Introduction to Tiny Whoop for beginner: How to fly Cine Whoop / Tiny Whoop / FPV droneThere is a category of drones called Tiny Whoop / FPV drone / Micro Whoop / Cine Whoop / Racing drone. Equipped with a powerful motor in a lightweight body, used for aerial photography with an action camera on its back or for drone racing. Here, we have summarized the basic information to take the first step in this world of Tiny Whoops / FPV drone.

What is Micro Whoop / Cine Whoop / Tiny Whoop / FPV Drone?Equipped with a powerful motor in a lightweight body, you can fly at high speed and perform a powerful maneuver. Image of the camera mounted on drone (FPV image) is projected onto goggles for maneuvering. You can mount an action camera to shoot a movie with a sense of speed, perform aerobatics such as sharp turns and somersaults, and participate in drone racing. In addition, small model is palm-sized, so you can enjoy flying even in a small house. Ideal for hobbies during the stay home era.
However, because it's high-power motors compared to it's lightness, maneuvering is extremely severe, and maneuvering feeling is completely different from that of Self-leveling aerial photo, video drones such as DJI and Parrot. You can't fly freely as soon as you buy it. It takes a lot of practice to get the flight you want.
Video shot with FPV WhoopsLet's start with some of the amazing aerial videos shot with FPV drones.
The first video below was taken by Swedish microdrone pilot Matin Hamarahem early Sunday morning in the heart of Stockholm with special permission ( Related article (dronedj) ).
Matin Hamarahem has published many other aerial shots with FPV drones. An aerial video of Erbil Downtown (YouTube) in Iraq is also recommended.

What you need to enjoy Tiny WhoopsTo enjoy Tiny Whoops, you need something like the following:
- Controller / Radio
- Controller / Radio for radio-controlled model is used to control Tiny Whoop. There are several protocols (communication methods) for control it. You need to get a Radio that supports the protocol that drone you want to fly has.
- Prices start at around USD100, and for high-performance, large-scale machines, it costs USD300 to USD400 or more. Weights also range from tens to hundreds of grams, depending on the model. Not only can you buy finished product, but you can also assemble parts yourself. At first you will crash many times, so it is recommended to practice on a small aircraft that is cheap and has replacement parts for repair.
- FPV goggles
- Put it on your head, receive the image from the camera mounted on the drone, and use it for maneuvering. Tiny Whoops are small and fly at high speeds, so it's almost impossible to control them from a ground perspective like drones for aerial photography. FPV goggle is must have item for Tiny Whoop pilot.
- Radio worker license
Video transmitter (VTX) installed in Tiny Whoop uses amateur radio waves in 5.8GHz band, so license is required to use it in Japan.
Two licenses are required: a radio operator license for pilots and a radio station license for video transmitters (VTX).
In the United States, amateur radio license (HAM license) is required when using a VTX with an output exceeding 25mW, or specific band or channel in 5.8 GHz band.
- Crafting skills
- It is better if you have the skill of crafting that can be repaired when it is damaged by a crash or the wiring is broken. In particular, please acquire basic electronic work knowledge and soldering skills. Many Tiny Whoops need to be adjusted and repaired after purchase. Conversely, adjustment and repair are also one of the pleasures of Tiny Whoops.
Choose Controller / RadioGet the Controller first. As long as you have a Controller, you can start practicing maneuvering using drone simulator on your computer. The information required to select a Controller is the protocol used to communicate with the drone and whether or not a "TELEC certification" has been obtained, which indicates that it complies with the Radio Law in Japan.
There are various protocols for control signals sent from Controller to Drone. You don't have to understand the protocol specifications, but you need to make sure that the protocol matches between Drone and Controller you want to fly.
Most Tiny Whoops use one of the "Frsky", "DSMX" or "Flysky" protocols. It is certain to get a Controller that supports these three. Nowadays, you can get a Controller that supports multiple protocols for about USD100. Alternatively, some Controller can have an optional multi-protocol module added.
Among them, "Frsky" is the most popular protocol. When in doubt, it's a good idea to choose a drone and Radio that supports "Frsky."
