Tips for Success:
1. Before starting assembly, take a few minutes to read the entire instruction manual
to familiarize yourself with the assembly process.
2. Note that this aircraft is covered using our printed covering technique. Your
aircraft has been sealed with a gloss clearcoat. Due to climate changes, wrinkles
may develop in the covering. These are easily removed with a little bit of heat. Use
your heat gun or a covering iron with a soft cotton iron sock, medium heat, and a
gentle technique. Just like regular covering, you can remove any wrinkles that
develop over the life of your aircraft, but go a little slower and be a bit more careful
for best results. Your iron will feel a bit different gliding over this sealed covering
than regular. Be careful not to use too much heat as the covering may shrink too
much and begin to lift at the edges. Take your time, and the beautiful glossy finish
can be easily maintained.
3. Apply a bead of Pacer Formula 560 Canopy Glue at the intersection of the plastic
canopy and its wooden frame.
4. Take a few minutes and apply CA to high stress areas such as servo mounting trays,
landing gear mounts, anti-rotation pins, and motor box joints.
5. By the time your aircraft arrives at your door step, it will have been handled by a lot
of people. Occasionally, there are small dings or imperfections on some of the
surfaces. An effective method to restore these imperfections to original condition is
to use a very fine tipped hypodermic needle and inject a drop of water under the
covering material and into the ding in the wood. Apply heat to the area with a
sealing iron and the imperfection will disappear. Deeper marks may require that
this process be repeated a couple of times to achieve the desired result, but you will
be surprised at how well this technique works.
6. Use a high quality epoxy for installing the composite control horns. We highly
recommend a 30 minute Epoxy or Pacer Z-poxy.
7. Take the time to properly balance and trim your aircraft and set up rates and
exponential values. Your flying experience will be greatly enhanced once your plane
is properly dialed in.
8. If you are using a light power system, such as a DA-35 engine or a 3000watt electric
system, certainly use the forward, pull-pull rudder servo location. If you are using a
heavy power system, such as a 50CC sized electric or a 50CC gas engine with a large
muffler, use the rear (push-pull) location. If your power system is mid-sized, feel
free to wait until AFTER checking the balance of the model before deciding.

NOTE: Some photos in this manual use another of our aircraft, but all of our 50cc sized
aerobatic aircraft assemble nearly identically.
Let's begin!
1. Locate the 2 wing panels and the aileron control hardware as shown. Use a
soldering iron or sharp hobby blade to remove the covering over the servo opening
and the slots for the aileron horn. Make sure you are doing this on the bottom of
the aileron!

6
2. Use sandpaper to scuff the portion of the horn that will be inserted into the control
surface. Do this for all control horns on your aircraft before installing them.
3. Locate the square control horn plate, and assemble the horn as shown. Insert into the
aileron without glue, and use the plate as a guide to cut the covering around the plate.
Remove this covering.

7
4. Using 30-minute epoxy, glue to the horn into the surface, making sure the screw holes
are lined up with each other. Wipe up any excess epoxy, and clean up with denatured
alcohol. Repeat the entire process for the other wing half and allow both to dry.

8
5. Attach a 12” servo extension wire to the aileron servo, and make sure it is secured
with tape or heat shrink or a lock. Use the servo manufacturer supplied mounting
hardware to install the servo as shown. Electronically center the servo and install a
1.5" Extreme Flight servo arm as shown.
Assemble the pushrod by screwing the plastic/brass ball links onto the metal
pushrod and install with screws, washers and locknuts as shown. Repeat for the
other wing half.
Fuselage Assembly
8. Locate the landing gear hardware parts, as shown, as well as the carbon landing
gear, 2 main wheels, gear cuffs, and wheel pants.

9
Place the wheel on the axle and secure with the wheel collar, use a 1.5mm hex river to
tighten the collar set screw .
9. Attach the carbon landing gear to the fuselage. The screws are installed into the
fuselage for shipping, remove them first. Use Loctite thread-locking compound on
these screws when you install them.

