Balance The Model Laterally; Preflight; Engine/Motor Safety Precautions - Tower Hobbies Uproar V2 .46 EP ARF Instruction Manual

engines that have a 1/4" prop shaft and the second "step"
on the reamer is good for the RimFire .32 with a 5/16" prop
shaft. The spinner cone may be trimmed carefully with a
hobby knife with a #11 blade. Glow engine setups should
be balanced with an empty fuel tank.
[ 83 mm]
The recommended C.G. is 3-1/4" [ 83 mm] back from
the leading edge of the wing. The recommended C.G.
range is from 2- 3/4" to 3-3/4" [ 70 mm to 95 mm].
2. Use a Great Planes C.G. Machine with the rulers set to
the recommended C.G. and place the model upside-down
on the stand, or mark the recommended C.G. on top of the
wing and lift the model upside-down with your fi ngertips.
3. Add nose or tail ballast as necessary to get the model
to balance.

Balance the Model Laterally

1. Lift the Uproar V2 several times by the propeller shaft
and the tail to see if one wing drops.
2. If one wing drops consistently, add weight to the
opposite tip by sticking it to the outside or strategically
concealing it inside the balsa tip. An airplane that has
been laterally balanced will track better in fl ight and
maintain its heading better during maneuvers when the
plane is climbing.
Failure to follow these safety precautions may result
in severe injury to yourself and others.
3-1/4"
WARNING: For brushless electric motors, never have the
motor battery connected to the ESC without the transmitter
turned on – after each fl ight (or any time after running
the motor) always disconnect the battery before turning
off the transmitter. And when ready to fl y (or whenever
running the motor for any reason), lower the throttle stick
and always turn on the transmitter fi rst before connecting
the motor battery.
Also make certain your failsafe is activated and programmed
correctly according to your radio manufacturer's instructions.
The recommended RimFire .32 is rated for 50A constant
current and 80A surge current. Powered by a 4S LiPo on
an APC 13 x 8E it draws about 58A static and momentary,
maximum peaks of about 50 – 55A in the air, but averages

PREFLIGHT

Engine/Motor Safety Precautions

Keep all engine fuel in a safe place, away from high heat,
sparks or fl ames, as fuel is very fl ammable. Do not smoke
near the engine or fuel; and remember that engine exhaust
gives off a great deal of deadly carbon monoxide. Therefore
do not run the engine in a closed room or garage.
Get help from an experienced pilot when learning to
operate engines.
Use safety glasses when starting or running engines.
Do not run the engine in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
Keep your face and body as well as all spectators away
from the plane of rotation of the propeller as you start and
run the engine.
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.
Use a "chicken stick" or electric starter to start the engine.
Do not use your fi ngers to fl ip the propeller. Make certain
the glow plug clip or connector is secure so that it will not
pop off or otherwise get into the running propeller.
Make all engine adjustments from behind the rotating
propeller.
The engine gets hot! Do not touch it during or right after
operation. Make sure fuel lines are in good condition so
fuel will not leak onto a hot engine, causing a fi re.
To stop a glow engine, cut off the fuel supply by closing
off the fuel line or following the engine manufacturer's
recommendations. Do not use hands, fi ngers or any other
body part to try to stop the engine. To stop a gasoline
powered engine an on/off switch should be connected to
the engine coil. Do not throw anything into the propeller
of a running engine.
