IMPORTANT!!! Two of the most important things y ou can do

to preserve the radio controlled aircraft hobby are to avoid

fl ying near full-scale aircraft and avoid fl ying near or over

groups of people.

PROTECT YOUR MODEL, Y OURSELF

& OTHERS....FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

1. Your Pluma 3D 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 Pluma 3D ARF, if not assembled and

operated correctly, could possibly cause injury to yourself or

spectators and damage to property.

2. Y ou must assemble the model accor ding to the instructions.

Do not alter or modify the model, as doing so may result in an

unsafe or unfl yable model. In a fe w 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 fi rst-class

condition, and a correctly sized motor and components

throughout the building process.

5. You must correctly install all R/C and other components so

that the model operates correctly on the ground and in the air .

2

6. You must check the operation of the model before every
fl ight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
the pushrods, heat shrink tubing and Z-bends or other
connectors often and replace them if they show any signs
of wear or fatigue.

• NEVER discharge below 2.5V per cell.

• NEVER place on combustible materials or leave
unattended during charge or discharge.

• ALWAYS KEEP OUT OF REACH OF CHILDREN.

7. 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.

8. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, 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.

We, as the kit manuf acturer , pro vide 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.

DECISIONS YOU MUST MAKE

This is a partial list of items required to fi nish the Pluma
3D ARF that may require planning or decision making
before starting to build. Order numbers are provided in
parentheses.

means that you should fi rst position the part on the assembly
without using any glue, then slightly modify or custom fi t
the part as necessary for the best fi t.

• Whenever the term glue is written you should rely upon
your experience to decide what type of glue to use. When
a specifi c type of adhesive works best for that step, the
instructions will make a recommendation.

• Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following steps
to get another view of the same parts.

• The stabilizer and wing incidences and motor thrust
angles have been factory-built into this model. However,
some technically-minded modelers may wish to check these
measurements anyway. To view this information visit the web

GETTING STARTED

Take the time to look over your Pluma 3D ARF. Assembly is
pretty simple and straight-forward, as you’ve already seen
by looking over the table of contents section in this manual.
Look for damage to the foam or brok en parts. The Pluma 3D
ARF uses a light-weight type of fl at foam that has a “skin”
applied to its outer surfaces. This creates a strong and rigid
airframe when completed, but special care is needed while
handling individual parts during build-up. Bending f oam parts
can cause the skin to tear and severely weak en the f oam, so
be careful not to force things into place.

❏ 2. Apply a bead of thin foam-safe CA to both sides of

the140mm carbon fi ber elevator joiner.

WING INSTALLATION

❏ 1. Lay the wing panels and horizontal tail on a fl at work

surface. Gently run your fi nger over the taped hinges to form
a secure bond between the tape and the foam.

Install the Wings

If you ever need to remove a control surface DO NOT
attempt to pull the hinge tape off – this damages the
skinned layer of the foam – use a hobby knife to cut the
hinge tape along the hinge line. Replacement hinge tape
is available from your local hobby shop. Order Dubro
Electric Flyer Hinge Tape (DUBQ0916).

❏ 1. Glue the bottom wing to the bottom of the fuselage.

Apply a bead of medium or thick foam-safe CA to the wing
saddle and the two fuselage former tabs and mount the wing.
Note: The bottom wing can be identifi ed by the servo hole
and the protruding LE stop.

66

6

Link the Ailerons

❏ 1. Locate f our 1 x 145mm carbon pushrods, eight 1 x 30mm

Z-bends, and eight 25mm pieces of heat shrink tubing.
Assemble four aileron link rods as shown in the sketch
above so that they measure 2-1/8" [156mm] from Z-bend
center to Z-bend center. See the Expert Tip below on how
to assemble pushrods.

How to Assemble Pushrods

❏ 2. Glue the interplane struts to the bottom wings using

thin foam-safe CA. Use a 90° builder’s square or the
template provided in the back of this manual to properly align
the interplane struts vertically. Note: The front edge of the
interplane struts has less curvature than the aft edge.

❏ 3. Apply thin foam-safe CA to the tabs on the interplane

struts and the center cabane strut. Install the top wing.

