INTRODUCTION
Congratulations and thank you for purchasing the Tower
Hobbies Uproar V2 ARF. The Uproar V2 is an exciting, updated
version of the original Uproar ARF. If you’re a casual sport
pilot, the Uproar V2 can be tamed simply by switching to
“normal” or low-rate control throws. Then it becomes a docile
every day sport yer.
For the latest technical updates or manual corrections, nd

LiPo Battery Charger
To charge a 4S 3800mAh LiPo at 1C a charger capable of
at least 65 Watts output power is required (4S x 4.2V/cell
= 16.8V x 3.8A = 63 Watts). The Triton EQ2 (GPMM3156) is
more than enough charger with 100W output AC and 120W
output DC.

PREPARATION
The covering on film-covered ARFs typically requires
retightening and rebonding to the structure underneath from
wrinkles that may appear between the time the covering was
applied and the time the kit arrived in your hands. The best
way to renew the covering job is with a covering iron with a
protective cover sock. We prefer a 21
st
Century cover iron
with a cover sock set to about 360 – 375F [180 – 190C].
You may nd this is a little hotter than the temperature you
use on other coverings, but this material seems to require
more heat. The recommended temperature setting translates
to about 340F measured on the surface of the cover sock.
❏
1. Glide the iron over unsupported lm, but where the
lm is over wood apply pressure to bond the covering to the
wood. In some areas the wood will bow or bend inward, so
wherever possible, support the structure underneath with
your other hand. Adjust the heat setting as needed.

❏
2. Optional: Three or four pinholes can be punctured
through the covering between each rib in the bottom of
the horizontal stabilizer, the elevators and ailerons, and in
one side of the vertical stabilizer and rudder. This will allow
heated, expanding air to escape while tightening covering.
These pinholes may appear obtrusive at rst, but when the
covering is heated they virtually disappear (plus, most of the
pinholes will be on the bottom). Heat the side of the covering
without the pinholes rst.
❏
3. Stack a few paper towels on top of each other and cut
them into small squares. These small paper towel squares
come in handy for dabbing up excess CA or wiping up epoxy
when dampened with denatured alcohol.
❏
4. NOTE: All machine-thread screws that thread into metal
(hex nuts, blind nuts, wheel collars, etc.) should be lightly
wetted with threadlocker.
❏
5. NOTE: The procedure for preparing the holes in wood
for all wood screws is as follows:
A. Drill the hole with the drill speci ed in the step.
B. Install, then remove the screw to “set” the threads.
C. Add a drop or two of thin CA to harden the threads in
the hole.
D. Allow the CA to harden, then install the screw(s) with
whatever it is that is being mounted/installed/attached
(servos, landing gear, etc.).
ASSEMBLE THE WING
Hinge the Ailerons
The left wing is shown in the images, but both wings could
be assembled simultaneously.
❏
1. If not yet done, separate the aileron from the left wing
and tighten the covering as previously described (the pinhole
technique works well for the ailerons).
6
❏
2. Cut the covering from the servo mount in the bottom of
the wing – you may simply cut the covering along the edges,
or cut 1/8" [3mm] inside the edges, then seal down inside
with a trim iron.
❏
3. Rejoin the aileron to the wing with the hinges – as you
close the hinge gap make sure the hinges remain centered
and make sure the tip of the aileron is even with the tip of
the wing.
❏
4. Using a CA tip on a bottle of thin CA, apply ve or
six drops to the top and bottom of each hinge – wait a few
seconds between drops for the CA to soak in. And keep
those small paper towel squares handy. They can be touched
edge-wise to the hinges to absorb excess CA before it wicks
along the hinge gap.
7
❏
5. After the CA has hardened ex the aileron up and down
and pull hard to make sure the hinges are secure.
Continue with this wing, or go back to step 1 and hinge the
other aileron.
Hook Up the Ailerons
❏
1. Attach a 6" [150mm] servo extension to the aileron servo.
❏
2. Use 1/2" [13mm] heat shrink tubing, tape or a dab of
glue to secure the connections.
❏
3. Fit the servo into the wing and drill 1/16" [1.6mm] holes
for the servo mounting screws.