In addition, "Frsky" is further classified as a subtype, and subtype "D8" is banned in Europe since 2015, and mandatory to use protocol called LBT (Listen Before Talk) in subtype "D16". For this reason, there are two models of drones / radios that support "Frsky", "Frsky Non-FCC / Frsky LBT" for Europe and "Frsky FCC / Frsky Non-EU" for other regions.
Confirmation of acquisition of "TELEC certification" (in Japan)
In order to use a device that emits radio waves in Japan, the device must have TELEC certification (Ministry of Internal Affairs and Communications) . The certification is usually obtained by the manufacturer or importer applying to the Ministry of Internal Affairs and Communications, and "TELEC mark" is attached to the product as shown in the figure.
Users must choose Controller with this "TELEC mark". Alternatively, although it takes time and money, you can apply for TELEC certification yourself.
Radio used for Tiny Whoop runs on open source firmware. Some settings need to be made before flight is possible. Depending on the product, it may be necessary to start by installing firmware. Various settings and adjustments can be made by connecting PC and Radio with USB cable, and using firmware companion software (Configurator).
In recent models, it seems that OpenTX is often adopted as the firmware. Information providing sites OpenTX University and RCdiy has more information on how to configure Radios with OpenTX. Also please refer How to use OpenTX Radio page.
Controller and Drone must first perform an operation called "bind" that connects them to each other. You can bind multiple receivers (drones) to one Radio and switch between them for maneuvering, but one receiver can only bind to one Radio. When you bind to a new transmitter, it will be unbound from the transmitter you were using.
To bind, first start the drone in bind mode, then perform the bind operation on the Controller side. This procedure varies for Controller and Drones. Please read each manual carefully before operating.
Arm / Disarm
Enabling operation of drone is called Arm. After binding and turning on radio and drone, turn on Arm switch on radio to enable operations such as sticks. If you feel a danger, you can drop drone on the spot by intentionally turning off Arm switch.
Normally, Arm cannot be performed unless throttle is set to zero and aircraft is level.

How to use OpenTX Radio
Choose DronesVideo shooting, indoor leisure, participation in drone racing ... I think there are various purposes for flying a Tiny Whoop, but you should not buy the high-priced machine you are looking for from the beginning. By the time you're free to fly your microdrone, you'll have to crash it over and over again. I recommend that you first purchase a cheap, sturdy, and beginner-friendly item for about USD100 and practice thoroughly. For beginners, Emax's Tinyhawk and BetaFPV's Meteor series are famous. Today, so many manufacturers are making and selling FPV drones / Tiny Whoops. Please refer to " Related links " for a list of some of them.
Checking installed communication protocol
The same model may be available in multiple versions with different protocols. At the time of purchase, make sure that version of the product has desired communication protocol. Also, depending on drone, receiver may not be installed (denoted as PNP). In this case, you need to purchase a receiver of your favorite protocol suitable for the drone separately and install it yourself.
Represents the size of Tiny Whoop. It is expressed by the distance (mm) of central axes of two motors in diagonal positions. In Tiny Whoop, there are usually four types, 65mm, 75mm, 85mm and 95mm. 65mm has a small output and is suitable for indoor flight. If you want to fly outdoors, we recommend 75mm or more. I think it's a good idea to start with 65mm or 75mm model for Beginners.
|75mm||40mm||both indoor and outdoor|
|85mm||50.3mm (About 2 inches)||outdoor|
|95mm||63.5mm (About 2.5 inches)||outdoor|
Battery output voltage / capacity
The output voltage of a LiPo (lithium polymer) battery is determined by the number of cells. Regardless of the size, it will be about 3.7V (4.2V when fully charged) for one cell, about 7.4V for two cells, and so on. At first, choose a 1-cell (1S) type low-power drone.
Battery life is also indicated by capacity (mAh). If you install a battery with a large value, you can fly for a long time, but it will also increase the weight, which is disadvantageous for flight.
For more information, see Long-lasting and reviving drone batteries .
Video transmitter (VTX) and FPV camera
The transmission output of VTX is usually 25mW, but some models can be switched to 200mW, 500mW or more. Since the radio waves used are in 5 GHz band, if there are obstacles such as walls, radio waves will hardly reach. If you want to fly around in your house, you should stand in the center of building as much as possible and open all doors. Alternatively, replace with higher gain antenna or use higher output VTX.