To join a wire Z-bend to a 1mm carbon pushrod, fi rst slide
a piece of heat shrink tubing onto the carbon rod. Next,
place the wire Z-bend alongside of the carbon rod. Slide
the heat shrink tubing over the joint and heat it. If you
are working near foam, use a hot soldering iron to shrink
the heat shrink tubing. Run the tip along the sides of the
tubing, applying heat all around the heat shrink tubing.
Check to see that the length of the pushrod is still correct.
If you’re careful, you can reposition the Z-bend after the
heat shrink tubing is completely shrunk, but it’s good
to check it before you’ve completely shrunk the tubing.
When you’re satisfi ed, apply one drop of thin CA to the
end of the heat shrink tubing that is farthest away from
the Z-bend. Be careful not to allo w the CA to wick into the
Z-bend if the Z-bend is attached to a control horn.

7

❏ 2. Locate eight aileron link horns. Fit them to the four

aileron links that you made.

horns until the top and bottom ailerons are completely parallel
with zero control throw . When you’ re satisfi ed with the aileron
position, use thin foam-safe CA to glue the aileron link horns
securely to each aileron. Run a bead along both sides of
each link horn and let the model sit until the CA cures.

❏ ❏ 5. Flip the model over and apply thin foam-safe CA to

the bottom side of each link horn. Let the CA cure.

❏ 6. Repeat steps 4 and 5 for the opposite wing.

HORIZONTAL & VERTICAL TAIL

INSTALLATION

Install the Horizontal Stabilizer

❏ 3. Locate the foam parts shown above and build two

control surface alignment tools. Note: Setting the rectangular
pad at 90 degrees is not critical.

❏ ❏ 4. Set y our model do wn on a fl at work surface with the

TE of the aileron hanging over the edge. Working with one
wing at a time, fi t the alignment tools to the top aileron. Test fi t
two aileron link rods by inserting the link horns into the slots
in the upper and lower ailerons. Adjust the position of the link

❏ 1. Test fi t the horizontal stab to the fuselage, installing it

from the rear. You’ll need to spread the fuselage seam apar t
a bit to get the stab in, so use care.

❏ 2. Align the stab v ertically and horizontally as shown in the

sketches above. If the stab doesn’t sit parallel with the plane

8

8

of the wings, lightly sand the slot using 150-grit sandpaper
until the stab is aligned.

❏ 3. When you’re satisfi ed with the fi t of the horizontal stab,

run a generous bead of thin foam-safe CA down the left and
right stab to the fuselage joints. Turn the model over and glue
the bottom of each joint as well.

Hinge the Rudder

❏ 1. Locate the 7-1/2" [190mm] strip of hinge tape. Cut the

tape so that you have one 4" [100mm] piece, one 2-3/4"
[70mm] piece, and one 3/4" [20mm] piece.

❏ 4. Make sure that the upper and low er fuselage is aligned.

Apply a few drops of foam-safe CA to the aft fuselage seam
and glue the seam together.

❏ 5. Defl ect the elev ator up and down, chec king f or free tra v el.

❏ 2. Position the rudder so that the LE of the rudder gently

touches the vertical fi n and that the top of the rudder is even
with the top of the fi n. Remove the backing paper and apply
the 100mm strip of tape to the top of the rudder on the right

side. Apply the 20mm piece to the bottom of the rudder.
Note: Pushing the r udder too hard against the fi n can fold

the beveled edge over and cause limited rudder throw.

❏ 3. Apply the 70mm piece to the center section of the

rudder, making sure that you press the tape tightly into the
crease. A straightedge is helpful here.

❏ 4. Defl ect the rudder left and right and check for free tra v el.

9

INST ALL THE SERV OS

❏ 1. Remov e the servo arm screws and the servo arms from

all three of your servos. Use your radio to center the servos.
Retain the servo arm screws.

❏ 2. Place one drop of foam-safe CA on the bottom of the

servo mounting tabs. Install the rudder servo on the right
side of the fuselage with the output shaft facing aft. Guide
the servo leads forward through the fuselage and apply a
bead of CA along the side of the servo case where it meets
the fuselage.

❏ 4. Locate the longest servo arms that came with your

servos. Since we used Futaba 3114 micro servos , w e chose
the optional fi ve-hole “X” arms that Futaba supplied with each
servo. With the elevator and rudder servos centered, test fi t
the servo arm to fi nd the long arm that aligns per pendicular
with the servo case. Clip off the other unused arms and
temporarily fi t each arm to each servo with the arm facing
down. Do not install the servo arm screw yet.

