Safety, Precautions, and Warnings As the user of this product, you are solely responsible for operating it in a manner that does not endanger yourself and others or result in damage to the product or the property of others. Carefully follow the directions and warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.) that you use. This model is controlled by a radio signal that is subject to interference from many sources outside your control.
Motor Installation 2. Lightly sand the motor tube once the adhesive used to glue the motor to the motor tube has fully cured. 3. Remove the two screws holding the cowl to the fuselage and slide the cowl away from the fuselage. Required Parts • Fuselage • Receiver • Park 250 Brushless motor • Electronic speed control (ESC) 1 • 1 /2-inch (38mm) motor tube Required Tools and Adhesives • Phillips screwdriver • RTV silicone • Double-sided tape • Foam-safe CA • Sandpaper 1.
4. Slide the motor assembly into the fuselage. 6. Position the motor so is does not rub against the cowl. Apply a few drops of foam-safe CA to the intersection of the fuselage and motor tube. 5. Slide the cowl back in position and attach it to the fuselage. Attach the propeller to the motor following the instructions provided with the motor. 7. Once the CA has cured, remove the propeller and cowl. Apply foam-safe CA to the tube at the front of the motor box.
10 8. Plug the leads from the motor to the speed control. Attach the speed control using double-sided tape as shown. 9. Use double-sided tape to secure the receiver inside the fuselage. Position the antenna wires according to your radio manual. Never shorten the receiver antenna wire, as this will greatly reduce the range of your radio system. 10. Turn on the transmitter and bring the throttle trim and stick to the low throttle position.
Rudder and Elevator Installation Required Parts • Rudder/Fin • Micro control horn (2) 2. Slide a micro control horn into the slot in the elevator from the bottom. • Elevator/Stabilizer • Micro control horn backplate (2) Required Tools and Adhesives • Square • Foam-safe CA • Sandpaper 1. Position the rudder/fin tab into the slot in the stabilizer/elevator. The yellow side of the stabilizer/ elevator faces the rudder/fin.
4. Repeat Steps 2 and 3 to install the rudder control horn. 5. Position the assemble onto the fuselage. Check the alignment as shown in the drawing. The rudder must be parallel to the cabane struts. If not, lightly sand the fuselage where the elevator rests and check the alignment again. Once the alignment is correct, use foam-safe CA to glue the assembly to the fuselage. Rudder parallel to cabanes Note: The rudder horn is opposite the elevator horn.
Radio Installation Required Parts • Assembled fuselage Sub-micro servo (2) • Micro pushrod connector (2) • 2mm x 4mm machine screw (2) • Micro pushrod connector backplate (2) 3. Mount the elevator servo in the fuselage using the screws provided with the servo. Required Tools and Adhesives • Hobby knife • Phillips screwdriver 1. Use a hobby knife to enlarge the outer hole in the servo arm. Slide the micro pushrod connector into the hole. 4.
5. Check to make sure the elevator and stabilizer are parallel. 7. Repeat Steps 1 through 6 to install the rudder servo and linkage. 6. Slide the pushrod wire through the connector. With the elevator centered, thread a 2mm x 4mm machine screw in the connector and tighten it to secure the pushrod wire.
8. Reinstall the cowl and propeller. If the motor rubs on the cowl, enlarge the holes for the screws that secure the cowl so it can be repositioned enough so the motor does not rub the cowl. 9. Use hook and loop tape to secure the battery inside the cowl. The battery can be moved forward or backward to adjust the Center of Gravity.
Wing Installation 2. Slide the outer struts through the bottom wing. Note the direction of the strut. The rear has an angle, while the front is straight. 3. Use a hobby knife to make two small holes in the mounting points of the cabane struts. Make the hole in the rear mounting pads at this time.
4. Use a felt-tipped pen to mark the holes made in the previous step. This will help in sighting the holes through the wing. 5. Attach the rear of the top wing using two 2mm x 4mm sheet metal screws. Mark the locations for the front screws through the wing on the mounting pads. The cabane struts may require some adjustments to line up with the holes in the wing. E-flite Jenny JN-4 Slow Flyer ARF Assembly Manual 6.
7. Apply foam-safe CA to the strut where it will come in contact with the bottom wing. Push the strut tight against the wing. 9. Locate the inner struts. Select a front and rear strut. The rear strut has a greater angle than the front as shown in the photo below. 10. Position the inner struts between the top and bottom wing. Use foam-safe CA to glue the struts to the wings. 8. Apply foam-safe CA to the ends of the struts where they come in contact with the top wing.
Landing Gear Installation Required Parts • Airframe • Wheel (2) 2. Press the front of the gear into the opening in the fuselage. 3. Press the rear of the gear into the slot in the wing and into the fuselage. • Landing gear • Wheel retainer (2) Required Tools and Adhesives • Foam-safe CA 1. Locate the landing gear. Position the gear with the main axle toward the front of the plane.
4. Slide a wheel onto the axle. Use a wheel retainer to secure the wheel. Wing Rigging Installation Required Parts • Airframe • Rigging thread Required Tools and Adhesives • Foam-safe CA Note: Installing the rigging will add to the appearance and strength of your airplane, but you will not be able to remove the wings without cutting the rigging. The rigging is required if you plan on any type of aggressive flying with your Jenny. 1.
2. Guide the thread through the hole in the inner strut. 3. A tube has been installed in the fuselage to pass the rigging thread through to the opposite side of the fuselage. E-flite Jenny JN-4 Slow Flyer ARF Assembly Manual 4. The rigging thread goes through the hole in the inner strut then to the outer strut. Glue the thread to the strut using foam-safe CA. 5. Apply very light tension to the rigging thread and apply foam-safe CA to the thread to attach it to the strut.
6. When installing the rigging from the bottom of the outer strut, the rigging will pass through holes in the cabane struts as shown. Control Throws 1. Turn on the transmitter and receiver of your aircraft. 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. Range Test Your Radio Caution: Do not inadvertently skip this step! The recommended Center of Gravity (CG) location is 2-inches (51mm) behind the leading edge of the top wing against the cabane struts. Model is balanced in an upright position. E-flite Jenny JN-4 Slow Flyer ARF Assembly Manual 1. Before each flying session, be sure to range check your radio.
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.
2007 Official AMA National Model Aircraft Safety Code GENERAL 1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested. 2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full-scale aircraft.
