GEPRC CinePro 4K Cinewhoop: review, complete setup, flight footage

September 07, 2019 ⌛⌛⌛⌛⌛ 21 min read

It seemed to me that on the cinewhoop front, there have been a lot of advancements lately, in particular, models such as the GEPRC CinePro that carry a Caddx Tarsier 4K camera with 2 separate sensors, definitely catch the eye and excite me. In this review and setup guide, we’re gonna have a look at the advanced version of this drone with the FrSky XM+ receiver (BNF).

One of the quads I’ve flown the most during 2019 is the Mobula7 HD (which I love flying! - just look at the number of videos in that playlist on my channel). And while in general I prefer and started with 5-inch drones, there’s something super cool about being able to whip this little quad out and just fly it in a park without disturbing other people. My only desire with the Mobula7 HD was to just have a full range receiver, as the built-in SPI based receiver only gets you about 100 meters or so. This was the other main reason why I was very curious to test the GEPRC CinePro as it comes with a full range receiver.

Whether you are a cinewhoop veteran, or just considering getting into cinewhooping, I think you will find this post useful. Let’s get to it!

📦 Unboxing

When I think of the GEPRC CinePro 4K cinewhoop unboxing experience, I think of two things: minimalistic and high-quality gear.

GEPRC CinePro box

Once you open the box, you are immediately presented the quad, which looks like a piece of art, but more on that in a sec.

The quad is wrapped in this protective film.

… some stickers, a couple of velcro straps, antenna tubes and an extra set of spare props. Those props are Dalprop Cyclone Q2035C, quad blade high-quality propellers. The props that the quad comes with already installed are also high quality - Emax Avan 2 inch. Both sets offer very different flight experiences, as we’ll see a bit later.

GEPRC CinePro spare props, stickers and velcro straps

The components are very high quality, the quad is gorgeous and the assembly work - top notch. Shiny solder joints, well-placed antennas and shrink wrap, really superb build quality, which is great, given that the GEPRC CinePro 4K comes with a price tag of about $270.

📝 Specifications

Sturdy high-quality carbon fiber frame. Dead cat shape and 115mm motor to motor diagonal distance, versus 69mm between the front and the back motor. This makes sure you never get your props in the shot.

Thick plastic prop guards, not flimsy at all. The props are secured with 2 screws each. Also, note that this quad comes configured in props out mode, so pay attention to that if you are swapping props.

I fly almost all my quads in what I believe also to be more common props in setup.

As you can tell the camera tilt is not at all aggressive which is somewhat expected when we are talking about a cinewhoop, as the goal is probably not so much to rip packs like crazy, but rather capture slower, more cinematic footage.

Plenty of space on top for mounting a battery, as well as 2 slots for guiding the velcro straps through.

The motors are the GEP-GR1105 5000KV and the recommended battery is a 4S lipo for those.

⚙ Setup

In terms of setup, here’s what we need to do to get up and running: 🔗 Bind the receiver to the radio, 📇 Insert an SD card, ⛓ Install the velcro straps, 📡 Configure RSSI, channel mapping and modes in Betaflight and 🎥 Configure the Caddx Tarsier 4K camera via the app.

🔗 Bind the receiver to the radio

The process was the same as usual (I use FrSky XM+ on almost all of my models). Put your radio in bind mode, press and hold the bind button on the receiver, while plugging in a battery. An extra set of hands helps a great deal with this, but you can also do just fine on your own, although a bit tricky. The receiver will then bind. After that turn off the binding function on your radio, unplug the quad and finally power it on again.

If all went well, after the final power cycle, the XM+ will have its led in solid green to indicate that it’s now linked to your transmitter.

📇 Insert an SD card

Fairly straight forward - the only thing is, the ducts are a bit in the way, but luckily just pushing them down slightly allows for just enough space to insert the SD card in its slot.

⛓ Install the velcro straps

Installing the battery straps is also pretty straight forward. Depending on what batteries you’re using you might be able to get away with just one of them, but I had to use both. I set up mine by guiding them through the designated slots on the top frame.

