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 fl ying sites and AMA-
sanctioned fl ying events. Fill out the identifi 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 fl 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 initial charge is done with a fast-charger the batteries
may not reach their full capacity and you may be fl 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 ground-
check the operational range of your radio before the fi rst
fl 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 fl y!
Find and correct the problem fi 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.
PREFLIGHT
FLYING
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 fl avor. It is a
great little sport plane
that fl ies well on the 3s
and 4s packs that are
very common in the hobby. It has been fl own on batteries
from 1800 to 3200 mAh. We like the balance of weight and
duration with 2200 mAh batteries. The CG range is very
wide and it will fl 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
fl ying airplane. The profi le canopy/turtle deck is not only
for appearance, but also functionality. High alpha 3D fl 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 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. If fl utter is detected, slow the model
immediately
and land as soon as safely 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 fl 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 fl y
for 6 to 8 minutes or more on a 4S 2200 mAh LiPo battery.
Set the timer for 5 minutes for the fi rst few fl ights. When
