Cinewhoops are exceptional small FPV drones, perfect for capturing professional-grade commercials, real estate videos, and cinematic footage. With their propeller guards, they’re also safer for teaching beginners flying FPV drones. In this post, we’ve compiled a list of the best cinewhoops available in 2023. Explore these top choices to enhance your filmmaking and flying experience.

What is a Cinewhoop?
Cinewhoops are a unique type of micro FPV drones, featuring propeller guards (also known as ducts) and they can carry action cameras, like GoPros, for capturing smooth aerial footage. While not as fast as 5″ freestyle FPV drones, Cinewhoops prioritize safety and stability, allowing pilots to safely fly close to their subjects indoor and outdoor. The resulting footage boasts a level of cinematic quality that is nearly impossible to achieve with a 5″ quad.
Advantages of a Cinewhoop
- Safe indoor flying with propeller guards for added protection
- Smooth and slow flight capabilities, ideal for capturing relaxed cinematic shots
- Budget-friendly, thanks to their smaller size and less powerful components
Disadvantages of a Cinewhoop
- Shorter flight times due to the extra weight and relatively inefficient propeller motor combo
- Less nimble and slower compared to typical freestyle drones
- Steady cruising is a strong suit, but not the best choice for performing freestyle moves
Cinewhoop Sizes Explained
Cinewhoops come in four sizes: 20, 25, 30, and 35. These numbers refer to the propeller sizes, with 20 being 2-inch, 25 being 2.5-inch, 30 being 3-inch, and 35 being 3.5-inch.
Smaller cinewhoops are more compact, lighter, less intimidating, and easier to carry around, allowing them to navigate through tighter spaces. Larger cinewhoops, on the other hand, are more powerful, handle strong winds better, provide greater outdoor stability, and can carry heavier payloads such as a full-sized GoPro.
If your goal is to stay under the 250g limit, a 2-inch cinewhoop (size 20) is ideal. With a battery and a naked GoPro, you can typically remain under 250 grams. A full size GoPro would be too heavy for them to handle. If you opt for a model with a DJI O3 Air Unit, you can eliminate the need for an additional action camera, resulting in a more compact setup that still can capture high-quality video.
For carrying a Naked GoPro or GoPro Bones, a 2.5-inch or 3-inch cinewhoop (sizes 25 or 30) is recommended. While these sizes will likely exceed the 250-gram limit with the action camera and battery, they offer better stability, speed, and outdoor handling. A 3-inch cinewhoop may be able to carry a full-sized GoPro, but its performance will likely suffer. If you plan to fly outdoor, the 3-inch would probably perform better than the 2.5-inch, however for indoor only, the 2.5-inch can fit into more spaces and you won’t need the extra power from the larger propellers provided by the 3-inch.
To fly outdoor and carry a full-sized GoPro, such as the GoPro Hero 11 Black, a 3.5-inch (size 35) cinewhoop would be the best choice.
For beginners learning to fly, all cinewhoop sizes will do the job. If you plan to use a GoPro later, sizes 30 or 35 offer greater versatility. If you want a small drone for casual park flying without a strong focus on video quality, sizes 20 or 25 are best. Keep in mind that larger cinewhoops handle wind better, so consider local weather conditions when choosing your drone.
Though the onboard FPV camera isn’t as good as a GoPro, adding an action camera to your cinewhoop is recommended for the best possible footage. See my action camera recommendations: https://oscarliang.com/action-camera/

Choosing the Right Battery for Your Cinewhoop
Selecting the right battery for your Cinewhoop depends on various factors, including motor KV, propeller size, drone weight, and desired flight time. You don’t need an overly large or expensive battery with an extremely high C-rating typically used for racing, as Cinewhoops primarily focus on capturing smooth and relaxed footage, rather than aggressive flying.
Ensure that the battery has a matching connector for your drone, such as XT30 or XT60, to avoid compatibility issues. To find the recommended battery size and cell count for your specific drone, refer to the product page and specifications provided by the manufacturer. This information will help you choose the most suitable battery for optimal performance and flight time.
Selecting the Ideal Propellers for Your Cinewhoop
Cinewhoops often carry significant weight relative to their size, including propeller guards, a large battery, and a GoPro camera. To accommodate this weight, you typically need to increase the propeller size to generate more thrust and enhance efficiency. However, Cinewhoops are generally limited to 3.5-inch or even smaller propellers due to their compact size.