2
1
3
4
90
❏
4. Connect the servo to your receiver with a battery so you
can power the servo with the radio. Turn on the transmitter
and the receiver. Don’t forget to center the trims and sub-
trims in your transmitter programming. Fit a servo arm to
the servo that will be perpendicular to the servo as shown.
❏
5. Cut off the unused servo arms and use a #49 (.073")
drill to enlarge the holes in the remaining arm. (Even though
the pushrod wire measures .070" in diameter, a .073" drill
sizes the holes correctly because the plastic expands when
drilling the holes.) If you prefer, you may use a sanding drum
to trim the remainder of the cut-off arms (as was done for
the servo arm in the photo).
8
❏
6. Thread a 4" [100 mm] pushrod onto a clevis until a small
portion of the threads appear through the clevis as shown.
❏
7. Connect the clevis to the middle hole in a control horn
and secure with a silicone retainer.
❏
8. Set the horn on the aileron so the pushrod will be in
alignment with the second from the outer hole in the servo
arm (about 1/2" [13mm] out from center) and the clevis
holes in the horn will be centered over the leading edge of
the aileron. Using the holes in the horn as a guide, drill 3/32"
[ 2.4mm] holes through the aileron. Mount the horn to the
aileron with two M2.5 x 15 Phillips wood screws and the horn
backing plate on the top of the aileron.
❏
9. With the aileron and servo arm centered, mark the
pushrod where it crosses the hole in the servo arm.
90-Degree
Pushrod
Connector
1/16" [1.6 mm]
❏
10. Make a 90-degree bend in the wire at the mark, connect
the pushrod to the servo arm with a 90-degree pushrod
connector, and then cut off the excess wire.
❏
11. As noted and pictured on page 5, remove the servo
mounting screws and temporarily remove the servo from the
wing. Add a drop or two of thin CA to each screw hole, and
allow the CA to harden. Then, re-mount the servo.
❏
12. Power the servo again with your radio. If necessary,
remove the servo arm and thread or unthread the pushrod
from the clevis so the aileron will be centered when the servo
is centered. Reconnect the servo arm and fasten with the
servo arm screw that came with the servo.
9
❏
13. While the servo is still operational move the aileron
up and down to check for smooth movement. Make any
adjustments necessary.
❏
14. Prepare the other wing with the aileron servo the
same way.
ASSEMBLE THE FUSELAGE
Prepare the Fuselage for the Stab & Fin
❏
1. If you haven’t yet done so, address any covering issues
on the fuselage and the tail parts as described on pages 4
and 5.
❏
2. Cut the covering from the fuselage over the rudder
pushrod exit and both elevator pushrod exits and from the
stab and n slots. Remove the temporary ller block from
the stab slot.
❏
3. Also cut the covering from both sides over the wing
tube holes, the alignment peg holes, the slots for the wing
retainers and for the aileron servo wires.
❏
4. Cut the covering from the stab for the slot for the n
post and from the bottom of the n where shown, being
cautious not to cut into the wood.
❏
5. Slide both wings all the way onto the fuselage.
10
❏
6. Test t the n and stab into the fuselage.
❏
7. View the model from behind to see if the stab is parallel
with the wing. If it is not, sand the bottom of the stab saddle
on the high side of the stab and the top of the saddle on
the low side until the stab aligns with the wing – it shouldn’t
take much sanding and proceed in small increments. Once
the saddle is adjusted all that should be required is a small
amount of weight to hold down the high side.
Trailing Edge of
Vertical Stabilizer
and End of
Fuselage Align
❏
8. Make certain the trailing edge of the vertical stabilizer
aligns with the aft end of the fuselage. Otherwise the leading
edge of the rudder will not contact both parts, causing a
hinge gap.
❏
9. The stab is pretty much locked-in and self-aligned
with the fuselage, but there is a little free-play. If striving for
perfection, you could rotationally align the stab as follows:
A. Tie a loop around one end of an approximately 48”
[1200mm] non-elastic line. Fold a piece of masking tape
over the other end of the line. Mark a line on the tape.
B. Insert a pin into middle of the lip in the front of the fuselage
for the battery/fuel tank hatch. Loop the line over the pin.
11
C. Hold the line with the tape to one corner of the stab.
Swing the line over to the corner on the other end of the
stab. Adjust the stab and slide the tape along the line until
the stab is centered and equalized.
