❍ (4) 6" [150mm] universal servo extensions (TACM2092)
are required for the ailerons (one on each servo and
one in each channel in the receiver).
If powering your Uproar V2 with a glow engine, a receiver
battery and on/off switch will also be required:
❍ Hobbico 2S 6.6V 1300mAh LiFe battery (HCAM6411)
❍ On-off receiver switch (TACM2000)
Glow Engine
The Uproar V2 is suited for a .46 2-stroke glow. The O.S.
Max .46AXII ABL (OSMG0548) is illustrated in this manual.
Other accessories for a glow engine
❍ 1/4" [6.4mm] R/C foam rubber (HCAQ1000)
❍ Fuel tubing (GPMQ4131)
❍ Suitable propeller for your engine
A minimum of 4-channels is required to y the Uproar V2 ARF.
The Tactic TTX650 transmitter is recommended because
of its simple, exible computer programming and multiple
model memory:
❍ Tactic TTX650 6-channel programmable radio
(TACJ2650)
❍ Tactic TR625 6-chanel receiver (TACJ0625)
❍ Tactic TSX25 mini digital high-speed 2 ball bearing
servos offer the most precision (TACM0225), but
Tactic analog servos are also suitable (TACM0220).
Four servos are required for a brushless setup and
ve servos for glow.
Brushless Electric Motor
The electric setup for the Uproar V2 is straightforward: a
Great Planes Electri y RimFire .32 on a 13 x 8 E prop with a
80A ESC powered by a 4S 3800mAh LiPo. A Hitec Energy
Sport 80 ESC is illustrated in the instruction manual. A 14 x
7E prop is also suitable.
❍ 42-50-800 RimFire .32 (GPMG4700)
❍ APC 13 x 8 thin E prop (APCQ3080)
❍ APC 14 x 7 thin E prop (APCQ4145)

❍ Venom Fly 4S 3600 mAh 30C (VNRA2516)
2
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.
Adhesives, Hardware &
Other Accessories
A covering iron with a cover sock may be required for
tightening and re bonding the covering to the model that may
have loosened between the time the plane was manufactured
and the time the model was removed from the box. The 21st
Century iron is preferred because of its long cord, contoured
shoe and precisely adjustable temperature range:
❍ Coverite 21st Century Sealing Iron (COVR2700)

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 21st Century cover iron
with a cover sock set to about 360 – 375F [180 – 190 C].
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.
4
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.
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.
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.
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).
5
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.
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.
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.
6
5. After the CA has hardened ex the aileron up and down
2

❏
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.
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 subtrims in your transmitter programming. Fit a servo arm to
the servo that will be perpendicular to the servo as shown.
3. Fit the servo into the wing and drill 1/16" [1.6mm] holes
❏
for the servo mounting screws.
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).
7
6. Thread a 4" [100 mm] pushrod onto a clevis until a small
90-Degree
Pushrod
Connector
1/16" [1.6mm ]
❏
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.
9. With the aileron and servo arm centered, mark the
❏
pushrod where it crosses the hole in the servo arm.
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 M 2.5 x 15 Phillips wood screws and the horn
backing plate on the top of the aileron.
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.
8
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.
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.
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.
5. Slide both wings all the way onto the fuselage.