❏ 3. Install the elevator servo on the left side of the

fuselage with the output shaft facing aft. Guide the servo
leads forward through the fuselage. Note: The aileron servo
will be installed later.

PUSHROD & CONTROL HORN

INSTALLATION

Install the Control Horns

❏ 1. Locate two control horns. Turn your model over and

install one control horn to the bottom of the left elevator.
Apply a bead of thin foam-safe CA around the base of the
control horn.

10

❏ 2. Install the other control horn to the right side of the

rudder as shown. Apply a bead of thin foam-safe CA around
the base of the control horn.

Install the Pushrods

❏ ❏ 3. Install one control alignment tool onto the vertical

stabilizer to hold the rudder straight.

❏ ❏ 4. Fit the servo arm onto the rudder servo and extend

the pushrod all the way back to the rudder control horn. Fit a
Z-bend to the rudder control horn. Attach the Z-bend to the
rudder pushrod using a 25mm piece of heat shrink tubing.
Shrink the tubing with a hot soldering iron. Note: DO NOT

attempt to use a torch, cigarette lighter or heat gun near
the foam! It is nearly impossible to use these without melting

the foam.

❏ ❏ 1. Using a 1 x 560mm carbon pushrod, one metal

Z-bend, and one piece of 25mm heat shrink tubing,

build one end of the rudder pushrod. Slide three pushrod
supports onto the pushrod. Do not assemble the other end
of the pushrod yet.

❏ ❏ 2. Remove the servo arm that you temporarily fi tted

to your rudder servo. Use a #57 [1mm] drill bit to enlarge
the outermost servo arm hole. Fit the rudder pushrod to
the outermost hole. Note: If you don’t have a #57 drill bit,
carefully use your hobby knife to enlarge the hole.

❏ ❏ 5. With the pushrod straight, cut 2mm wide slots in the

fuselage for the pushrod supports using a hobby knife. Cut
the fi rst slot so that it is 5-1/2" [140mm] from the Z-bend.
Space the next slot 5-1/2" [140mm] from that and so on.
Ensure that the pushrod is completely straight and use foam­safe CA to glue the supports into the fuselage.

❏ 6. Repeat steps 1 through 5 for the elevator. Use the

1 x 490mm carbon rod and space the pushrod supports
4-7/8" [123mm] apart.

11

❏ 7. Install the servo arm screws.

MOTOR & ESC INSTALLATION

For this build-up we chose to install the Great Planes
28-26-1000 RimFire. We recommend this motor if you plan
on doing most of your fl ying outdoors.

❏ 3. If you are installing the more powerful RimFire motor , apply

a bead of thick foam-saf e CA to the fuselage-to-fi rewall joint.

❏ 4. Install the motor using three 2.5 x 8mm self-tapping

screws. Remove the screws and the motor and harden the
screw holes with one drop of thin regular CA. Be careful not
to drip any regular CA onto the foam.

❏ 1. Remove the three screws holding the Y-mount to the

back of the motor and the two screws for the prop saver.
Apply threadlocking compound to the screw threads and
reinstall the screws.

❏ 2. Test fi t your motor by holding it in place up against the

fi rewall. Make sure that the Y-mount screws fi t inside of the
clearance holes in the fi rewall. If it is necessary , carefully enlarge
the holes using a Dremel® tool or a sharp hobby knife.

❏ 5. Route the motor wires through the fi rewall and connect

them to the ESC. Use your r adio to test the direction of motor
rotation. If the motor rotates in the wrong direction, swap the
position of any two of the three motor leads and re-check the
direction of rotation. It’s easier to do this now than to fi nd out
you have to swap the leads later after ev erything is mounted
and tucked away.

12

❏ 6. Cut a 1" [25mm] strip from the supplied adhesive-

backed hook and loop material. Peel the backing paper off
and stick the loop side (fuzzy side) onto the back of your
ESC. Peel the backing paper off of the hook side and place
a few thin beads of thin foam-safe CA on the sticky backing.
Mount it in the plane in the location shown.

FINAL ASSEMBLY

Install the Wing Braces

For this section it is important that you set your model on a
fl at surface facing up. Hang the tail over the end of the table
or work with the model on an elevated box or sheet of thick
wood. Do not disturb the model until you have fi nished the
rigging process – doing so may result in a warped wing and
will affect the fl ying characteristics.

❏ 2. Install the 1 x 296mm carbon rods in the wings as

shown. Square the fuselage with the wing and glue the wing
braces in place.

