After the wide success of the H8C, a great brushed miniquadcopter copying Phantom/CX-20 design and after the relative fiasco of the JJRC H9D (a fake 5.8G FPV in practice), JJRC here is introducing here the “real” FPV version of the H8C: same quadcopter chassis + a real 5.8G FPV system-HD camera combo. This model comes after the WLtoys V686G FPV model and probably uses the same video combo.
+ 1 x JJRC H8D (with a 2S 500mAh LiPo)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x 4″3 LCD monitor including a 5.8G VRX
+ 1 x USB microSC reader
+ 1 x 2Gb microSD
+ 4 x Prop guard
+ 1 x 5.8G dipole antenna
+ 1 x charger for the quadricopter LiPo
+ 1 x USB charger cable for the Monitor Lipo
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Instruction manual (English/Chinese)
As said previously, the H8D uses the same quadcopter chassis than the H8C. you can find the full review here: http://www.rcgroups.com/forums/showthread.php?t=2276138. It means, that you can only order the FPV combo to adapt to your H8C if you already own a 5.8G ground station.

With the combo attached beneath
The lens orientation can be ajusted, it’s a good point
In comparaison with the WLtoys V686G and the JJRC H8C
Strictly idendical in external point of view with the H8C.
148g without prop guards…. so close to 4g more heavier than the H8C.
The lipo is the same than the H8C, a 2S model using a non-JST connector
The H8D still uses a 2S system and unfortunatly motors are strictly indentical to the H8C. They are known to have short duration life due to the extra stress on them with the 2S voltage. I strongly advice:
– to check before each flying session if all all props are spinning freely by hand
– to install some ball-bearings (MR74 format) to replace default bronze bushings
– to add time to time a drop of sillicone oïl into bearings only
Only the transmitter chassis changed versus the H8C
Now it uses the same introduced with the H12C : a large model easy to grab for large hands and a wheel to fine-tune the speed rate. It’s a good RTF model
– LCD monitor
The LCD is a small 4″.3 monitor identical to the V686G model
On top right, you can screw via the SMA connector any 5.8G antenna
It’s shipped with a linear model
The screen is extremely brillant
more the brightness setting can’t be tuned…. so even with the sun shade, it’s very hard to see the “live” transmission outdoors. Definitively a bad point Another concern is about LCD mounting into the radio. The LCD is clipsed into a TX’s hole but can rotate freely over an x-axis. By consequence if your are holding the radio vertically, the LCD can fall on sticks control during flight… Not ideal and potentially dangerous
Referenced V1.6 versus V1.5 for the V686G.
The video is transmitted in NTSC format @5645Mhz (Freq 4 of Boscam band), so exactly the same frequency as for the V686G. This frequency can’t be ajusted (except by modding both VTX & VRX parts). As for the V686G, video files are automatically splitted every 3mins.
Bad news, the lens mount is smaller than for the V686G. It means you can’t scews the “BG” M7 lens as for the V686G
Direct comparaison with the 808#16 lens D
Unfortunatly, when you install the 808#16 lens D, the color are absolutly not respected and the video is reversed. If you still want to install this lens, you will need to mod the camera casing to flip the camera FC
The attached linear antenna.
Well the H8D is a as good flyer as the H8C agile, sporty in 100% rate and relatively wind resistant (vs the V686G at least). The FPV transmission is excellent (~100m easily) and HD camera part offers very good quality and jellofree videos (as good as the V686G). The control range is also good (around 100m out of the box) but not as good as for the V686G IMHO. You can probably improve it by positioning antenna vertically Inside the H8D canopy. Any two main concerns have to be raised : 1) the 2S system strongly requiers some ball-bearings installation to improve motor’s durability (even if it’s not 100% sure) and 2) actually any wide lens 100% working is available. The real question is : V686G or this one ? Except if you own already a H8C, want a more sporty quad, I advice to go more on the WLtoys V686G model because of the last two points.
FPV session recorded with my GS922 set on 5645Mhz/NTSC
I am really suprized by the quality of the FPV part. I measured input voltage on connector : 5V and 3.40V respectively… so more than the 4V for the WLtoys V686G
+ Very good flyer, stable for beginner and sporty in 100% mode
+ Nice design
+ Robust and durable
+ Jellofree plateform out of the box
+ Good control range (~ 100m)
+ Good TX radio
+ Orientable lens
+ Efficient video transmission (> 100m, NTSC format @5645Mhz)
+ DeviationTX compatible
– No ball-bearings
– Same 2S motors with shorter life (need absolutly ball-bearings installation to decrease extra friction)
– Narrow FOV with the default lens
– Pseudo “homing/RTH” with more and more random effect when engaged late in flight
– No 100% compatible with 808#16 lens D
– Shorter range than WLtoys V686G
– Brillant screen (very hard to use outdoors even with the presence of the sun shade)
– Wide M7 lens can’t be installed and 808#16 lens not 100% compatible. Need camera casing modifications in any case

This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thanks them for this attitude.
You can find it actually for 121 USD at
