Features of F121 Pro

As the mini racing drone that can fly at high speed at Altitude Hold Mode, F121 Pro is very easy to master for drone freshman. The inertial navigation system technology blending Kalman filtering, gyro, accelerometer, andbarometer makes F121 Pro possible to flight through narrow space with accuracy and hold altitude evenit’slessthan ten centimeters height to the surface or at high speed. F121 Pro have three flight modes that AltHold Mode, Stabilize Mode and Manual Mode. Even beginners can flight stably at the first trial at AltHold Mode. F121 Pro is monitored by RadioLink mini racing drone flight controller F121, which is different fromother flight controllers with PID needs to be set before use, will tune automatically. Thesoftware noise reductiontechnologynot only enables a more pleasant flight but also makes the motors more responsive and more efficient than traditional 8520 brush-less motors. It can be thrown and start to fly at any angle even under high-speedandremains stable even facing with sudden airflow fluctuations such as during takeoff, under braking, or after extended flying. Without compass locking, F121 Pro always automatically modify angles during flight.

Before Flight

Power Supply

Power for transmitter T8S: Make sure the transmitter is fully charged.
Power for F121: The voltage of 1S LiPo battery packed with F121 Pro by default is not fully chargedsothebattery needs to be charged with the charger CM120 before flight.
The LiPo battery charger CM120, specially designed for 1S LiPo battery, sharing the professional developmentand high precision of CB86PLUS, ensures safer charging and battery life span.

Charging current can be set as 1A or 2A by toggling the switch at the side of the charger.
The Red LED always on indicates the battery is under charging. The Green LED always on indicates thebatteryis fully charged.
The Red and Green LED Flashing alternately indicates fault prompt.
CM120 applies general USB connector, both computer and power bank for mobile phone can beusedwithCM120.
Note: Voltage output of power supply should be NO higher than 5V.

Transmitter

The two joysticks of T8S correspond to the four basic channels respectively. The below example takes RadioLinkradio T8S Mode 2 (Throttle on the left stick).

Left joystick
Make the F121 Pro rise or descend by toggling the left stick (THROTTLE) vertically upward or downward and turn clockwise or anticlockwise by toggling the left stick (YAW) to the left or right.

Right joystick
Make the F121 Pro fly forward or backward by toggling the right stick (PITCH) vertically upward or downward and to left or right by toggling the right stick (ROLL) to the left or right.

Note If it’s the transmitter from other brands used with RadioLink F121 Pro, make sure that the receiver shouldbe SBUS signal output supported. Once the receiver is installed on the mini drone, the phase of thethrottleshould be reversed while the other three channels normal and the CH5 should be set with a 3-wayswitchtochange the flight mode and the CH7 set a switch (a 2 way switch or a 3-way switch is OK) for armor disarm.Servo phases of transmitters from other brands should be set according to the actual  situation.

B. Yaw: Clockwise/Anticlockwise
Toggle the yaw stick (on the left) to the left and F121 Pro will turn anticlockwise and toggle the yawstick to the right, then F121 Pro turns clockwise.

C. Pitch: Forward/Backward
Toggle the pitch stick (on the right) vertically upward and F121 Pro will fly forward and toggle the pitch stick vertically downward, then F121 Pro flies backwards.

D. Roll: Right/Left
Toggle the roll stick (on the right) to the left and F121 Pro will fly to the left side and toggle the roll stick totheright,then F121 Pro will fly to the right side.

Get Ready to Flight

Motor Installation

To make the aircraft fly, motors usually rotate clockwise (CW)/ counter clockwise (CCW) with the propellers. The rotation direction of F121 Pro motors can be identified by the cable colors. That is, motor with red and blue wire means motor of clockwise (CW) while with black and white wire means that of counter clockwise (CCW). It isveryimportant to make sure about the rotation direction as below when installing motors. Otherwise, the drone would fail to take off.

• Motors installation can be skipped as the whole F121 Pro is already assembled by factory default. If anyof themotors is worn out and needs to be replaced, it’s essential to identify the correct motor rotation.

Propellers and Propeller Protectors Installation

F121 Pro is installed propellers protector by factory default, you can follow the steps below if you need change them. To ensure a safety flight, it’s strongly advised to check if the protectors are well installed.

