SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your model airplane 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, this model, 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 un yable model. In a few 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 rst-class
condition.
5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and
in the air.
6. You must check the operation of the model before every
ight to ensure that all equipment is operating and that
the model has remained structurally sound. Be sure to
check clevises or other connectors often and replace
them if they show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not own this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your rst 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. IMPORTANT: While this ARF has been ight tested to
exceed normal use with the recommended power system
components, the structure of the plane was purposely
designed to be lightweight. This results in a plane that
is not as durable as most models. Also, be careful when
handling the plane. We recommend that you do not y
at full throttle and apply full 3D throws. This plane will
perform excellent 3D maneuvers ying slowly.
We, as the ARF manufacturer, provide you with a top
quality, thoroughly tested plane and instructions. But,
ultimately the quality and yability of your 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.
As the user of this product, you are solely responsible for
operating in a manner that does not endanger yourself and
others or result in damage to the product or the property
of others.
● Always keep a safe distance in all directions around
your model to avoid collisions or injury. This model is
controlled by a radio signal subject to interference from
many sources outside your control. Interference can
cause momentary loss of control.
● Always operate your model in open spaces away from
full-size vehicles, traf c and people.
● Always carefully follow the directions and warnings for
this and any optional support equipment (chargers,
rechargeable battery packs, etc.).
● Always keep all chemicals, small parts and anything
electrical out of the reach of children.
● Always avoid water exposure to all equipment not
speci cally designed and protected for this purpose.
Moisture causes damage to electronics.
● Never place any portion of the model in your mouth as
it could cause serious injury or even death.
● Never operate your model with low transmitter batteries.
● Always keep aircraft in sight and under control.
● Always use fully charged batteries.
● Always keep transmitter powered on while aircraft is
powered.
● Always remove batteries before disassembly.
● Always keep moving parts clean.
● Always keep parts dry.
● Always let parts cool after use before touching.
● Always remove batteries after use.
● Always ensure failsafe is properly set before ying.
● Never operate aircraft with damaged wiring.
● Never touch moving parts.

ELECTRIC MOTOR SAFETY PRECAUTIONS
WARNI NG : A spinning propeller has the potential to cause serious and permanent
injury to yourself and others.
WARNI NG : Once the motor batteries are connected, the propeller can start
spinning at any time. Make sure the fail safe is set on your radio to prevent the
motor from starting if the transmitter signal is lost.
WARNI NG : Stand clear of the propeller when handling the aircraft. Make sure the
aircraft is held securely until the battery has been disconnected.
ALWAYS
ALWAYS remove the propeller if the motor batteries will
be connected while working on your plane.
ALWAYS switch on the transmitter rst with the throttle
stick in the lowest position, then plug in the lipo battery,
then turn on the receiver.
ALWAYS unplug the motor batteries rst before switching
off the receiver then transmitter.
ALWAYS keep your fac e and bod y as well as all spectators
away from the plane of rotation of the propeller as you
run the motor.
ALWAYS 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.
NEVER
NEVER operate the motor in an area of loose gravel or
sand; the propeller may throw such material in your face
or eyes.
NEVER touch the motor during or right after operation.
The motor gets HOT!
NEVER switch off the transmitter with the motor batteries
plugged in.
NEVER reach through the arc of the propeller when
plugging the battery into the ESC.

