NOTE: Depending on the type of servo that you use, you may have to bend the pushrod slightly in the middle to angle it up 
from the wing so that it is aligned with the control horn without putting any bending force on the servo arm.

 
7.

 
Remove the pushrod from the servo 
and remove the solder link from the 
torque rod. Cut the pushrod at the mark. 
Slip the solder link onto the end of the 
pushrod so that the end of the rod 
extends 1/8" beyond the barrel on the 
link and solder into position, using 
enough heat to "sweat" the joint 
completely.

 

 

 
8.

 
Reattach the pushrod to the servo and the aileron torque rods. The aileron should be approximately neutral. Final 
adjustment will come later. Now fabricate and install the opposite pushrod assembly the same way.

 
 

FITTING THE WING TO THE FUSELAGE

For the following steps you will need:

The assembled wing 

The fuselage 

2 each 1/4-20 x 1-1/2" Nylon Wing Bolts 

1 each 3/8" x 12" Iron on Covering Strip 

 
1.

 
Now mount the wing onto the fuselage 
and install the nylon bolts through the 
wing and into the blind nuts installed in 
the fuselage. Now remove the wing and 
bolts form the fuselage.

 

 

 
2.

 
Take the 3/8" x 12" Iron-on Covering 
Strip and apply it to the bottom of the 
wing to cover the joint at the center of 
the wing.

The strip should start at the bottom of the finger at the leading edge and wrap around the trailing edge and ending on the 
top of the wing.

 
 

ASSEMBLING THE FUSELAGE

 

Preparing The Fuselage

 
For the following step you will need the fuselage. 
 
The fuselage has been built and covered but there may be several openings that must now be opened up. If these 
openings have not had the covering removed from them, you must use a sharp knife to cut away the covering from these 
areas.

Elevator & Rudder pushrod exits... 
Located below the stabilizer at rear of 
fuselage.

 

 

 
2.

 
Two screw holes for mounting landing 
gear... 
Located on the bottom of the fuselage 
just ahead of the wing opening.