1. Find the two notches respectively on the motor protector and propeller protector as image on the right.
   

2. Put on the propeller protector from the bottom and adjust the position of the notches correspondingly.

3. Stabilize the frame with left hand and buckle the notch of one side with right hand. Then buckle the notch of the other side with left hand. A “DA” sound will be heard if the installation is done with success.

4. Extra 4 screws are in the package and pilot can installed on the propeller protector as prefer.
   

Note After the installation of the four propeller protectors, double confirm if they are leaning or slightly shakeF121 Pro to see if they drop. If they are crooked or drop, repeat the above steps to ensure the well installation.
Propeller installation can be skipped as the whole F121 Pro is already assembled by factory default. If thedefault propellers get worn and needs to be replaced after a period of flight, it is important to well identifytherotation direction of propellers. If installed incorrectly, F121 Pro can’t take off even the throttle is pushedtomax.
In order to identify the propellers rotation, take a propeller and observe there’s a radian at both sidesof thesmall cylinder in the middle. The higher part (also called windward side) of the right propeller is at thefront andthe rotating motor will make propeller rotate counterclockwise (CCW). On the contrary, that is clockwise(CW)rotation. For the 65mm GEMFAN propellers used on F121 Pro, there are two marked with a letter R, meaningthey should be installed on the motors of clockwise.

When the installation is done, make sure the four motors are vertical to the aircraft frame. If necessary, adjustthem to vertical positions, otherwise F121 Pro may not flight successfully.

Power on F121 Pro

Before powering on F121 Pro, make sure T8S is fully charged. Put the throttle stick at the lowest positionandlong press power key to power on T8S. Then power on F121 Pro. Fully charge the 1S LiPo battery first. PlugthePH2.0 end of the battery into the F121 Pro, then insert the battery into the battery frame under at thebottomofF121 Pro.

1. Orange propellers indicates the head of F121 Pro by default. make sure they point to the samedirectionasthe pilot when powering on and be ready to fly, to ensure safety.
2. The green LED of F121 Pro will begin flashing when powered on. When it’s off, it means F121 Profinishescalibration.

Note Head direction is determinate. If F121 Pro is calibrated with the direction different fromthe  default, it will turn back to the default direction automatically when starts flying, that’s what we called Head Front ForwardPointWithout Compass.

Flight Note

If it’s the first time of flying drone, flight mode of Altitude Mode is strongly advised to set. At the AltitudeMode,when toggle the throttle upward till the drone reaches a certain height and release, F121 Pro will remainat thisheight. It’s simpler because pilots only need to toggle the other joystick to make the F121Promoveforward/backward or turn left/right. If it’s the Stabilize Mode especially Manual Mode chosen, try totogglethejoysticks slightly to correct the flight and avoid the drone having sudden moves.
If F121 Pro drops by hitting something, toggle the throttle joystick to the bottom position immediatelytostopmotor rotation. Make sure the signal output of receiver is SBUS to ensure normal operation of F121 Pro. For RadioLink receivers(R8SM/R6DSM) installed on F121 Pro, the LED indicator is blue/purple when it’s SBUSworkingmode.

Setup Compatible Transmitters

By factory default, RTF version of F121 Pro is packed with the transmitter T8S and receiver R8SMcombo. Receiver R8SM is also compatible with RadioLink T8FB.
If you ready to change the transmitter to AT10/AT10II/AT9/AT9S/AT9S Pro to control the F121 Pro, compatible receiver should be R6DSM.
If it’s transmitters of other brands used, compatible receiver chosen should capable of supporting SBUSoutput.

T8FB/T8S
RadioLink 8-channel transmitter are well set by factory default with the flight modes. To control F121Pro, bindingis the only thing needs to be done. There are three flight modes for F121 Pro including Altitude Mode, Stabilize Mode and Manual Mode. It canbechanged by pressing the three-way switch on the right of T8FB- SWB or of T8S- CH5 as below.