❏
10. Use a ne-point felt-tip pen to mark the base of the
n onto the top of the fuselage.
❏
11. Also mark the top and bottom of the fuselage onto the
top and bottom of the stab.
❏
12. Cut the covering from the top of the fuselage
approximately 1/16" [1.6mm] inside the n marks, being
cautious not to cut into the wood. Wipe away the ink lines
with a paper towel square dampened with denatured alcohol.
Then, remove the covering.
12
❏
13. Use a pin to puncture the covering on both sides of the
stab just inside the lines you marked. Wipe away the ink lines
with a paper towel square dampened with denatured alcohol.
❏
14. Finally, cut and remove a strip of covering from the top
of the stab in alignment with the slot for the n post.
Glue in the Horizontal & Vertical Stabilizers
❏
1. Gather your small paper towel squares and denatured
alcohol for epoxy clean up. Small balsa sticks chopped up
from 1/16" [1.5mm] balsa sheet are also handy for wiping
away most of the epoxy before using the paper towel squares.
❏
2. Mix up approximately 1/4 oz. of 30-minute epoxy. Apply
epoxy to the top and bottom of the stab over the pinholes
aligned with the fuselage sides and to all other joining parts
of the fuselage and n.
❏
3. Slide the stab into position, then add the n. If you’ve
cut up balsa sticks, use them to wipe away most of the epoxy
followed by paper towel squares dampened with denatured
alcohol. Double-check alignment, place the weight on the
stab if used and allow the epoxy to harden.
❏
4. After the epoxy has hardened remove the wing to
proceed with assembly.
Install the Receiver Battery
Skip this section if using a brushless motor and powering
the radio with a BEC or voltage regulator.
If installing the receiver battery in the location shown, this
must be done before the elevator and rudder pushrods have
been installed.
13
❏
1. Tape a layer of 1/4" RC foam around your receiver battery.
❏
2. Some glow engine installations may require tail ballast,
so it is desirable to mount the battery as far back as practically
possible which is why the location illustrated in this manual
was chosen. Install the battery, then hold it into position
with pieces cut from the 1/4"x 1/2" x 4" [4 x10 x100 mm] balsa
stick as shown.
Attach the Elevator and Rudder
❏
1. Cut the covering from the hinge slot in the end of the
fuselage and test- t a CA hinge. If the hinge ts too tight,
enlarge the slot a little with a hobby knife or a small razor
saw blade.
❏
2. Applying the same procedures used for hinging the
ailerons to the wings, join the elevators to the stab with the
hinges and permanently glue them in with thin CA. (If you’ve
poked pinholes in one side of the covering over the elevators
be sure to put those sides down.)
❏
3. Make both elevator pushrods the same way you
made the aileron pushrods; thread the clevises onto two
27-3/4" [705mm] threaded one end pushrods, connect
the clevises with silicone retainers to the pushrods and
connect the clevises to the second-from-the-outer holes
in the control horns.
22-1/4" [570mm]
❏
4. Cut both pushrods to a length of 22-1/4" [570 mm] from
the retainer screw to the end of the pushrod. Save one of
the pieces of wire you cut off.
❏
5. Insert the pushrods into the elevator guide tubes in the
fuselage and mount the horns to the elevators the same way
you did the aileron horns (drill 3/32" [2.4mm] holes and use
M2.5 x 15 wood screws and the horn back plates on the top
of the elevators).
14
❏
6. Temporarily t the rudder to the n and fuselage with
the hinges. Make the rudder pushrod the same way you
made the elevator pushrods, but don’t cut the wire. Slide
the pushrod into the fuselage, align the horn over the rudder
and mark the location of the screw holes.
❏
7. Remove the rudder and pushrod and leave the hinge
nearest the horn in the rudder. Drill the holes through the
rudder for the screws – if the holes intersect the hinge, just
drill through the hinge.
❏
8. Mount the rudder horn to the rudder (with the hinge
in place), t the rudder back to the fuselage and glue in the
hinges with thin CA.
❏
9. After the CA on all the hinges has hardened, ex the
elevators and rudder up and down and pull on them to make
sure they are secure.
Hook Up the Elevator and Rudder
❏
1. Use the wire you saved from cutting the elevator
pushrods to make a short pushrod with an L-bend for a
pushrod keeper as shown.