📡 Configure RSSI, channel mapping and modes in Betaflight

First thing you’ll notice is that the micro USB port is somewhat tricky to access. I’m happy to report that it is still accessible with a smaller, slimmer cable. I had this cable laying around and was able to use it to configure the CinePro. Alternatively, you could use an L type right angle micro USB adapter. Worst case scenario you might have to unscrew the motor screws to take off the duct and plug in your USB cable.

My GEPRC CinePro drone didn’t come with RSSI configured correctly for XM+ receivers, so definitely check yours and set it up accordingly. That’s a quick 3 step process:

On the Configuration tab locate RSSI_ADC and make sure it’s turned off.

On the Receiver tab set RSSI Channel to AUX12.

Finally, in the OSD tab enable RSSI value to allow displaying it in the OSD.

Channel mapping

My GEPRC CinePro came with its channel map configured to AETR and I’m always using TAER channel mapping so I had to change it. If you don’t want things going wrong or best case scenario driving out to the field just to find out you can’t arm your quad because of your channel mapping (or having to change it in your radio), make sure to configure this beforehand here.

GEPRC CinePro Receiver tab in Betaflight

In my case, after changing to TAER1234 all the channels were responding correctly.

Modes and switches

Finally, let’s set up an arm switch and some flight modes on a switch. Jump over to the Modes tab in Betaflight.

I have this convention where my arming switch is Channel 5 on AUX 1 and this is the right-hand side 2 position switch on my radio. Then my modes are on the 3 position switch next to it and those correspond to Channel 6 or AUX 2 in Betaflight.

For a Taranis radio you need to add your switch sources to Channel 5 and Channel 6 in the radio mixer screen, then assign AUX 1 to ARM and AUX 2 to some modes. I have Angle and Horizon mode on that switch, but by default in its starting position is in Acro as that’s what I use to fly.

That’s it in terms of setup. Here are all the other Betaflight settings, which are pretty much the defaults and left as is.

🎥 Configure the Caddx Tarsier 4K camera via the app

The last thing we have to do before we can go out and fly is to set up the Caddx Tarsier camera. Unfortunately, even though this is an outstanding camera in terms of both FPV feed and recorded footage, the user experience of the setup via the app is suboptimal, to say the least.

First thing you want to do is to go download the CaddxFPV from Google Play (or the Apple AppStore).

Also, something to note is that if you are going to be providing power to the whole quad with a lipo, you probably wanna be quick as the VTX gets pretty toasty pretty quick (unlike while you’re flying when it can cool off).

The camera has 2 buttons on the side. One for powering it on and off and the other one for initiating the WiFi connection.

GEPRC CinePro camera buttons

Long press the WiFi button for 8 seconds until you see blinking green light from the camera board.

Open the CaddxFPV app and tap Connect camera. That’s gonna take you to your wifi settings where you need to tap on the CADDX network.

The default password is 12345678 (you can change that in the camera settings later).

Going back to the app and tapping the Access camera button (or something similar) will finally present you the first screen of camera options.

If you are getting stuck and are unable to access the camera, try stopping your 4G / LTE temporarily (not sure how this is related exactly, but I couldn’t access the camera via the app, until I did this).

Below are 2 screenshots of the default settings of the Caddx Tarsier camera.

Some of the available resolution options are 4k 30fps, 2.7k 60fps and down to 1080p. I’ve only recorded at 4k 30fps and 2.7k 60fps. The audio can be enabled and disabled and it’s surprisingly usable, given how the props sound on such a tiny quad. You can change the video encoding between H.264 and H.265, adjust the white balance, exposure and ISO. I didn’t touch any of those as I wanted to review the stock experience first. I’ve also been told not to touch EIS (some sort of stabilization, which is buggy at the moment). Will update this article as soon as this is no longer the case.

If you tap Device Settings you get to the second screen of options.

Here you probably want to change the default Start Action from Loop Video to Normal Video, to allow for normal video recording with no shenanigans as soon as you plug in a battery. You can change the default WiFi password, the video standard, factory reset the camera or format the SD card. That last one you probably really want to do, because it solves an issue I ran into.

I was connected to the camera, could see the live video feed just fine and I decided to test the camera by recording a clip.

