dimensional vacuum formed fuselage version of the original
E-flite™ profile Ultimate. The stiffer fuselage construction
means less flex making this model better equipped to handle
outdoor flying, yet it’s light enough to still fly indoors. The
Ultimate FX 3D is a great freestyle aerobatic foamie and has
added carbon fiber support stiffeners for reinforcement and
added wing support to make this a great outdoor 3D foamie.
We provide a 6.6:1 gearbox and a 12 x 6 propeller so you
can easily add our E-flite Park 370 Inrunner Brushless Motor,
4100Kv for high extreme performance. Like many other
E-flite models, you will not be disappointed with the added
features such as a painted lightweight fiberglass cowl, formed
wheel pants, and a pre-painted trim scheme.

Important Information about Motor
Selection
We are recommending the E-flite™ Park 370 Brushless
Motor with 4100Kv (EFLM1000) or the Park 400 Outrunner
Brushless Motor, 920Kv (EFLM1305). The Park 370 Brushless
Motor, 4100 Kv provides plenty of power for sport and 3D
pilots with the ability to hover and climb vertically using the
included 6.6:1 gearbox and 12x6 propeller. It is extremely
important to monitor gearbox wear and motor temperature
when using the 4100Kv motor. Lack of proper throttle
management using this motor may result in damage to the
motor, gearbox, ESC, and battery. Proper motor cooling is
very important so make sure the motor is cooled properly in
the cowl. A direct drive Outrunner alternative would be the
Park 400 Outrunner, 920Kv that will also provide plenty of
power without worrying about gearboxes.
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
Before Starting Assembly
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.
Lithium Polymer batteries are significantly more volatile
than alkaline or Ni-Cd/Ni-MH batteries used in RC
applications. All manufacturer’s instructions and warnings
must be followed closely. Mishandling of Li-Po batteries
can result in fire.
Before beginning the assembly of your Ultimate FX 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.

Important Information About Your Brushless ESC
Make sure your ESC brake is programmed to off. Also, be
sure to use an ESC with the proper 9V cutoff when using
3-Cell Li-Po packs. We suggest this cutoff to be of the soft
variety to prevent hard motor cutoffs during low-level 3D
flying.
1. It may be necessary to attach motor adapters or other
accessories to your particular motor at this time.
Note: Use the instructions provided with the
motor to install any accessories. Follow the
instructions provided with the gearbox for some
helpful hints for installing the motor. When
installing your motor into the E-flite™ gearbox,
it is very important that the gear mesh is set
correctly and is smooth with no binding. The
E-flite gearbox features adjustable slotted
mounting holes to ensure your gear mesh is
correct. Remember if the gear mesh is too loose
or too tight, it may strip the gears. 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 also very important to check to be sure the
propeller is balanced before installing onto the
shaft. An unbalanced propeller may strip the
gears. When installing the propeller, please
be sure not to over-tighten the 3mm locknut.
The use of the locknut will prevent the propeller
from coming loose.
Use the 10-tooth pinion we include with this
airplane on the motor.
31
Note: Skip to Page 33 for Outrunner
installation.
2. Attach the motor to the gearbox using the screws
provided with the motor.
3. Slide the gearbox onto the motor shaft. Use a hobby
knife to drill a hole through the plastic and into the
motor mount stick. Secure the gearbox using a
2mm x 8mm sheet metal screw.
Hint: You may want to plug in the speed control
before installing the gearbox.
32
Note: When using the E-Flite outrunner motor
and mount, you will need to shorten the motor
mount stick by 13/16" (20mm).
Attach the outrunner motor using the outrunner
stick mount (EFLM1915). Attach mount with
motor to the motor mount stick.
4. Secure the speed control location using hook and
loop. Run the lead from the speed control to the
receiver. It may be necessary to use a servo extension.
Exact speed control location may vary depending on
the brand used and the center of gravity. This photo
shows the location in the front of the fuse if you are
using our E-flite™ 20-amp Brushless ESC.

Hobby knife
1. Slide the cowl onto the fuselage. Center the motor
shaft in the opening.
2. Attach the propeller to the gearbox using the supplied
3mm washer and 3mm locknut. Make sure not to overtighten the 3mm locknut. Install the spinner into position
on the gearbox shaft. If using an Outrunner motor,
install the propeller adapter and propeller.
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 locknut. The
use of the locknut will prevent the propeller from
falling off in flight.
34
3. Check to make sure the propeller and spinner will
not interfere with the front of the cowl and there is
adequate clearance. Use a hobby knife to make holes
in the cowl at the same location as the tabs on the
fuselage. Secure the cowl to the fuselage using the
2mm x 10mm wood screws and a Phillips screwdriver.
4. Use canopy glue to glue the canopy to the canopy
hatch. Once the glue has cured, place the hatch into
position.

Battery
Hook and loop
1. The battery for the Ultimate FX is located inside
the front of the fuselage behind the firewall. The
battery attaches to the side of the fuselage with
hook and loop material.
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
Ultimate FX is 3
1
/
" (90mm) to 4" (100mm) behind the
2
leading edge of the upper wing against the fuselage.
The C.G. range was determined from our flight tests using a
Thunder Power 11.1V 1320mAh Li-Po battery pack.
36
Control Throws
1. Turn on the transmitter and receiver of your Ultimate
FX. 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.
Ailerons:
Low Rate 1" (25mm) or 20 degrees Up/Down

2005 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.
38
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
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
to AMA Headquarters. Documents of agreement and
reports may exist between (1) two or more AMA
Chartered Clubs, (2) AMA clubs and individual AMA
members not associated with AMA Clubs, or (3) two or
more individual AMA members.
6) For Combat, distance between combat engagement
line and spectator line will be 500 feet per cubic inch
of engine displacement. (Example: .40 engine = 200
feet.); electric motors will be based on equivalent
combustion engine size. Additional safety requirements
will be per the RC Combat section of the current
Competition Regulations.
7) At air shows or model flying demonstrations, a
single straight line must be established, one side of
which is for flying, with the other side for spectators.
8) With the exception of events flown under AMA
Competition rules, after launch, except for pilots or
helpers being used, no powered model may be flown
closer than 25 feet to any person.
9) Under no circumstances may a pilot or other person
touch a powered model in flight.
