FPV Drone Cetus Pro. for a Quick Entry Into the Hobby

Introduction

The BetaFPV Cetus Pro FPV Kit is an updated FPV kit for beginners, proposed by the developer to replace the previous BetaFPV Advanced Kit 2. The novelty includes a new FPV quad model built on a solid monolithic frame with an annular protection of the power plant, which traditionally consists of four brushless motors. The drone now supports three flight modes (Normal/Sport/Manual), among which the “Normal” mode, thanks to the additional sensors involved, provides precise auto-hovering of the quadric, which novice pilots will appreciate more than ever. Also included in the kit were more productive and at the same time lightweight FPV goggles and a modified control panel, which, among other things, was equipped with a built-in capacious battery. By tradition, let’s start with the key features of the top RTF kit from BetaFPV.

Below you can read the key information BetaFPV Cetus Pro FPV Kit, which will allow you to learn more about the advanced FPV kit, as well as what improvements have been implemented compared to the predecessor BETAFPV Advanced Kit 2.

BETAFPV Cetus Pro

The BETAFPV Cetus Pro is a new micro quad model designed specifically for the BetaFPV Cetus Pro FPV Kit RTF. The list of key differences from its predecessor Meteor75 Light includes: a stronger monolithic frame (with a diagonal size of 78 mm, versus 75 mm of its predecessor), a more productive FPV camera, a sensor positioning system has been added (provides auto-holding of a position in Normal mode).

It is equipped with a proprietary BT2.0 type connector, which has proven to solve most of the problems of the PH2.0 connector common among micro drones, including the problem of voltage drop / drawdown.

BT2.0 connector

The BT2.0 type connector is a revolutionary type of connector for 1S micro drones, developed by BETAFPV engineers as a highly efficient alternative to the obsolete PH2.0 connector. Provides a significant difference in power efficiency compared to its predecessor. The developer notes the following advantages of the BT2.0 connector:

• Effectively reduces the internal resistance of the connector by upgrading the crimp contacts to 1mm banana connector and increasing its cross-sectional area.
• Solves the problem with a drop / voltage drop. Discharging LiPo battery with BT2.0 connector becomes more efficient. Pilots can enjoy longer flight times without the fear of overcharging their batteries.
• The battery with BT2.0 connector has stable current/voltage output and high efficiency. All 1S brushless drones get powerful and flawless performance from this type of battery.
• Ideal for Emax Tinyhawk series quads as the connector delivers consistent and consistent power, resulting in balance in dynamics and longer flight times.
• Compared with PH2.0 crimp contacts, BT2.0 connector is more durable, it can output more current for the same capacity and deliver much more power.

Comparison chart

Below you can see a comparison graph from the developer between BETAFPV 1S 450mAh 30C batteries with BT2.0 connector and Emax 1S 450mAh 80C batteries with PH2.0 connector. In this test, the discharge current is 11A. Obviously, a battery with BT2.0 has a longer discharge time and improved voltage drop, which results in better flight performance.

Power potential

The developer equipped the quad with a high-performance Lite 1-2S Pro flight controller with built-in 12A speed controllers, which in turn work in tandem with the time-tested 1102 18000KV brushless motors and 40mm 3-blade propellers. At the output, the Cetus Pro power plant provides, without exaggeration, exponential power and flight maneuverability for the occupied UAV niche.

Altitude hold function

Thanks to the built-in sensor system (optical sensor/barometer/laser), this quadcopter can automatically hold the altitude when the pilot’s hands do not touch the control sticks. The sensor system provides accurate and confident positioning, making this model stable even in tight flying conditions. Altitude Hold is only available in N (Normal mode).

self defense

The developer added a self-protection function to the quadric, which automatically activates an emergency landing in the event of a loss of communication or insufficient voltage. It will also automatically stop the motors when it hits an object.

Turtle Mode

If the quadric turned over, then it is not at all necessary to run towards it in order to turn it into a flying state. For this case, the developer added the “Turtle or Turtle mode” mode to the drone system, which allows you to remotely turn it over by switching the toggle switch on the control panel. It is also noted that turtle mode will not work effectively if something is stuck in the motor/guard ring. In this case, it is recommended to immediately exit the turtle mode using the SD toggle switch on the control equipment. Learn more about Turtle Mode in the Advanced Settings section below.

