Connect the ESC to the motor and secure it to the inside of the fuselage using hook and loop material.
4. Slide the cowling onto the fuselage. Install the propeller adapter onto the Outrunner shaft. You may need to ream out the hole on your prop hub to fit the prop adapter shaft at this point. Slide the propeller onto the prop adapter shaft. The spinner backplate and spacers may need to be enlarged as well to fit the prop adapter. Slide the spinner backplate and any needed spacers onto the prop adapter shaft. Secure the propeller using the prop adapter spinner and be sure it is secure and tight.
6. Enlarge the holes in the cowl using a 5/64" (2mm) drill bit. Secure the cowl using four 2mm x 8mm sheet metal screws. Snap the spinner cone onto the spinner backplate once the cowl is secure. Hint: Use thin CA to harden the holes drilled into the cowl mounting tabs. This will help to prevent the screws from vibrating loose in flight.
Aileron Hinging Required Parts Wing (left and right) Aileron (left and right) CA hinges (8) Required Tools and Adhesives T-pins Thin CA Drill Paper towel Drill bit: 1/16" (1.5mm) 20 1. Locate the positions for the hinges. Drill a 1/16" (2mm) hole in the center of each slot of both the wing and aileron. This creates a tunnel for the CA, allowing the CA to penetrate into the hinge better, bonding the hinges more securely.
2. Slide three hinges into the slits in the aileron. Center the slot in the hinge with the hole drilled in Step 1. Place a T-pin in each hinge to prevent it from being pushed into the wing when installing the aileron. 3. Slide the aileron into position. Check to make sure it can move without interference at the wing root and wing tip. Remove the T-pins and apply Thin CA to each hinge. Make sure the hinge is fully saturated with CA.
4. Firmly grasp the wing and aileron and gently pull on the aileron to ensure the hinges are secure and cannot be pulled apart. Use caution when gripping the wing and aileron to avoid crushing the structure. 5. Work the aileron up and down several times to work in the hinges and check for proper movement. 6. Repeat Steps 1 through 5 for the remaining aileron.

Attach a 6" (150mm) servo extension. Use string to secure the servo lead and extension to prevent them from unplugging in flight.
2. Place the servo in the wing. Guide the servo lead out through the opening at the wing root. 24 3. Secure the aileron servo using the screws provided with the servo.
4. Use a hobby knife to enlarge the inboard hole in the control horn to fit the 4" (100mm) long aileron pushrod wire. 6. Use 6-minute epoxy to attach the control horn to the aileron. Attach the control horns for both the right and left ailerons at this time. 5. Repeat Steps 1 through 4 for the other wing panel.
7. Attach the micro control connector to both servo arms. Be sure to use the included retainer to secure the micro control connector to the servo arms. Note: Use the long 3D servo arms included . with your servos to provide the greatest . amount of throw. 26 8. Turn on the radio system and center the aileron trim and stick. Make sure the aileron servo is operating properly using the transmitter. Slide the pushrod wire through the micro connector. Install the servo arm 90-degrees to the servo.
Wing Installation Required Parts Fuselage Wing (right and left) Wing tube #4 washer (silver) (2) 4-40 x 1/2" machine screw (2) Wing fairing (2) Fairing spring 2. Remove the hatch from the fuselage. Slide the wing panel with tube into position on the fuselage. Required Tools and Adhesives Hex wrench: 3/32" 6-minute epoxy Pliers 1. Slide the wing tube into a wing panel.
3. Slide the remaining wing panel into position. Secure the panels using 4-40 x 1/2" machine screws with #4 washers (silver) using a 3/32" hex wrench. 28 4. Test fit the wing fairing (filets) into position against the wing. You may need to loosen the screw holding the wing in place to install the fairing. Installing the fairing now will guarantee that it lines up correctly with the holes in the fuselage.
5. Use 6-minute epoxy to glue the fairing to the wing. Make sure not to get glue on the fuselage. Use tape to hold the fairing tight against the wing while the epoxy cures. 6. Repeat Steps 3 through 5 for the remaining wing panel and fairing. 7. Secure the fairings together inside the fuselage using the fairing spring and pliers. Note: The fairing may not fit tight against the fuselage at this time. This will be addressed once both fairings have been installed.
Stabilizer and Elevator Required Parts Fuselage w/wing installed Stabilizer Elevator CA hinge (4) Required Tools and Adhesives Hobby knife Felt-tipped pen Ruler T-pins Thin CA 1. Hinge the elevator and stabilizer, using the same process as described in Aileron Hinging. Use 6 hinges for this process. 30 2. Position the stabilizer into the slot in the aft end of the fuselage. Check that the elevators are an equal distance from the fuselage.
3. Measure from the stab tip to the wing tip. Adjust the stab until the measurements are equal. A 4. View the airframe from the rear and make sure the wing and stab are parallel. If not, lightly sand the stab saddle until they are.
5. Double-check the adjustments from Steps 1 through 3. Use a felt-tipped pen to trace the outline of the fuselage onto the top and bottom of the stabilizer. 6. Use a sharp hobby knife to cut the covering slightly inside the lines drawn. Be very careful not to cut into the underlying wood, as this will weaken the stab and cause it to fail in flight. Note: You can use a soldering iron instead of a knife. This will eliminate the chances of cutting into the wood.
