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.
+ 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)
The H111D is also a 60mm quadcopter like the H111C model (right) so a little more larger than classic 45mm nanoquadcopter.
The main structure is the same, an H design with arms
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.
For the H111D, you have tiny switch versus a press button for the C model.
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.
18.5g for a full FPV machine, probably the lightest RTF model available in 5.8G band.
Classic 6mmx12mm coreless motors Short wires directly soldered on motor’s hub part.
A 180mah model directly connected to the main PCB
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)
The camera sensor with a 170degrees lens installed
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.
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.
Notice also than all chips are covered with liquid electronic tape, a good waterproof protection.
All antennas (2.4G & 5.8G) are patch’ones … it means a little bit more directional too.
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.
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
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
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.
A raw example after rebuilding the indexes

Only 0.5g added
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 🙁 …. 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.
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 🙂 )
+ 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

+ Not expensive
– 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
