4. Connect a servo extension wire or "Y" harness to

the right aileron servo. Install the right aileron servo in its

mount using the grommets, eyelets and screws provided

with your servo. Enlarge the mounting area as needed to fit

your servo. Note: Be sure to route the servo wire through

the hole in the wing and out the bottom of the wing.

5. Using the same technique you did with the elevator,

install the aileron control linkage.

In the following step you will glue the wing into place on the

fuselage. Normally, you would use a string or tape measure

to align the wing with the fuselage. This will not work with this

model as the foam fuselage easily flexes, making alignment

using that technique difficult. This is one case where the

TLAR method (That Looks About Right) works best. The

center ribs of the wing also help in its alignment. Sight the

model from above, making sure the wing is not cocked

sideways. Sight the model from the rear to make sure the

wing is parallel with the stab (see page 9, step 4).

Caution: You will need to use paper towels and alcohol to

clean up any excess epoxy, but be very careful doing so.

The alcohol can dissolve the paint on the fuselage,

causing it to streak. Use a dry paper towel to clean the

fuselage. Use another paper towel, lightly dampened in

alcohol, to clean the wing. Be careful not to touch the

damp paper towel to the fuselage.

6. Insert the wing into the fuselage and glue it into place.

It is best to use 30-minute epoxy as it allows time to adjust

the wing, but if you use 6-minute epoxy, practice aligning the

wing before gluing it into place. Be careful not to use any

excess epoxy as cleanup can be difficult. Note: To spread

the epoxy, slide the wing about 1/2" [12.7mm] so that it is

slightly off center. Spread some epoxy on the wood of the

exposed wing rib, on the top and bottom of the rib. Then,

slide the wing so that it is 1/2" [12.7mm] off center in the

other direction and spread some epoxy on the other

exposed rib. If you are careful not to use an excess amount

of epoxy, there will not be much to clean up. It does not take

a lot of epoxy to hold the wing securely in place.

7. After the epoxy cures, return to step 3 and install the

left aileron, servo and control linkage.

GET THE MODEL READY TO FLY

Check the Control Directions

For safety, remove the propeller from the motor. Move the

throttle stick to the off position (towards you.)

Warning: Whenever the model is not being flown or setup,

the battery should be disconnected.

1. Connect a charged battery to the speed control. Turn

on the transmitter, then follow the instructions that came with

your speed control to turn on the receiver. Center the trims on

the transmitter. If necessary, remove the servo arms from the

servos and reposition them so they are centered. Reinstall

the screws that hold on the servo arms.

2. With the transmitter and receiver still on, check all the

control surfaces to see if they are centered. If necessary,

adjust the Screw-lock connectors on the pushrods to center

the control surfaces.

3. Make certain that the control surfaces and motor

respond in the correct direction as shown in the diagram. If

any of the controls respond in the wrong direction, use the

servo reversing in the transmitter to reverse the servos

connected to those controls. Be certain the control surfaces

have remained centered. Adjust if necessary.
