SAFETY in Assembly
During assembly of this aircraft, you will be asked to use sharp knives and hobby adhesives. Please
follow all safety procedures recommended by the manufacturers of the products you use, and always
follow these important guidelines:
ALWAYS protect your eyes when working with adhesives, knives, or tools, especially power tools. Safety
glasses are the best way to protect your eyes.
ALWAYS protect your body, especially your hands and fingers when using adhesives, knives, or tools,
especially power tools. Do not cut toward exposed skin with hobby knives. Do not place hobby knives on
tables or benches where they can roll off or be knocked off.
ALWAYS have a first-aid kit handy when working with adhesives, knives, or tools, especially power tools.
ALWAYS keep hobby equipment and supplies out of the reach of children.
IMPORTANT NOTE – We strive to provide the absolute best-quality ARF aircraft on the planet. However,
the ultimate success or failure of this aircraft is dependent upon proper assembly by you. If you have
questions about an assembly step, please contact us, or read the assembly thread for your airplane on
RCGroups.com before proceeding. It is always better to slow down and be sure of your assembly than to
rush through it and make a mistake which can cause a crash.
SAFETY in Flying
SAFETY NOTICE: This is NOT a toy! It is a very high-performance RC airplane capable of high speeds
and extreme maneuvers. It should only be operated by a competent pilot in a safe area with proper
supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly.
NEVER fly near overhead power or utility lines. If your airplane ever becomes stuck in a line or a tree DO
NOT attempt to retrieve it yourself. Contact the authorities for assistance in retrieving your aircraft.
Power lines are DANGEROUS and falls from ladders and trees CAN KILL!
Never fly too close to yourself or spectators. Spinning propellers are DANGEROUS!
Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.
Always fly within your control.
Always follow manufacturer's instructions for your radio system.
Always obtain proper insurance before flying – contact the AMA at

Page 2: Required Items
REQUIRED ITEMS CA Glue – Thin and Medium or Thick Hobby Knife Small Phillips Screwdriver Set Metric Allen Wrenches Scissors Small Pliers Adjustable wrench Masking tape Drill and drill bits Optional – Heat gun and covering iron Threadlocker (Blue Loctite) Polyurethane or 30min epoxy glue Vaseline/petroleum jelly Rubbing alcohol... - Page 3 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.
- Page 4 Install wood screws through gear into pants as shown Attach the gear to the fuselage with 4-40 screws, use loctite. Install gear cover plate as shown, using thick CA or epoxy glue.
- Page 5 Install tailwheel onto fuselage as shown, using QTY 2 4-40 screws and washers, with loctite. Remove the covering over the pre-fabricated cooling holes in the bottom of the fuselage, as shown. HINGING The 70” slick comes with pre-hinged and pre-gap-sealed wings/ailerons to save time during your build. You will need to hinge the tail.
- Page 6 Remove the hinges from the tail surfaces. Use a q-tip to apply Vaseline to the center area of the hinge. We do this to keep glue out of the rotating part of the hinge. We use Vaseline, instead of oil, so that we can contain the Vaseline to only the center part of the hinge.
- Page 7 Insert the rudder onto the hinges and tail-wheel tiller wire as shown. Swing the rudder back and forth several times to make sure it swings easily 45 degrees each way. Clean any glue which seeps out of the hinges and allow to dry. If using polyurethane glue, you may see more glue seeping out as it dries. Wipe this away with alcohol.
- Page 8 Using plenty of epoxy or polyurethane glue, install the rudder horns as shown, on both sides of the rudder. Use the ball-joint and pull-cable end, as shown, to hold the rudder horn in perfect alignment while the glue dries. Clean up any excess glue with alcohol. Allow to dry. A NOTE about servo arms on the 70”...
- Page 9 Install the rudder servo, servo arm, and ball links with locking nuts as shown. The rudder pull-pull cables are assembled as shown in the diagram. Crimp the crimp tubes firmly with pliers, and use a drop of thin CA glue on each crimp tube after you are done crimping. Crimp the servo end of the cables first.
- Page 10 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.
- Page 11 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.
- Page 12 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.
- Page 13 Before installing the elevator with the slot which accepts the joiner, practice fitting it once, the joiner is very tight in the slot. Use plenty of polyurethane or epoxy glue in the slot, and install the elevator. Make sure it can swing freely at least 45 degrees up and down. Allow to dry.
- Page 14 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. The firewall of the Slick is arranged to allow the widest possible selection of motors to fit. Extra space has been provided for long motors and long prop adaptors.
- Page 15 Cut small strips of paper or card stock and use masking tape to affix them to the fuselage as shown, to indicate the exact location of the four cowl-mounting tabs which extend forward form the fuselage. Install the cowl, and use the paper strips as guides to make holes in the cowl over the tabs. You can use a twisting motion with your hobby knife to start these holes.
- Page 16 Remove the covering over the aileron servo openings and the aileron control horn slots as shown. Use epoxy or polyurethane glue to install the aileron horns into each wing as shown.
- Page 17 Attach servo extensions to aileron servos. Use the string installed in the wing to pull the servo wire through the wing, then install the servo into the wing as shown. Assemble the aileron pushrod as shown and attach the pushrod to the servo arms and aileron horn with black allen-head screws and lock nuts. Apply one side of the self-adhesive Velcro tape to the battery tray, the other to your battery.
- Page 18 Balancing: The AJ Slick can use a wide range of center-of-gravity locations. For your maiden, we suggest a more forward CG location, since you can always move your CG rearward to suit your flying style if necessary. For maiden and precision flight - 155-160mm from leading edge of wing at root This is approximately the forward edge of the carbon wing spar tube.
