Charging the Flight Battery
For More Info Vist: www.motionrc.com

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.
Protection Function
1. Reverse connection protection of input
2. Reverse connection protection of output
3. Short circuit protection of output
4. Over voltage protection of output
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.

WhenaLi-Poisdischarged 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).

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 ( ) forward from170-172mm
the trailing 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 inverted at the marks made on the top 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.

Important ESC information
1. The ESC included with the F-16 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 F-16 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 Move the throttle one time.

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 11.1V 1800mAh 25C Li-Po battery to fit in the fuselage without changing
the center of gravity significantly.

Get your model ready to fly
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.

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 the control surface 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 control throws
The suggested control throw settings for ROC HOBBY are as follows (Dual rate setting):
High Rate Low Rate
Elevator 15mm up/down 10mm up/down
Aileron 17mm up/down 11mm up/down
Front landing gear steering: left/right 30 degree
Tips: At 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 rates, as listed, are only for EXTREME maneuvering.