LITHIUM BATTERY WARNING
This product uses a lithium polymer (LiPo) battery. Improper
handling could result in FIRE! A lithium battery re has the
potential to ignite surrounding areas and may cause property
damage or cause personal injury. For safe LiPo handling,
follow all of these guidelines:
MOST IMPORTANT! Never leave the battery or charger unattended during charging
or discharging.
WARNING: Read the entire instruction sheet included with your
motor batteries. Failure to follow the instructions could cause
permanent damage to the battery and its surroundings and cause
bodily harm!
ALWAYS
ALWAYS remove the motor batteries from the plane
when charging.
ALWAYS follow the charging instructions included with
your charger for charging LiPo batteries. LiPo batteries
can cause serious damage or re if misused.
ALWAYS use a LiPo-approved charger.
ALWAYS set the charger’s output volts to match the
battery volts.
ALWAYS charge a LiPo battery in a reproof location
away from combustible materials.
ALWAYS balance charge the battery.
ALWAYS store and transport LiPo batteries in a reproof
container away from combustible materials.
ALWAYS KEEP OUT OF THE REACH OF CHILDREN.
ALWAYS keep LiPo batteries out of the reach of animals.
A punctured battery may cause a re.
ALWAYS disconnect the battery and unplug the charger
after the charge is complete.
ALWAYS keep a supply of sand ac c essible when charging
a LiPo battery. Dumping sand on the battery will assist
in extinguishing a LiPo chemical re.
ALWAYS remove the batteries from the plane after a
crash. Set them aside in a safe location for at least 20
minutes. If the batteries are damaged in the crash, they
could catch re. If the battery starts to swell, quickly move
the battery to a safe location, preferably outside away
from combustible material. Place it in a bucket, covering
the battery with sand.
NEVER
NEVER use water to try and put out a LiPo re.
NEVER charge or use a battery that is deformed, bent,
crushed, swollen, or has any type of visible damage.
NEVER use a NiCd/NiMH peak charger to charge a
LiPo battery.
NEVER charge in excess of 4.20V per cell unless the
battery is rated for a higher voltage.
NEVER charge at currents greater than 1C unless the
battery is rated for a higher charge rate.
NEVER trickle-charge a LiPo battery.
NEVER allow the battery temperature to exceed 140
degrees F (60 degrees C).
NEVER disassemble or modify the pack wiring in any
way or puncture the cells, as this may result in a re.
NEVER discharge below 3.0V per cell.
NEVER charge the battery or set the charger on
combustible materials.
NEVER charge the battery inside a vehicle or in a location
that could be damaged in the event of a LiPo re.
NEVER put a LiPo battery in the pocket of any clothing.
NEVER charge the batteries in the plane. Disconnect the
batteries and remove them from the plane immediately
after landing.
NEVER allow the battery to short circuit by touching
exposed wires together. This may cause a re.
NEVER operate or store batteries below 40˚F or above
110 ˚ F (4 - 4 3 ˚C )

the transmitter.
Check the failsafe by switching off the transmitter
with the motor battery connected to the ESC and the
motor running at a slow speed. The motor must stop
running when the transmitter is switched off.
Onc e you have determined th at it is operating corre c tly,
switch off the receiver or unplug the motor battery

Balance the Model Laterally
38
1. With the wing level, have an assistant help you lift the
model by the propeller shaft and the bottom of the
fuse under the TE of the 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 laterally balanced will track better in
loops and other maneuvers.

Balance the Model C.G.
1. Mark the C.G location on the bottom of the wing 2-1/8" (54mm) to 3" (76 mm) from the leading edge.
2. With the plane ready to y, and the motor batteries installed but not plugged in, use a Great Planes C.G. Machine
or apply narrow (1/16" [1.5mm]) strips of tape at the front and rear C.G. locations. Lift the model between the strips
of tape with your ngers to check the C.G. location. Do not balance the model outside this C.G. range.
3. First, move the ight battery forward or aft
to adjust the C.G. location. If the plane still
balances outside the range use Great Planes
“stick on” weight (GPMQ4485) to balance
the plane. Place incrementally increasing
amounts of weight on the bottom of the
fuselage over the location where it would be
mounted inside until the model balances. A
good place to add stick-on nose weight is to
the rewall or inside the LiPo compartment.
Once you have determined if additional
weight is needed, permanently attach the
weight with glue or screws.
4. IMPORTANT: If you found it necessary to
add any weight, recheck the C.G. after the
weight has been installed.
CAUTION: DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE. A model that is not properly balanced may be
unstable and possibly un yable.

PREFLIGHT
Identify Your Model
You should always have your name, address, telephone
number and AMA number on or inside your model. It
is required at all AMA R/C club ying sites and AMAsanctioned ying events. Fill out the identi cation tag on
page 25 and place it on or inside your model. You must
also have your FAA number on your plane and accessible
without any tools.
Charge the Batteries
Always charge your transmitter batteries the night before
you go ying, and at other times as recommended by the
radio manufacturer.
NOTICE: Unless the instructions that came with your radio
system state differently, the initial charge on new NiMH
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 your choice.
If the initia l charge is don e with a fast-charg er the batterie s
may not reach their full capacity and you may be ying with
batteries that are only partially charged.
If using LiFe batteries in your transmitter, be sure to
follow the instructions included with the correct charger
designed to charge LiFe batteries.
Ground Check and Range Check
Follow the radio manufacturer’s instructions to groundcheck the operational range of your radio before the rst
ight of the day. This should be done once with the motor
off and once with the motor operating at various speeds. If
the control surfaces do not respond correctly, do not y!
Find and correct the problem rst. Look for loose servo
connections or broken wires, corroded wires on old servo
connectors, or loose motor connectors. Try relocating the
receiver antennas away from the motor battery or engine.