Bullnose propellers are a popular choice for Cinewhoops because they generate more thrust compared to pointy propellers, despite being less efficient. Pointy propellers, while more efficient and have some advantage in other types of FPV drones, may not be the best choice for Cinewhoops due to their lower thrust output.
To further increase thrust output, it’s common to use propellers with more than three blades. Five and even six-blade propellers are popular choices in Cinewhoops, as adding more blades effectively increases the surface area, increasing thrust production.
Since propellers are relatively inexpensive, testing various options with your specific setup is the best way to determine the ideal choice. When evaluating propellers, consider the following factors:
- Efficiency: How does the propeller affect flight time?
- Noise level: Quieter propellers are less likely to disturb people nearby.
- Power: Assess the thrust produced and the amount of throttle required to maintain hover.
- Smoothness: Determine if the propeller causes additional vibration.
- Responsiveness: Evaluate whether the propeller improves flight performance.
By considering these factors, you can select the most suitable propellers for your Cinewhoop, ensuring optimal performance and flight experience.
FAQ & Tips
Best Camera Angles for Flying Cinewhoop
The general consensus for optimal FPV camera tilt angle is 10-20 degrees, while a slightly higher angle is recommended for the GoPro due to its wider field of view (FOV).
Best Flight Mode for Cinewhoop
Both Angle and Acro modes can be used for Cinewhoops, depending on the flying environment. However, Acro mode is preferred in most cases, as it offers smoother flight performance. With Angle mode, you might constantly need to counteract the self-leveling which results in more wobbles in the footage.
Flying in Acro mode indoors is not significantly more challenging. You can transfer your regular flying skills to indoor environments by simply reducing the camera angle. When using Angle mode, consider reducing the angle strength to 20, so it doesn’t resist your inputs as much, providing a better flying experience.

Hello Sir, thank you for that list.
I am a bit confused about your statement about the BetaFPV Pavo25.
You say that it is “one of the lightest 2.5″ cinewhoops”. But as you also wrote in your review about the Pavo25, the predecessor (Beta 95X V3) is 40 grams lighter! And they removed the rubber damping for the HD camera on the Pavo25. The Beta 95X V3 is already quite loud but the Pavo25 is much heavier with the same motors and propellers so even louder. I think this is a big step back and this quad definetely should not be listed as “one of the lightest 2.5″ cinewhoops” since even the predecessor is much lighter.
I put my Beta 95X V3 online some days ago and was surprised that some people wanted to pay more that I paid when I bought it new because of the problems with the Pavo25 (heavier, louder, no damping). Now I will keep it. because I couln’t find a better one and found some props that are quieter than the original ones, this is my test:
https://www.youtube.com/watch?v=gIOtVS_gIOM
Cheers!
Hello sir, im just new. and im having some issues with my 3inch cinewhoop. iwas a Cloud 149 v2. with 1806 2280kv motors running on 4s with a 5 bladed props.
It has a Gopro Mounted on top. When im flying outside, im having some wobbles everytime I turn, and even when im just cruising around. What should I do?
already tired different battery sizes 850mah 1100mah and 1500mah. but it’s just the same.
Your motor kv is for 6s
Hello oscar, I’m struggling to figure out how to fix this wobbles while im turning and even when im crusing around with my 3″ Cinewhoop, it was a Cloud 149 V2 frame.
tried different batteries but it flew just the same but different flight time, 850(4mins) 1100mah(5mins) 1500(mins)
running it with a 1806 2280kv motors on 4s with a hero 5 full size on top.
Here’s my clip, youtube.com/watch?v=naUFdd1zL28
It looks to me PID might need some tuning? It’s hard to say without blackbox, but I think it looks like I gain is too high, try lowering it see if the wobble gets better?
I just watched a pretty long introduction on PID Tuning before I tweak some of the numbers and sliders here. I’ve watched Chris Rosser’s video, he said that “the D->P->I” it was need to be tweaked from d-term to i-term.
But he said, that the betaflght P:D balance was good enough and tweaking manually might make my quad worst. Should I use the Master Multiplier instead? and if I do should I lower it down or up?
Though I know this will be a trial and error, where do I start? Sorry I’m a complete noob just started 2 months ago and I’m trying to get into FPV world.
Thanks in advance Oscar!
currently new to FPV and i have the betaFPV 95x with crossfire…
i was wondering how i can tune my cinewhoop to have a much more smoother flight? it feels like theres just too much sensitivity when steering and also when im trying to use the throttle.
Tips would be appreciated!
