaces !

Tip: With appropriate construction experience, it is possible to make a "hinge" only using contact  
adhesive (UHU-Por ®) -using an already bevelled control surface applied close to the other  
surface, and then a thin film of adhesive is applied along the top surface.

4) Elevator

• Note that the elevator horn is glued between the two halves of the elevator !  -The required width 
(thickness of horn) is identified on the printing!
• The two elevator halves are joined with a short piece of flat carbon (found in the accessories bag) 
-note the gap between the two halves must be correct  -the best elevators will come from making 
sure that you have the correct width for the elevator horn !
• Bevel the front edge of the elevator and hinge to the tailplane using tape,  as you did for the 
aileron

Figure 6:   applying tape to make the aileron hinge

END  Page 5 of 12

•  Do NOT glue the rudder control horn yet !

5)  Attaching the fuselage horizontal piece and tailplane / elevator

• With everything flat on the building board (without the front fuselage part) assemble these parts 
with UHU-Por ® glue - leave this to dry.
• Be sure to avoid sticking to the building board  !

6)  Separating the top and bottom fuselage halves

• Separate the two fuselage halves carefully at the junctions using a sharp knife - do not pull them 
apart or break!

7)  Attaching the lower fuselage part

• Place the wing / fuselage / tailplane elevator assembly "upside down" on the building board
