Charging the Flight Battery
The Battery Charger included with your aircraft is designed to safely charge the Li-Po battery,
Caution: All instructions and warnings must be followed exactly. Mishandling of Li-Po
batteries can result in fire, personal injury, or property damage.
Battery warning:
By handling, charging or using the included Li-Po battery
you assume all risks associated with lithium batteries.
If at any time the batteries begin to swell, or balloon, discontinue use immediately!
Charging or discharging a swelling or ballooning battery can result in fire.
Always store the batteries at room temperature in a dry area to extend the life of
the battery. Always transport or temporarily store the battery in a temperature range of
40-120 oF. Do not store battery or model in a car or in direct sunlight. If stored in a hot car,
the battery can be damaged or even catch fire.
Never use a Ni-Mh charger. Failure to charge the battery with a compatible charger may
cause fire resulting in personal injury and property damage.
Never discharge Li-Po cells to below 3V.
Never leave charging batteries unattended.
Never charge damaged batteries.
Charging the flight battery
RTF kits come with a DC balancing charger. You must charge the battery with
a Li-Po specific charger only (such as the included BC-3S10 DC charger). When charging
the battery, make certain the battery is on a heat-resistent surface, charge the battery
before assembly of the airplane. Install the fully charged battery to perform control tests
and binding.
BC-3S10 Balance Charger
To correctly use the charger, please read the instructions before use.

Using Steps:
1. Connect the charger to adapter with enough voltage and wattage, then the Power LED will turn on;
2. Connect 2S/3S battery pack to the corresponding balance port (Do not connect two battery
packs at the same time), then the Charge LED will flicker (1Hz) and start charging.
3. When the Charge LED stops flickering, charging is complete, and the batteries can be unplugged.
Charging Function Description
1. If all voltage of the installed battery pack is higher than 4.18V, charging will not start and the charge
LED will shine.
2. If the voltage of one battery or some batteries is lower than 0.7V, charging will not start. If the
voltage of the first battery of a 3S battery pack is lower than 0.7V, the charger will charge the battery
pack as if it was a 2S battery pack.
3. If the voltage of one battery or some batteries is lower than 2.8V, the charger will activate the battery
pack with a small current. If the voltage can’t be increased above 2.8V after half an hour, the charger
will judge the battery pack as bad. The charge LED will then flicker rapidly (0.5Hz), and charging
will stop.
Self Checking Function
1. Charger will perform a self test before each charge. The charge LED will rapidly flicker
(0.5Hz) if the charging function is abnormal;
2. Accuracy checking Function: Connect a fully charged 3S battery pack (all voltage at least 4.2V),
the charge LED will flicker twice then shine always. This means that the accuracy is normal.

Troubleshooting
1. Power LED does not shine – Adapter isn’t connected correctly. Please check the polarity and
reconnect adapter.
2. Charging abruptly stops and tries to restart constantly during charging – Output power of
the adapter is not sufficient, please replace the adapter.
3. Charge LED does not shine – Reconnect the battery pack; Check the voltage of batteries.
4. Charge LED rapidly flickers – Battery is bad or charging function is abnormal. Replace battery
or contact technical support.

Low voltage cut off (LVC)
WhenaLi-Poisdischarged below 3V per cell, it will not hold a charge. The ESC protects
the flight battery from over-discharge using Low Voltage Cutoff. Before the battery charge
decreases too much, LVC removes power from motor in two ways: (1) Reduces power ESC reduces motor power (recommended), (2) Hard cutoff - ESC instantly cuts motor
power when the pre-set Low Voltage Protection Threshold value is reached. These
settings can be changed using the ESC programing guide (available on-line).

Important ESC and model information
1. The ESC included with the Beechcraft 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 detect the cells of the battery.
The count of the beeps equal the cells of the battery. The motor is now armed and will
start when the throttle is moved.
2. 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.
3. The motor has an optional brake setting. The ESC comes with the brake switched off
and we recommended that the sky trainer 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.
4. Battery Selection and Installation. We recommend the 11.1V 1800mAh 25C Li-Po
battery. If using another battery, the battery must be at least a 11.1V 1800mAh 25C
battery. Your battery should be approximately the same capacity, dimension and
weight as the 11.1V1800mAh 25C Li-Po battery to fit in 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 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 aircraft control surface move
correctly. See diagrams below.

2. Make sure all servo arms are fully vertical. If not, adjust the servo arm by using the trim
function on your radio. Note: For computerized transmitters, use the servo/channel
sub-trim feature to make each servo arm fully vertical.
3. The standard hole settings for linkage connections are shown by the black arrows in the
the diagram below. You can move the linkage to different hole positions to increase
control surface travel and increase the aerobatics of the airplane.
4. Align aileron and flap with the wing root by turning the clevis clockwise and
counterclockwise on the linkage, carefully open the clevis fork and put the clevis pin in
the desired hole of the control horn.
Note: Please secure the clevis with provided piece of tube after the alignment of the
surface is completed.