❏ 1. With your plane on a le vel surface, install a 1 x 310mm

carbon rod through the hole in the center of the top wing. Run
it down to the hole at the base of the interplane strut on the
bottom wing. Install the other 1 x 310mm rod on the opposite
wing. Use a 90° square or the template in the back of this
manual to make sure that the fuselage is perpendicular to
the lower wing and that the wing struts are perpendicular
to the lower wing. When you’re satisfi ed that everything is
square, apply two drops of thin foam-safe CA to the ends of
each wing brace.

❏ 3. Locate the four 1 x 135mm outer wing braces. Two will

be used for the left wing and two for the right wing. With the
braces fi tted and the lower wing still fl at on the table, hold a
straightedged ruler against the top wing. Align the wings and
glue the braces in place.

13

Install the Aileron Servo

❏ 1. Turn the model over. Locate the two remaining control

horns. Glue them into the slots provided in the bottom of
each lower aileron.

❏ 4. Locate the two 1 x 145mm front wing supports. Route

each through its respective hole in the LE of the upper wing
and into the holes in the forward fuselage. Before you glue
them in place, check to see that the upper wing is still aligned
with the horizontal stab. When y ou’re satisfi ed, glue the front
supports in place.

❏ 5. With the wings square, place a drop of thick foam-safe

CA at the junction of the main wing braces. CA accelerator
is helpful here.

❏ 6. After the CA cures, pick up the plane and check all the

wing brace glue joints. Go back and add CA to each side of
every joint.

❏ 2. Center your aileron servo using your radio.

❏ 3. Locate the plastic servo arm provided in the kit.

Remove the servo arm from your servo. Mount the servo
arm to your standard servo arm with the arms swept forward.
Use the supplied 1.5 x 4mm self-tapping screws to install the
extended arm to the standard servo arm. Install the screws
from the bottom so that the heads of the screws face the
body of the servo. Note: The output shaft of the servo will
face toward the front of the model.

❏ 4. Install your aileron servo with the output shaft facing

forward. Remember to install the servo arm screw.

14

❏ 5. Locate the two 1 x 112mm carbon aileron pushrods,

four pieces of heat shrink tubing, and the remaining four
Z-bends. Assemble one end of the pushrods as shown.

❏ 6. Install one control surface alignment tool on each aileron.

Install the Radio, Landing Gear & Propeller

❏ 1. Plug your elev ator, aileron, and rudder servos into their

proper channels. Plug the ESC signal lead into the receiver.

❏ 7. Fit the pushrods to the servo arm. Fit the remaining

Z-bends to the aileron control horns and slide a piece of
heat shrink tubing onto the carbon rods. Shrink the tubing
with a hot soldering iron, making sure that your ailerons stay
centered in the process.

❏ 8. Install the aileron servo arm screw.

❏ 2. Cut a 1" [25mm] long piece of hook and loop material.

Stick the hook side (fuzzy side) to the back side of your receiv er.
Mount the receiver just ahead of the LE of the lower wing.

❏ 3. Locate the landing gear doubler plate. Roughen one

surface of the doubler plate using 150-grit sandpaper.

15

❏ 4. Apply se veral generous beads of medium or thic k foam-

safe CA to the back side of the landing gear doub ler (the side
you just sanded). Center the doubler over the holes in the
bottom of the lower wing and glue it in place.

❏ 5. Locate the two pre-assembled landing gear legs and

the two foam wheel pants. You should have a right and a left
side of each of these.

❏ 7. Slide each landing gear leg though the holes provided

in the wing. They will go through the wing holes fi rst, then the
fuselage side, and then cross over to the opposite fuselage
side. Rotate the landing gear rod until the wheels point
straight ahead. Glue the landing gear in place.

❏ 8. Mount the recommended propeller using a prop saver

O-ring. Please see the “Motor, Propeller, Battery, & ESC
Recommendations” section on page 3 of this manual to

match the correct prop to your motor.

❏ 6. Use medium or thick foam-safe CA to attach the wheel

pants to the landing gear legs.

❏ 9. With the hook and loop material that you ha v e left over,

separate the hook side from the loop side and stick the hook
side (bristly side) inside the fuselage. Apply the remaining
loop material to your battery packs.

