●First-time builders should seek advice from people having building experience
in order to assemble the model correctly and to produce its Performance to full
extent.
●Assemble this kit only in places out of children’s reach!
●Take enough safety percautions prior to operating this model. You are
responsible for this model’s assembly and safe operation!
●Always keep this instruction manual ready at hand for quick reference,even
after completing the assembly.

Install the wheels onto the axles and secure with the wheel collars, as shown.
Slide one wheel/axle assembly into a wheel pant, and install the wheel assembly on the landing gear leg. Tighten
the locknut as shown to secure the assembly onto the gear leg. Repeat for other side.

Attach the gear to the fuselage with short 3mm screws, use loctite.
Install gear cover plate as shown, with clear tape, thick CA or epoxy glue.
Remove covering over horizontal stabilizer slot on both sides of fuselage as shown. Remove covering over elevator
servo opening on LEFT side of the fuselage as shown.

Remove covering over wing spar tube hole and wing pin holes in fuselage as shown.
Install rudder onto fuselage and apply 2 large drops of thin CA to each hinge.
Remove covering over control horn slot in rudder. Install double-sided rudder control horn as shown with plenty of
medium or thick CA, or epoxy glue. Install tail wheel as shown with two small wood screws. Remove the set screws
in the tailwheel assembly and re-install with blue loctite.

Use a ruler to align the stab side-to-side.
Using a tape measure or long ruler, measure from the stab to the wing tips as shown
in the diagram. Equalize that measurement right and left to be sure your stab is
aligned.

When stabilizer is centered and aligned, drip Thin CA glue onto the stab-to-fuselage joint top and bottom. NOTE: We
do not remove any covering form the horizontal stabilizer. This keeps the stabilizer strong, and thin CA makes an
excellent joint to covering material. If your stab joint is not tight enough for thin CA glue, or if you have to trim the
opening to align the stab, you can use thick CA glue as well.
Install the elevator half with the fiberglass joiner rod onto the stabilizer. Makes sure it flexes easily at least 45
degrees up and 45 degrees down. Apply thin CA glue to the hinges, 2 large drops on each.

Place a generous amount of medium or thick CA into the joiner slot on the remaining elevator, and slide the elevator
into place on the stabilizer. Make sure it is aligned and flexes easily at least 45 degrees up and down. Glue the
hinges with thin CA.

Use a lock nut to tighten the ball link into the rudder control horn. Assemble the cables onto the pull-wire ends,
pulling the cables snug before crimping. We do not need the cables to be extremely tight, just snug and without
sagging. Use the threaded pull-cable ends, screwing them into the ball joints as necessary, to tighten the cables
Install elevator servo with servo output spline toward front of plane and install arm and tighten pushrod connector.
The rudder pull-pull cables are assembled as shown in the above diagram.

Assemble the pull-pull wires onto the rudder horn as shown, double-looping the wire through the brass crimp sleeve
before crimping. Crimp the brass crimp sleeve tightly with pliers and apply a drop of thin CA to the crimp. Be SURE
to use medium or thick CA to lock the 2mm nuts on the rudder control horn. Feed the wires into the fuselage slots
and forward to the front of the fuselage. Cross the wires once so they make an X inside the fuselage.
Mount the rudder servo and assemble the connectors onto the rudder servo arm as shown. Note that the connectors
must be free to rotate on the servo arm.
NOTE: The firewall of the Slick is pre-drilled for popular motor types. If your motor uses a different bolt pattern, mark
and drill the firewall as shown.

Attach the motor using the provided 4mm screws and blind nuts. Use loctite on the mounting bolts. Mount the
speed control to the side of the motor box as shown using Velcro and/or Zip ties.
Install the canopy hatch (if the canopy hatch is not installed when you fit the cowl, it may be impossible to
fit the canopy hatch after the cowl is installed!).
When you are satisfied with the cowl fit, tape the cowl to the fuselage with masking tape. Use the small pieces of
paper as guides to make holes in the cowl and install the wood screws. Remove the screws and cowl, and soak the
plywood mounting tabs in the fuselage with thin CA to harden them. Re-install cowl and screws.

Glue the aileron hinges with two large drops of CA per hinge.

Balancing – Balance your Extra 108mm behind the leading edge of the wing
where the wing meets the fuselage for your maiden flight. This is approximately
on the forward edge of the carbon wing spar tube. Move the flight battery to
balance as necessary.
Our preferred CG for 3D aerobatic flight is 120-125mm. This is approximately
on the rear edge of the carbon wing spar tube.
When you experiment with CG location, move the CG only small amounts, 1/8
inch or so, at a time. A small change in CG can have a large effect on flight
characteristics.
