TEST: HUBSAN H111D, the lightest 5.8G FPV quadcopter ?

null

INTRODUCTION

Problably with the Hubsan H111D, we have here the smallest & lightest RFF 5.8G FPV machine. A full solution under 19g !!!! ideal for beginner and absolutly no dangerous for others. Let’s discover the bundle.

BOX CONTENT

null

+ 1 x Hubsan H111D (with a 1S 180mAh LiPo directly fixed)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB charging cable
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Instruction manual (English)

OVERVIEW

The H111D is also a 60mm quadcopter like the H111C model (right) so a little more larger than classic 45mm nanoquadcopter.

null

The main structure is the same, an H design with arms

-SIDE VIEW

-REAR VIEW
null

-UPPER VIEW
As the H111C, arms are based with these two thin plate tube IMHO potentially breakable if the machine fall on very hard surface. I don’t raise such caution if you fly more outdoors into the grass.I regret the choice of the green color only in this case. I would prefer orange color.

null

-BOTTOM VIEW
For the H111D, you have tiny switch versus a press button for the C model.

null

The battery connector is the same than the H111C model. In practice easy to connect and disconnect with no possibilitu to be wrong.
In practice, I advise to cut the plug from the charger and solder a male JST connector. You will be able to use a normal charger. It will protect more the LiPo versus time.

-WEIGHT
18.5g for a full FPV machine, probably the lightest RTF model available in 5.8G band.

null

Motors

Classic 6mmx12mm coreless motors Short wires directly soldered on motor’s hub part.

LiPo

A 180mah model directly connected to the main PCB

null

null

Camera module

If the lens thread of the D version seems smaller, it’s not the case in practice. It’s a M7 (6.85mm thread) and it’s an exellent news if you want to install a lens with a wider FOV (seel the last part of my video)

null

The camera sensor with a 170degrees lens installed

null

Disassembling

Please find instruction how at least to remove the lower canopy part in the main video (last part). You will need to remove first the two front screws than push vertically the plastic pad Inside the guide with a thin screwdriver.

null

null

The RTC6705 for the 5.8G FPV part is installed front. The RFchip is the A7105 and the protocol is compatible with the H107x serie. A good news since this protocol is integrated in DeviationTX.

null

Notice also than all chips are covered with liquid electronic tape, a good waterproof protection.

null

All antennas (2.4G & 5.8G) are patch’ones … it means a little bit more directional too.

null

Transmitter

The classic radio-FPV chassis from Hubsan with a builtin 4.3″ FPV monitor. No sunshade are provided but the screen have a suffisant brightness to handle daylights without too much problem.

null

Control sticks are the same than the H107D+ model. If you click briefly on the left sitck your turn on/off the headless mode (blue front LEDs will flash). If you long press on it, you will perform a 360degrees flips. If you briefly press on the right stick, you cycle between normal & the expert mode and if you long press on it, you enter into the menu. To record your FPV session, press the right balck square button.
Finally to calibrate the gyros, push the left stick in lower right position than move left and right quick the right stick.

The 4.3″ is visible even with strong daylights

null

The left side welcomes two 3.5mm jack connectors. Only the bottom one can export the AV signal for a goggles/monitor for example

The right side have a miniUSB connector for a TX firmware upgrate and microSD card slot. No microSD card is provided in the bundle

null

When you record a file, a lost of small files are created in the root folder then the final result file can be found in the VIDEO folder. Notice you can’t read the file directly, indexes are corrupted. I use the free software “WinX Video Converter” to rebuild everything. The file are saved without sound in 720×240 resolution compressing the vertical axis.