Also, some drones do not have a video transmitter (VTX) and camera. In this case, you need to purchase the one that fits the drone separately and install it yourself.
Digital VTX VS Analog VTX
Normally, VTXs for drones transmit NTSC / PAL format analog video signals, but DJI Digital FPV System (DJI) and its compatible Caddx Digital VTX series (Caddx) transmit their own digital signals. This digital signal ensuring a clear, noise-free field of view, but cannot be seen with regular FPV goggles. DJI's " DJI FPV Goggle (Amazon.com) " (not yet released in Japan) is required for it. Please pay attention to the specifications of VTX when purchasing a drone.
Fat Shark has also released its own digital VTX Shark Byte series (Fat Shark) .
Tiny Whoop runs on open source firmware. By connecting FC (Flight Controller) board of drone to PC with USB cable, and using companion software (Configurator) of firmware, it is possible to adjust the flight characteristics and so on. In recent models, Betaflight is often used for FC firmware, and BLHeli_S is used for ESC (Electric Speed Controller) firmware.
Please note that some FC boards for beginners or lightweight models do not have a USB connector (cannot be adjusted by user).
Depending on drone, you can switch between multiple flight modes, such as flight stability-focused mode ( Angle / Level / Stab ), mode that allows for somersault with a high degree of freedom in posture ( Horizon ), aerobatics mode ( Acro / Rate / Manual ), and racing mode (Race) (the name depends on installed firmware). At first, practice in a mode that emphasizes flight stability. However, if you do not use the aerobatics mode, your flight will not improve. It is recommended that you switch to practice in aerobatics mode as soon as you get a feel for the maneuver.
For more information, see Tiny Whoop Flight Mode:Angle/Horizon/Acro/Air .
When the drone is turned over, it is a function to get up by rotating one of the front and rear or left and right propellers at high speed. With a drone equipped with this feature, you don't have to turn over by hand. Normally, you can operate the switch on the controller to switch the drone to turtle mode and operate the elevator or aileron on the stick to get up. Also known as “Flip Over After Crash”.
On the screen of FPV goggles, on top of the image from the drone's camera, information such as remaining battery level and flight mode of the drone are displayed. This is called OSD (On Screen Display). The information displayed on OSD and its display position can be set with the drone's firmware companion software. You can also enter the drone setting screen by starting drone and operating stick in Throttle center, Rudder left most, Aileron center, Elevator full up with Disarm. On the setting screen, you can move cursor by operating right stick up and down, "Enter" / "Select" by operating the right stick to right, and "Return" by operating to left.
Opening of radio station (in Japan)
Video transmitter (VTX) mounted on the drone transmits radio waves of amateur radio in 5.8 GHz band. In Japan, it is necessary to apply for this video transmitter (VTX) as a "radio station" and obtain (open) a radio station license. If you transmit radio waves without a license, you will be punished with imprisonment for up to 1 year or a fine of up to 1 million yen.
To apply for a radio station license, it is necessary to attach a "construction design document" that shows the block diagram of the transmitter. Select a product whose block diagram can be downloaded from the manufacturer's site.
No license is required for receiver: RX. For this reason, FPV goggles do not require a license.

Choose FPV gogglesMicrodrone video transmitters (VTXs) typically transmit video at one of the following frequencies. The frequency to be transmitted is selected using the drone setting function, or is automatically set when the drone (VTX) is started.
Electrically, it's just a video receiver, so if you prepare multiple goggles, you can enjoy the flight image of one drone with multiple people.
Receiver and antenna
Antennas come in a variety of shapes and can be replaced and used as long as the connector type matches. There are multiple types of antenna connectors, such as SMA, RP-SMA, U.FL(IPEX/IPX) and MMCX, so be careful when purchasing.
Video receivers (RX) and antennas are sold separately for high-end models. Select the receiver and antenna that can be attached to the selected goggles.
For more information, see Knowledge of Tiny Whoop antennas .