AT9S Pro/AT9S/AT9/AT10/AT10II

1. Enter BASIC MENU, select MODEL TYPE and choose MULTIROTOR.
2. Back to BASIC MENU, select REVERSE and set CH3 Throttle as REV.
3. Back to BASIC MENU, select AUX-CH and set CH7 control switch as SwA.
4. Enter ADVANCE MENU, select ATTITUDE and set the CHANNEL as CH5, SW3 as SWC with uppositionasAltHold Mode, middle position as Stabilize Mode and low position as Manual Mode.
   
   

• For more setting instructions of different RadioLink transmitters, please visit www.radiolink.com to download the corresponding detailed e-manual.

Binding

There’s no need to bind because the binding is complete with receiver R8SM installed by factory default if theRTF version (whole pack including T8S+F121+bag) you have purchased. However, if you want to change the control transmitter, binding between the transmitter and receiver needstodone first.

If fly F121 Pro with RadioLink transmitter and receiver, binding steps are same as following.

1. Place the transmitter and receiver(installed on F121 Pro) close to each other within 50 centimeters.
2. Power on the transmitter and the receiver.
3. There is a black binding button(ID SET) on the side of the receiver, press it for more than 1 second. WhentheLED starts flashing, meaning binding process has started.
4. The binding is complete when the LED is always on.
5. Make sure F121 Pro is armed (Details in next section). Gently push the throttle of transmitter to seeif motorsmove. If doesn’t, retry binding again.
   

Note

• F121 Pro currently supports SBUS signal output only, always make sure the LED of R8SM/R6DS Misblue/purple, meaning SBUS signals output. If the LED is red, press the binding button twice in 1second and release to change it to purple/blue.
• If it’s the transmitter of AT9S Pro/AT9S/AT10/AT10II used, channel quantity needs to be set first inorder tobe compatible with receiver R6DSM. Long press MODE to enter BASICE MENU, select SYSTEMandmodify CH-SELECT as 10CH. Otherwise, F121 Pro won’t be able to be armed.

Flight at Different Flight Modes

It’s strongly advised for beginners to start from Altitude Hold Mode to then to Stabilize Mode.
It’s better to keep the direction of F121 Pro head same as pilot in order to easily judge the flight direction.Otherwise, F121 Pro may flight towards pilot and get him/her hurt. If the aircraft head is changed unexpectedlyand different from pilot’s direction, pull the throttle stick to the lowest position to land F121 Pro. Experienced pilots can control the F121 Pro with the Manual Mode to enjoy the funny freestyle and racingtime.

Arm and Disarm F121 Pro

How to arm

Press the CH7 switch (the 3-way switch on the left of T8S) towards the back of T8S, the green LEDof F121Prois on means arm successful. When the transmitter is T8FB, put the CH7 switch (the 2-way switch ontheleft)tothe top position to arm. If you use the other transmitter except the T8S or T8FB to control the F121Pro, set a2-way switch to control the CH7, and when the switch at the top position, the green LED of F121 Proisonmeansarm successful. For security reasons, F121 Pro will be disarmed automatically if there is not any operationof thethrottle for 5 seconds. So arm F121 Pro again when the flight is ready.

How to disarm

When the flight is finished, always make sure F121 Pro is disarmed when get close and try touching it to avoid unexpected harm. Always be sure about turning off F121 Pro before T8S. Press the CH7 switch (the 3-way switch on the left of T8S) towards the front of T8S, the green LEDof F121Prois off means disarm successful. When the transmitter is T8FB, put the CH7 switch (the 2-way switch on the left)to the bottom position to disarm. If you use the other transmitter except the T8S or T8FB to control theF121Pro,set a 2-way switch to control the CH7, and when the switch at the bottom position, the green LEDof F121Proisoff means disarm successful.

Altitude Hold Mode

Rise/Descend

Press the CH5 switch of T8S backward, which makes F121 Pro fly at Altitude Hold Mode. Make suretheorangepropellers at front when powering F121 Pro on. Then arm F121 Pro and push the throttle joystick vertically upward higher than center position, then the F121 Pro will rise while if push it vertically downward, thentheF121Pro will descend.

Hover

Push the throttle joystick vertically upward till the F121 Pro rises to a height as wish, then toggle it back to center position and release, the F121 will hover at this height.

