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.

1. Locate the wing struts. Place the struts onto the top
wing, which has the cutouts for the center cabane strut.
The struts angle towards the trailing edge of the wing.
Use a square and either foam compatible CA or hot
glue to secure the struts to the wing.
9
2. Attach the bottom wing to the struts using foam
compatible CA or hot glue. Again, check that the
struts are square to the wing.
3. Slide the fuselage between the wing panels. Key the
cabane into the top wing. Use foam compatible CA or
hot glue to secure the top wing to the cabane.
10
4. Rest the bottom wing flat on the work surface. Use
a square to align the fin perpendicular to the work
surface. Mark the location of the fuselage onto the
bottom wing.
5. Use hot glue to attach the bottom wing to the fuselage.
Do not use foam compatible CA for this step. Use the
marks from Step 4 for alignment.
11
Note: The long brace (11

/
") goes from
4
the top near the cabane to the strut on the
bottom wing.
6. Install the carbon wing braces by first positioning a
hole in the bottom of the lower wing by gently sliding
a carbon fiber brace through the four plastic ring
washers at the proper angle, then remove. Next, gently
slide each carbon fiber brace through the plastic ring
washers on the top of the upper wing, at the proper
angle, and have each exit though the plastic ring
washers on the bottom of the lower wing through the
holes you have already made. Glue the braces using
foam compatible CA on the insides and outside the
plastic ring washers to secure them in place.