Flight modes

There are three modes available N mode (Normal mode)/S mode (Sport mode)/M mode (Manual mode), which smoothly reveal the flight potential of the quadric and thus fully meet the needs of pilots with different levels of training. In other words, whether you’re an experienced FPV pilot or a complete beginner, the Cetus Pro FPV kit will help anyone fly confidently from day one.

You can switch between these modes with just one SB toggle switch on the control equipment (see the section below “Assignment of controls”). Meanwhile, all these modes support 3 speed modes SLOW(Slow)/MID(Medium)/FAST(Fast). To change the dynamics of the flight, it is enough to switch the SC toggle switch on the remote control to the desired position:

1. N mode (Normal mode) — in this mode, the auxiliary hold position function is active. The quadcopter will maintain a fixed altitude when both joysticks are in the center position. The flight angles are minimal, the response to the movement of the control sticks will be smooth. When the mode is activated, the display of the FPV goggles will show “N MODE”. The mode is relevant for beginners. The developer reminds that the sensor system responsible for fixing the position of the copter operates in the height range from 0.3-3 meters.
2. S mode (Sport mode) — in this mode, the position hold auxiliary function is disabled. The pilot will need to control the flight altitude with the throttle stick (default left stick) and the horizontal position with the direction stick (default right stick). The flight angles will become larger, the response to the movement of the control sticks will be sharper. When the mode is activated, the display of the FPV goggles will show “S MODE”. This mode features more dynamic and complex controls and is suitable for the experienced pilot.
3. M mode (Manual mode) — in this mode, the position hold auxiliary function is disabled. The pilot will need to manually control the height and position of the quadric. Acrobatic flight becomes available. This mode features even more complex controls and requires a lot of practice to master.

Changing speed modes

The quadcopter flight speed threshold can be changed in all three of the above flight modes using the SC switch on the control panel:

On/Off touch system

In N-mode, the quadcopter position hold assist function is enabled by default, thus providing a novice piloting aid. You can disable this feature if necessary. To disable/enable the touch hold position function, do the following (use the remote control to access and navigate the OSD menu of the FPV goggles):

1. Turn on the remote, FPV quad and FPV goggles.
2. From the main menu of the FPV goggles, select “CONFIG” and enter the “CONFIG” menu as shown below.
3. Select “OPF” and change “ON” to “OFF” (Disable Touch Positioning)/ON (Enable Touch Positioning), then select “BACK” to exit the “CONFIG” submenu.
4. Select “SAVE” in the “MAIN” menu to exit the OSD settings menu.

For more details on how to interact with the OSD, see the “VR02 FPV Goggles/On Screen Display (OSD)” section below.

Charger

According to the stated specification, each drone battery provides 4-5 minutes of smooth flight. A low battery will be indicated by a warning in the OSD interface “LOW VOL”, and the LED on the quadcopter itself will flash red.

Charging steps are as follows:

1. Connect the charger to the Type-C port using the included USB cable.
2. Connect one or two batteries to the port to the right of the charger. The red charging indicator will indicate the charging process. Charging is complete when the charger LED turns green.

Two batteries can be charged at the same time. Charging a fully discharged battery takes about 20 minutes. If the battery is inserted into the “TEST” port, and the USB cable is not connected to the charger, the charger works as a voltmeter, through which you can measure the current battery charge level, where a reading of 4.30V indicates a fully charged battery, and 3.30V indicates a low level charge.

VR02 FPV Goggles

The VR02 FPV Goggles are the second iteration of FPV goggles specifically designed for the beginner audience, featuring simpler and more intuitive functionality than the advanced versions. Like its predecessor, it is built on a 4.3-inch high-brightness HD LCD display with a resolution of 800 × 480 pixels, paired with a high-quality lens with a transparency of 92%, providing a 2.8x increase in FPV images without distortion and blur. Unlike its predecessor, VR02 received a lighter body, as well as built-in high-quality 5.8 GHz antennas with a gain. gain of 14 dBi, which allows you to get stable and clear images even at maximum flight distances.

Turning on the FPV Headset

To turn on the FPV headset, do the following:

1. Slide the power switch to the right. The screen will light up and the FPV goggles will turn on.
2. Press and hold the “S” button for 1 second to turn on the quick search function of the operating frequency. After 3 seconds, a beep will sound and the glasses will display a live video stream, indicating the end of the search. VR02 FPV Goggles are ready to go.