Caddx Tarsier live video feed via the app

So I pressed the big red record button and saw this message No Sd Card.

Caddx Tarsier no sd card message

But I know there is an SD card inserted. So I headed onto the formatting option via the app and did just that.

After that, I was able to record clips just fine. Or … sort of. So my advice to you is make sure you format your SD card via the Caddx app. It’s better to do it anyway and test to avoid disappointments with missing or corrupted footage.

Speaking of which, I had my fair share of the latter and the former. My biggest issue was with my last battery of the day always ending up to be a 1.4 MB file, corrupted and unplayable. I’ve recorded at 4k 30fps, at 2.7k 60fps and I know it’s not the quality or the speed of my card, as it records every other battery pack I fly just up to the last one just fine. I know I’m not running out of space either. I feel like for whatever reason the camera is not able to write that last file. It could be something I’m doing wrong, but never the less if it happens to me it could happen to other people too and it’s better if you are aware of this as well. One thing I’ll try next would be to unplug and then re-plug the battery after the last flight and “give it time to write the recording” to the SD card. That’s my tinfoil hat assumption of what might be going on. I will come back here and update the article as soon as I have more information.

For now, take it for what it is, but this definitely adds to the poor user experience even if “I’m doing something wrong”. I’m doing the same thing with my Caddx Turtle V2, RunCam Split Mini and RunCam Split 2 and all of the always record and save all the footage correctly to the SD card.

Now even if the user experience suffers, I have to point this out - the Caddx Tarsier 4K camera is outstanding and does remarkable things for our hobby. The FPV feed is one of the best I have seen to date, the recorded DVR is crisp. The 4K sensor is pretty unrivaled too. In September 2019 there’s still no other 4K FPV cameras on the market (or are just starting to come out) and the quality of the video recording is superb.

🚁 Flying

GEPRC CinePro ready for taking off

We are finally ready to go fly and here’s how the maiden flight turned out. This is the 4K 30fps flight footage. Unfortunately, that flight ended up with a failsafe about less than a hundred meters to my 8 o’clock. I’m not sure what was that about, but the GEPRC records black box data in built-in on-board flash memory and I will investigate this further.

I enjoyed flying the CinePro a lot. It was very different than most other quads I had flown to date. I love 5-inch drones and zippy micro quads with brushless motors. But the GEPRC CinePro is surely different and that’s ok because it has a completely different purpose.

I tried flying it “cinewhoop styled” as much as I could - small camera tilt, slow, smooth. My first observation was damn, this thing is so easy to operate in tight spaces. You could get it to move very slow and steady and stall so much almost as if standing still. This is particularly important if you are shooting in 4k 30fps and want steady and slow shots - I think the GEPRC CinePro would do remarkably well in such conditions.

That’s also not to say that the CinePro can’t pull its weight, it could zip around pretty nice too, even if not at top speeds. Check out the slightly faster paced 2.7k 60fps footage below. You can also get a sense for how the props sound through the camera’s microphone (albeit the volume was reduced, but still usable sound quality).

I mentioned the maiden resulted in a failsafe and although the quad dropped from pretty low, I still lost 1 motor screw and the Caddx Tarsier’s wifi antenna. The camera’s position also changed due to the impact.

My advice for you is to make sure you tighten all motor screws every few flights or so, to avoid this (or go for a Loctite solution to the problem), and maybe take the wifi antenna off and keep it off the craft while flying. If I’m honest I’m not sure what it accomplishes as you can still access the camera just fine, so maybe it’s just that the bandwidth would suffer if you copy over files via wifi. I don’t do that anyway, as I find it way easier to copy over files straight from the SD card on a computer.

GEPRC CinePro lost a motor screw

As far as the changed camera position goes, make sure to tighten those screws nicely, but I’ll surely be paying attention if they keep on getting loose over time.

GEPRC CinePro camera tilt reversed in impact

All of the above has been tested with the default Avan Flow 2 props that come preinstalled on the quad. And I’m in the process of waiting for some sunny weather to go fly the Dalpros and see how the flight characteristics compare. I’ll make sure to come back and add the relevant footage as soon as I do.

