5. Repeat the procedure to install a 105mm long carbon

rod next.

same procedure.

7. Turn the plane upright. Install the two 130mm carbon

rods and brace doublers between the vertical fi n and stabilizer.

ADJUST THE PUSHRODS

1. With the transmitter and receiver switched on and the

elevator servo centered, make sure that the elevator control
horn is seated against the elevator. Check that the elevators
are centered. If they are not, you will need to adjust the length
of the z-bend.

PUSHROD LENGTH ADJUSTMENT

For your convenience,
the aileron and elevator
pushrods have been pre-
assembled. If you are not
using a Futaba S3114
servo, or due to manufac-
turing tolerances, it may
be necessary to change
the pushrod length. This
may be done by holding
the heat shrink tubing that
connects the pushrod to
the z-bend and gently ro-
tating the z-bend until the
glue holding the z-bend
breaks loose. Then, adjust
the length by pulling or
pushing the z-bend until
the appropriate length is
achieved. Re-glue the z-
bend to the pushrod using
a drop of thin CA. Be care-
ful that the CA does not
run down the pushrod and
into the pushrod guides.

2. Once the elevator is centered, apply a bead of foam-

safe CA along the joint between the elevator control horn
and the elevator.

3. Use foam-safe CA to glue the rudder control horn to

the rudder.

4. Adjust the length of the pushrod so that when the rudder

servo is centered, the rudder is centered.

5. Apply a drop of thin CA to the end of the heat shrink

to further secure the z-bend to the pushrod.

6. Operate the rudder and elevator, checking that the

pushrods do not bind in the pushrod guides. Adjust the position
