Landing Gear Installation Required Parts Fuselage Tail skid 11/2" (38mm) Wheel (2) 2mm nut (4) 4-40 x 1/2" socket screw (2) 2mm x 6mm wood screw (2) Carbon main gear Wheel pant (2) 2mm x 25mm screw (2) #4 washer (black) (2) 2mm washer (4) Required Tools and Adhesives Threadlock Drill Hobby knife Phillips screwdriver (small) 1/8" (3mm) drill bit Medium CA Hex wrench: 3/32" 1. Slide the 2mm x 25mm screw through one of the wheels. Thread a 2mm nut onto the screw. Slide a 2mm washer onto the screw.
2. Fit the assembly from Step 1 into the wheel pant. Use a 2mm washer and nut to attach the wheel to the lower hole on the landing gear. Note: Use threadlock on both nuts to prevent them from loosening during flight. 3. Repeat Steps 1 and 2 for the remaining wheel and pant. 8 4. Drill 1/8" (3mm) holes in the tail for the tail skid.
5. Glue the tail skid into position using Medium CA. 6. Attach the landing gear using a 3/32" hex wrench, two 4-40 x 1/2" socket head screws and two #4 washers (black).
7. Place the fuselage on its wheels and position the wheel pants parallel to the work surface. Drill a hole through the landing gear into each wheel pant using a hobby knife. 10 8. Secure the location of the wheel pants using 2mm x 6mm wood screws and a small phillips screwdriver.
Aileron Hinging Required Parts Wing (left and right) CA hinges (8) Aileron (left and right) Required Tools and Adhesives 3/32" (2.5mm) drill bit T-pins Paper towel Drill Thin CA 1. Locate the positions for the hinges. Drill a 3/32" (2.5mm) hole in the center of each slot. This creates a tunnel for the CA, allowing the CA to penetrate into the hinge better, bonding the hinges more securely.
2. Slide four hinges into the slits in the wing. 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. 12 Note: Do not use CA accelerator during the hinging process. The CA must be allowed to soak into the hinge to provide the best bond. Using accelerator will not provide enough time for this process.
3. Slide the aileron into position. Check to make sure it can move without interference at the wing root. Remove the T-pins and apply Thin CA to each hinge. Make sure the hinge is fully saturated with CA. Use a paper towel to clean up any excess CA from the wing and aileron. Make sure to apply CA to both sides of the hinge. 4. Firmly grasp the wing and aileron and gently pull on the aileron to ensure the hinges are secure and cannot be pulled apart.
5. Work the aileron up and down several times to work in the hinges and check for proper movement. Aileron Servos and Linkages Required Parts Wing panel (right and left) Micro control connector (2) 2mm x 4mm screw (2) 4" (100mm) pushrod (2) Control horn and backplate (2) Servos: JR 241 Sub-micro servo (JRPS241) (2) Large Arm w/Screws (JRPA212) (2) Required Tools and Adhesives Hobby knife 6-minute epoxy 6" (150mm) servo extension (2) String Phillips screwdriver (small) 6.
1. Install the grommets and brass eyelets on the servo using instructions provided with the radio system. 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. Note: We suggest using the Large Arms w/ Screws (JRPA212) on all JR® servos for the Mini Funtana. Replace all existing arms before installing the servos.
3. Secure the aileron servo using the screws provided with the servo. 4. Use a hobby knife to enlarge the center hole in the control horn to fit the 4" (100mm) long aileron pushrod wire. 5. Repeat Steps 1 through 4 for the other wing panel.
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. 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.
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. Center the aileron, and secure the position of the wire using the 2mm x 4mm screw and a phillips screwdriver. Wing Installation Required Parts Fuselage Wing (right and left) Wing tube #4 washer (silver) (2) 4-40 x 1/2" socket head screw (2) Hex wrench: 3/32" 1.
2. Remove the hatch from the fuselage. Slide the wing panel with tube into position on the fuselage. 3. Slide the remaining wing panel into position. Secure the panels using 4-40 x 1/2" socket head screws with #4 washers (silver) using a 3/32" hex wrench. Note: There are two locations for the wing tube in the fuselage. Use the rear hole (rearward wing location) at this time. Details regarding the different wing positions are described under the Center of Gravity section.
Stabilizer and Elevator Required Parts Fuselage w/wing installed Elevator Required Tools and Adhesives Hobby knife Ruler Thin CA Stabilizer CA hinge (4) Felt-tipped pen T-pins 1. Position the stabilizer into the slot in the aft end of the fuselage. Measure from the fuselage to the tips to center the stabilizer. 20 2. Measure from the stab tip to the wing tip. Adjust the stab until the measurements are equal.
3. 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. 4. 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.
5. 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. 22 6. Hinge the elevator and stabilizer, using the same process as described in Aileron Hinging. Use 4 hinges for this process.
