A QUICK WORD ABOUT SAFETY AND RADIO CONTROL FLYING MODELS
With radio control aircraft, like any hobby or sport, there are certain risks. The operator of these models is
responsible for these risks. If misused or abused, you may cause serious bodily injury and/or damage to
property. With this in mind, you will want to be certain that you build your model carefully and correctly. If
you are not an experienced flier, have your work checked and ask for help in learning to fly safely. This model
aircraft is not a toy and must be operated and flown in a safe manner at all times. Always perform a pre-flight
check of the model including all control surfaces, correct function of the radio gear, structure, radio range, and
any other area relating to the safe operation of this aircraft.
Models are not insurable but operators are. You can obtain coverage through membership in the Academy of
Model Aeronautics (AMA). For an AMA information package call 1-800-435-9262, ext. 292 or visit the AMA

Note: As with all kits, it’s a good idea to read all the instructions and study the parts before you begin
construction. Handle the parts of this kit with care so you do not damage any of the structure or covering.
Inspect all the parts for any shipping damage and report any issues to as soon as you can. Make sure you
have a flat and sturdy workbench and follow all safety advice for the tools and adhesives you plan to use.
AIRCRAFT COVERING
1. With all ARFs, varying temperatures and storage delays can cause covering material to loosen over time
and transportation. We recommend lightly going over all the covering with a covering iron set at medium
temperatures. Be sure to use a soft cover over your iron so you do not scratch the covering surface. Be
sure you go over all seams and edges of the covering to assure it is secure to the airframe and other
covering. Be careful not to apply too much heat or you may cause bubbles or damage to the covering. A
heat gun may also be used along with a soft cotton cloth to shrink and adhere the covering. Again, be
extremely careful when using a heat gun.
2. Be sure to seal any exposed wood with a thin coating of epoxy to prevent engine oil from soaking in. This
is especially important around the engine compartment and servo openings with exposed areas.
3. Some modelers prefer to seal the hinge gaps using strips of appropriate covering or clear trim tape. We
have found this to be helpful with models intended for higher speed flight or models with unusually large
hinge gaps. Our aircraft utilize a very tight double beveled hinge line and do not normally require this step.
Sealing the hinge gaps is therefore left as an option for the modeler.

RUDDER ASSEMBLY
NOTE: There are pictures of different planes in this manual, however, this plane’s rudder is assembled
the same way.
1．It is much easier to install the twin control horns before installing the rudder. Locate the carbon fiber
rudder control horns, ball links, and associated bolts and nylon-insert lock nuts. Use some fine sandpaper
to roughen up the center areas of the two control horns so that the glue adheres better. Using a sharp
hobby knife or soldering iron remove the covering away from the slots in the rudder and trial fit the two
control horns.
2. Mix up some 30 minute epoxy and coat the inside of the slots and the center of the control horns. Hint: a
scrap piece of 1/16” ply, tooth pick, or old hobby blade can be used to coat the inside of the rudder slots.
Slide the control horns in place and make sure they are centered perfectly by using a ruler to measure
between the pivot holes and the hinge line. Wipe any excess glue off with isopropyl alcohol and paper
towels. Install the ball links, bolts and nuts into the holes to help assure alignment of both control horns
while the glue cures. Set aside until cured. NOTE: There are pictures of different planes in this manual;
however, this plane’s rudder is assembled the same way.
3． Apply 30 minute epoxy to hinges, then insert them into the hinge slots on the rudder, secure the rudder
with masking tapes, then allow the epoxy to dry.

4. The EDGE can use either closed loop or a rear push pull servo for the rudder. We recommend that you
balance the model assembled before choosing your servo placement.
5. The SLICK is supplied with a high quality set of pull-pull cables and ball-links.
6. Install your rudder servo into the precut locations in the fuselage. Using a fine drill pre-drill the holes and
drop thin CA into the holes to strengthen the wood. You will need 3 inch arms on the servo. Set up your radio
accordingly and center the rudder servo.
7．Aluminum dual servo arm are include in the kit, enlarge the control holes with 2.5mm drill bit.

8. The EDGE has the closed loop pre-installed and crimped at the rudder end. These can be connected with
the M2.5 bolts and nut. The wire will be left looped inside the fuselage and will need to be connected to the
servo arm.
9. Use your radio system to center the rudder servo and attach either the supplied arm or an appropriate arm
for your servo. Thread one of the ball links about half way onto one of the threaded couplers. Feed the loose
end of one of the cables through a brass tube and then through the threaded coupler. Holding the rudder
centered, adjust the cable length as tight as possible while checking the ball link position over the servo arm.
When satisfied with the position, pinch the cable around the threaded coupler and then feed the loose end
back through the brass tube. Loop the cable back through the brass tube as before and crimp the brass tube
three times just tight enough not to cut the brass tube but enough to securely hold the wire in place. Cut off
the excess cable with wire cutters. Wick thin CA into the brass tube to help hold the cable secure. Repeat for
the other cable. Hint: Once you have established the position of the threaded coupler on the cable, you can
remove the ball link from the rudder horn to give you more working slack in the fuselage. Re-install the ball
link prior to setting the other cable.

10. Check the operation of the rudder using your radio and make sure there is no binding and the cables are
adjusted properly. You may have to tighten the cables after a few flights as they may stretch slightly from the
initial installation.
11．We recommend using KUZA 3.25” aluminium CNC servo arm (sold separately) for rudder control.
12．The SLICK also provides pull-push style for rudder. Below is picture of pull-push style linkage set.
13. Cut off excess carbon fiber rudder horn, and use sandpaper to rough the parts needed to inlay, and use
epoxy glue to glue the horn in place.

14. Use 2.5X110mm push rod between the servo and the rudder horn.
15. We recommend using KUZA 1.5” aluminium CNC servo arm (sold separately) for rudder control.
