Step 8. 

 

   Firmly press the wing deck assemblies together. 

Use 

two large books to hold the pieces together flat against 
the table. Again, be careful not to glue the assembly to the 
table

Don’t remove books until glue is set.  

 

Step 9. 

 

   Locate the channels cut into the right and left aft 
fuselage pieces. These channels will be installed to the out 
side.

 The channel is represented by the dark area in the 

above picture.  

   

 

 

   Test fit the aft fuselage pieces into place. They should 
fit as pictured above. Don’t apply glue to the 1 inch by ½ 
inch servo slots. Glue the aft fuselage pieces into place. 
Use two large books to hold the wing deck assembly flat 
against the table as shown above

. This is very important.  

If not used the deck could warp. Don’t remove books until 
glue is set.

 

 

 
 

 
 
 

 
 
Step 10.  

 

   

Use the X-ACTO knife to cut 2 separate ½ inch long slots in the end 

of the access door opposite of the round hole. Then install fiber hinges. 

Do not glue

Take your time. Make sure the cuts are parallel to the edge 

as seen in the lower portion of the above picture.   
 
 

Step 11. 

 

   Mark the location each hinge contacts the belly plate As show. Then 
continue on next page. 

Note the location of the small hole in the door,. It 

should face aft as shown in the above picture.

  

 
 

 

   Cut the two separate ½ slots for the opposite end of the fiber hinges. 
Now slip the fiber hinges into the belly plate slots to complete the step. 

Do not glue the fiber hinges to the belly plate

. Only glue the fiber 

hinges to the access door so the door can be completely removed for 
access to the battery and electronics. Add a small drop of glue to the tip 
of the fiber hinges and then slid them into the ½ inch slots. Remove the 
access door for the next few steps.