On Screen Display (OSD)

After searching for a frequency, the flight information and the FPV image broadcast from the quadric will appear on the display. All of this flight information is part of the on-screen display (OSD). In the flight version of the OSD display, it looks like this:

Taken as a whole, the OSD is a set of operating interfaces designed to change the configuration of the quadcopter.

How to interact with OSD

To enter the OSD menu, you need to turn on the control equipment, quadric (without starting motors) and FPV goggles. Then, on the remote control, move the control sticks to the positions as shown below. The throttle stick (default left stick) moves left center, and the direction stick moves up center:

Important! Make sure the quadcopter motors are stopped before entering the OSD menu. SA switch in down position. The display shows “DISARM”.

After accessing the OSD, the pilot will see the following interface on the FPV Goggles display:

The OSD cursor can be controlled with the right stick:

• Up: to move the cursor up
• Way down: to move the cursor down
• Right: confirm/change selection

As you can see, for this quadric OSD model, the menu includes two main sections CONFIG and LAYOUT:

CONFIG

In this section, the pilot can control the sensor settings, LED backlight and, if necessary, calibrate the gyroscope.

1. TOF (On/Off laser position sensor)
2. OPF (On/Off Optical Position Sensor)
3. LED (Turn On/Off the Aircraft RGB LED)
4. CALI (Gyro calibration)

LAYOUT

In this section, the pilot will be able to add/delete flight information displayed on the display of the FPV goggles during the flight:

1. VOL (Current Aircraft Battery Voltage)
2. MODE (Airplane mode)
3. TIME (Flight time)
4. SPEED (speed mode)

Charger

VR02 FPV Goggles are equipped with a built-in 2000 mAh battery. When its voltage drops to 3.55V, a beep will sound every 10 seconds, indicating that it needs to be charged. You can also press the “S” button to check the current voltage of the built-in battery. To charge the battery of the FPV goggles, do the following:

• Turn off FPV goggles.
• Using the included USB-C cable in tandem with a charging power bank, for example, with which you usually charge your smartphone, charge the headset.
• The LED indicator glows blue while charging and turns off when it reaches 100% charge.

Remote LiteRadio 2 SE

GETFPV LiteRadio 2 SE is an updated control equipment implemented specifically for BetaFPV RTF kits. In the list of key improvements over its predecessor LiteRadio 2:

• USB-C port
• Built-in 1S 1000mAh battery (LiteRadio 2 SE extends max. operating time to 8 hours; max. operating time of LR 2 remote control: 3 hours)
• Built-in charging module, control equipment upgrade with BETAFPV’s LiteRadio system (pilots can directly control stick calibration and firmware upgrade)
• Extended list of supported Frsky/Futaba/Bayang protocols (pilots can easily switch between the available Futaba, Frsky D8, Frsky FCC D16 and Frsky LBT D16 protocols directly from the remote controller)
• Increased transmitter power to 100 mW (predecessor transmitter power: 80 mW).

comparison table

We bring to your attention a comparative table of key changes between the updated LiteRadio 2 SE equipment and the previous version of LiteRadio 2:

How to switch protocol

To change the protocol (Frsky FCC D16, Frsky LBT D16, Frsky D8 or Futaba S-FHSS), you must first turn off the power of the remote control, then press and hold the BIND button when turning it on again. After that, the flash time of the red LED before the sound signal will change, which will inform which protocol the control equipment has switched to.

Appointment of governing bodies

Button assignment

There are three buttons on the remote control:

1. BIND Button: A short press will activate the pairing mode of devices (Aircraft/Remote). If during operation the drone loses connection with the remote control, this button solves the problem.
2. SETUP Button: A short press will activate stick calibration mode. It is performed by a short press immediately after turning on the remote control.
3. Power On/Off Button: Turns on/off the remote control when long pressed.

Charger

The LiteRadio 2 SE control equipment is equipped with a built-in 1000 mAh battery. A low battery level will be indicated by a slow flashing blue LED. To charge the remote control battery:

• Switch off the control panel.
• Using the supplied USB-C cable in tandem with a charging power bank, for example, with which you usually charge your smartphone, charge the control equipment.
• The LED indicator glows red while charging and turns off when 100% charge is reached.

