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.

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.

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.

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

 5. Work the aileron up and down several

 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.

20

 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.

21

 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.

 6. Hinge the elevator and stabilizer, using the

same process as described in Aileron Hinging
Use 4 hinges for this process.

.

22

 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.

 1. Place the fin in position on the fuselage. Trace

the outline of the fuselage onto both sides of the
fin.

 2. Remove the covering from the bottom of the fin

using the same technique used for the stabilizer.

24

 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.

25

 5. Use a sharp hobby knife to cut a slot in the aft

end of the fuselage for the lower rudder hinge.

 6. Attach the rudder using three CA hinges. Use

the technique as described in Aileron Hinging
for this procedure.

Motor Installation

Required Parts

Fuselage Gearbox
Motor support stick
Brushless motor

Required Tools and Adhesives

6-minute epoxy Hobby knife
150–200 grit sandpaper

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. The E-flite gearbox features
adjustable slotted mounting holes so that you can
ensure your gear mesh is correct. Remember, if
your mesh is too loose or too tight, it may strip
the gears. See the instructions included with your
E-flite gearbox for more helpful tips on gear mesh
and motor installation.

 1. It may be necessary to attach motor adapters

or other accessories to your particular motor
at this time.

Proper gear mesh is extremely important for
high power set ups, such as those systems
typically used to power the Mini Funtana. Be
certain to check the mesh at multiple points
on the spur gear before finalizing the motor
mounting position in the gearbox. To extend the
life of your gearbox, we also recommend using
a small amount of grease, such as lithium grease,
on the spur gear.

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.

27

 2. Attach the motor to the gearbox using screws

provided with the motor.

 3. Locate the motor support stick. Use 6-minute

epoxy to glue the support to the two formers at
the front of the fuselage.

28

 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. Install a small screw
to secure the two items together.

75mm x 20mm x 2mm light ply
35mm x 20mm x 7mm balsa block
Brushless speed control

Required Tools and Adhesives

Hook and loop strap Thin CA

32

 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. Plug in the rudder and
elevator servos. Route the receiver antenna to
the rear of the plane.

Note: Do not cut the receiver antenna, as this will
greatly reduce the range of the radio system.

Hint: Position the receiver so the ailerons can be
plugged in easily.

 2. Install the speed control using hook and loop

material. Attach the ESC to the side of the
fuselage to provide room for the motor battery.

33

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.

34

Canopy Install

Required Parts

Fuselage Canopy

Required Tools and Adhesives

Canopy glue Wax paper
Felt-tipped pen
150–220 grit sandpaper

 1. Place a piece of wax paper between the rear of

the canopy hatch and fuselage.

 2. Position the canopy. Trace the outline of

the canopy onto the canopy hatch using a
felt-tipped pen.

35

 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.

 4. Glue the canopy to the hatch using canopy

glue. Tape the canopy into position until the
glue cures.

 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.

37

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.

 3. Press the spinner into position on the

gearbox shaft.

38

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.

 2. Check the movement of the elevator with the

radio system. Moving the elevator stick down
will make the airplane elevator move up.

 3. Use a ruler to adjust the throw of the elevator,

ailerons and rudder. Adjust the position of
the pushrod at the control horn to achieve the
following measurements when moving the sticks
to their endpoints

Low rate (U/D) High Rate (U/D)

Center of Gravity

An important part of preparing the aircraft for flight is

properly balancing the model.

Caution: Do not inadvertently skip this step!

For experienced pilots and extreme 3D performance,

move the wing to the forward location. This will
provide a neutral feel when inverted and will
allow the Mini Funtana to really cut loose. It is
best to increase the exponential values used to
maintain a smooth feel. The CG may be placed

7

as far back as 3

/16" (88mm).

The recommended Center of Gravity (CG) location for

1

the Mini Funtana is 3

/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

Note: The wing has two different mounting
positions, which provides more flexibility with
adjusting the CG. Using the rearward wing
position will allow the aircraft to balance at
the forward CG for precision aerobatics. The
forward wing position is used to achieve the
rearward CG for extreme 3D aerobatics.

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.

 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.

2004 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.

42

3) At all flying sites a straight or curved line(s) must
be established in front of which all flying takes place
with the other side for spectators. Only personnel
involved with flying the aircraft are allowed at or in
the front of the flight line. Intentional flying behind the
flight line is prohibited.

4) I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission. (Only properly licensed
Amateurs are authorized to operate equipment on
Amateur Band frequencies.)

5) Flying sites separated by three miles or more
are considered safe from site-to site interference,
even when both sites use the same frequencies. Any
circumstances under three miles separation require a
frequency management arrangement, which may be
either an allocation of specific frequencies for each site
or testing to determine that freedom from interference
exists. Allocation plans or interference test reports
shall be signed by the parties involved and provided
