INTRODUCTION
Your new ProX260 ARF-QB is a highly aerobatic airplane. It is capable of both precision
and 3-D maneuvers. The aircraft builds easily, quickly, and precisely due to its state of the
art CAD design, LASER cut technology, and high quality included hardware. We hope you
enjoy building and flying your ProX260 ARF-QB.
Great care has been taken in both the design and manufacturing of the ProX260 ARF-QB to
allow for the strongest and lightest construction possible. Only the highest quality materials
from the covering, paint, wood and hardware have been used in the construction of this
model.
The ProX260 ARF-QB has been individually hand built, covered and painted by trained and
experienced craftsmen with over 25 years of manufacturing experience. Using CAD design,
laser cut technology and jig-built assures accuracy in all stages of production.
The ProX260 ARF-QB is designed for glow engines. The OS engines shown in the assembly
are available from Aeroworks. The 46-60 ProX260 Was tested with an OS 55AX and the 60-
90 ProX260 was tested with an OS 75AX. Both have outstanding performance. The final
choice of engine is left up to the builder. A computer radio is recommended to allow the pi-
lot to take advantage of the full capabilities of this aerobatic aircraft.
IMPORTANT Please read through this manual carefully, before starting the assembly of
your new ProX260 ARF-QB . Inventory and inspect all parts and hardware for any imper-
fections or damage. Notify Aeroworks immediately if there are missing or damaged
parts. INTENDED USE

1. Open your kit slowly and take care not to dam-
age any parts of the kit. Remove all parts from
their plastic protective covers for inspection.
Before doing any assembly or installation of any
decals it is very important to re-shrink or re-
tighten the already applied covering. Due to the
shipping process, heat and humidity changes
from different climates, the covering may be-
come lose and wrinkle in the sun. If you take the
time to re-tighten the covering, you will be re-
warded with a long lasting beautifully covered
model.
TIGHTENINGAND RE-SHRINKING THE COVERING
2. Using your covering iron with a soft sock, gently
apply pressure and rub in the covering. If any
bubbles occur, your iron may be to hot. Reduce
heat and work slowly.
3. If bubbles persist, use a small pin to punch holes
in the bubble to relieve trapped air and reheat.
4. Use your heat gun with extreme caution. Take
care not to apply too much heat to one area for
long periods of time. This may cause the trim
colors to over shrink and pull away leaving un-
sightly gaps on the color lines. The trim stripes
are especially vulnerable to over shrinking.
5. Your model is covered with Ultracote™ cover-
ing. In case of repairs, the colors are:
Yellow/Red Scheme
True Red #866
White #870
Bright Yellow #872
Orange/Blue Scheme
Midnight Blue #885
White #870
Orange #877
Tightening and re-shrinking the covering is a
never ending process and needs to be
checked after each flying secession.

12
1. Go over all seams and color overlaps with your
sealing iron.
Note: Even if your models covering has no wrin-
kles out of the box it is still very important to go
over all seams and overlaps to make certain they are
sealed securely. This is especially important at the
leading edges of the wings and stabs. We recom-
mend checking the covering after each flying ses-
sion.
CHECKING SEAMS AND COLOR OVERLAPS FOR GOOD SEAL
2. Use your covering iron to ensure all edges,
seams, and color overlaps are securely sealed.
IMPORTANT:
It is the purchaser / user responsibility to
check the covering seams and overlaps for se-
curity and a good seal. Aeroworks is not re-
sponsible for failure of covering seams or over-
laps during flight.
This is a never ending process that must
be done after each flying secession. Due to
varying temperatures and humidity changes
from day to day the covering will continue to
loosen and must be maintained.
3. Use your covering iron to ensure all edges are
securely sealed. Do not use a heat gun in this
area as it will cause the covering to pull away
from the cut out area.

13
Aileron/Servo Installation
The ailerons and wings come pre-hinged but are
not glued. The builder must glue the hinges in
place using thin CA.
1. Center the hinge in the pre-cut hinge slot us-
ing T-pins. Make sure that the hinge is
straight to prevent binding.
WINGASSEMBLY
2. After all 5 CA hinges have been placed in the
wing slide the aileron onto the hinges. Once
again it is very important that the hinge stay
straight.
3. Use a straight edge to make sure that the aileron
sits flush with the wing-tip.
4. Remove the T-pins from each hinge. Using a
new bottle of thin CA apply 3-4 drops on each
side of the hinge. Be careful not to over soak the
hinges with CA this can cause failure.
Note: Always use a fresh bottle of CA. Old CA will
not cure and can cause failure.

