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
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 over an unsafe area, such as a road or street.
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.

Page 2: Required Items
Always obtain proper insurance before flying – contact the AMA at www.modelaircraft.org REQUIRED ITEMS CA Glue – Thin and Medium CA accelerator and debonder Hobby Knife Set Metric Allen Wrenches Phillips screwdriver Scissors Small Pliers Wire Cutters Rubbing alcohol Paper towel Optional –... - Page 3 Attach landing gear to fuselage using two 3mm allen-head screws (the two shortest screws in your kit). Use blue Loctite on these screws. Attach landing gear cover plate. For permanent installation, use medium CA glue. To be able to easily access landing gear screws, use clear tape to attach plate.
- Page 4 Place wheel on aluminum wheel axle and install aluminum wheel collar, using a 1.5mm allen wrench to tighten the set screw. Place wheel and axle assembly inside wheel pant. Attach wheel/pant assembly to carbon landing gear as shown using locking nut. NOTE: The locking nut will be difficult to tighten since it is a locking design. Use a pliers to hold the wheel collar and a nut driver or wrench to turn the nut.
- Page 5 Remove one square of covering from the fuselage bottom behind the wing as shown, for a cooling vent. Remove covering over wing spar hole, wing bolt hole, aileron wire hole, and anti-rotation pin hole as shown in side of fuselage on both sides.
- Page 6 Remove the covering over the horizontal stabilizer opening and servo opening on both sides of the fuselage as shown. Trim rear section of stabilizer opening to ensure good clearance for elevator joiner.
- Page 7 Insert horizontal stabilizer (note the color scheme on top). Use a ruler to square the stabilizer side to side as shown. Insert carbon wing tube into fuselage. Measure from tube to horizontal stabilizer on both sides of fuselage. Equalize measurements to square the stabilizer.
- Page 8 Drip thin CA glue into the stabilizer-fuselage joint. Do not remove any covering from the horizontal stabilizer. Apply medium CA into the slot in fuselage and install vertical stabilizer. Drop a few drops of thin CA onto the elevator joiner rod at the factory joint of elevator and rod. Allow to soak in for a few minutes, then wipe off excess.
- Page 9 Install elevator half with joiner rod onto horizontal stabilizer, sliding hinges into slots in stabilizer DO NOT GLUE HINGES YET. Apply a generous amount of medium CA into joiner slot on second elevator. Install second elevator onto elevator joiner rod and slide hinges into stabilizer. DO NOT GLUE HINGES YET.
- Page 10 Apply two large drops of thin CA glue to each elevator hinge. Allow to soak in and cure. Do not use any accelerator on this glue, allow the glue to fully soak in. Remove covering over slot in bottom of rudder as shown.
- Page 11 Use small drill bit, small screwdriver, or end of tailwheel wire to make a hole in the rudder at the appropriate spot and insert tailwheel wire into rudder. Check location against manual photo, and if the wire is in the correct location, remove and put a generous amount of medium CA glue into slot. Install wire and allow to cure.
- Page 12 Install tailwheel bracket with two small wood screws. Check for free swinging of rudder. Adjust bracket as necessary to allow rudder to swing freely. Install tailwheel and tighten tailwheel collar with 1.5mm allen wrench. Locate the 4 control horns in your kit. The two on the right are for the elevator and rudder. The longer horns on the left are for the ailerons.
- Page 13 Pushrod connectors – The pushrod connectors attach to the servo arm with a nut, as shown. When you install these pushrod connectors, do not tighten the nut all the way, the connector must be free to rotate. Place a drop of medium CA on the end of the nut and apply CA accelerator to lock it to the threads. You must lock the nuts on your servo connectors, otherwise the nuts will vibrate loose and your plane will crash.
- Page 14 Install elevator horn, servo, arm, and pushrod on the LEFT side of the aircraft using the same procedure as the rudder components. The elevator pushrod is the 2 longest in your kit. The elevator pushrod will require a slight bend near the servo for alignment. Assemble your brushless motor for mounting *in front of* the firewall (many brushless motors have more than one mounting option).
- Page 15 Install your receiver onto the receiver mount in the fuselage as shown using Velcro or a Zip-tie. The cowl mounts using 4 small wood screws which screw through the cowl into small plywood rectangles at the front of the fuselage. In order to know where to make the holes in the cowl for the screws, place tape strips on the fuselage over the plywood as shown.
- Page 16 Remove cowl, place a drop of thin CA glue into each hole in the fuselage, allow to cure, and re-install cowl with 4 small wood screws as shown. Align covering stripes on ailerons with stripes on wings. Apply two large drops of thin CA glue to each aileron hinge.
- Page 17 Remove covering over servo opening and aileron control horn slot as shown. Install aileron control horn as you installed the other horns. Use the installed pull-string to pull the servo wire through the wing.
- Page 18 Install the servo using the servo screws which come in the servo package. Install pushrods and servo arms as shown. Install SFG’s on each wingtip using the 4 large wood screws as shown. Attach wings to fuselage with nylon wing screws. NOTE – the carbon wing tube is designed to be removable, and is not meant to be glued in place.
- Page 19 Balancing: The recommended starting balance (CG) point of the 47” Extra is 3.5 inches behind the leading edge of the wing measured at the root of the wing, where the wing meets the fuselage. This is a conservative CG location, excellent for sport flying or precision flight. For 3D flying, you may wish to move your CG back.
- Page 20 After you have completed all of your radio setup, take the model outside and install your propeller. Test run your power system in a safe manner. Recommended power level for the Extra is 350-440 watts. NOTE: Small brushless motors typically have aluminum prop adaptors with aluminum screws threads. These threads are easily stripped or broken.
