Introduction
After the success of the Hubsan X4 H111 mini quadcopter in 2014, we all expected to see something better from Hubsan. Instead of inventing a new model, they decided to improve on the old, popular X4 Nano H111. Meet the modified nano quadcopter — Hubsan H111D.
Peculiarities
- Weight: 17.8g
- FPV at 5.8GHz analog frequency without delay
- Heading FPV HD Camera (720P)
- headless mode
- 6 axis gyroscope
- For outdoor and indoor flying
- LED backlight
- 2.4GHz remote controller with built-in 4.3″ FPV monitor
- Max. flight time 6 min
- Max. removal distance 50 m
The lineup
2 drone options were presented:
- H111C (X4 Nano Plus) — with 720p camera without FPV
- H111D (Nano FPV Q4) — with 720p camera with FPV

Hubsan H111D Nano FPV Q4 is a versatile nano drone that has received almost all the main features of a drone in this niche. If we compare the popular Cheerson CX-10WD-TX and Hubsan H111D, the latter has a more advanced flight in first person mode (FPV), implemented at an analog frequency of 5.8 GHz, which does not have delays in video transmission. For the CX-10WD-TX, FPV flight is implemented over Wi-Fi, with the accompanying negative latency impact for this method.

Unboxing
The Hubsan H111D quadcopter comes in a stylish black box with a transparent window through which the quadcopter can be seen. The quality of the packaging deserves respect. In addition to a miniature quadcopter and a huge remote control, the box contains: USB charger, one set of spare screws and instructions. Unfortunately, the kit does not include a memory card, so you have to buy it separately. Suitable microSD card, from 4 to 8 gigabytes.

The first thing to start getting acquainted with the drone is to study the instructions, as it describes in detail how to prepare for the flight and how to control the drone during the flight. It also describes the details of the construction and gives a exploded view if the H111D needs to be repaired.
Appearance
Design Hubsan H111D inherited from its predecessor. All parts of the drone, including motors, are fixed on the main board. We attribute this fact as a minus, because in case of any serious accident, the entire board goes under replacement. Internal elements (camera, battery, receiver and transmitter) are hidden under a protective frame. The material is durable and lightweight ABS. Motors are easily removed, but soldering is indispensable. The battery is built into the body like most drones in this niche (without the possibility of quick replacement). On the back of the drone, under the charging port, is a tiny power switch. For better pilot orientation (front/back), the developer equipped the quadric with multi-colored propellers and LED lighting.





Motors

The Hubsan H111D quadcopter is equipped with collector motors standard for this UAV niche. The developer does not specify information about their power.
Camera

The Hubsan H111D FPV camera is integrated into the body and, as it turned out, has a very small viewing angle, which in turn complicates the control in FPV mode. The main task of such a camera is far from shooting, but first of all, high-quality FPV flight. This is also indicated by the fact that the video is recorded on a memory card (microSD is purchased separately), which is installed not in the drone slot (it is not there), but in the slot of the control equipment. The resolution of the recorded video is 1280×720p (HD). AVI video format.
Food

The quadcopter is equipped with a single-cell lithium-polymer battery with a capacity of 180 mAh. According to the manufacturer’s specification, it provides a flight time of up to 6 minutes. In practice, with a mixed style of piloting, this time was standard for this niche of 3–4 minutes. During this time, the drone has time to warm up quite a bit due to the operation of the receiver with the transmitter.
Remote Control
The Hubsan H111D quadcopter is equipped with the most common control equipment, which all HUBSAN drones with FPV flight capability are assembled with. The first thing that catches your eye is the impressive size of the remote control and the built-in 10 cm FPV display, which displays a picture from the drone’s camera in real time. By default, the equipment can be powered by 4 AA batteries, which can be immediately attributed to the minuses, since it would be more practical to use a lithium-polymer battery.

Re-equipping the remote for LiPo battery is not a big deal. To do this, you need to purchase a 7.4V 1000mAh 25C LiPo battery with a JST connector and power harnesses with a similar mating connector. The power harnesses must be soldered to the control panel board, having previously disassembled it. Everything you need for the modernization process is sold on well-known Internet trading platforms).

* This is what the remote looks like after removing the battery compartment (it is attached to the plugs in the remote itself). LiPo 7.4V 1000mAh 25C with JST connector is installed in the vacated space. Purchased harnesses with a reciprocal JST connector are soldered to the power contacts on the board. The whole job takes 10–15 minutes.
Appointment of governing bodies
On the remote, in addition to the usual joysticks and trimmers, there are a couple more buttons that are located just above the control sticks. The right one turns video recording on and off. The left one is not active for the Hubsan H111D quadcopter. Switching between normal flight mode and expert mode is done by pressing (for 0.5 seconds) on the right control stick. Headless mode is activated by the same pressing, only on the left control stick. Flips are activated by pressing the left gas stick, but with a holding interval of 1.5 seconds.
A microSD card slot and a miniUSB port are available on the right side of the remote control. The memory card must be inserted into the slot before turning on the remote control! Through the USB port, the user can download the recorded video to a computer.
Menu

The configuration menu on the remote control can be called up by simultaneously long pressing the left control stick (in the “Lower Left Corner” stick position) and the right stick (in the “Center” stick position). The following settings will appear on the screen:
- Recorded Video Playback
- Date and time settings
- Formatting a memory card
- Control setting
- Sensitivity setting
- Manual selection of FPV frequency
- Exit
If the size of the monitor built into the console is not enough, the user can use any other analog FPV monitor operating in the 5.8GHz frequency range.
flight qualities

After flying the Hubsan H111D for the first time indoors, we were surprised how stable this tiny drone is. Despite the lack of an “Altitude Hold” function, the quadcopter is easy to hold at a selected altitude using the throttle stick. Two spending modes are available: “Normal” and “Expert”. Beginners are advised to start with the “Normal” mode. At the very least, this will significantly save on the purchase of rotors.
If the drone flies out of radio range, the motors will immediately stop and the quad will fall. On the one hand, this will not allow him to fly far from the pilot, on the other hand, flying on the street, the pilot risks losing him. Be careful and choose open and free areas for flying!
FPV
The FPV broadcast works fine except for the annoying horizontal stripes that are probably caused by the electrical noise of the brushed motors. When the motors are not working, the picture on the monitor is clear.
If the drone starts to fly in a chaotic direction, it is recommended to calibrate it. Turn on and place the quadric on a horizontal surface. Press and hold the throttle stick to the far right and at the same time move (left to right) the right stick quickly.
Price

The average price for a drone on various Internet marketplaces:
- H111C (X4 Nano Plus) — $38
- H111D (Nano FPV Q4) – $116
Conclusion
Hubsan Q4 H111D $116

pros
- Rugged construction
- Stability and ease of management
- FPV at 5.8GHz analog frequency (no lag)
- Complete FPV Kit
- Two modes for beginners and experts
- The ability to view video recordings on the remote control
- Price
Minuses
- Flight time
- Built-in battery
- Insufficient camera angle
- Horizontal stripes on the monitor screen during flight
- The role of the drone frame is performed by the main board
Summing up, we can say that the Hubsan H111D certainly deserves the attention of the consumer. Design, workmanship, a ready-made FPV kit built on an analog video transmitter and handling that is indicative for this niche will definitely be appreciated by novice pilots. Disappointed by the small viewing angle of the camera. But, if this fact greatly interferes, then the problem can be solved by replacing the standard lens. Despite the built-in FPV monitor, we still recommend flying with FPV goggles, because it is much more interesting and exciting than FPV flying on the monitor. Advanced pilots will confirm.
