or lift at the lines you marked indicating the recommended,
starting C.G. Depending on the battery you are using, there
should be a little leeway to shift the battery forward or aft
to change the C.G. so it balances at the recommended
starting C.G.
❏
4. Once the location of the battery has been determined,
make a mental note of this location, or mark the inside of the
fuselage or the battery tray to position the battery here for
the proper C.G. when fl ying the model.
Balance the Model Laterally
❏
1. Leaving the tail skid on the work surface, lift the Tori
several times by the propeller shaft 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.
PREFLIGHT
Motor Safety Precautions
Failure to follow these safety precautions may result
in severe injury to yourself and others.
● Use safety glasses when starting or running motors.
● Do not run the motor 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 run the motor.
● 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.
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), always turn on the transmitter
fi rst before connecting the motor battery.
Also make certain your Fail Safe is programmed
correctly so in the event the receiver ever loses signal
(or, if you inadvertently turn off the transmitter before
disconnecting the battery or vice-versa) the motor will
not turn. Follow the instructions that came with your radio
control system to check and set the Fail Safe.
CAUTION: Never run the motor on the ground for more
than a few seconds. Otherwise, you may overload the
motor, battery or ESC.
Range Check
Don't forget to perform your usual ground range checks as
written in the instruction manual that came with your radio
system to be certain it is operating correctly.
General Prefl ight Information
The RimFire .10 is rated for 30A constant current and 35A
surge current. The included 12x6.5 folding propeller draws
an average maximum (in fl ight) current of about 29A on a
3S battery and about 23A on a 2S battery, so there is no
danger of overloading the motor and it can be run full-
throttle for extended periods (during massive ascensions
to altitude). With a 3S 1800mAh battery this should provide
approximately three minutes of full-throttle run time and with
a 2S 2200mAh battery about 4-1/2 minutes of full-throttle run
time. On 3S the Tori "specs out" in about twenty seconds.
You may experiment with 2S and 3S batteries to fi nd the
combination you like best. With lighter 2S batteries the Tori
may not climb as quickly, but it will be lighter and have a
farther aft C.G. for detecting thermals easier.
Either way, it is recommended to use a fl ight timer to indicate
when to stop running the motor so as not to over-discharge
the battery. In the case of a glider such as the Tori, it is
desirable to link the timer to the throttle stick so only motor
run time—not the total time the model is airborne—will be
counted. Until you know what time to set the timer for, start
with a conservative number: say two-minutes for a 3S setup
and three-minutes for a 2S setup.