FPV simulator support

The LiteRadio2 SE remote control can be used as a USB joystick when connected to a computer, which allows you to easily practice piloting skills in a virtual environment through various FPV simulators, for example, when it is bad weather outside. By the way, while you are exercising, the remote will be charging.

Quick Start

Before flying, make sure the remote controller is successfully connected to the quadcopter, all the main controls are functioning, and the quadcopter can take off smoothly:

• Step 1. Set the throttle stick (default left) and four switches (SB/SA/SC/SD) on the remote control radio to the lowest position. Press and hold the power button on the remote control for 5 seconds until it beeps three times, then release. The remote control’s power indicator will flash red quickly and then change to blue to indicate that the power is on.
• Step 2: Install the battery in the battery holder under the quadcopter. Make sure the battery power cable and quadcopter power cable are on the same side. Connect the quadcopter to the battery, then place the quadcopter on a horizontal surface. Wait 3-5 seconds until its status LEDs change from flashing blue to solid blue. This means that the initialization of the quadcopter is completed and the quadcopter is successfully connected to the remote control.
• Step 3: Move the SA switch up to turn on the quadcopter. The throttle stick (left by default) must be in the lowest position, otherwise the quadcopter will not turn on! The motors will start spinning slowly. Move the SA switch down, the motors will stop.

Completing these steps confirms that the quadcopter and remote control are working properly, so you can proceed to fly.

Piloting

Start the drone’s motors (Step 3). The motors will rotate at low speeds, but the quad itself will not take off. Slowly move the throttle stick (left by default) up to lift the aircraft into the air. In N-mode, the quad will hold position automatically even if the pilot releases the control sticks. Further details on the purpose of each of the sticks:

Throttle stick (default left stick)

Direction stick (default right stick)

Landing

Land in a stable and smooth descent. After the quad has landed, turn off the motors by switching the SA-toggle switch on the control panel, as shown below:

Disconnect and remove the battery from the quadcopter. A long press of the power button on the remote control will turn it off after three beeps.

LED backlight status

Drone

At the bottom of the drone, there are two RGB LEDs that reflect the current state of the drone:

Status status table based on the color of the RGB LED backlight of the copter

fpv goggles

Between the USB-C port and the power button, there is a blue LED status indicator that indicates the status of the FPV headset:

Remote Control

There is a blue and red LED light around the power button that shows the status of the remote control:

Status status table based on the color of the RGB LED backlight of the control panel

Sound accompaniment

In addition to LED status indication, the so-called buzzer is built into the console, by the sound of which the pilot can determine the operating state of the control equipment:

Advanced settings

Additionally, in the drone system, the developer has laid down a number of advanced settings that will be relevant for solving some problems that arise during operation.

Turtle mode

When the quadcopter hits the ground and rolls over, you don’t have to run towards it. To turn it over, it is enough to activate the “Turtle mode / Turtle mode” by switching the toggle switch on the control panel. To activate turtle mode, do the following:

1. Move the SD switch on the remote controller from the bottom position to the top position. The FPV goggles will display the logo “turtles».
2. Now move the direction stick (right stick by default) in any direction. The motors of the quadric will begin to rotate and it will independently turn over to the flight position.
3. Flip the SD switch down to turn off Turtle mode. Start the engines and continue flying.

Note: Turtle mode is suitable for flat ground. The developer does not recommend activating it on grass or fabrics with a long pile, otherwise, with a greater degree of probability, the operation of the motors will be limited or blocked altogether, which will lead to the failure of the power plant.

Re-pair devices

If the quadcopter and remote control cannot connect successfully, the pilot may need to re-pair/pair the devices. Typically, this can happen when replacing the electronic components of the quadcopter during maintenance, as well as as a result of upgrading the radio transmitter of the remote control. To link devices, do the following:

1. Turn on the quadcopter and wait for its system to fully boot.
2. Using a screwdriver, lightly press the button on the quadcopter, and the status LEDs on the quadcopter will change color to green and start blinking.
3. Turn on the remote control and wait for the system to boot completely.
4. Lightly press the BIND button on the back of the remote control with a screwdriver. The power indicator will blink red.
5. If the device pairing process is successful, the quadcopter status LEDs will change to blue.