The display resolution of FPV goggles is only about 800x480 pixels for beginners and about 1280x960 pixels for high-end models, which is lower than recent smartphones. However, in general, the resolution of camera mounted on FPV drone is about 600TVL to 800TVL for horizontal scanning line, so it can be said that 800 pixels in vertical direction is sufficient for resolution of FPV goggles.
DVR (Digital video recorder) function can record the video displayed on the goggles. Normally, insert the micro SD card into the goggles and press the record button on the goggles to start recording. Not only will you enjoy the flight later, but you can also use it to pinpoint the location of the crash if you crash outdoors and the drone goes missing. Goggles that normally have a DVR function also have a Playback function.
Depending on model, it may be necessary to prepare a battery separately. FPV goggles consume power, so if you have a model that can use an external battery, you can enjoy it for a long time by preparing a replacement battery or a large capacity battery.
How to substitute VR goggles for smartphones
If you have an Android smartphone that can connect to OTG, you can also use inexpensive VR goggles (Amazon.com) for smartphones by connecting EACHINE ROTG01 FPV receiver (Amazon.com) .
Note that iPhone series does not have the ability to display external video input, so such accessories are not manufactured either.
How to substitute with TV

Put the camera on / Cine WhoopTiny Whoops with recording cameras, especially for aerial photography, are sometimes referred to as Cine Whoop.
Originally, FPV camera installed in microdrones has a low image quality, and when recording with recording function (DVR) of FPV goggles, noise enters because it goes through radio waves. To get clear, high-quality aerial video, you need to have a recording camera on your drone.
Drones with recording function
From around 2018, several models of micro drones with recording function, such as Eachine Cinecam, Happymodel's Mobula 7 HD and Mobula 6 HD, iFlight Cinebee, BetaFPV Beta85X HD and Beta75X HD, Meteo65 HD , e.t.c. have appeared. Since stability is more important than power, many models are equipped with slightly lower output 2S to 3S batteries and have four blades as propellers. Some have a 4K recording function. With these models, you can easily enjoy aerial photography.
Drone with action camera
If you want higher quality recording, you need to equip your micro drone with an action camera. There are FPV drones that can be equipped with action cameras such as GoPro and Insta360 ONE R as they are, but the size of the aircraft is large and the weight exceeds 250 g, not possible to fly alone under the Aviation Law (visual observer is required) , so it is a little out of the category of drones for beginner.
Make Naked Camera
You can disassemble an action camera such as GoPro to make it smaller and lighter, and put it on a drone to shoot aerial video. This act is also called Naked Camera because it dismantles the camera and strips it naked, and there are forums that talk about it. BetaFPV sells boards and cases for attaching GoPro HERO6/7/8, which has been transformed into a Naked Camera, to a drone. Of course, the action camera transformed into a Naked Camera is no longer covered by the manufacturer's warranty, and no one will compensate for it if it breaks down. All must be done at your own risk.
Drones with small camera
A small camera that can be mounted on a Tiny Whoop as it is has finally been released recently, like insta360 GO 2 (insta360.com) . In addition, on December 19, 2020, a 4K 60FPS action camera weighing 30 grams SMO 4K Camera was released in collaboration with insta360 and BetaFPV. It does not have a built-in battery and is powered by drone's battery.
The video below is published by BetaFPV and was shot with SMO 4K Camera on Beta95X V3 (BetaFPV) Tiny Whoop. Beta95X V3 comes with a dedicated mount for SMO 4K Camera.

Checking drone flight rules : Are FPV Goggles Illegal?Many Tiny Whoops weigh less than 250g, which greatly relaxes drone flight rules, but they don't allow you to fly anywhere. Make sure to check the drone's flight rules in advance so that you do not violate the law. Maneuvering with FPV goggles is not considered "visual range". Please note that flying FPV drone alone (without visual observer) violates the law (constant surveillance within visual range) in many countries.
At least how much practice do you need ?In my experience, after spending about 10 flights (10 batteries flight time), I finally flew around the room once and then crashed in Angle mode . After that, after about 20 flights, I was able to fly around the room several times and then crash. However, by that time, the drone's frame was cracked and tattered. It took me about four months to be able to fly freely inside house in Acro mode. In the meantime, I repaired camera disconnection once, battery connector disconnection twice, and replaced each of the four propellers once or twice, replaced the frame three times. If you are good at action games, you may improve faster.