Forward/Backward/Right/Left

At Altitude Mode, F121 Pro can fly forward/backwards or towards to right/left by toggling the right stickat thecertain height. For beginners, make sure to push the stick gently because being a racing drone, F121 Pro is very responsive. It’sadvised to release the stick as soon as toggle to one direction so that F121 Pro will back to level automatically.Otherwise, F121 Pro will keep flying to the toggled direction with accelerated speed.

Clockwise/Anticlockwise Rotation

When get familiar with the above flights, try flight clockwise/anticlockwise because the yaw practice is more difficult to judge the flight direction. Clearly knowing the direction will quickly help master drone flight. Tryimaginesitting on the drone could be a better way to practice. Toggle the rudder joystick to the left and F121 Pro will flight anticlockwise while if to the right, then the F121 Pro will flight clockwise.

Stabilize Mode

Press the CH5 switch of T8S to the center position to change the F121 Pro working mode to StabilizeMode. The basic operation such as Rise/Descend/Forward/Backward etc. of Stabilize Mode are same as Altitude Hold Mode.
When at Stabilize Mode, F121 Pro will flight faster than when at Altitude Mode.
The flight controller will not help keep F121 Pro altitude hold, which is more challenging, that will askthepolitkeep a long-time practice.
The flight angle of F121 Pro still limited at Stabilize Mode, if you want to control the F121 Pro keeproll overorfreestyle, the Manual Mode will be the best choice.

Manual Mode

Manual Mode is the classic FPV flight control mode.
Press the CH5 switch of T8S backward to change the F121 Pro working mode to Manual Mode. Thebasicoperation such as Rise/Descend/Forward/Backward etc. of Manual Mode are same as Altitude HoldMode. When at Manual Mode, the flight controller will stop to working, F121 Pro will flight faster than when at Altitude Mode or Stabilize Mode and there is no limited to the flight angle, you can control the F121 Pro keeproll overorfreestyle.
Please make sure that you have skillful to control the F121 Pro and then select the Manual Mode. Toggle joysticks as gentle as possible to avoid drastic movements, which may possibly hurt the pilot. Make surethat thebattery is fully charged before enjoying the flight.

Switch for 360 Angle Flips Mode

F121 Pro add a mode named Switch for 360 Angle Flips Mode except Altitude Hold Mode, StabilizeModeandManual Mode, the setting steps as below:

When the transmitter is T8S, press the CH6 switch twice continuous and then push the aileron or elevator stick. If push the aileron stick to the left, the F121 Pro will roll 360 degrees to left. If push the aileron stick to theright, theF121 Pro will roll 360 degrees to right. If push the elevator stick upward, the F121 Pro will roll 360degrees forward.
If push the elevator stick downward, the F121 Pro will roll 360 degrees backward. When you ready to controlling your F121 Pro roll 360 degrees backward, you must fly your F121 Profar awayfrom yourself first to ensure safety.

When the transmitter is T8FB, the 360 Angle Flips Mode switch is VrB, the operating steps are sameasT8S.

Attention:

1. the interval time for push the aileron or elevator stick do not more than 5 second whenyoupressthe 360 Angle Flips Mode Switch. You have pressed the switch again if the time is more than 5 second.
2. the 360 Angle Flips Mode only adapted to the Altitude Hold Mode and the Stabilize Mode. 360 degreesroll atManual Mode depends on the pilot’ operating of sticks.

Low Battery Alarm

When the green LED on F121 Pro starts slowly flashing during flight, it means the voltage of F121Proislowerthan 3.7V, when the green LED on F121 Pro starts quickly flashing during flight, it means the voltage of F121Pro is lower than 3.8V as this value is default for 1S battery. It’s advised to stop flying to avoid battery over discharging.

• F121 Pro FPV RTF version is capable of OSD function and pilot can check the current voltage of the battery by goggle or FPV screen in real time.

Calibration

Level calibration have finished when you received the F121 Pro, you can re- calibrate if you need. F121 Pro is in disarmed state when calibration.

Level calibration steps as below:

1. make sure the four motors are vertical to the aircraft frame. If necessary, adjust them to vertical positions, otherwise F121 Pro may not flight that balance.
2. put the F121 Pro on a level surface, and then power on both F121 Pro and transmitter.
3. put the left stick to the lower left position and the right stick to the lower right position, keep about 3 seconds till the green LED of F121 Pro blink once, then calibrate success.