You could also subscribe to my Georgi FPV YouTube channel where I drop all single pack unedited footage and see the dalprop footage as soon as I upload it.

UPDATE: here is the video of the GEPRC CinePro with the Dalprop Cyclone q2035c props. The quad still flies smooth and nice, I do feel that the handling with the Avan Flow props is a bit easier, but they are also more amp hungry. Both prop options work really well with this quad.

🔋 Batteries

I used 4S batteries for my tests which to my understanding are recommended by GEPRC. You can also fly it on 3S if you have such batteries laying around.

I used a 500 mah Turnigy Graphene battery…

Turnigy Graphene 500 mah 4S battery

… as well as GNB 4S 520mah high voltage batteries (although I still only charged them up to 4.20 volts per cell).

GNB 4S 520 HV batteries

I think the performance was slightly better with the GNB batteries in general, maybe slightly longer, but for the most part, it was rather similar. That’s understandable, given they offer you 20 mah more. They also fit better and are a bit less clunky. If you go the extra mile and charge them up to 4.35 volts as they are high voltage batteries, I’d say you can’t go wrong if you go with those batteries.

📑 Conclusion

What’s the verdict? Is the GEPRC CinePro 4k for you? The answer is that it depends!

Are you excited to do some cinewhooping? And you wanna make your entry into this subset of FPV with the best components, highest quality build, the best 4K split-type camera on the market? Then, by all means, go for it! The GEPRC CinePro 4k is well worth the money it asks from you and you will have an awesome time flying and shooting cinematic videos safely really anywhere. It’s a great offer, though to beat.

The quad flies superb, is decently tuned, flies smooth and is ridiculously easy to handle in VERY tight spots and I mean it!

If you want a quad that’s closer to a freestyle/racer type of a drone, I’d hold my horses on that one. That’s not to say that the CinePro is slow or anything, it’s plenty fast, but it should not be compared to freestyle or racing drones as it is designed for a fundamentally different thing and it does that exceptionally well. This is truly a cinewhoop in the best possible meaning of the word and a top of the line cinewhoop too.

I’d wrap it up saying that the GEPRC CinePro 4k is one of the easiest ways to get into high-quality 4K cinewhooping. Happy flying!

Reader Q & A:

“Hi there. Have You tried to set up an RPM filter on this quad? If so what’s your opinion, and what firmware version have You usedfor the ESCs?” - P

I haven’t done anything RPM filter related on this quad, so sorry I can’t be of help with that particular topic. - Georgi


“Hi, do you have eu version of the frsky radio?” - Libor

I’m currently using FCC, I have used LBT (eu) previously too. Perhaps this can help with some information on how to switch if you need to.


“Nice tuto m8… But I have a question. How can I change the auto start recording camera to no start as soon you connect the battery? Thank you in advance.” - Rod

Try changing the Start Action in the camera app. Failing that, check the camera documentation if you could do that with the physical buttons on it (maybe by pressing and holding the power button?). - Georgi


“I found how to change the auto start recording :) but now I have another question. How you change the VTx power? Thanks again.” - Rod

You can do that via the OSD by going full yaw left and pitch up to display the menu. - Georgi


“I have same problem with latest video on sd card. It says corrupted video. Let me know if you find out why that is. Great article. Thanks, Chris”

From all the googling and testing I did, it seems to be a “by design feature”. I don’t like it but it is what it is. To make sure your last flight always gets correctly saved, when done flying, unplug the battery and plug it back in for a few seconds. This should give the camera enough time to write the video file correctly to the SD card. Again, I don’t like it, but I can confirm it works reliably. - Georgi


“Thank yo for this review and set up guide Georgi! This guide and video has helped me very much, however, I can not get my LED’s on the tail end to light up. I’ve used your CLI you’ve linked to but they still won’t illuminate. I have the F7 FC (advanced version). I’m very new at this and still learning so any information would be very helpful. Thanks”

I’m also using the advanced version and my tail LEDs are just blinking by default. If yours don’t light up at all, I’d check the wiring and have a look at the LED strip tab in Betaflight. Maybe something is disabled there? Good luck! - Georgi
