What’s a Tiny Whoop?

A Tiny Whoop is a small indoor FPV drone featuring 31-40mm propellers, protective propeller guards (also known as ducts), and 65mm or 75mm frame wheelbases. They usually operate on 1S or 2S LiPo batteries. Tiny Whoop is a trademark by a US-based company that popularized this type of micro drones, so people in the hobby simply call all these small drones “Tiny Whoops”. These affordable, easy-to-control FPV drones are perfect for indoor flying and can also be flown outdoors in wind-protected areas. Their ducts ensure safety and reduce damage upon crashes.

Best 65mm Tiny Whoops

These 65mm Tiny Whoops are small, relatively quiet, and easy to control, making them the best whoops for indoor flying. A few bind and fly models stand out due to their superior performance, durability and value.

Best 75mm Tiny Whoops

If you are looking for a more powerful whoop, or perhaps something that can even fly outdoor, 75mm whoops are a better choice than 65mm. There are also more options when it comes to HD Digital FPV systems.

Mobula7 1S

Happymodel Mobula7 1s Bnf Tiny Whoop Front

The Mobula7 1S builds on the strengths of Mobula6 by offering a larger platform with bigger propellers for increased power, speed, and flight time. All these strengths contribute to a more “all around” whoop. Although slightly less agile due to its heavier weight, the Mobula7 1S excels in raw power and speed, makes it more fun to fly in larger indoor space, even possible to fly outdoor on a calm day. It also provides improved hardware and easier camera tilt adjustments. This would be my go-to tiny whoop if you can only choose one. See my full review of the Mobula7 here: https://oscarliang.com/mobula7-1s-whoop/

This affordable 1S tiny whoop can be easily adjusted to reduce power for indoor flying by changing the camera angle and limiting max throttle. Tutorial: How to reduce max power?

BetaFPV Meteor75 Pro

Betafpv Meteor75 Pro Hd Whoop Walksnail Compare Analog

The BetaFPV Meteor75 Pro is a 1S Tiny Whoop that is available in various FPV systems: analog, Walksnail Avatar and HDZero, delivering a game-changing HD video feed. It has integrated ExpressLRS, providing excellent range. It’s using slightly larger propellers, which gives them extra power and stability for flying outdoor. However, the Meteor75 is heavier than the Mobula7 due to the larger size, impacting its agility especially when flying indoor.

Despite this, the Meteor75 still offers a smooth, enjoyable flying experience, and the stock PID tune is decent. Personally I recommend the analog version, because HDZero and Walksnail VTX’s just don’t work well with 1S (they shut down prematurely when voltage drops below 3.3V), but the HD video provided by Walksnail VTX is impressive nonetheless, providing clearer, more immersive visuals. Also note that the analog version is significantly lighter and so it also flies much better too. If you are looking for a 1S tiny whoop for flying outdoor, this is worth considering.

Wheelbase: 65mm vs 75mm

Right: 65mm tiny whoop, Middle: 75mm tiny whoop

Wheelbase refers to the size of the frame, which is the distance between two diagonal motors. For tiny whoops typically comes in two wheelbase sizes: 65mm and 75mm.

The 65mm whoops are the classic, they are more agile and easier to control, and the more popular choice for flying at home since they are also slightly smaller. On the other hand, the 75mm whoops offer greater power due to their larger propeller and batteries. Some might find them harder to control than the 65mm but they are more versatile and faster.

If you’re undecided between 65mm and 75mm whoops, 75mm generally offers longer flight times, faster speeds, and better stability for outdoor flying. However, 65mm whoops are more agile and can navigate smaller gaps. Some racing events only permit 65mm whoops, so take this into account if you’re serious about racing.

Brushed Motors or Brushless Motors

best tiny whoop round up comparison

Tiny Whoops utilize two types of motors: brushed and Brushless. In summary:

  • Brushless whoop: more powerful, better motor longevity, supports turtle mode, 48kHz, and RPM filter
  • Brushed whoop: cheaper, simple, and lightweight

Previously, the decision between motor types for a tiny whoop was more challenging. However, with the introduction of performance features such as RPM filter and 48kHz support in BLHeli_S, brushless motors have become the standard while brushed whoops have become obsolete.