Note: Rebinding the remote control radio transmitter to the aircraft may not complete successfully after pressing the BIND button on the remote control radio transmitter once. In this situation, the pilot must press the BIND button a second time to complete the binding.

Gyro calibration

Takeoffs, landings, minor crashes/accidents during the operation of the quadcopter inevitably have a negative impact on the operation of the gyroscope. Incorrect operation of the gyroscope leads to the fact that the quadrocopter in flight will spontaneously tilt/shift to one side. To fix this, the quadcopter gyroscope can be calibrated. The steps are:

1. Turn on the quadcopter, remote controller and FPV goggles. Make sure the connection is established.
2. Place the quadcopter on a horizontal surface.
3. Enter the OSD menu of the quadcopter (refer to the On-Screen Display (OSD) section).
4. From the main menu, select CONFIG, then CALI.
5. Move the direction stick (right stick by default) to the right to start the level calibration mode. The quadcopter LED flashes blue.
6. The end of the calibration process will be indicated by an OK message and the aircraft LED will change from flashing blue to solid blue. The pilot can exit the OSD.

Remote Control Calibration

After repeated use, or if the remote control has been subjected to physical impact, the control equipment’s sticks may no longer read the correct readings, which may require recalibration. To do this, do the following:

1. After turning on, press the SETUP button on the back of the remote control, when pressed, the control equipment will emit two beeps, and the LED indicator around the power button of the remote control will flash red twice quickly. The remote control has entered calibration mode.
2. Move the throttle stick (default left stick) and direction stick (default right stick) to the center position. Press the SETUP button again and wait until the remote control beeps three times. The red LED will flash twice quickly. This means that stick center data has been received.
3. Slowly move the throttle (left stick by default) and direction (right stick by default) stick twice in a circle to their maximum positions (once counterclockwise and once clockwise), then press the SETUP button again. The remote control will beep for about 3 seconds and the LED will stop flashing. Calibration completed successfully.

OPF control

In flight mode “Normal; Normal mode”, Optical Flow Positioning (abbr: OPF) is enabled by default, which automatically holds the position of the copter, thus making it easier for a novice user to take the first steps in learning to fly. To enable/disable the OPF function, do the following:

1. Turn on the quadcopter, remote controller and FPV goggles. Make sure the connection is established.
2. Enter the OSD menu of the quadcopter (refer to the On-Screen Display (OSD) section).
3. From the main menu select CONFIG and go to the CONFIG menu as shown below.
4. Select OPF and change the value next to the function name: OFF (disable positioning)/ON (enable positioning), and then select BACK to exit the CONFIG submenu.
5. Then select SAVE from the MAIN menu to exit the OSD setting interface.

Note: The OPF function of the Centus Pro quadric is built on an optical sensor, the correct operation of which depends entirely on optimal lighting.

TOF control

In flight mode “Normal; Normal mode”, the laser height detection function is disabled by default. Enabling this function can make the hovering of the aircraft more accurate, and it can also maintain a fixed relative height in relation to the ground and/or ground objects, thus allowing the aircraft to automatically rise in height in flight when the ground is uneven or obstacles, thereby making it easier to for a beginner, the first steps in learning to fly. To enable/disable the TOF function, do the following:

1. Turn on the quadcopter, remote controller and FPV goggles. Make sure the connection is established.
2. Enter the OSD menu of the quadcopter (refer to the On-Screen Display (OSD) section).
3. From the main menu select CONFIG and go to the CONFIG menu as shown below.
4. Select TOF and change the value next to the function name: OFF (disable the function)/ON (enable the function), and then select BACK to exit the COFIG submenu.
5. Then select SAVE from the MAIN menu to exit the OSD setting interface.

pros

• Execution quality
• Safe flight (frame with ring protection) Indoor and outdoor
• Factory tuned to racing standard
• Powerful B/C motors
• Controllability
• Auto hold mode
• Enhanced crash resistance
• Improved call quality
• Lighter and more comfortable FPV headset
• Built-in battery in the remote control (operating time on a single charge up to 8 hours)

Minuses

• No built-in DVR
• FPV camera (good FPV picture only with optimal lighting)

A high-quality iteration of the previous top FPV kit, which received a number of noticeable improvements affecting both the product itself and its flight qualities. In particular, the impact resistance of the main frame has been improved. At the same time, it has become not tougher, but more flexible, thanks to which it is able to forgive the numerous accidents of a novice pilot without fear of harm, which is also an important factor. Improved aspects affecting the comfort when wearing FPV goggles, the headset has become lighter and now it is comfortable to pilot in it (unlike the previous headset, the area around the nose no longer creates discomfort). The control equipment received a built-in battery, which provides eight hours instead of three hours.

