Nearer Take a look at the Construct High quality

An exterior HD digicam could be hard-mounted utilizing the offered adapter, however it’s greatest to keep away from including further weight like a unadorned GoPro. Whereas it could work for sluggish and regular indoor photographs, it compromises out of doors agility and velocity. The DJI O3 system already supplies wonderful 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 sort of 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 full weight is round 290 grams.

DJI O3 Setup

Though the CineBot25 helps numerous FPV programs, 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 smooth mounting crucial. I actually like GEPRC’s implementation utilizing silicone balls as it really works exceptionally effectively.

Nevertheless, the digicam cover can simply pop off throughout crashes, and it’s difficult to reattach as a result of how tiny and smooth these silicone balls are. They’re additionally fairly fragile, metallic instruments can simply pierce by them. Whereas GEPRC supplies some instruments to assist with this, it’s a problem remembering to deliver them alongside. Zip ties can safe them however will scale back the effectiveness of the smooth mounting.

Person Pleasant Design

Probably the greatest design features of the CineBot25 is how straightforward it’s to entry the flight controller and DJI O3 USB port. There’s a USB-C port on the rear of the drone, related to the flight controller by way of an extension board.

You possibly can entry the DJI O3’s SD card slot and USB-C port by a cutout within the plastic housing, and when not in use, you possibly can 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 possibly can inform how a lot thought has gone into the design.

Nevertheless, one small problem is that I couldn’t join or flash the ESC by way of 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 might have used a USB-C extension cable like Speedybee did within the Bee35 to keep up compatibility. However it’s not an enormous deal because you don’t usually have to flash your ESC.

Dissembling the drone for restore is simple too.

Flight Efficiency

The CineBot25 S is just among the finest flying 2.5-inch cinewhoops I’ve examined—very secure, 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 obtained round 5 to six minutes of flight time (a mixture of aggressive flying and cruising), which may 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, supplies crisp FPV footage with none jello.

One other problem I observed is with the video sign and vary – the bitrate drops noticeably extra rapidly as I fly additional away, presumably because of the UFL extension cables for the O3 antenna. One resolution is to keep away from utilizing these extension cables and go for an extended antenna, such because the Flyfish Osprey: https://oscarliang.com/fpv-antenna-swr/#FlyfishRC-Osprey-Twin-band-140mm. You merely want to chop the plastic tube shorter.

How you can 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 offered, so that you’ll want to make use of your creativeness. I need to admit it wasn’t straightforward in any respect as I spent over an hour looking for one of the best ways to mount the O3. Ultimately I made a decision to not use the offered heatsink and simply mounted the O3 straight contained in the plastic housing.

Additionally, in contrast to BetaFPV’s cinewhoops, GEPRC doesn’t present any cable for the O3, however you should utilize the unique cable, so it’s not an enormous problem should you nonetheless have it. Additionally there’s no screws offered for mounting the digicam within the cover – you will have M2 3mm.

Lastly, ensure to tape the UFL extension to keep away from electrical shorts! It they touches the uncovered battery solder pads might fry your O3!

Binding Receiver

Right here I encountered one other problem – 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 achieved by going into WiFi mode (by plugging in battery and wait 60 seconds) and checking on the Net 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 Net 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’ll find the unique CLI diff right here: https://intofpv.com/t-cli-dump-for-the-geprc-cinebot25-s.

  • In Preset tab, apply ExpressLRS Preset primarily based on the packet fee of your alternative.
  • In PID Tuning tab, set your individual charges.
  • In Modes tab, assign swap for arming.
  • In OSD tab, configure OSD parts. Though HD was chosen, the canvas was caught in analog dimension. 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 among the finest design available on the market, and the flight efficiency is superb! Whereas there are a couple of hurdles to beat throughout setup, these are usually not deal breakers. Should you’re searching for a 2.5-inch cinewhoop for the DJI O3 system, that is the one I’d advocate proper now.

Nevertheless, this drone isn’t designed for sub-250 grams in thoughts. You can in all probability push it below 250 grams by going analog or utilizing a smaller battery, however you’d be higher off with a 2-inch quad as an alternative (try the Pavo20). I additionally don’t advocate 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 presents 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.