Battery Cell Count: 1S vs 2S

1s vs 2s tiny whoop

Learn about LiPo cell count in this tutorial: https://oscarliang.com/lipo-battery-guide/#cell-count

Tiny Whoops typically operate on 1S or 2S battery packs, with 1S signifying one cell and 2S representing two cells. Typically, the higher the cell count, the more powerful the drone.

1S whoops are lighter, quieter, safer, and cause less damage during crashes, making them ideal for casual indoor FPV flying. On the other hand, 2S whoops are more powerful and more suited for outdoor flight in calm weather or for lifting heavier payloads, such as better cameras or FPV systems. However, they might be harder to fly indoor in tighter spaces.

LiPo Battery Connectors

Lipo Battery Connector Testing Size Compare Bt2 Ph2 A30 Xt30 Gnb27 1s Micro Fpv Drone Tiny Whoop Performance

As tested, BT2.0 and A30 connectors are the ideal choices for tiny whoops by providing stronger power and slightly longer flight times. This is due to their lower resistance and less voltage drop under load. While PH2.0 connectors are functional and adequate for everyday flying, you should use BT2.0 or A30 whenever you can and avoid PH2.0.

If your whoop have a PH2.0 connector, you can easily replace it with a BT2.0 connector if you know how to solder. Avoid using a PH2.0 to BT2.0 adapter, as it introduces additional resistance and negates the benefits of the superior BT2.0 connector.

It’s essential to choose a connector type before bulk purchasing LiPo batteries to ensure they have matching connectors.


Essential Accessories and Parts

Here are some useful accessories and parts for tiny whoops.

Battery Considerations

Voltage: LiHV vs LiPo

Most tiny whoops use LiHV batteries for higher power and capacity at a lower weight, while also being compatible with LiPo batteries. LiHV batteries offers superior performance for micro drones as tested here, and that should be your default option.

Connectors: BT2.0 vs A30 vs PH2.0

Batteries connect to your tiny whoop via a connector. The majority of tiny whoops have a PH2.0 connector, so ensure the batteries you purchase are compatible. Watch out for battery connector, A30/BT2.0 are not compatible with PH2.0.

Note that you can use A30 batteries with BT2.0 connectors on the quad, You might be able to use BT2.0 batteries with A30, but you have to plug it in forcefully which might damage the plastic over time.

Cell Types

If you’re focused on performance, consider opting for ‘folded/square cells’, which outperform traditional ‘rolled/rounded cells’. Folded cells are more efficient and exhibit less voltage sag. As of this writing, to the best of my knowledge, Tattu is the only manufacturer producing folded cells (their 1S 300mAh and 450mAh HV lineup) in 2023, but that could change in the future. Other companies, like WeBleedFPV and TinyWhoop, rebrand their batteries using the same cells. The rest on the market are primarily rolled cells.

Rolled cells deliver decent performance, especially when paired with a quality connector like the BT2.0. However, for the best possible performance, squared cells are preferable.

So why aren’t folded cells used in larger batteries? Beyond a certain capacity threshold, such as 500mAh, the cell size is sufficient for traditional cell types to perform comparably to folded cells. Folded cells are particularly advantageous in compensating for the limitations of very small sizes, like 300mAh and 450mAh.

Performance

If you are looking for flight time at relatively slow speed, you should get a battery with high capacity to weight ratio. However for most of us who fly tiny whoops, we constantly doing acro moves and tricks, power and voltage sags are more important considerations.

Motors

It’s a trend in tiny whoop motors to use higher KV with tri-blade propellers, such as 25000KV and 26000KV, as they give you more power. In a nutshell, higher KV means the motor will spin faster when apply the same voltage. See this post for a more detailed explanation: https://oscarliang.com/motors/#KV

For bi-blade propellers you need high RPM to unleash the desire power, typically pairing them with motors in the 28,000 to 32,000 KV range gives great result.

While experienced pilots can undoubtedly harness the full potential of high KV motors, beginners and intermediate flyers might find them too aggressive. Instead of using low KV motors, I’d recommend starting with a minimum of 26,000 KV motors and then cap the throttle or motor outputs to tame the power if necessary (you can do this either in the radio or Betaflight settings). With this method, even less experienced pilots can gradually build up their skills to flying higher KV motors while having the flexibility to control their power.

