Introduction
Thank you for purchasing the E-flite Mini Funtana 3D
ARF Park Flyer. The Mini Funtana is an extreme 3D
aerobatic electric park flyer, based on the proven
abilities of the popular Hangar 9 FuntanaS airplanes.
We developed this aerobatic performer especially
for park flyers pilots who are looking for great 3D
performance.
The designed characteristics incorporated into the
Mini Funtana, in addition to the lightweight balsa
and light-ply construction, should provide you with
the optimized precision 3D freestyle aerobatics you
desire. We also include plenty of extras like the
carbon fiber landing gear, fiberglass cowl and wheel
pants, and a gearbox that easily accepts one of our
popular Park 400 Brushless Motors (EFLM1100 or
ELFM1105- purchased separately).

Before Starting Assembly
Before beginning the assembly of your Mini Funtana
3D, remove each part from its bag for inspection.
Closely inspect the fuselage, wing panels, rudder
and stabilizer for damage. If you find any damaged
or missing parts, contact the place of purchase.
Using the Manual
This manual is divided into sections to help make
assembly easier to understand, and to provide
breaks between each major section.
Remember to take your time and follow
the directions.
Warning
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following
all instructions included with your radio.
Important Information About Motor
Selection
We are recommending either the E-flite Park 400
Brushless Motor with 4200Kv (EFLM1100) or the
version with 3700Kv (EFLM1105). The 3700Kv
motor provides plenty of power for sport and
entry level 3D pilots with the ability to hover and
climb vertically using the stock 6.6:1 gearbox and 12
x 6 propeller. This motor will draw less current and
provide longer flight duration. The 4200Kv
motor should only be used by experienced pilots
who manage throttle appropriately. This motor will
provide even better vertical performance at the
expense of flight duration due to the increased
current draw. It is extremely important to monitor
gearbox wear and motor temperature when using
the 4200Kv motor. Lack of proper throttle
management using this motor may result in damage
to the motor, gearbox, esc, and battery.

Landing Gear Installation
Required Parts
Fuselage Carbon main gear
Tail skid Wheel pant (2)
11/2" (38mm) Wheel (2) 2mm x 25mm screw (2)
2mm nut (4) #4 washer (black) (2)
4-40 x 1/2" socket screw (2) 2mm washer (4)
2mm x 6mm wood screw (2)
Required Tools and Adhesives
Threadlock 1/8" (3mm) drill bit
Drill Medium CA
Hobby knife Hex wrench: 3/32"
Phillips screwdriver (small)
 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. This will all
fit inside the wheel pant.

8
 4. Drill 1/8" (3mm) holes in the tail for the
tail skid.
 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.

 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).
9

 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.
 8. Secure the location of the wheel pants using
2mm x 6mm wood screws and a small phillips
screwdriver.
10

Aileron Hinging
Required Parts
Wing (left and right) Aileron (left and right)
CA hinges (8)
Required Tools and Adhesives
3/32" (2.5mm) drill bit Drill
T-pins Thin CA
Paper towel
 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.
11

 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.
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.
12

 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. Use caution
when gripping the wing and aileron to avoid
crushing the structure.
13

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)
 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.
14

 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.
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.
15
 2. Place the servo in the wing. Guide the servo
lead out through the opening at the wing root.

 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.
16

 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.
17
 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. Slide the wing tube into a wing panel.
18

 2. Remove the hatch from the fuselage. Slide
the wing panel with tube into position on the
fuselage.
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.
19
 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.

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. Position the stabilizer into the slot in the aft end
of the fuselage. Measure from the fuselage to
the tips to center the stabilizer.
 2. Measure from the stab tip to the wing tip. Adjust
the stab until the measurements are equal.