16

❏ 10. Speed brakes have been provided for you if you fl y

indoors. These are optional and should not be installed until
the model has been test-fl own and properly trimmed out. Install
them between the aileron link rods so that they are centered
vertically. Use thick foam-safe CA or tape to attach these to
the link rods. These should only be used indoors and will help
keep speed constant during up and downline maneuvers.

BALANCE THE MODEL (C.G.)

Set the C.G.

In order to properly set the C.G. (center of gravity) you will need
to confi gure the airplane with all of the equipment it will have
on board when you’ re fl ying. To do this you’ll need to install the
battery pack in place and have the propeller attached.

To ensure a successful fi rst fl ight, fl y your model set up only
according to the C.G. and control surface throws specifi ed in
this manual. The throws and C.G. are not arbitrary, but have
been determined through extensive testing and accurate
record-keeping. This provides you with the best chance for
success and enjoyab le fi rst fl ights that should be surprise-free.
Additionally, the throws and C.G. shown are true, real data
which will allow the model to perform in the manner in which it
was intended when fl own by a pilot of the skill level for which
it was intended. DO NOT OVERLOOK THESE IMPORTANT
PROCEDURES. A model that is not proper ly setup may be
unstable and possibly unfl yable.

❏ 2. Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately

mark the C.G. on the bottom of the upper wing on both sides
of the center cabane strut. If you are fl ying indoors primarily,
make two marks that are 2-5/8" [67mm] from the LE of the
upper wing. If you are fl ying outdoors, make two C.G. marks
that are 2-1/2" [63mm] from the LE of the upper wing. The
total C.G. range is from 1-3/4" [44mm] forward to 3-5/16"
[85mm] aft. Do not fl y your model outside of this range.

❏ 3. Place y our fi ngers on the C .G. marks that you made . Hold

the plane up with your fi ngertips and see where it balances.

❏ 4. If the tail drops, the model is “tail heavy” and the battery

pack must be shifted forw ard or weight m ust be added to the
nose to balance. If the nose drops, the model is “nose heavy”
and the battery pack must be shifted aft or weight must be
added to the tail to balance. If additional weight is required,
use Great Planes (GPMQ4485) “stick-on” lead.

❏ 5. IMPORTANT: If you found it necessary to add any weight,

recheck the C.G. after the weight has been installed.

Balance the Model Laterally

❏ 1. Place the battery pack in the plane. Do not connect the

battery to the ESC.

❏ 1. With the wings le vel, lift the model by the motor propeller

shaft and the bottom of the fuselage under the TE of the fi n.
Do this several times.

❏ 2. If one wing always drops when you lift the model, it means

that side is heavy . Balance the airplane by adding weight to the
other wing tip. An airplane that has been laterall y balanced

will track better in loops and other maneuvers.

17

SET THE CONTROL THRO WS &

DIRECTION OF TRAVEL

Check the Control Directions

❏ 1. Turn on the transmitter and receiver and center the

trims. If necessary, remove the servo arms from the servos
and reposition them so they are centered. Reinstall the
screws that hold on the servo arms.

❏ 2. With the transmitter and receiver still on, check all the

control surfaces to see if they are centered. If necessary , adjust
the clevises on the pushrods to center the control surfaces .

These are the recommended control surface throws:

HIGH RATE

ELEVATOR: 1-3/8" [35mm], 26° up

1-3/8" [35mm], 26° down
RUDDER: 2-3/4" [70mm], 36° left

2-3/4" [70mm], 36° right
AILERONS: 2-3/8" [60mm], 43° up

2-3/8" [60mm], 43° down

LOW RATE

ELEVATOR: 1" [25mm], 17° up
1" [25mm], 17° down

RUDDER: 1-9/16" [40mm], 19° left
1-9/16" [40mm], 19° right

AILERONS: 1-9/16" [40mm], 27° up
1-9/16" [40mm], 27° down

3D RATE

❏ 3. Make certain that the control surfaces and the motor

respond in the correct direction as shown in the diagram.
If any of the controls respond in the wrong direction, use
the servo reversing in the transmitter to reverse the servos
connected to those controls. Be certain the control surfaces
have remained centered. Adjust if necessary.