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 Felt-tipped pen Thin CA Square 1. Place the fin in position on the fuselage. Trace the outline of the fuselage onto both sides of the fin. 24 2. Remove the covering from the bottom of the fin using the same technique used for the stabilizer.
3. 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. 4. Use thin CA to glue the fin to the fuselage.
5. Use a sharp hobby knife to cut a slot in the aft end of the fuselage for the lower rudder hinge. 26 6. Attach the rudder using three CA hinges. Use the technique as described in Aileron Hinging for this procedure.
Motor Installation Required Parts Fuselage Motor support stick Brushless motor Gearbox Required Tools and Adhesives 6-minute epoxy 150–200 grit sandpaper Hobby knife 1. It may be necessary to attach motor adapters or other accessories to your particular motor at this time. Note: When installing your motor into the E-flite gearbox, it is very important that your gear mesh is set correctly and the gear’s mesh is smooth with no binding.
2. Attach the motor to the gearbox using screws provided with the motor. 28 3. Locate the motor support stick. Use 6-minute epoxy to glue the support to the two formers at the front of the fuselage.
4. Slide the gearbox into position on the motor support stick. Trial fit the cowl in position at this time to be sure the gearbox, motor and propeller fit in position without interference with the front of the cowl. Next, trial fit the propeller onto the gearbox hex nut. If the propeller and spinner have too much clearance, it may be necessary to trim or sand part of the motor support stick at this time. Use a hobby knife to drill a small hole though the plastic gearbox and into the motor support.
Rudder and Elevator Servos Required Parts Fuselage Micro control horn w/backplate (2) 53/4" (145mm) pushrod wire 2mm x 4mm screw (2) 41/2" (115mm) pushrod wire Micro control connector w/retainer (2) Servos: JR 241 Sub-micro servo (JRPS241) (2) 9" (230mm) servo extension (2) Required Tools and Adhesives Phillips screwdriver (small) 1. Install the grommets and brass eyelets in the elevator servo. Secure a 9" (230mm) servo extension to the servo.
3. Attach the micro control horn to the elevator using the control horn backplate and 6-minute epoxy. 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.
5. Repeat Steps 1 through 4 for the rudder servo and linkage using the 53/4" (145mm) pushrod wire.
1. Trim the 75mm x 20mm x 2mm light ply to fit in position between the fuselage longerons. You will need to trim the length once the Center of Gravity has been determined. Check to make sure all servo wires and ESC wires can reach the location of the receiver before mounting the light ply receiver tray. Once the everything has been checked, use thin CA to glue the ply into position. Cut a piece of the hook and loop tape to the size of the receiver. Install the receiver using the hook and loop.
Note: When mounting the EFLA311 ESC, a 35mm x 20mm x 7mm balsa block is required to space the ESC away from the fuselage side. 3. Install the battery in the fuselage using the remaining piece of hook and loop material. The battery must be mounted close to the firewall for proper Center of Gravity. Hint: You may use a piece of hook and loop strapping around the battery to help secure it in position.
Canopy Install Required Parts Fuselage Required Tools and Adhesives Canopy glue Felt-tipped pen 150–220 grit sandpaper 2. Position the canopy. Trace the outline of the canopy onto the canopy hatch using a felt-tipped pen. Canopy Wax paper 1. Place a piece of wax paper between the rear of the canopy hatch and fuselage.
3. Lightly sand the inside edge of the canopy where it contacts the hatch. Also sand the hatch inside the line drawn in the last step. 36 4. Glue the canopy to the hatch using canopy glue. Tape the canopy into position until the glue cures.
Cowling Install Required Parts Fuselage 12x6 propeller 3mm lock nut 2mm x 8mm wood screw (4) Cowling Spinner 3mm washer 1. Slide the cowl onto the fuselage. Center the motor shaft in the opening. Check to make sure the propeller and spinner will not interfere with the front of the cowl and there is adequate clearance. Secure the cowl to the fuselage using the 2mm x 8mm wood screws and a phillips screwdriver.
Note: It is very important that you check to be sure the propeller is balanced before installing onto the shaft. An unbalanced propeller may strip the gear. When installing the propeller, please do not over tighten the 3mm lock nut. The use of the lock nut will prevent the propeller from coming loose. 2. Attach the propeller using the supplied 3mm washer and 3mm lock nut. Make sure not to over-tighten the 3mm lock nut. 38 3. Press the spinner into position on the gearbox shaft.
Control Throws 1. Turn on the transmitter and receiver of your Mini Funtana. 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. Low rate (U/D) High Rate (U/D) Elevator: 3/4" (19mm) 25/16" (58mm) Ailerons: 1" (25mm) 17/8" (48mm) Rudder: 13/4" (95mm) 23/4" (95mm) 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 Funtana is 31/8" (80mm) behind the leading edge of the wing against the fuselage. Use this CG and the rearward wing position to the first flights until you have become more experienced. 40 For experienced pilots and extreme 3D performance, move the wing to the forward location.
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. 2. Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction.