The Mini Uproar plane
was designed to provide
a smaller and more
economical version
of the very popular
Uproar V2 sport plane.
The design was then
refined to add a bit
more 3D avor. It is a
great little sport plane
that ies well on the 3s
and 4s packs that are
very common in the hobby. It has been own on batteries
from 1800 to 320 0 m A h. We like the balan ce of weight and
duration with 2200 mAh batteries. The CG range is very
wide and it will y very nicely at the forward balance point
with low control throw rates. However, you can crank up the
throws, move the CG back, and it becomes a very different
ying airplane. The pro le canopy/turtle deck is not only
for appearance, but also functionality. High alpha 3D ight
and knife edge are greatly enhanced with this canopy. In
3D mode, knife edge is easy and stable, and even knife
edge loops can be completed. Wing tip plates (side force
generators) are not needed! The suggested power system
provides fantastic performance on a budget.

CAUTION: (THIS APPLIES TO ALL R/C
AIRPLANES): If, while ying, you notice an alarming
or unusual sound such as a low-pitched “buzz,” this may
indicate control surface utter. Flutter occurs when a
control surface (such as an aileron or elevator) or a ying
surface (such as a wing or stab) rapidly vibrates up and
down (thus causing the noise). In extreme cases, if not
detected immediately, utter can actually cause the
control surface to detach or the ying surface to fail,
thus causing loss of control followed by an impending
crash. If utter is detected, slow the model immediately
and land as soon as safely possible. Identify which
surface 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
se cure and free of play. If it uttered once, under similar
circumstances it will probably utter again unless the
problem is xed. Some things which can cause utter
are: Excessive hinge gap; Not mounting control horns
solidly; Poor 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 ying an
over-powered model or at excessive speeds.
Takeoff
It is a good idea to have a timer set on your transmitter,
wrist watch or cell phone. We found that the plane can y
for 6 to 8 minutes or more on a 4S 2200 mAh LiPo battery.
Set the timer for 5 minutes for the rst few ights. When
26
Page 27
41
recharging the battery note how much capacity was put
back into the battery. To maintain the performance of
LiPo batteries, no more than 80% of the capacity should
be drained from the battery on a ight. Adjust the timer
as needed.
Before taking off, see how the model handles on the ground
by doing a few practice runs at low speeds on the runway.
Hold “up” elevator to keep the tail wheel on the ground.
If necessary, adjust the tail wheel so the model will roll
straight down the runway.
Remember to take off into the wind. When you’re ready,
point the model straight down the runway, hold a bit of
up elevator to keep the tail on the ground to maintain tail
wheel steering, and then gradually advance the throttle.
The plane does not need to gain much speed to take
off. So be prepared. One of the most important things to
re member with a ta il dragger is to always b e ready to app ly
right rudder to counteract motor torque. At this moment
it is likely that you will need to apply more right rudder to
counteract the torque. Be smooth on the elevator stick,
allowing the model to establish a gentle climb to a safe
altitude before turning into the traf c pattern. Once you
have the plane trimmed out and see how slow it ies, you
will nd yourself taking off in 5' to 10' [1.5m to 3m].
FLYING Continued
Flight
It is a good idea to have an assistant on the ight line with
you to keep an eye on other traf c. Take it easy with the
model for the rst few ights, gradually getting acquainted
with it a s you gain con dence. Adjust the trims to maintain
straight and level ight. After ying around for a while,
and while still at a safe altitude with plenty of battery
left, practice slow ight and execute practice landing
approaches by reducing the throttle to see how the model
handles at slower speeds. Add power to see how she
climbs as well. Continue to y around, executing various
maneuvers and making mental notes of what trim or C.G.
changes may be required to ne-tune the model so it ies
the way you like. Mind your ight time, but use this rst
ight to become familiar with your model before landing.
Make sure you have enough battery power remaining to
allow a second landing attempt in case you have problems
with the rst one.
Landing
To initiate a landing approach, lower the throttle while on
the downwind leg. Continue to lose altitude, but maintain
airspeed by keeping the nose down as you turn onto the
crosswind leg. Make your nal turn toward the runway (into
the wind), keeping the nose down to maintain airspeed and
control. We recommend landing on the high or low rates.
Do not try to land on 3D rates. Level the attitude when the
model reaches the runway threshold, modulating the throttle
as necessary to maintain your glide path and airspeed. If
you are going to overshoot, smoothly advance the throttle
(always ready on the right rudder to counteract torque).
Climb out to make another attempt. When the model is a
foot or so off the deck, smoothly increase up elevator until
it gently touches down. Once the model is on the runway
and has lost ying speed, hold up elevator to place the tail
on the ground, regaining tail wheel control.
FINAL NOTE: Have a goal or ight plan in mind e ach time
you y. This may be learning or improving a maneuver or
learning how the model behaves at certain speeds and
control rates. Every maneuver should be deliberate, not
impulsive. A ight plan reduces the chances of crashing
your model because of poor planning and impulsive moves.
Have a ball! But always stay in control
and y in a safe manner.
GOOD LUCK AND GREAT FLYING!