Refer to this image for the following three steps.
❏
2. Place the elevator and rudder servos in the servo tray as
shown, but do not mount the servos until instructed to do so.
❏
3. Hook up the rudder and elevators with the same
techniques used for the ailerons (centering the servos with
the radio on, nding the servo arm 90-degrees to each servo,
cutting off the unused arms, drilling out the holes with a #49
[.073"] drill and connecting the pushrods to the servos with
90-degree pushrod keepers). Install, but do not tighten the
set screws on the elevator pushrod link.
❏
4. With all the pushrods connected, position the servos
as shown with a little space between the rudder pushrod
and the elevator pushrod link so they will not interfere with
each other. Drill 1/16" [1.6mm] holes through the servo tray
for mounting the servos. Mount the servos with the mounting
screws that came with them (don’t forget to harden the screw
holes with thin CA).
❏
5. Adjust the clevis on the rudder pushrod so the rudder
will be centered when the servo arm is centered.
15
❏
6. To adjust the elevator pushrods and tighten the elevator
pushrod link, again with the radio on and the servo powered,
use a 1.5mm hex driver to rst tighten the middle set screw
locking the pushrod link to the pushrod. Using a straightedge
to hold one of the elevators at with the stab, tighten the
corresponding set screw in the link to lock the pushrod down.
Then, tighten the other set screw for the other pushrod the
same way.
❏
7. Use the radio to move the elevators up and down
observing the pushrods and the pushrod link to make
sure everything operates smoothly. Make any adjustments
necessary.
We’ll mount the on/off switch (if used) and receiver after the
engine/motor has been mounted.
INSTALL THE POWER SYSTEM
Mount the Brushless Motor
Skip to page 16 if installing a glow engine.
❏
1. Push a pin or a small nail into the four “X” marks
in the firewall that mark the location of the holes for the
mounting screws.
❏
2. Drill 1/16" [1.6 mm] pilot holes through the “X” marks.
Then, enlarge the holes with a 5/32" [4 mm] drill.
❏
3. Cut and remove the piece from the firewall for the
motor wires.
❏
4. Mount the motor to the rewall with M3 x 15 button-
head screws, M3 lock washers and at washers and M3
blind nuts in the back of the rewall.
16
❏
5. Apply a strip of the rougher, “hook” side of adhesive-
back hook-and-loop material (not included) to the top of the
battery tray and apply a strip of the softer, “loop” side to the
bottom of your battery.
❏
6. Cut a strip of hook-and-loop strap material (not included)
to the correct length for a battery strap to hold your battery
to the battery tray.
❏
7. Mount the battery tray in the battery compartment with
four M3 x 10 button-head Phillips screws. Glue two 12 x 12
x 12 mm balsa blocks to the back of the rewall to prevent
the battery from contacting the motor shaft that protrudes
out the back of the motor.
❏
8. Connect the ESC to the motor and place the ESC in
the compartment aft of the battery compartment ahead of
the wing tube. Guide the signal wire from the ESC over the
wing tube into the radio compartment.
❏
9. Test- t the battery in the battery compartment. Arrange
the battery wires and make any adjustments necessary.
Skip ahead to Final Radio Installation on page 20.
Mount the Glow Engine
For C.G. purposes, it is desirable to position the glow engine
as far aft on the engine mount as possible. This will minimize
(or possibly eliminate) any tail ballast that may be required.
❏
1. Push a pin or a small nail into the four “+” marks
in the rewall that mark the location of the holes for the
engine mount screws.
17
❏
2. Drill 1/16" [1.6 mm] pilot holes through the “+” marks.
Then, enlarge the holes with a 3/16" [5mm] drill.
❏
3. Press M4 blind nuts into the holes in the back of
the firewall.
❏
4. Temporarily fasten the engine mounts to your engine
with a M3 x 25 SHCS (with M3 lock washers and at washers)
through the front holes in the engine mount lugs and the
rear, elongated holes in the engine mounts. Do not tighten
the nuts all the way.
❏
5. Temporarily mount the engine mount with engine to
the rewall with four M4 x 25 Phillips screws and M4 lock
washers and at washers. Use a Great Planes Dead-Center
hole locator to mark the rear engine mount screw holes onto
the engine mount.