Set the Control Throws

ELEVATOR: 2-1/8" [55mm], 46° up
2-1/8" [55mm], 46° down

RUDDER: 3-7/8" [100mm], 56° left
3-7/8" [100mm], 56° right

AILERONS: 2-7/8" [75mm], 58° up
2-7/8" [75mm], 58° down

PREFLIGHT

Identify Y our Model

No matter if you fl y at an AMA sanctioned R/C club site or if
you fl y somewhere on your own, you should alwa ys hav e y our
name, address, telephone number and AMA number on or
inside your model. It is required at all AMA R/C club fl ying sites
and AMA sanctioned fl ying events. Fill out the identifi cation
tag on page 21 and place it on or inside your model.

Use a ruler or the templates provided in the back of this
manual to accurately measure and set the control throw of
each control surface as indicated in the chart that follows. If
your radio does not have dual rates, we recommend setting
the throws at the low rate setting. Note: The throws are
measured at the widest part (inboard or lowest part) of the
elevators, ailerons, and rudder.

18

Charge the Batteries

MOTOR SAFETY PRECAUTIONS

Follow the battery charging instructions that came with your
radio control system to charge the batteries. Y ou should alwa ys
charge your radio batteries the night before you go fl ying, and
at other times as recommended by the radio manuf acturer.

CAUTION: Unless the instructions that came with your
radio system state differently, the initial charge on new
transmitter and receiver batteries should be done for 15
hours using the slow-charger that came with the radio
system. This will “condition” the batteries so that the next
charge may be done using the fast-charger of y our choice .
If the initial charge is done with a fast-charger the batteries
may not reach their full capacity and you ma y be fl ying with
batteries that are only partially charged.

Balance Propellers

Failure to follow these safety precautions may result
in severe injury to yourself and others.

Get help from an experienced pilot when learning to operate
electric motors.

Use safety glasses when running electric motors.
Do not operate the motor in an area of loose gravel or sand;

the propeller may throw such material in your face or eyes.
Keep your f ace and body as w ell as all spectators a wa y from

the plane of rotation of the propeller as you run the motor.
Keep these items away from the prop: loose clothing, shirt

sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.

The motor gets hot! Do not touch it during or right after
operation.

Do not throw anything into the propeller of a running motor.

Carefully balance your propeller and spare propellers before
you fl y. An unbalanced prop can be the single most signifi cant
cause of vibration that can damage your model. Not only can
screws and bolts loosen, possibly with disastrous effect, but
vibration may also damage your radio receiver and battery.

We use a Top Flite Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Prop Balancer (GPMQ5000) in our fl ight box.

Ground Check & Range Check

Always ground check the operational range of your radio
before the fi rst fl ight of the day following the manufacturer’s
instructions that came with your radio. This should be
done once with the motor off and once with motor running
at various speeds. If the control surfaces do not respond
correctly, do not fl y! Find and correct the prob lem fi rst. Look
for loose servo connections or broken wires, corroded wires
on old servo connectors, poor solder joints in your battery
pack or a defective cell, or a damaged receiver crystal from
a previous crash.

AMA SAFETY CODE (excerpts)

Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model A viation magazine, the AMA web site or
the Code that came with your AMA license.

❏ 8. Check the servo arms for secure attachment and make

sure that the arm screws are in place and are tight.

❏ 9. Reinforce holes for wood screws with thin CA where

appropriate

❏ 10. Check that all servo connectors are fully plugged into

their respective channels on the receiver.

❏ 11. Make sure any servo extension cords you may have

used do not interfere with other systems (servo arms,
pushrods, etc.).

❏ 12. Check the receiver for secure attachment. This must

not be “stuffed into place.”

❏ 13. Extend your receiver antenna.
❏ 14. Check the C.G. according to the measurements

provided in the manual.

❏ 15. Place your name, address, AMA number and telephone

number on or inside your model.

❏ 19. If you wish to photograph your model, do so before

your fi rst fl ight.

FLYING

9) Under no circumstances may a pilot or other person

touch a powered model in fl ight; nor should any part of the

model other than the landing gear, intentionally touch
the ground, except while landing.

CHECK LIST

During the last few moments of preparation your mind may
be elsewhere anticipating the excitement of the fi rst fl ight.
Because of this, you may be more likely to overlook certain
checks and procedures that should be performed before the
model is fl own. To help avoid this, a check list is provided to
make sure these important areas are not overlooked. Man y
are covered in the instruction manual, so where appropriate,
refer to the manual for complete instructions. Be sure to
check the items off as they are completed.

❏ 1. Check the motor for secure attachment.
❏ 2. Balance your propeller (and spare propellers).
❏ 3. Inspect your propeller for proper attachment. Replace

any prop saver that sho ws evidence of damage or one
that has cracks in it.

