Flight Controller
- Model:STABLE PRO F7 35A
- MCU: STM32F722RET6
- IMU: 2x ICM20689(SPI)
- OSD: BetaFlight OSD w/ AT7456E chip
- Firmware target: EXF722DUAL
- Integrated LC Filter
- Size: 26x26mm board, 20mm mounting holes (M2)
GEPRC CinePro 4K FC is soft mounted providing a clean operating environment for gyro, reducing the noise coming from motor vibrations.
It is a good idea to configure the OSD to show the core temp, since it gets pretty hot if the quad is not flying.
ESC BLheli_32 2-6S 4in1
GEPRC CinePro 4K is equipped with a 4in1 ESCs system running BLheli 32 bits. These are the details:
- MCU:STM32F051
- Constant: 35Amps
- Burst: 45Amps
- Mounting Holes: 20*20mm,M2
- Supports Dshot1200, Proshot, Oneshot, Multishot
- Current meter: Yes
- Target: GEPRC-BL32-4IN1
VTX
As reported down below, GEPRC CinePro 4K VTX has a maximum power output of 500mW which is very nice, since most of this kind of quads have a max of 200mw:
- Input voltage: 5V
- Frequency: 5.8 GHz
- Channel: 48
- Power transmission: 0mW(Pit mode) / 25mW / 100mW / 200mW / 400mW/ 500mW
- Connector type: MMCX Connector
- Traditional button
- IRC Tramp protocol
It has smart audio, so it is possible to change VTX power output using the transmitter to modify the values on the OSD. It comes with a linear antenna rather than a circularly polarized one.
Caddx Tarsier Cameras System
Probably the most important feature is given by the Caddx Tarsier: this is a dual camera system, where the bottom camera is a normal FPV camera, while the top one is an HD camera that records up to 4k@30FPS. Having two different cameras ensures low latency with respect to a single split camera system recording during FPV flights: this is really important especially when flying indoor where spaces are limited and it is easy to crash into objects. The manufacturer reports that the 1200TVL FPV camera has a latency within 10ms.
This system records also audio and the quality is very good.
A 7075 aviation aluminum bay protects the dual camera system and this is also important because, differently from TPU, it ensures stable video with no jello effect.
The slot for the SD card is a little bit difficult to reach since it is behind the front left motor protector. A good SD card for this model is the SanDisk Extreme PRO V30 U3 A2 . In order to have the SD card to work correctly, it is important to format the SD card first through the computer and then insert it into the quad and format again using the app.
Through the app it is possible to connect to the quad through Wi-Fi and change the recording options like format, resolution (this can be done also through the button on the quad, but it is not very easy to understand the current configuration through led color) and so on.
To activate the Wi-Fi there is a button on the right side: after a long press, a flashing green light underneath indicates the Wi-Fi hotspot is active. Then, it is just a matter of connecting to the Wi-Fi through the smartphone (the SSID is something like CADDX_xxxxxx and the default password is given by numbers from 1 to 8). From the app it is also possible to take picture and start/stop video recording.
These are available resolutions:
- 4K@30FPS;
- 2.7K@60FPS;
- 1440P@60FPS;
- 1440P@30FPS;
- 1080P@90FPS;
- 1080P@60FPS;
- 1080P@30FPS;
- 720P@120FPS;
- 720P@60FPS;
- 720P@30FPS.
Motors and Propellers
Motors are GEP-GR1105 5000KV: the manufacturer recommends to use 4S LiPo for best performance.
GEPRC CinePro 4K package contains two different types of props: just use the ones already mounted, i.e. the EMAX AVAN 2 inch 4-blade; it is always good to buy some EMAX AVAN 2 inch 4-blade props for spares.
Battery
Battery is not included like for almost every BNF/PNP quadcopter. Two possible choices are the following, one is 3S, the other is 4S:
- Gaoneng GNB 11.1V 650mAh 80C/160C 3S XT30 Plug Lipo Battery
- Gaoneng GNB 14.8V 650mAh 80C/160C 4S XT30 Plug Lipo Battery
The quad mounts an anti-slip mat and a velcro strap for the LiPo battery.
On the back there are a beeper and a low ESR capacitor to filter noise coming through the system. On the rear, there are also some taillights for night view and lighting effects.
Conclusions
GEPRC CinePro 4K is a FPV cinematic quadcopter that is made for pilots looking for a small drone to record stable video footage in high resolution and even 4K, both indoor and outdoor. Since the cost difference between the Basic and Advanced version is pretty small, it is for sure convenient to choose the second one.
