A new first entry FPV micro machine “à la” Hubsan H107D+ is introduced by JJRC with the JJRC H32GH. A compact machine including a 720p camera and broadcasting the FPV signal in the 5.8G band. Like the D+ from Hubsan, the altitulde hold feature is included. If for beginners it means a more easy machine to fly outdoors, for indoors FPV it’s not always a good idea.
+ 1 x JJRC H32GH (with a 1S 600mAh LiPo with microLOSI connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 2 x USB charging cable
+ 4 x Spare props (2 CW, 2 CCW)
+ 4 x Prop guards
+ 1 x Landing skid
+ 1 x Screwdriver
+ 1 x Prop remover wrench
+ 1 x Instruction manual (English/Chinese)
The chasssis is full plastic based and since the total weight is relatively small, the JJRC should survice to most type of crash. The general look represents a kind of a shrinked JJRC H12 model.
The right side welcomes a small tiny power switch
The battery bay is filled completly by the provided LiPo
The linear antenna is clipsed beneath. In this position, the FPV signal will be stronger for vertical flights but weaker if you fly aligned with the transmitter in the horizontal plan.
The DVR microSD slot can noticed on the right. Good news, a MIC is attached and sound is recorded on the AVI files.
for a total of 58.2g with the battery inserted
With the landing ger and prop guard installed, the machine reaches close to 62g
Motors are classic 8520 brushed motors (8.5mmx20mm)
They are strong enough and offert a good lift in practice under the control of the altitude hold
A 500mAh 1 cell model ending with microLOSI connector. No discharge rates mentionned.
A 47mmx20mmx9mm model
The video part is a 3-in-1 board with a 720p camera, builtin DVR and builtin 5.8G FPV VTX. No possibility to fix the frequency locked to the E4=5645Mhz
The signal is broadcasted in NTSC format. The latency is small even when the recording is turning on. No frame rate observed when recording 720p files
A M6 lens thread unfortunatly is here
It means, no easy way to find a lens with a larger FOV… AFAIK, no model available in M6 format … It’s a real pity, they don’t use a lens sensor in M7 format.
More the light sensitivity of the sensor is relatively poor (> 1 Lux IMHO) and in poor light conditions, the machine will be almost blind.
Here is a small raw video recorded by the builtin DVR
The general quality is good, jellofree ….
The small 4″3 FPV monitor have a brilland screen and the brighness level is relatively poor. In strong day lights, it will be hard to see the FPV session despite the presence of a sunshade.
The “No screen” text the signal is absent of lost…. instead of desired the white snow
It means the FPV monitor is not really FPV friendly
The image resolution is QVGA so far from the original NTSC broadcasted FPV signal.
The black square is the foam protecting the barometer chip.
Installed on front a XN297L, the new RF revision including the 250kbits datarate. The radio protocol is more time a new one but is working @250bit/s… So in practice a better range.
The ARM core is installed nearby and finally installed and protected by a foam structure, the barometer for the altitulde hold stabilization.
The classic deluxe chassis of JJRC model. This model is cool in the sens you can turn it into mode 2 (left throttle) or mode 1 (right throttle)
Two shoulder buttons: the left one turn on/off lights while the right is assumed to perform flips. 4 pannel buttons and a large wheel can be found too. The lower left button permits to turn on/off motor engine, a kind of autotake off, auto landing features. Be aware, when you take off, the machine climbs immediatly 1m higher. The right lower button turn on/off headless button. You can apply precise rates via the large central wheel. From beginner rate limited to 50% up to 100% for the most sporty mode. To calibrate the machine push both sticks in lower left position.
UNBOXING, ANALYSIS AND DEMO FLIGHT
For outdoors and relatively windfree conditions, the JJRC performs well and super smooth. The FPV signal is strong, no big breakup within 50m. The rates even set to 100% won’t allow the H32GH to be super fast. Surprizing the altitude seems limited to 5m. Both FPV and 720p videos are jellofree. Color are vivid but light sensitivity not great. Flight time are average of 4m before to see the first LVC warning when recording is turned on. I deeply regret the narrow FOV associated with the actual pinhole lens and the downtilt orientation not very compatible with real FPV practice. The altitulde hold for indoors flight can present some strange and quick altitude variation especially after a turn … For precise indoors flights, it’s not a good news. It would have been great to disable this feature…
The JJRC H32GH is a microFPV machine more adapted for FPV beginners in outdoors openfield conditions. The FPV part is more usefull to monitor the scene that you are currently focusing than a real FPV racing machine. Both control and FPV ranges are largely enough to “mine” your garden with the H32GH. The FPV signal can cross several walls without difficulties. The 720p videos have a good quality comparatively for the size of the machine, it’s a good positive point. The limited FOV like for 99% of toys is the limited factor and unfortunatly no real trick to overcome this limitation. The Hubsan H107D+ is superior on this point but the altitulde hold of the Hubsan is super annoying in another hand.
