IMPORTANT!!!

Two of the most important things you can do to preserve the
radio controlled aircraft hobby are to avoid flying near full­scale aircraft and avoid flying near or over groups of people.

SCALE COMPETITION

Though the Great Planes Mister Mulligan EP is an ARF and
may not have the same level of detail as an “all-out” scratch­built competition model, it is a scale model nonetheless
and is therefore eligible to compete in the Fun Scale class
in AMA competition (we receive many favorable reports of
Great Planes ARF’s in scale competition!). In Fun Scale, the
“builder of the model” rule does not apply. To receive the five
points for scale documentation, the only proof required that a
full size aircraft of this type in this paint/markings scheme did
exist is a single sheet such as a kit box cover from a plastic
model, a photo, or a profile painting, etc. If the photo is in
black and white other written documentation of color must
be provided. Contact the AMA for a rule book with full details.

If you would like photos of the full-size Mister Mulligan for
scale documentation, or if you would like to study the photos
to add more scale details, photo packs are available from:

PROTECT YOUR MODEL, YOURSELF

& OTHERS… FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

INTRODUCTION

For the latest technical updates or manual corrections to the
Mister Mulligan EP visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, then select the
Mister Mulligan EP ARF. If there is new technical information
or changes to this model a “tech notice” box will appear in
the upper left corner of the page.

1. Your Mister Mulligan EP 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 Mister Mulligan EP, 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 unflyable model. In a few cases the instructions may

2

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 specified
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 flight.

5. If you are not an experienced pilot or have not flown
this type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your first flights. 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. While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high stress flying, such
as racing, or if a motor larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.

7. WARNING: The cowl, wheel pants, and some fairings are
made of fiberglass, the fibers of which may cause eye, skin
and respiratory tract irritation. Never blow into or on a part
to remove fiberglass dust, as the dust will blow back into
your eyes. Always wear safety goggles, a particle mask and
rubber gloves when grinding, drilling and sanding fiberglass
parts. Vacuum the parts and the work area thoroughly after
working with fiberglass parts.

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.

ITEMS REQUIRED

Radio Equipment

A 4-channel minimum radio system is required to fly this

IMPORTANT BUILDING NOTES

• There are three types of screws used in this kit:
Sheet metal screws are designated by

a number and a length. For example,
#6 x 3/4" [19mm]

Machine screws are designated by a
number, threads per inch, and a length.
For example 4-40 x 3/4" [19mm]

Socket Head Cap Screws (SHCS) are
designated by a number, threads per
inch, and a length. For example 4-40 x
3/4" [19mm]

• When you see the term test fit in the instructions, it means

that you should first position the part on the assembly

without using any glue, and then slightly modify or custom
fit the part as necessary for the best fit.

• Whenever the term glue is written you should rely upon

your experience to decide what type of glue to use. When
a specific type of adhesive works best for that step, the
instructions will make a recommendation.

• Whenever just epoxy is specified you may use either

30-minute (or 45-minute) epoxy or 6-minute epoxy. When
30-minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.

BEFORE YOU BEGIN

Before you begin assembling your model, inspect it for
wrinkled covering and areas where the covering should be
tacked down to the wood like the openings for the servo
bays. Use Low heat (about 250° F [121° C]) to tack down the
edges. Raise the temperature and iron over wrinkles with
light pressure. Be careful not to contact the edges that you
tacked down while shrinking.

2. Working with the left wing, remove the aileron servo

❏ ❏

bay cover. Center the servo arm in the opening with the arm
pointing out as shown. With the servo in this position, glue
two 7mm x 10mm x 14mm hardwood blocks under the servo
mounting tabs. If you are using the recommended Futaba
S3115 servos, you may simply use epoxy to glue the blocks
in the positions marked inside the cover.

Note: Save the plastic bag that the fuselage came in. It will
be used later in the assembly.

WING ASSEMBLY

Aileron Servo Installation

3. Drill mounting holes for the servo using a 1/16"

❏ ❏

[1.6mm] drill. Install the two servo screws that came with your
servo. Remove the screws and the servo and wick a drop of
thin CA into the screw threads that you just tapped in the
hardwood blocks. After the CA cures, re-install the screws.

1. Prepare a left and a right servo using your radio system

❏

to center the servos. Remove the servo arm retaining screws
and the servo arms. Install the standard size servo arms that
came with your servos. Rotate the arm on the splined servo
shaft and choose the arm that is 90° to the side of the servo
case when the servo is centered. Clip off the unused servo
arms so that your aileron servos appear as shown. Fit any
servo grommets now (if equipped).