7. Slide the stab and elevator back into position. Again, check the alignment and make sure everything lines up. Wick Thin CA into the joint between the fuselage and stabilizer. Make sure to glue both top and bottom. Do not use accelerator— to allow the CA to wick in as far as possible, providing the best bond possible.
Rudder and Fin Required Parts Fuselage Fin Rudder CA hinge (3) Required Tools and Adhesives Hobby knife Thin CA Felt-tipped pen Square 6-minute epoxy Medium grit sandpaper 1. Roughen the tail wheel assembly using medium grit sandpaper. Use 6-minute epoxy to glue the tail wheel assembly into the rudder. 2. Hinge the rudder and fin, using the same process as described in Aileron Hinging. Use 3 hinges for this process. 34 2. Place the fin in position on the fuselage.
3. Remove the covering from the bottom of the fin using the same technique used for the stabilizer. 4. Position the fin back onto the fuselage. Use a square to check the alignment between the fin and stabilizer. Lightly sand the bottom of the fin until the alignment is correct.
5. Use thin CA to glue the fin to the fuselage.
1. Secure a 18" (457mm) servo extension to the servo. Mount the elevator servo using the hardware provided with the servo. 3. Attach the micro control horn to the elevator using the control horn backplate and 6-minute epoxy. 2. Use a hobby knife to enlarge the inboard hole in one of the remaining control horns. Attach the 4 1/2" (115mm) pushrod wire to the control horn.
4. Install the micro control connector onto the elevator servo arm. Pass the elevator pushrod wire through the connector. With the radio on and elevator trim centered, center the elevator. Secure the elevator pushrod wire using the 2mm x 4mm screw and a small Phillips screwdriver. 38 5. Repeat Steps 1 through 4 for the rudder servo and linkage using the 5 3/4" (145mm) pushrod wire.
6. Attach the carbon stabilizer supports between the fuselage and stabilizer. Make notches in the stabilizer and fuselage for the rods to rest in. Secure the rods using 6-minute epoxy. Note: Make sure the rods are positioned so they don't interfere with the operation of the rudder and elevator linkages.
Final Assembly Required Parts Fuselage Wing Canopy Receiver Battery Battery hatch 4-40 x 1" socket head bolt (2) #4 washer (2) Hook and loop tape Hook and loop strap 1. Plug in the elevator and rudder servos and ESC into the receiver. Mount the receiver to the inside of the fuselage using hook and loop material. Route the antenna wire through the bottom of the fuselage to the rear, or as directed by your radio instruction manual.
2. Place the canopy into position on the fuselage. Use a felt-tipped pen to trace the outline of the canopy onto the fuselage. 3. Use medium grit sandpaper to roughen the covering 1/8" (3mm) inside the line drawn. Also roughen the outside 1/8" (3mm) of the canopy. Clean the sanded areas using a paper towel and rubbing alcohol.
4. Use Formula 560 canopy glue to glue the canopy to the fuselage. Use masking tape to hold the canopy in position until the glue fully cures. 5. With the aircraft fully assembled, install the battery into the battery compartment. Secure the battery using the hook and loop tape and a hook and loop strap. Note: Place a piece of hook and loop tape on the bottom of the battery and on the fuselage where the battery rests.
6. Install the battery hatch to the top of the fuselage. The magnet will hold the battery hatch in place. 7. Attach the optional side force generators (if you wish) to the wing tips using four 4-40 x 1/2" socket head screws. Add the plywood disks between the side force generators and the wing tip to prevent the aileron from rubbing against the side force generator. Note: The side force generators can be removed in a few seconds. Try your .
Control Throws Low rate (U/D) High Rate (U/D) Elevator: 3/4" (19mm) 2 5/16" (58mm) Ailerons: 1" (25mm) 1 7/8" (48mm) Rudder: 1 3/4" (95mm) 2 3/4" (95mm) 1. Turn on the transmitter and receiver of your Mini FuntanaX. Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary. 2. Check the movement of the elevator with the radio system.
Center of Gravity An important part of preparing the aircraft for flight is properly balancing the model. Caution: Do not inadvertently skip this step! The recommended Center of Gravity (CG) location for the Mini FuntanaX is 3 3/4" (95mm) behind the leading edge of the wing against the fuselage.
Range Test Your Radio 1. Before each flying session, be sure to range check your radio. This is accomplished by turning on your transmitter with the antenna collapsed. Turn on the receiver in your airplane. With your airplane on the ground and the engine running, you should be able to walk 30 paces (approximately 100 feet) away from your airplane and still have complete control of all functions. If not, don’t attempt to fly! Have your radio equipment checked out by the manufacturer. 46 2.
Preflight Check Your Radio Before going to the field, be sure that your batteries are fully charged per the instructions included with your radio. Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying. Before each flying session, be sure to range check your radio.
Flying Your Mini FuntanaX Once you have finish the assembly of your Mini FuntanaX and have verified the center of gravity, you are ready to go. Check all the flight controls to ensure they are moving the in the correct direction and giving you the amount of throw you want. What we have listed in the high rates is enough to 3D the Mini FuntanaX with ease. Once at your park, you will find the steerable tailwheel makes taxiing of the Mini FuntanaX very easy.
