I’ve examined many cinewhoops prior to now few years, and the GEPRC CineBot25 is probably my present favourite 2.5″ cinewhoop. A lot thought has gone into its design, and the eye to element is just superb. Whereas it’s not good and has a number of annoying points, as you’ll uncover on this evaluate, these quirks don’t detract from its spectacular efficiency.

Nearer Take a look at the Construct High quality
The GEPRC CineBot25 S stands out with a strong, modern design. The digicam, motor, and flight controller are mounted on the highest plate, which is constructed from smooth-layered carbon fiber, providing a light-weight but sturdy really feel.
Beneath the highest plate is a detachable plastic housing for the VTX and receiver. The digital parts are nicely protected, however the enclosed design would possibly compromise cooling in sizzling environments.
The FPV digicam is mounted inside a devoted soft-mounted cover that limits excessive digicam angles however gives enough safety.
An exterior HD digicam might be hard-mounted utilizing the supplied adapter, nevertheless it’s finest to keep away from including additional weight like a unadorned GoPro. Whereas it might work for gradual and regular indoor photographs, it compromises outside agility and pace. The DJI O3 system already gives glorious picture high quality anyway.
Two battery straps of various lengths are included: an extended one for 4S 750mAh and 850mAh batteries, and a shorter one for smaller 4S 650mAh batteries. The drone weighs round 153 grams with out the battery, digicam, and VTX, which is nearly 10 grams heavier than the BetaFPV Pavo25 V2. Nevertheless, this added weight is comprehensible given the additional plastic used for cover.
With the DJI O3 system put in and a 4S 850mAh LiPo, the whole weight is round 290 grams.
Listed here are some facet by facet comparisons to the BetaFPV Pavo25 V2:
DJI O3 Setup
Though the CineBot25 helps varied FPV techniques, together with analog and Runcam Hyperlink/Wasp, the soft-mounted digicam platform is a transparent indication that it’s particularly designed for the DJI O3 system. Different FPV cameras aren’t as prone to jello and vibration because the O3, making extra comfortable mounting vital. I actually like GEPRC’s implementation utilizing silicone balls as it really works exceptionally nicely.
Nevertheless, the digicam cover can simply pop off throughout crashes, and it’s difficult to reattach resulting from how tiny and comfortable these silicone balls are. They’re additionally fairly fragile, metallic instruments can simply pierce via them. Whereas GEPRC gives some instruments to assist with this, it’s a trouble remembering to deliver them alongside. Zip ties can safe them however will cut back the effectiveness of the comfortable mounting.
Person Pleasant Design
Among the best design features of the CineBot25 is how simple it’s to entry the flight controller and DJI O3 USB port. There’s a USB-C port on the rear of the drone, linked to the flight controller through an extension board.
You’ll be able to entry the DJI O3’s SD card slot and USB-C port via a cutout within the plastic housing, and when not in use, you may put the rubber cowl again on to guard it from filth and water.
There’s no have to disassemble the drone or use an adapter to entry these USB ports, making it extremely handy. You’ll be able to inform how a lot thought has gone into the design.
Nevertheless, one small difficulty is that I couldn’t join or flash the ESC through the USB port on the FC extension board. I had to make use of the precise USB port on the FC, which requires disassembling the drone. They may have used a USB-C extension cable like Speedybee did within the Bee35 to take care of compatibility. But it surely’s not an enormous deal because you don’t sometimes have to flash your ESC.
Dissembling the drone for restore is straightforward too.
Right here’s a detailed up shot of the flight controller.
Flight Efficiency
The CineBot25 S is just top-of-the-line flying 2.5-inch cinewhoops I’ve examined—very steady, well-tuned, and with loads of energy for freestyle.
It’s additionally very environment friendly. I examined mine with LAVA 4S 850mAh LiHV batteries from BetaFPV and bought round 5 to six minutes of flight time (a mixture of aggressive flying and cruising), which could be very spectacular. I examined this battery right here, it’s fairly good: https://oscarliang.com/whoop-toothpick-lipo-battery/#4S-LiPOLiHV
The DJI O3 VTX system, paired with a soft-mounted digicam, gives crisp FPV footage with none jello.
The way to Setup
Though initially I used to be impressed by the CineBot25’s design, the setup course of took a bit extra time and effort than anticipated.
O3 Set up
Very first thing is to put in the DJI O3 system contained in the plastic housing. Sadly, there’s no instruction supplied, so that you’ll want to make use of your creativeness. I need to admit it wasn’t simple in any respect as I spent over virtually an hour looking for one of the simplest ways to mount the O3. Ultimately I made a decision to not use the supplied heatsink and simply mounted the O3 immediately contained in the plastic housing.
Additionally, in contrast to BetaFPV’s cinewhoops, GEPRC doesn’t present any cable for the O3, however you should use the unique cable, so it’s not an enormous difficulty when you nonetheless have it. Additionally there’s no screws supplied for mounting the digicam within the cover – you will have M2 3mm.
Lastly, be sure to tape the UFL extension to keep away from electrical shorts! It they touches the uncovered battery solder pads may fry your O3!
Binding Receiver
Right here I encountered one other difficulty – the receiver doesn’t get energy from the USB port, you should plug in a battery.
I used to be going to flash the most recent ExpressLRS firmware to the receiver together with my binding phrase, so I wanted to search out out what goal it makes use of. That was completed by going into WiFi mode (by plugging in battery and wait 60 seconds) and checking on the Internet UI .
Receiver goal is: Generic ESP8285 PA 2.4Ghz RX, it comes with 3.3.1 firmware.
Nevertheless, I couldn’t discover this goal within the newest ExpressLRS Configurator, so I didn’t replace the firmware however set the binding phrase within the Internet UI.
Betaflight Configuration
Establishing Betaflight for maiden flight was easy.
The CineBot25 comes with Betaflight 4.5.0. The flight controller goal is TAKERG4AIO. You will discover the unique CLI diff right here: https://intofpv.com/t-cli-dump-for-the-geprc-cinebot25-s.
- In Preset tab, apply ExpressLRS Preset based mostly on the packet charge of your selection.
- In PID Tuning tab, set your personal charges.
- In Modes tab, assign swap for arming.
- In OSD tab, configure OSD parts. Though HD was chosen, the canvas was caught in analog measurement. I needed to de-select and choose HD once more to get the bigger HD OSD canvas.
Conclusion
I’m blown away by the GEPRC CineBot25 S—it has top-of-the-line design available on the market, and the flight efficiency is great! Whereas there are a number of hurdles to beat throughout setup, these aren’t deal breakers. In the event you’re in search of a 2.5-inch cinewhoop for the DJI O3 system, that is the one I’d suggest proper now.

Get some spare propellers:
Nevertheless, this drone isn’t designed for sub-250 grams in thoughts. You can most likely push it beneath 250 grams by going analog or utilizing a smaller battery, however you’d be higher off with a 2-inch quad as a substitute (try the Pavo20). I additionally don’t suggest utilizing a GoPro on the CineBot25; it kills its flight efficiency and flight time. If you wish to use a GoPro, go for a 3-inch or 3.5-inch quad.
For cinematic FPV flying and dynamic photographs utilizing the O3, the CineBot25 S gives incredible design and efficiency at a good worth level. With its highly effective motors and DJI O3 compatibility, it stands out as a powerful contender within the cinewhoop market.