14
5. Install the brass servo eyelets in the servos with
the flanges towards the top of the case as shown
below.
Note: Trim the servo mounting screws to ensure
they will not
pass through the
top of the wing
when installed.
6. Install servo in the servo bay inside the wing.
Ensure that the output shaft is towards the trail-
ing edge of the wing.
7. Ensure the output shaft is centered in the hole as
shown.
Control Horn Installation
1. Gather the aileron control horn parts as shown
below.
◊ 2 - Nylon control horns
◊ 2 - Base plates
◊ 4 - 2x25mm Phillips head mounting bolts.

15
2. Place the control horn over the predrilled mount-
ing holes.
3. Use a Phillips screw driver to install the 2 con-
trol horn mounting bolts through the aileron.
4. Thread the two mounting bolts into the control
horn base plate on top of the aileron. Be careful
not to over tighten as this could crush the sheet-
ing.
5. Use a pair of wire cutters to trim the excess bolts
from the top of the wing.

16
6. Use a small flat stick, an epoxy stir stick works
well, to keep the ailerons in the neutral position
as shown.
.46-.60 Pushrod Assembly
1. Gather the following items for the .46-60 size
model shown below:
◊ 2 - 2-56 Pushrods
◊ 2 - 2-56 threaded metal R/C links
◊ 2 - nylon keepers
3. At the location marked in the previous step make
a 90 degree bend in the pushrod. Remove the
excess rod with a pair of wire cutters. Install the
pushrod through the servo arm and into the ny-
lon keeper.
2. Install the pushrod onto the nylon control horn
using the supplied R/C Link. Center all servos
using the radio, leave the radio on until you have
clearly marked the pushrod. Using a felt-tip pen
mark the location for the 90 degree bend on the
push rod.

17
4. Final servo installation shown below. Be sure to
use a piece of fuel tubing over the clevis to keep
it secure.
.60 -.90 Pushrod Assembly
1. Gather the following items for the .60-.90 size
model shown below:
◊ 2 - 4-40 Pushrods
◊ 4 - 4-40 threaded metal R/C links
◊ 4 - 4-40 Lock nuts
2. Final servo installation shown below. Be sure to
use a piece of fuel tubing over the clevis to keep
it secure.

18
Stab/Elevator Installation
1. Slide the horizontal stabilizer into the pre-cut
slot in the fuse. Use a ruler to center the stab
from the back like shown below.
3. Ensure the ailerons are centered with the wing, it
may be necessary to tape them in place. Adjust
the stab so it is centered left to right in the fuse
and is pushed all the way forward. Measure from
the wingtips to the corner of each side of the
stab, adjust the stab until these distances are
equal. This ensures the stab is square with the
wing.
2. Install the wing and check the alignment of the
stab to the wing. 4. Use medium size binder clips to help hold the
stab in place once the correct position is found.
Note : Take care not to crush or damage the
stabilizer with the binder clips.

19
5. Use a pen to lightly mark the stabs position in
relation to the fuse on both top and bottom.
6. Mix 30 Minute Epoxy and brush onto the ex-
posed wood in the center of the stab. Make sure
to use epoxy on both top and bottom.
7. Insert stab back in fuse and double check align-
ment. Allow the Epoxy to dry before continuing.
Note: Clean off excess epoxy using rubbing
alcohol.
Note: Make certain the stab is pushed all the way
forward
8. Pin each CA hinge using the same method that
was used for the wings.
9. Install the hinges into the stab and elevator and
remove the pins. Use thin CA to glue the hinges
in place.
Note: Always use a fresh bottle of CA. Old CA will
not cure and can cause failure.

20
1. Mix 30 Minute Epoxy and brush onto the ex-
posed portion of the rear post and reinforcement
tab on the vertical fin as shown.
VERTICAL FIN/RUDDER INSTALLATION
(.46-.60 Tail Wheel Installation)
2. Insert vertical fin back in fuse and double check
alignment. Allow the Epoxy to dry before con-
tinuing.
Note: Clean off excess epoxy using rubbing
alcohol.
46-60 SIZE ONLY
3. Use 30minute epoxy to secure the steering arm
inside the precut slot in the rudder as shown.
Note: If building the .60-.90 size ProX260 skip to
step 4
4. Pin each CA hinge using the same method that
was used for the wings.
5. Install the hinges into the rudder and vertical fin
and remove the pins. Use thin CA to glue the
hinges in place.
Note: Always use a fresh bottle of CA. Old CA will
not cure and can cause failure.
