Get your model ready to fly
Important ESC and model information
The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the
throttle stick is not in the low throttle or off position, the motor will not start until the throttle stick is moved to
the low throttle or off position. Once the throttle stick is moved to the low throttle or off position, the motor will
emit a series of beeps. Several beeps with the same tune means the ESC has detected the cells of the
battery. The count of the beeps equals the cells of the battery. The motor is now armed and will start when
the throttle is moved.
The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the
motor is rotating in the wrong direction, simply reverse two of the three motor wires to change the direction
of rotation.
The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that
the model be flown with the brake off. However, the brake could be accidentally switched on if the motor
battery is connected to the ESC while the throttle stick is set at full throttle. To switch the brake off, move the
throttle stick to full throttle and plug in the motor battery. The motor will beep one time. Move the throttle stick
to low throttle or the off position. The motor is ready to run and the brake will be switched off.
Battery Selection and Installation. We recommend the 22.2V 2600-3300Ah 35c Li-Po battery for inner
running motor power and 14.8V 2600-3300Ah 35c Li-Po battery for outer running motor power. Your battery
should be approximately the same capacity, dimension and weight as the recommended battery to fit the
fuselage without changing the center of gravity significantly.
The transmitter and model setup
Before getting started, bind your receiver with your transmitter. Please refer to your Transmitter Manual for
proper operation
CAUTION: To prevent personal injury, DO NOT install the propeller assembly onto the motor shaft while
testing the control surfaces. DO NOT arm the ESC and do not turn on the transmitter until the Transmitter
Manual instructs you to do so.
Tips: Make sure all control sticks on your radio are in the neutral position (rudder, elevator, ailerons) and the
throttle is in the OFF position. Make sure both ailerons move up and down (travel) the same amount. This
model tracks well when the left and right ailerons travel the same amount in response to the control stick.
1. Move the controls on the transmitter to make sure the aircraft control surface moves correctly. See
diagrams below.

Check the control throws
The suggested control throw setting for FMS MODEL are as follows (dual rate setting):
Tips: On first flight, fly the model in low rate. The first time you use high rates, be sure to fly at low to medium
speeds. High rate, as listed, is only for EXTREME maneuvering.

Check the C.G. (Center of Gravity)
When balancing your model, adjust the motor battery as necessary so the model is level or slightly nose down.
This is the correct balance point for your model. After the first flights, the CG position can be adjusted for your
personal preference.
1. The recommended Center of Gravity (CG) location for your model is (100-105mm) forward from the leading
edge of the main wing (as shown) with the battery pack installed. Mark the location of the CG on top of the
wing.
2. When balancing your model, support the plane at the marks made on the bottom of the main wing with your
fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure
the model is assembled and ready for flight before balancing.

Before flying the model
Find a suitable flying site
Perform the range check for your plane
Monitor your flight time
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.
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 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
Flying
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).
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.
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.
Recharge the battery and repair the model as needed .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 lightly on the mains and you can hold the nose
wheel off balancing the model on the mains until it slows and gently settles the nose.
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.