I recommend you to start practicing indoors, as losing control is less likely to be damaged or lost. And since one flight time is as short as 3 to 5 minutes, I think it is good to prepare a lot of batteries. However, at first, due to the difficulty of maneuvering, you will feel tired and want to take a break after flying only about two batteries. I think it's a good idea to fly little by little at first and gradually increase the practice time. Also, use drone simulator on your computer to prevent damage to your drone. Below is a video of Serbian FPV drone pilot Vladimir Muncan's transcendental skill flight. ( Related article (dronedj))

Repair your droneRepeated crashes can damage the frame and propellers and break wiring. Get these spare parts on the official website of the drone maker. Also, prepare repair tools such as a precision screwdriver, soldering iron, and magnifying glass. Use a soldering iron for low-temperature electronic circuits of about 15 to 20 W.
Battery connector repair
Battery connector is one of the most deteriorated parts, as the battery is attached and detached each time you fly. In particular, the electronic parts of the micro drone connector are exposed and the strength is not considered so much, so handle it with care. The mail order site also sells spare connectors. If it deteriorates, replace it with a soldering iron. Instead of replacing from the base on the board, it is easy to cut the cable in the middle and add it by soldering.
Repairing camera wiring
If you can't see the camera image on the FPV goggles, suspect that the wiring between the camera and VTX board or between the VTX board and FC (Flight Controller) board is broken. If you can see the image when you press camera or VTX board with your finger, a poor contact has occurred and wire is about to break. Originally, the soldering of the product is quite omission, so it will easily break if it receives an impact. After repairing with solder, I think it's a good idea to harden the area around the terminals with a glue gun (Amazon.com) , it will be more resistant to shocks.
Or if the screen becomes noisy over time, suspect a possible overheat. The VTX board can become hot and malfunction in a relatively short period of time. In such a case, remove the battery from the drone and let it cool for a while. If you blow on the camera, the unit may cool and the image may come back.
|Immediately after applying a shock or strong force to drone, video screen disappeared or noise began to appear.||Wiring disconnection or poor contact between the camera and VTX board, VTX board and FC board||Find the broken part and repair it with solder|
|One day when you started drone, video screen disappeared, or radio wave range decreased, noise began to appear.||
The transmission band and channel of VTX have changed for some reason.
(Or battery of FPV goggles may be dead, antenna or goggles may break down ...)
|Run scan function with FPV goggles, or check / change drone's firmware settings|
|After starting the drone, if you leave it for a while, video screen disappears||VTX overheat||Remove battery from the drone and let it cool for a while|
Once the frame cracks due to a crash, the damage spreads from there, causing the frame to tear and fall off. Then, in the event of a crash, the propeller will be damaged and you will not be able to fly. If you find a crack in the frame, repair it immediately with tape or bond.
If you attach "corner guard tape" (double-sided tape on a sponge sheet) to outer circumference of the frame in advance, it will be relatively resistant to crashes. For 65mm model, sticking this on the "forehead" will make it easier to get up in turtle mode even on a slippery floor.
Anyway, frame is a consumable item. Let's prepare a lot of spares.

Knowledge of Tiny Whoop antennasTiny Whoop Video Transmitter (VTX) antenna come in a variety of shapes and can be replaced as long as the connector type matches. However, there are linear (Vertical / horizontal) polarization and circular polarization in the vibration direction of electromagnetic waves, and if polarization directions do not match between Radio and receiver, sensitivity will decrease. Since the attitude and direction of a drone constantly change, it can be said that circularly polarized antennas are more suitable for transmitter (VTX) than linearly polarized antennas.
A linearly polarized antenna becomes vertically polarized when it is erected vertically, and horizontally polarized when it is extended horizontally. In addition, there are structurally two types of Circularly polarized antennas. "RHCP (Right Hand Circular Polarization)" and "LHCP (Left Hand Circular Polarization)".
All of them are often used as antenna members for Wi-Fi wireless LAN in the 5GHz band, and cables and conversion connectors can also be purchased from Amazon.
