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. This
interference can cause momentary loss of control so it is
necessary to always keep a safe distance in all directions
around your model, as this margin will help to avoid collisions
or injury.
• Always operate your model in an open area away from cars,
traffic, or people.
• Avoid operating your model in the street where injury or
damage can occur.
• Never operate the model out into the street or populated
areas for any reason.
• Never operate your model with low transmitter batteries.
• Carefully follow the directions and warnings for this and any
optional support equipment (chargers, rechargeable battery
packs, etc.) that you use.
• Keep all chemicals, small parts and anything electrical out of
the reach of children.
• Moisture causes damage to electronics. Avoid water exposure
to all equipment not specifically designed and protected for
this purpose.
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. Plug the battery into
the speed control and check the operation of the motor.
It should rotate counterclockwise when viewed from the
front of the aircraft. Use the instructions provided with
your ESC to make corrections to the direction of rotation
of the motor if necessary.
• Micro control horn (2) • 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. Use a square and foamsafe CA to glue the two items together, making sure the
rudder/fin is square to the stabilizer/elevator.
2. Slide a micro control horn into the slot in the elevator
from the bottom.
3. Slide the micro control horn backplate onto the control
horn from the opposite side of the elevator as the horn.
Apply a few drops of foam-safe CA onto the backplate to
secure it to the 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.
Note: The rudder horn is opposite the elevator horn.
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.
Note: We have found the model to balance out when
using a Thunder Power 480 2-cell battery with the
equipment listed in this manual. Using a 730 2-cell
battery will move the CG forward just a small amount
and will not affect the flight characteristics.
1. Position the bottom wing on the fuselage. Line the
holes in the wing up with the holes in the cross supports
in the fuselage. Use four 2mm x 4mm sheet metal screws
to attach the bottom wing to the fuselage. Do not overtighten the screws and damage the wing.
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.
6. Repeat the procedure from Steps 3 and 4 to make the
holes on the mounting pads at the front of the cabane
struts. Attach the wing using a total of four 2mm x 4mm
sheet metal screws.
Note: The alignment of the wings is very important for
smooth, predictable flight. Take your time during the next
few steps to ensure you do not build a warp into the
wing platform at any time.
4. Slide a wheel onto the axle. Use a wheel retainer to
secure the wheel.
Hint: Use medium foam-safe CA on the retainer if it
is not snug on the axle. Use care not to glue the wheel
to the axle.
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. Pass the rigging thread through the hole in the outer
6. When installing the rigging from the bottom of the
outer strut, the rigging will pass through holes in the
cabane struts as shown.
7. Complete the rigging installation because it looks great
and adds realism to your model.
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. Moving the elevator stick down will make the
airplane elevator move up.
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 is
2-inches (51mm) behind the leading edge of the top wing
against the cabane struts. Model is balanced in an upright
position.
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.
2. Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
3. Be sure that your transmitter batteries are fully
charged, per the instructions included with 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.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and with
the recommended throws). Test run the motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make
sure they are secure and in good condition. Replace any items
that would be considered questionable. Failure of any of these
components in flight would mean the loss of your aircraft.
You will find the Jenny JN-4 Slow Flyer to be a solid, honestflying model.
Ensure your CG is set according to the manual and power up
the aircraft. Move your throttle trim up slowly until the motor
just begins to spin. This will be your flight idle that will help to
establish a longer glide path and tends to make landings easier.
Before taxiing out to the runway, double-check all controls are
working in the correct direction and functioning properly. You
will find the rudder very effective; on the ground, tracking is
very predictable. Apply power smoothly and begin the takeoff
roll. Correct with rudder as necessary and apply up elevator
slowly until the model lifts off.
Note: Please do not attempt to perform any aerobatic
maneuvers with your Jenny unless you have rigged the
model with the string as outlined in this manual on page
20. The string rigging is required for loops, wing overs
and other mild aerobatic maneuvers to ensure airframe
strength and longevity.
You will find flying the Jenny to be very relaxing and easy. The
model is not designed for high banked turns or high speed
flight. Most flight is accomplished below half throttle and will
yield flights in excess of 15 minutes with a 480 2-cell battery
with a Park 250 when outfitted with the GWS 6x5 slow flyer
prop. Landing the Jenny JN-4 Slow Flyer is as easy as setting up
on final approach, lowering the throttle to idle and gliding in to
a soft touch-down.
We hope you enjoy the experience of flying the Jenny JN-4
Slow Flyer.
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.
Where necessary, an observer shall be utilized to supervise flying
to avoid having models fly in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the flying
site I use, and I will not willfully or deliberately fly my models in a
careless, reckless and/or dangerous manner.
4) The maximum takeoff weight of a model is 55 pounds, except
models flown under Experimental Aircraft rules.
5) I will not fly my model unless it is identified with my name and
address or AMA number on or in the model. (This does not apply
to models while being flown indoors.)
6) I will not operate models with metal-bladed propellers or with
gaseous boosts, in which gases other than air enter their internal
combustion engine(s); nor will I operate models with extremely
hazardous fuels such as those containing tetranitromethane or
hydrazine.
RADIO CONTROL
1) I will have completed a successful radio equipment ground range
check before the first flight of a new or repaired model.
2) I will not fly my model aircraft in the presence of spectators until I
become a qualified flier, unless assisted by an experienced helper.
3) At all flying sites a straight or curved line(s) must be established
