INTRODUCTION

If you’ve built any of the previous Great Planes Indoor Aerobatic

planes, the Citabria 3D Indoor EP ARF uses the same proven

methods. If this is your fi rst Great Planes Indoor Aerobatic

plane, you will be surprised at how quickly and easily you can

have it in the air. The building crutches make aligning the parts

a non-issue. So let’s get this plane built and go have some fun.

SAFETY PRE CAUTION S

Protect Your Model, Yourself & Others …
Follow These Important Safety Precautions

1. Your Citabria 3D Indoor EP ARF should not be considered

a toy, but rather a sophisticated, working model that
functions very much like a full-size airplane. Because of its
performance capabilities, the Citabria 3D, if not assembled
and operated correctly, could possibly cause injury to
yourself or spectators and damage to property.

2. You must assemble the model according to the

instructions. Do not alter or modify the model, as doing

so may result in an unsafe or unfl yable model. In a few
cases the instructions may differ slightly from the photos.
In those instances the written instructions should be
considered as correct.

3. You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in good condition,

a correctly sized engine, and other components as specifi ed
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model

and all components before every fl ight.

2

5. If you are not an experienced pilot or have not fl own this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your
local hobby shop has information about clubs in your area
whose membership includes experienced pilots.

6. Carefully read and follow all the instructions included with
your LiPo battery and battery charger. LiPo batteries are
not forgiving like NiCd or NiMH batteries. Overcharging or

charging the LiPo battery at too high a current will damage

the battery and could damage property.

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to
the performance or safety of your completed model.

Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.

DECISI ONS YOU MUST MAKE

Charger

A LiPo compatible charger is required to charge LiPo batteries.

The Great Planes ElectriFly PolyCharge4™ is designed for

LiPo packs only; however, it is able to charge four LiPo packs
simultaneously. The ElectriFly Triton2™ and AC/DC Triton2 EQ
chargers will only charge one pack at a time, but are capable
of charging NiCd, NiMH, Pb acid and LiPo batteries. Order
numbers are provided below.

Charger (GPMM3015)

OR

Great Planes ElectriFly Triton2 DC Comp Peak

❍

Charger (GPMM3153)

OR

Great Planes AC/DC Triton2 EQ Charger/Balancer

❍

(GPMM3156)

Throughout the life of a LiPo battery, the individual cells

located inside the battery may become unbalanced. These

unbalanced cells can shorten the life of the battery or cause

it to malfunction. For this reason, it is always recommended

that a cell balancer be used when charging LiPo batteries.

The Electrifl y Equinox™ is a cell balancer that may be used

with any LiPo charger and is capable of maintaining the cell

balance of the battery. Note: The AC/DC Triton2 EQ does

not require a cell balancer.

BUILD THE FUSELAGE

Assemble the Fuselage

1. Locate the two ABS landing gear supports. Glue

❏

a landing gear support to each side of the fuselage in the
location shown.

4. Insert the aft end of the horizontal fuselage into the

❏

front of the vertical fuselage. Key the horizontal and vertical
fuselages together.

2. Remove the nine fuselage alignment crutches from

❏

the surrounding foam. Note: Use a sharp hobby knife to cut

the crutch parts from the surrounding foam, trimming the tabs

fl ush with the edges of the crutches.

3. To prevent the parts from adhering to your building table,

❏

place a piece of waxed paper, or the clear plastic bag the
parts came in, on your table. Use foam safe CA to glue the

nine alignment crutch feet to the alignment crutches. Make

sure the crutches and feet are fl at against the building table
and that the crutches are perpendicular to the table.

5. On your building table, place the four bottom crutches

❏

with the feet on them underneath the fuselage in the locations
shown. Crutch #1 is positioned in line with the bottom of the
windscreen. Crutch #2 is positioned at the fi rst hole in the
side of the fuselage. Crutch #3 is positioned at the third hole

in the side of the fuselage. Crutch #4 is positioned at the fi fth
hole in the side of the fuselage, just under the leading edge
of the stabilizer.

6. Test fi t the #1, #2 and #3 top crutches over their

❏

corresponding bottom crutches. Install the ABS motor mount
onto the front of the fi rewall, but DO NOT glue it in place at

this time. Check that all the crutches are seated against the
fuselage and the horizontal and vertical fuselages are keyed
together. Then, glue the top and bottom of crutches #1, #2
and #3 together by applying small amount of foam-safe CA to

the tabs of the crutches. Be careful not to glue the crutc hes

to the fuselage.

7. Position the #4 top crutch over the corresponding #4

❏

bottom crutch.

5

8. Make sure the horizontal and vertical fuselages are keyed

❏

together and the crutches are fl at on your building table. Glue
the horizontal and vertical fuselages together by applying thin
foam-safe CA along the joint between the two. Be careful when
gluing around the crutches. DO NOT glue the crutches to the
fuselage. Allow the CA to cure for a few minutes before moving
the plane. The use of foam-safe accelerator will quicken the
curing of the CA, but use it sparingly. Excessive amounts of
accelerator can cause the CA to cure quickly, causing it to
get hot and melt the foam.

and #4 crutches are fl at on the building table. The #2 building
crutch should be fl at on the wing. Check that the horizontal
and vertical fuselages are keyed together. Use foam-safe CA
to glue the bottom of the horizontal and vertical fuselages
together and the wing and vertical fuselage together.

Install the Wing Supports

9. On the left side of the fuselage, from the aft end, slide the

❏

diagonal support with the hole in it, under the crutches. Align

the hole in the diagonal support with the hole in the horizontal
fuselage. Use foam-safe CA to glue the diagonal support at a

45 degree angle against the horizontal and vertical fuselages.

10. Insert and glue the second diagonal support on the

❏

right side of the fuselage. Make sure the aft end of the right
diagonal support is the same distance from the rudder hinge
line as the left diagonal support.

1. Locate the two ABS brace supports. There is a slot

❏

located in the center of each wing. Glue the ABS brace
supports into the slots, perpendicular to the underside of the
wing. It is possible that, during manufacturing, some glue

may have gotten into the slot. If this has happened, DO NO T
FORCE the supports into the slot. Use a sharp hobby knife

to remove any excess glue.

11. Place the wing upside down on the building table.

❏

Carefully turn the Citabria over and key the top of the fuselage

into the bottom of the wing. Note that the vertical fi n will need
to hang over the edge of the building table. Check that #1, #3

2. Locate the four long and two medium ABS brace

❏

doublers
Note: For steps 3 through 5, DO NOT glue the parts until

told to do so.