Field tests have shown that the quality of communication and the transmitted FPV picture have become noticeably better. Piloting in first-person mode at maximum distances, or through several rooms, is much better than the potential of its predecessor. The calling card of the quadric is the added position hold function implemented for this model through a pair of sensors. This is not to say that the function works perfectly, but it will definitely come in handy for the most insecure pilots. The bundled power supply provides about 3 minutes of flight in the “throttle to the floor” mode and about 4.5 minutes in the “cruise” mode, and therefore we strongly recommend that you purchase additional batteries (at least four more batteries).

The main disadvantage of the extended kit is the lack of a built-in video recorder (DVR) in FPV glasses. An FPV camera is good only as long as the ambient lighting is optimal, so the less light, the more noise on the screen of the FPV headset. Due to its light weight and frame design, the quad does not like windy conditions, but due to the potential of brushless motors and advanced piloting experience, it still allows you to confidently cope with the presence of wind.

To summarize, the updated BetaFPV Cetus Pro FPV kit is a well-executed and finished product. Includes all the necessary components for the safe operation and transportation of the copter. Extremely easy to use. Does not require pre-configuration – charged and flew. First of all, the kit is designed for entry-level users. Due to its inherent potential, it is excellent as a simulator for practicing piloting skills in professional modes (Acro/Manual). Age limit 8+.

FAQ

Q. How to change propellers?
A. Use the wrench provided to remove the propellers. Grab the motor when removing the propellers. This approach will eliminate the deformation of the frame from overvoltage.

The kit includes 4 spare propellers: two CW-direction propellers (ClockWise; clockwise) and two CCW-direction propellers (CounterСlockWise: anti-clockwise). CW propellers spin clockwise. They are mounted on the rear left or front right motor. CCW propellers spin counterclockwise. They are mounted on the rear right or front left motor.

Q. How to fix quadcopter drift when piloting in Normal/Normal flight mode?
A. In flight mode “Normal; Normal mode”, the optical flow positioning function (OPF) of the Cetus Pro quadrocopter is enabled by default. However, it is worth considering the fact that the OPF function is built on an optical sensor, the correct operation of which entirely depends on the compliance of the environment with optimal operating conditions. In particular, optimum illumination must be ensured, and the ground surface must also be distinguishable/non-homogeneous. Otherwise, the quadcopter may drift or be difficult to control. The following are common unsatisfactory operating conditions under which the aircraft with the optical sensor enabled (OPF function) will behave incorrectly in piloting:

• Dark homogeneous environment
• Above the surface of the water
• Smooth or plain surface

If the quadcopter needs to fly in unsatisfactory environmental conditions, the optical flow positioning function (OPF) can be disabled, which will prevent automatic position holding. This will require the best piloting skills from the user.

Similar restrictions apply when the laser altitude detection (TOF) function is enabled, so try to avoid the following unsatisfactory operating conditions:

• Environment with strong sunlight or with clear changes in light and dark
• Homogeneous black earth
• Highly reflective ground surface, etc.

To enable/disable the Positioning Function (OPF) or Laser Height Detection Function (TOF), see the Advanced Settings section above.

Make sure that the bottom of the sensor is not blocked by anything, and that there is no dirt or dust on its surface, which may affect the accuracy of operation. If the flight assist function is not working properly, the sensor should be wiped down before the quad is put into operation.

Q. How can I connect the remote control to a computer for virtual piloting with an FPV simulator?
A. The Lite Radio 2 SE remote control supports most FPV simulators on the market thanks to its universal configuration. To connect the control equipment to the computer, do the following:

1. Turn on the remote and wait until the blue LED lights up.
2. Connect the remote control to the PC using the supplied USB-A ⟷ USB-C cable.
3. The required driver will be installed automatically. A window will appear confirming successful installation.
