72.

 

Apply masking tape to hold each aileron aligned with its adjoining wing panel. 

73.

 

Select servo output arms long enough to extend fully beyond the 
outer surface of the aileron hatch covers as shown at the right.   

74.

 

Attach an EZ Link connector to the outermost hole in each servo 
output arm. 

75.

 

Use the hardware provided with your servos to attach the output 
arms (and their EZ Link connectors) to your aileron servos. 

76.

 

Position the aileron hatch covers with their servos over the servo 
bays as pictured at the right. Use glue or screws to secure the 
hatch covers to their wing panels. 

77.

 

Insert an aileron pushrod into each EZ Link connector. „Point‟ the free end 
of each pushrod toward the trailing edge of its wing panel. 

78.

 

Using the pushrods as your guide, mark and drill holes in the ailerons to 
install the aileron control horn assemblies. (NOTE: Actual hardware 
supplied for control horns may vary from that shown at the right.) 

79.

 

Thread a clevis onto each aileron‟s pushrod and attach these clevises to the   
aileron‟s control horns. Remove the   
masking tape from the ailerons. 
(NOTE: Once you have adjusted the   
ailerons, coat each clevis and pushrod   
with epoxy to securely and safely affix   
each clevis to its rod; also, as a safety   
precaution, check each clevis before   
and after each flight.) 

80.

 

Guide the 2 identical ends of a 12-inch 
Y-harness out through the openings on 
each side of the fuselage as shown at the 
right. Connect its servo-like connector 
to your receiver‟s aileron port.   
(NOTE: If necessary, attach a servo 
extension to the Y-harness‟ servo-like connector to reach your receiver‟s aileron port.) 

81.

 

As shown below, use wood screws to attach 2 wing wire anchor points to the bottom of each top wing panel‟s center 
section. (NOTE: Harden these screw openings with thin CA adhesive.) 
 
 
 
 
 
 
 

82.

 

Use 

9/16

-inch (15mm) wood screws to attach the cabane struts to the bottom of the top wing‟s center section.   

(NOTE: Position the longer cabane struts toward the front and the shorter cabane struts toward the rear.) 

83.

 

Slide the top wing‟s composite wing rods into their openings and midway through the top wing‟s center 
section. Slide the top wing panels onto their wing rods. (NOTE: Carefully guide the Maxlok tabs at the root 
ribs into their matching slots in the top wing‟s center section.) 

84.

 

Insert the 2 shorter Maxlok pins into their openings in the bottom of the top wing‟s center section. 

85.

 

Test fit the lower ends of the cabane struts into their openings on 
each side of the fuselage. Align the carbon-fiber rods in the top 
wing‟s center with the lower wing‟s carbon fiber rod and with the 
horizontal stabilizer. (NOTE: If desired, at this time the angle of the 
top wing may be set to 0 degrees relative to the lower wing and the 
horizontal stabilizer by „fine tuning‟ the position of the cabane   
struts on the sides of the fuselage.)