❏
6. Before removing the engine from the mount to drill the
rear two mounting screw holes, sight-down a location on
the rewall for the throttle pushrod and guide tube. There
is already another “+” mark for the O.S. .46, but if using a
different engine you may have to mark the hole in another
location on the rewall. Be certain the hole will not interfere
with the blind nuts for the engine mount bolts or with the
fuel tank once installed.
18
❏
7. Remove the engine from the engine mount. You may also
remove the mount, or leave it in position. Drill 1/16" [1.6 mm]
pilot holes through the marks you made for the rear engine
bolts. Then, enlarge the holes with a 1/8" [3.2mm] drill.
❏
8. Drill a 3/16" [4.8 mm] hole through the rewall for the
throttle pushrod guide tube at the “+” mark (or at another
location previously marked.)
❏
9. Mount the engine to the engine mount with all four M3
x 25 SHCS and washers and M3 lock nuts.
Hook Up the Throttle
❏
1. Guide the throttle pushrod guide tube through the hole
you drilled in the rewall, through the hole in the former in the
fuel tank compartment and up to the throttle servo location.
Cut the guide tube to the correct length, then glue it into
place. See the pictures on the next page for reference.
❏
2. Mount the throttle servo to the throttle servo mount.
❏
3. Fit, then glue the throttle servo mount into position.
❏
4. Fasten the screw-lock connector to the throttle servo
arm – use threadlocker to tighten the double nuts to each
other, but not to the servo arm. This way, the screw-lock
connector will be able to pivot as the servo arm rotates.
19
❏
5. Install and cut the throttle pushrod to the correct length.
Then, connect it to the carburetor arm and the screw-lock
connector on the servo arm.
❏
6. You can set up the throttle now or later to open and
close the carburetor barrel on the engine with the throttle
stick on the transmitter. When ready to lock the pushrod to
the screw-lock connector, use a 2.0 mm hex driver on the
set screw and hold the screw-lock body with pliers so the
set screw can be tightened thoroughly.
Install the Fuel Tank
❏
1. Fit a 3" [ 75 mm ] piece of medium fuel line (not included)
onto the straight pickup tube in the fuel tank stopper. Then,
add the clunk to the line.
❏
2. Fit the stopper assembly into the tank with the vent
tube pointing toward the top of the tank as shown. Tighten
the screw to compress the stopper and seal the tank.
❏
3. Test-mount the tank to the fuel tank/battery tray with
a piece of 1/4" [6.5mm] RC foam rubber in-between and
two 10" [250mm] straps cut from a piece of Great Planes
hook-and-loop strap material (not included).
20
❏
4. You may tape the straps across the bottom of the tray
so they won’t fall off, then remove the tank and install the tray
in the fuselage with four M3 x 10 button-head Phillips screws.
❏
5. Install and tightly strap the tank down – the straps
should be tight to compress the foam enough so the top
of the tank will not interfere with the hatch. Connect a fuel
line from the pickup tube in the fuel tank to the carburetor.
Connect another fuel line to the vent tube that will later be
connected to the pressure tting on the muf er.
Final Radio Installation
❏
1. If using an on/off switch for your receiver (for glow engine
installations) plan the location and installation of the switch.
Be sure the switch is in a location that will not interfere with
anything internally and will not get coated with fuel or exhaust.
Use the switch mounting plate as a template for cutting the
slot and for drilling the holes for the switch.
❏
2. Connect 6" [150 mm] servo extensions to the receiver
for the aileron servos. Then, use adhesive-back hook-and-
loop strips (not included) or other preferred method to mount
the receiver. Connect the servo wires and the on/off switch.
❏
3. Position and secure the receiver antennas according
to the speci cations of the receiver. For the Tactic receiver
shown, the antennas are to be positioned 90-degrees to
each other, so small pieces of plastic tubing (such as from an
aerosol spray can) were glued to the fuselage in the proper
orientation and the antennas were held inside the tubes.
FINAL ASSEMBLY
Mount the Main Landing Gear
❏
1. File at spots on the back-side of the landing gear for
the screws in the wheel collars.
❏
2. Use a collar with an M3 x 5 Phillips screw on both sides
of the wheels to hold the wheels to the gear.