You can play around with rate and expo, these are the stick sensitivity settings.
Is motors direction for a pushup style configuration (CineLog for instance) differs from usual direction?
Depends on if you want to run props out or props in, then you mount CW/CCW props on accordingly. But when you mount the motors up side down, the direction would be reversed.
All of those cinewhoop fly like crap except the shendrone squirt.
Also, don’t bother with 140x or 150X motors unless you’re running a naked gopro sub 250g, you’ll get wobbles and motor over heat, and the drone will go crazy if you try to do a small dive. Save yourself the time and get a 2203.5 motor like FPVcycle or Xing.
In terms of frame, get the cloud 149 and go print some tuned ducts for the prop you’re running. Make sure your prop clearance is 1mm or less and get slammed ducts, they’re much quieter and efficient.
amazing blog Oscar. You got me into the FPV world!
Your thoughts on a bottom mount setup for cinewhoops?
I’m messing around with a little TinaWhoop frame (I realize it’s not a true cinewhoop) and wondering why Cinewhoops don’t prefer bottom mount batteries.
Going for smooth and stable vs agile and responsive flight characteristics. Does bottom mounting the battery not help accomplish this? Also considering the difference between toilet tank vs the ‘normal’ orientation.. Any thoughts on this ?rotorbuilds.com/build/26798
Hey Oscar
I’m around 30 h into my fpv journey. So far I only flew in the sim and that will continue until I get around 70-80 of fly time.
My question is are there any hybrid builds between a ordinary freestyle drone and cinewhoop? As a begineer I want to mainly
focus on smooth cinematic flying with occasional freestyle.
There’s no such thing as a hybrid of freestyle and cinewhoop. A cinewhoop is quite specific because it has some beefy ducts.
If you want something for training, that can do freestyle, and translate your skills better to cinewhoop, I’d recommend the GepRC Rocket. It’s got ducts, it’s small and it flies amazing. It’s 2″ quad, so flight characteristics would be more similar to a 3″, than say a 5″.
Hi Oscar my name is Bong I’m a new cinewhoop pilot do you have a smooth rates for a reptile cloud149 v2? thanks in advance peace! :-)
Hello Oscar.
iam happy i found your blog.
can i use 1300mah hour with a drone that the manufaturer recomends 850mah?
this recomendation is only about the weight of the drone?
Of course as long as it’s not too heavy for the drone.
Hi, my name is Marcelo and I write you from Buenos Aires, Argentina. I want to know if I can use Iflight Green Hornet v2 6s with 4s batteries or I can’t. Because I have 4s batteries y for the same price I can to buy the 6s cinewhoop instead of the 4s version. Best regards.
Hey Oscar, thanks for another great article. I got the Megabee a little while back, I recently upgraded the ducts to some aftermarket ones, with foam on outside like the bumblebee, and went ahead and upgraded motors. I went with the Xing 1507, 3000kv motors. Just finished the other day, only got a couple packs in on them, they seemed pretty good, but need to test out different. props. Wondering was 3000kv too low to go, and is lowering kv more crucial to increasing prop size or increasing motor size? Thanks!
????: ??????? ????? ????? ???? 1406 3600??, ? ??? 4? ?????? 1000??? ?? 1300???.)
Oscar, why you don’t consider Dji Osmo Action camera?
Stabilization isn’t as good as Hypersmooth, yet.
dont buy an echine novice 1 the dtrone is ok but the controller and goggles are gasrbage thankfully i havre a pair of AOMWAY commander V1S they rock abnd jumoper T16 for transmitter fits nicely
Sir wht betaflight version u use for yr cinehoop … ? I hear that 3.5 is good for cinehoop ? Sir pls give information about yr betaflight version …
Is it possible to build a cinewhoop sub 250g with a 3s battery with a DJI system or caddx vista which is 30gms
As far as gopro is concerned. There is option of using a decased go pro which is around 25gms only.
Look and sound neat. Need more info on buying them.
I have rcinpower gts v2 1506 4300kv and T-Motor F20II 1408 3750kv, for diatone taycan frame which one should i choose ?
I’m building a cw on a reptile Cloud frame and t-motor f1507 Motors. Which propos would you recommend? I know that the space between the props and ducts shoul be minimal. Should i buy some bigger props and file them down?
Yes you can certainly cut down bigger props. Honestly you should try a few different ones at least, everyone has a different standard as to which props work the best, some might prefer a powerful prop, some might prefer a quieter one.