UNBOXING & TESTING

The H111D is stable with relatively slow rates even in expert mode. Definitively less sporty than the H111C version. Probably, Hubsan want to offer the most stable videos are possible. The FPV range is pretty good. You can cross 2-3 walls very easyly and in LOS the FPV range reach 50m without problem. No problem too for the control range too. Flight times are also good, approximatively between 5-6min…. not bad at all. The default FOV is very limited !!!! around 70degrees … For me it’s not compatible with FPV !!! (or at 0.01m/s !!!! for beeing safe). Definively the M7 lens mod is a must to do. In term of lens thread, this M7 models fit well: http://www.banggood.com/M7-1_8mm-Wide-Angle-Lens-For-Mini-Camera-p-962825.html.
For this model: http://www.banggood.com/M5_5-15_8-1_84mm-2MP-Wide-angel-Lens-for-16-17-OV2722-Sensor-Syma-X5C-Hubsan-X4-H107D-H107C-p-1055858.html, the thread is loo long to set correctly the focus …. Other models (the 808#16 lens D) can be probably installed too. Unfortunatly I broke my camera sensor module at the end of the lens focusing tuning πŸ™ …. So be aware, the lens mod is not super easy. You need absolutply to remove gently the residue of hot glue first and gently unscrew the lens without damaging the ribbon cable. I will update as soon as I will receive a new module.

CONCLUSIONS

Interesting model from Hubsan who offers a nice & stable FPV machine with both FPV and control range. With relatively slow rates; this machine targets beginners FPV pilots. The real drawback for me is the absence of the wider FOV…. The actual one is for me almost incompatible with proximity flights. It’s a pity because all other elements are homogeneous. Luckely the M7 lens mod can be done but be aware it’s a little bit tricky (I even failed it by myself πŸ™‚ )

PROS

+ Stable machine
+ Great beginner indoor FPV trainer
+ Good FPV range (~50m w/o problem)
+ 5-6min of flight time
+ Builtin DVR to record FPV flight session
+ 18.5g machine
+ Same H10X RF protocol
+ DeviationTX comptible
+ M7 lens mod possible
+ PCB covered with liquid electronic tape (waterproof protection)
+ Not expensive

CONS

– Black screen with FPV signal is lost
– Limited FOV (~70 degrees)
– Rates a little bit slow, especially yaw rate
– FPV recorded file in 720×240 and need indexes to be rebuild
– No microSD card provided
– Green color only (can be lost easily into grass)

    Hello

    Since you have quite a bit of experience may I ask you which micro or mini fpv quad you can truely recommend?

    I looking for a small quad with is good smooth to fly, for beginners and intermediate, has good picture with no lines or disturbances in it, durable and at least 30m range. I like to fly around tight spaces like at home or in the garden. For the whole package I like to stay below 150euro.

    Do you think it is possible to take the screen out of the TV from the hubsan, extend the wire and put it into a google cardboard or a cheap replacement housing for some goggles? You said the display is good so I could safe the money and trial and error to get some matching goggles for this quad. Ever done such a mod?

    A top 5 quad chart of different categories (micro mini fpv area shot racer etc) would be something I like to see on your page. Just a chart to keep overview. Or like your top 5 for fun flying, outdoor, acrobatics, fpv….

    Thank you
    Be well

    Thanks a lot for your reply and recommendations. The qx90 seems to come close to what I am looking for. I only don’t like the props to be in the picture. Can’t wait you to review the qx100 which hopefully has no props in the field of sight.

    Do you have a link to a post which explains how to match the right tx and goggles with a quad? I get super confused when looking through so many products with all these different names of protocols frequencies brands etc.. What can I combine with what? What matches best?

    Do I have to care if the antennas of the tx, goggles and quad differ as well? Sorry for my many questions but I have little to no experience (I read a lot but still I am not certain) and you seem to know a great deal about these things.

    Well to be suggestive is unavoidable with whatever you write. Even your unbiased reviews have impact on the choice people make.

    Thanks a lot!

      As soon you have a 32CH/40CH VRX, everything will match fine with the VTX don’t worry for that. For FPV racing, as soon as your have cloverleaf, you can expect a good reception in proximity flights.
      With cloverleaf antennas, you have to check if both have the same pololrization: RHCP or LHCP. In practice, it means, the antenna steep sens must coincid.

    Hello, is it possible to install normal 1s lipo?
