Before Flying The Model; Flying Course - FMS 850mm Ranger Manuel D'utilisation

Before flying the model

Find a suitable flying site
Find a flying site clear of buildings, trees, power lines and
other obstructions. Until you know how much area will be
required and have mastered flying your plane in confined
spaces, choose a site which is at least the size of two to three
football fields - a flying field specifically for R/C planes is best.
Never fly near people - especially children, who can wander
unpredictably.
Perform the range check for your plane
As a precaution, an operational ground range test should be
performed before the first flight each time you go out.
Performing a range test is a good way to detect problems
that could cause loss of control such as low batteries, defective
or damaged radio components, or radio interference. This
usually requires an assistant and should be done at the actual
flying site you will be using.
First turn on the transmitter, then install a fully-charged battery
into the fuselage. Connect the battery and install the hatch.
Remember, use care not to bump the throttle stick. Otherwise,
the propeller/fan will turn and possibly cause damage or injury.
Note: Please refer to your Transmitter Manual that came with
your radio control system to perform a ground range check. If
the controls are not working correctly or if anything seems
wrong, do not fly the model until you correct the problem. Make
certain all the servo wires are securely connected to the
receiver and the transmitter batteries have a good connection.
Monitor your flight time
Monitor and limit your flight time using a timer (such as on a
wristwatch or in your transmitter if available). When the
batteries are getting low you will usually notice a performance
drop before the ESC cuts off motor power, so when the plane
starts flying slower you should land. Often (but not always)
power can be briefly restored after the motor cuts off by
holding the throttle stick all the way down for a few seconds.
To avoid an unexpected dead-stick landing on your first flight,
set your timer to a conservative 4 minutes. When your alarm
sounds you should land right away.

Flying course

Take off
While applying power, slowly steer to keep the model straight.
The model should accelerate quickly. As the model gains flight
speed you will want to climb at a steady and even rate. It will
climb out at a nice angle of attack (AOA).
Flying
Always choose a wide-open space for flying your plane. It is
ideal for you to fly at a sanctioned flying field. If you are not
flying at an approved site always avoid flying near houses,
trees, wires and buildings. You should also be careful to avoid
flying in areas where there are many people, such as busy
parks, schoolyards, or soccer fields. Consult laws and
ordinances before choosing a location to fly your aircraft. After
takeoff, gain some altitude. Climb to a safe height before trying
technical manoeuvres, including high speed passes, inverted
flight, loops, and point rolls.
Landing
Land the model when you hear the motor pulsing (LVC) or if
you notice a reduction in power. If using a transmitter with a
timer, set the timer so you have enough flight time to make
several landing approaches.
The model's three point landing gear allows the model to land
on hard surfaces. Align model directly into the wind and fly
down to the ground. Fly the airplane down to the ground using
1/4-1/3 throttle to keep enough energy for proper flare. Before
the model touches down, always fully decrease the throttle to
avoid damaging the propeller or other components. The key to
a great landing is to manage the power and elevator all the
way to the ground and set down lightly on the main landing
gear. After a few flights you will find the model can be set down
lightlyon the mains and you can hold the nose wheel off
balancing themodel on the mains until it slows and gently
settles the nose.
Maintenance
Repairs to the foam should be made with foam safe adhesives
such as hot glue, foam safe CA, and 5min epoxy. When parts
are not repairable, see the Spare Parts List for ordering by item
number.
Always check to make sure all screws on the aircraft are
tightened. Pay special attention to make sure the spinner is
firmly in place before every flight.