4. Attach a 12" [305mm] servo lead extension to the

❏ ❏

aileron servo. Secure the connection with a piece of 3/8"
[9.5mm] diameter heat shrink tubing (not supplied) or wrap
the connection with electrical tape.

6

5. Tie the guide string to the end of the servo lead and

❏ ❏

carefully route the servo lead through the wing and out of the
hole in the sheeting near the root rib of the wing.

6. Orient the servo bay cover as shown and install it

❏ ❏

using four #2 x 3/8" [9.5mm] sheetmetal screws with four
#2 flat washers. Remove the screws, washers and the cover
and harden the screw holes in the wing with thin CA. Then,
re-install the cover and screws.

8. Clip off and discard the backing plate from a small

❏ ❏

control horn. Align the horn over the mark you made and
slide it forward until the pushrod holes in the horn are directly
over the hinge line. Drill two 3/8" [9.5mm] deep holes using a
1/16" [1.6mm] drill. Be careful not to drill completely through
the aileron.

9. Install the control horn using two #2 x 3/8" [9.5mm]

❏ ❏

sheetmetal screws. Remove the screws and the horn and
wick about 4-5 drops of thin CA into the screw holes you
tapped. Allow the CA to dry and reinstall the control horn.

10. Screw a clevis onto a 6" [152mm] threaded pushrod

❏ ❏

so that at least 1/8" [3.2mm] of thread protrudes past the
barrel of the clevis. Loosely fit a silicone clevis retainer to the
pushrod.

7. Using a 90° builder’s square or a builder’s triangle,

❏ ❏

make a mark on the aileron directly behind the aileron servo
arm. Align the flat base of the square with the aileron hinge
line. Then slide the square into position and make your mark.

11. Fit the clevis to the outermost hole in the aileron

❏ ❏

control horn. Extend the pushrod forward and align it with
the hole you drilled in the servo arm. With the servo arm
centered and the aileron at neutral, make a mark at the hole
in the servo arm.

7

12. Bend the pushrod 90° at the mark that you made.

❏ ❏

Fit the pushrod to the servo arm and fasten it with a FasLink
pushrod retainer. Cut off the remaining pushrod so that at
least 1/4" [6.4mm] of pushrod remains.

16. Glue the 3mm x 20mm wing alignment dowel into the

❏

left wing as shown so that at least 10mm is protruding.

Fixed Wing Flap (Option 1)

13. Repeat steps 2 through 12 to prepare the right wing.

❏

14. Glue a 6mm x 25mm wing dowel into the leading edge

❏

of each wing so that the dowel protrudes out 1/4" [6.4mm]
as shown.

On this model, you can set up the flaps one of three ways.
You can purchase two additional servos and use flaps for
landings. If you never intend to use flaps, you may glue the
flaps in the fully retracted position. If you want the option to
add flaps later you can install the control horns and fix them
in place using the supplied flap pushrod.

1. To permanently fix the flaps in the retracted position,

❏

glue the wing flap servo bay covers in place.

15. Sand the surface of the wing alignment dowel to

❏

prepare it for glue.

2. Trim the covering from the leading edge of each flap.

❏

Remove the covering from the trailing edge of the wing in
front of each flap. Trim the covering about 1/16" [1.6mm]
inside of the edge.

8

3. Mix up a batch of 6-minute epoxy. Brush epoxy on the

❏

leading edge of each flap and the corresponding trailing
edge of each wing. Glue each flap in the retracted position.
Before the epoxy cures, wipe off the excess with a paper
towel dampened with denatured alcohol.

Fixed Wing Flap (Option 2)

With this option, you can easily add operable flaps later.

6-minute epoxy, you can heat up the glue joint later and
easily remove the fixed flap retainers to convert to operable
flaps.

3. Trim away the covering from the three small holes.

❏

Install a nylon strap across the two longitudinal holes using
two of the sheetmetal screws included with the straps. Don’t
forget to harden the screw holes with thin CA. Prepare both
servo bay covers.

1. Identify the four wooden fixed flap retainers shown

❏

here. Rotate the small oval piece until the three holes in that
piece align with the three holes in the larger piece. Glue the
small oval piece to the larger piece. Use the laser-etched
outline and the holes to center the small oval piece. Allow the
glue to dry. Note: The pair that you create will not be mirror
images because both flap servo arms must operate in the
same direction as they exit the wing.

2. Glue the pieces into the flap servo bay covers using

❏

6-minute epoxy. Do not remove the covering. By using

4. Install the covers onto the wings. Be careful to orient

❏

the covers properly as shown.

9

5. Working with the left wing first, make a mark on the

❏ ❏