❏ 4. Check the wheels for free rotation, the axles and

landing gear for security, and add a drop of light
machine oil to the axles.

❏ 5. Make sure all hinges are securely stuck to the

fl ight controls .

❏ 6. Check the control horns for secure attachment to the

control surfaces.

❏ 7. Pull / push on each of the pushrods and check to see

that the connections do not slip.

The Pluma 3D ARF is an airplane suitable for both indoor
and outdoor fl ying. If you plan on fl ying outdoors, make sure
that you choose days with very light to calm winds (gusting
to less than 5 mph). If this is your fi rst experience with an
indoor-style foamie, seek help from experienced modelers.
Join a local fl ying club or ask your local hobby dealer where
the nearest approved fl ying sites are in your area.

CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while fl ying, you notice an alarming or unusual sound such
as a low-pitched “buzz,” this may indicate control surface
fl utter. Flutter occurs when a control surface (such as an
aileron or elevator) or a fl ying surface (such as a wing or
stab) rapidly vibrates up and down (thus causing the noise).
In extreme cases, if not detected immediately, fl utter can
actually cause the control surface to detach or the fl ying
surface to fail, thus causing loss of control followed by
an impending crash. The best thing to do when fl utter is
detected is to slow the model immediately by reducing
power , then land as soon as saf ely possible . Identify which
surface fl uttered (so the problem may be resolved) by
checking all the servo grommets for deterioration or signs of
vibration. Make certain all pushrod linkages are secure and
free of play. If it fl uttered once, under similar circumstances
it will probably fl utter again unless the problem is fi xed.
Some things which can cause fl utter are; Excessive hinge
gap; Not mounting control horns solidly; Poor fi t of clevis
pin in horn; Side-play of wire pushrods caused by large
bends; Excessive free play in servo gears; Insecure servo
mounting; and one of the most prevalent causes of fl utter;
Flying an over-powered model at excessive speeds.

20

Takeoff

The Pluma 3D ARF can take off from the ground (ROG)
or can be hand launched. Rise-off-ground (ROG) takeoffs
should be reserved for indoor fl ying and should be performed
with the model rolling away from you and others. For your
fi rst fl ight it’ s probab ly a good idea to have an assistant hand­launch the plane for you. You should be ready to correct (or fl y
through) any trim errors. First, set your transmitter for LOW
RATES. Launch your plane directly into the wind (and away
from others). After your assistant launches the plane, have
him come back and adjust the trim on your transmitter. If
you want to perform an ROG takeoff, make sure the surface
you’re using is completely smooth and free from “potholes”
that can fl ip the plane or break the landing gear.

Flight

When you’re airborne and your plane is trimmed out,
throttle back and fl y the pattern. Get used to the way the
model handles with standard control inputs. When you’re
comfortable, try switching to HIGH rates to see how you
like the plane (save 3D rates for later fl ights). Based on your
preference, you ma y w ant to adjust y our rates or e xponential
settings in your radio. If your assistant is still available, have
him take notes for you so you can make adjustments when
you land. Fly around f or a bit and try a few simple maneuv ers
like: slow fl ight, gentle rolls, loops, stalls, and hammerhead
stalls. Practice a few landing approaches.

Have a ball! But always stay in control and

fl y in a safe manner.

GOOD LUCK AND GREAT FLYING!

Make a copy of this identifi cation tag and put it on or
inside your model.

FROM GREAT PLANES

Landing

Before you land, throttle down completely (with a safe
amount of altitude). You’ll notice that when you power off,
the airplane will lose speed very quickly but will not pitch
down. To keep your speed up you’ll have to pitch do wn rather
steeply and this can be less than ideal for most landings. Set
up for landing by throttling down to an “idle” instead. If you
fi nd it diffi cult to get the right setting, power-off completely
and try blipping the throttle. For a short approach, power-off
completely while at altitude and pitch down. At the fl are, be
ready to blip the throttle for a gentle 3-point landing.

One fi nal note about fl ying your model: Have a goal or fl ight
plan in mind for every fl ight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to
improve your skills (though it is never a bad idea!), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly fi nding that you’ve
run out of time, altitude or airspeed. Every maneuver should
be deliberate, not impulsive. A fl ight plan greatly reduces
the chances of crashing your model just because of poor
planning and impulsive moves. Remember to think.