Check the C.G. (Center of Gravity)
Center of Gravity
When balancing your model, adjust the motor battery as necessary so the model is level or
slightly nose down. This 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 ( 60mm/2.4in ) 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.
3. Always balance the aircraft with the retracts down.
page19
For More Info Vist: www.motionrc.com
Before the model flying
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.
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 one on a wrist watch 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.
The Beechcraft 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 altitude and begin to trim the model till it’s tracks well through all
aspects of flight, 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.
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 till 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 5 min 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 grabbed in place before every flight.

Academy of Model Aeronautics National Model Aircraft Safety Code
Effective January 1, 2011
A. GENERAL: A model aircraft is a non-human-carrying aircraft capable of sustained
flight in the atmosphere. It may not exceed limitations of this code and is intended
exclusively for sport, recreation and/or competition.
All model flights must be conducted in accordance with this safety code and any
additional rules specific to the flying site.
1. Model aircraft will not be flown:
(a) In a careless or reckless manner.
(b) At a location where model aircraft activities are prohibited.
2. Model aircraft pilots will:
(a) Yield the right of way to all man carrying aircraft.
(b) See and avoid all aircraft and a spotter must be used when appropriate.
(AMA Document #540-D-See and Avoid Guidance.)
(c) Not fly higher than approximately 400 feet above ground level within three (3) miles
of an airport, without notifying the airport operator.
(d) Not interfere with operations and traffic patterns at any airport, heliport or seaplane
base except where there is a mixed use agreement.
(e) Ensure the aircraft is identified with the name and address or AMA number of
the owner on the inside or affixed to the outside of the model aircraft.
(This does not apply to model aircraft flown indoors).
( f ) Not operate aircraft with metal-blade propellers or with gaseous boosts except for
helicopters operated under the provisions of AMA Document #555.
(g ) Not operate model aircraft while under the influence of alcohol or while using any
drug which could adversely affect the pilot’s ability to safely control the model.
(h ) Not operate model aircraft carrying pyrotechnic devices which explode or burn,
or any device which propels a projectile or drops any object that creates a hazard
to persons or property.

Exceptions:
◆ Free Flight fuses or devices that burn producing smoke and are securely attached to
the model aircraft during flight.
◆ Officially designated AMA Air Show Teams (AST) are authorized to use devices and
practices as defined within the Team AMA Program Document (AMA Document #718).
3. Model aircraft will not be flown in AMA sanctioned events, air shows or model
demonstrations unless:
(a) The aircraft, control system and pilot skills have successfully demonstrated all
maneuvers intended or anticipated prior to the specific event.
(b) An inexperienced pilot is assisted by an experienced pilot.
4. When and where required by rule, helmets must be properly worn and fastened.
They must be OSHA, DOT, ANSI, SNELL or NOCSAE approved or comply with
comparable standards.
B. RADIO CONTROL (RC)
1. All pilots shall avoid flying directly over unprotected people, vessels, vehicles or
structures and shall avoid endangerment of life and property of others.
2. A successful radio equipment ground-range check in accordance with manufacturer’s
recommendations will be completed before the first flight of a new or repaired model
aircraft.
3. RC model aircraft must use the radio-control frequencies currently allowed by the
Federal Communications Commission (FCC). Only individuals properly licensed by
the FCC are authorized to operate equipment on Amateur Band frequencies.
4. RC model aircraft will not operate within three (3) miles of any pre-existing flying site
without a frequency-management agreement (AMA Documents #922-Testing for RF
Interference; #923- Frequency Management Agreement)
5. With the exception of events flown under official AMA Competition Regulations,
excluding takeoff and landing, no powered model may be flown outdoors closer than
25 feet to any individual, except for the pilot and the pilot's helper(s) located at the
flight line.
6. Under no circumstances may a pilot or other person touch a model aircraft in flight
while it is still under power, except to divert it from striking an individual.
This does not apply to model aircraft flown indoors.
7. RC night flying requires a lighting system providing the pilot with a clear view of the
model’s attitude and orientation at all times.
8. The pilot of a RC model aircraft shall:
(a) Maintain control during the entire flight, maintaining visual contact without
enhancement other than by corrective lenses prescribed for the pilot.
(b) Fly using the assistance of a camera or First-Person View (FPV) only in accordance
with the procedures outlined in AMA Document #550.
C. FREE FLIGHT
1. Must be at least 100 feet downwind of spectators and automobile parking when the
model aircraft is launched.
2. Launch area must be clear of all individuals except mechanics, officials, and other fliers.
3. An effective device will be used to extinguish any fuse on the model aircraft after the
fuse has completed its function.