10
Using epoxy or rubber cement, attach the gear cover plate as shown.
10. Locate the gear cuffs. Slide them up the gear legs to the fuselage, place a dollop of
rubber cement inside the gear cuff to glue the cuff to the carbon gear leg. Screw the
cuff to the gear with wood screws as shown. Allow to dry.

11
11. Insert the wheel and axle into the wheel pant. Place the threaded portion of the
axle through the hole in the landing gear and screw the locking nut onto the axle,
making sure the wheel pant is positioned properly. Use the included metal wrench to
hold the axle as shown, and tighten the nut securely.
12. Locate rudder hardware as shown.

12
Scuff center of rudder control horns with sandpaper, remove a covering square under
plate as you did for the aileron horns, and glue into rudder with epoxy as shown.
Make sure rudder horn is centered in the rudder, side to side. Allow to cure.
Note: The same horn is used for either front-mounted pull-pull rudder or rear-mounted push-pull rudder control.

13
13. While the rudder horn cures, install the tailwheel as shown, using thread-locking
compound on the screws.
14. The rudder on the 79" Slick 580 is removable for transport, held in place by a steel
wire pin which runs the entire height of the rudder. Locate this wire pin and lube it
with silicone spray lube or another plastic-safe lube. Align the rudder hinge halves and
insert the pin from the top of the rudder. NOTE: This pin must be a snug fit for your
rudder action to be precise. Take your time inserting the pin the first time.

14
15. Locate elevator hardware as shown.
Install elevator horns as shown, using the same technique as the previous horns.

15
16. Attach a 36" servo wire extension to your elevator servos, use a plastic lock or tape
to make sure the wire connection cannot come loose in flight. Feed the wires through
the tube in the fuselage as shown. Install the elevator servos as shown using the
mounting hardware included with your servos. Center your servos and install 2.0"
servo arms as shown.

16
17. Locate the carbon spar tube for the horizontal stabilizers/elevators. Insert the tube
into the fuselage and slide the stabs/elevators on. Secure with screws and washers.
NOTE: If you intend the remove your stabs for transport, don't Loctite these screws. If
you intend the stabs to be permanent, use Loctite. Install servo arms and pushrods as
shown with washers, screws, and locking nuts.
18. Locate the firewall drilling template correct for your engine if using gasoline.
Locate the engine and cowl hardware as shown.

17
Place the firewall drilling template over the firewall and drill the four holes for engine
mounting, and the additional holes you need for your installation. Most installations
will not use a choke servo, and so do not need the hole for the choke pushrod.

18
19. Mount your engine as indicated by the manufacturer. To determine the exact
length of standoffs and shims you need, place the cowl on the airplane and measure as
shown to the firewall, and subtract the length of your engine. For a DA-50, a 2.5 inch
standoff is needed.
20. Mount the throttle servo. In general, this servo is intended to be mounted inside the
motor box as shown, but this may be different on some engines to get the best path for
the throttle pushrod. NOTE: In our testing, we used mini servos on throttle.

19
21. Mount your fuel tank (we recommend the Extreme Flight Flowmaster 14 oz. or
17oz. tank) and run the lines, mount your fuel filler in the fuselage as shown.
22. Test-fit your cowl onto the fuselage. You will need to cut your cowl to fit around the
cylinder head of your engine if you are using a single-cylinder engine, and for any
additional cooling desired. We use a dremel rotary tool with a sanding drum
attachment for this job. Be sure to protect your skin and eyes when cutting or grinding
fiberglass. Go slow, making small cuts, until the cowl fits over the cylinder.

20
23. Once you are satisfied with the fit of your cowl, make sure any equipment under the
cowl (ignition, any lines, throttle or choke linkage hardware) is installed properly and
well-restrained, and prepare to install the cowl. Cut and place pieces of tape as shown
to indicate the location of the cowl retention nuts in the fuselage.
Peel the tips of these pieces of tape back as shown.