For 65mm whoops, 0702 is a popular motor size, choose between 26000KV and 30000KV depends on your propeller choice. For 75mm whoops, 1002 is a great motor size. For heavier builds with digital VTX’s, consider even bigger 1102 motors.

1002 is great for analog whoops, and

Happymodel SE0702 Motor

VTX Antenna

TrueRC Singularity 5.8GHz Antenna with Short U.FL

Most BNF Tiny Whoops come with a simple whip antenna (linear polarized dipole antenna). They are ok, but upgrading to the TrueRC Singularity Antenna offers noticeable performance improvement while only adding half a gram of extra weight. If you are struggling with video signal when flying indoor, you should consider upgrading to a circular polarized antenna. I explained why circular polarized antenna are better for FPV than linear polarized antennas here.

ExpressLRS Receivers

Elrs Lite Receiver Ceramic Flat Antenna

Left: ceramic antenna; Right: flat antenna

ExpressLRS has emerged as the best radio control link for Tiny Whoops for numerous reasons. Firstly, it’s open-source, making it readily available and adaptable. This feature has made it easy for manufacturers to incorporate it into their flight controllers.

Furthermore, ExpressLRS offers excellent range and penetration, outperforming many competitors in the market (such as Frsky D8/D16). Also telemetry is fully supported in ExpressLRS. Admittedly, it can be somewhat tricky to set up initially for some users, but once mastered, its performance and versatility make it worth the learning curve.

Many new tiny whoop flight controllers offer built-in ELRS receiver, but if not you can also hook up an external ELRS receiver if there’s a spare UART. The RX is very lightweight, and the antenna is compact and doesn’t require mounting. Make sure to get the ones with ceramic antenna (or flat antenna) for space saving.

For an updated list of receiver available, check this list: https://oscarliang.com/setup-expresslrs-2-4ghz/#Receivers

Using Throttle Expo for Indoor Flights

To make your drone easier to control when flying indoor, consider using some throttle expo.

Throttle Expo refers to exponential throttle curve adjustments, allowing more precise throttle control in tight spaces, especially when most whoops come with powerful high-KV motors these days.

With high-KV motors, there’s a tendency to lose significant throttle resolution, which can make precise control challenging. But when flying indoors, you’re usually hovering or cruising around 30-35% throttle. Applying 20-30 throttle expo around this throttle value can make control more precise and easier.

Learn more about Throttle Expo here: https://oscarliang.com/throttle-curve/#Adjusting-Throttle-Curve-in-Betaflight

What’s the Best DJI O3 Tiny Whoop?

First and foremost, the DJI O3 Air Unit, while a marvel in FPV technology, introduces significant weight constraints. This is particularly problematic for drones designed to excel in tight indoor spaces.

While there are pilots showcasing their skill with 85mm whoops in cramped quarters, such feats are more the exception than the rule. For the majority, a 65 or 75mm whoop provides the agility and safety needed for indoor flying. However, by the time we scale up to an 85mm drone, the added speed and weight will cause more damage when you crash.

If you insist on flying an DJI O3 drone indoor, I would consider one of the 75mm whoops, such as the BetaFPV Pavo Pico or Flywoo Flylens 75. But I found even these drones are a bit too heavy for flying indoor safely and comfortably.

Walksnail offers light weight 1S VTX that is way more suitable for indoor light weight tiny whoops, but they suffer from premature shutdown when voltage drops below 3.3V which might not be ideal for some people.

Hello Oscar. Thank you for article. What do you think about BetaFPV 0702/0702SE motors? They are more expensive then Happymodel, but are they really better?

Steve 2nd October 2023 - 3:38 pm

Might want to change the bit about NBD and customer service… the BLV4 ELRS comes with bad motor plugs and the offical support guidance is to cut the wires shorter and resolder (this also doesnt fix the issue). Not a job for someone new to the hobby! Plus the plug came off the board when i tried. Original issue is the motors stutter on arm as the plugs are of low quality.

I’d add a couple of comments on the BetaFPV AIO 5A board.

The latest (V2) has a UART connected ELRS receiver, The V1 was SPI. If one wants to avoid compatibility grief then UART as opposed to SPI is good, because both Betaflight and ELRS are fast moving projects and with SPI the ELRS code is in Betaflight. So it is not always possible to find the Betaflight you want with the ELRS you want. With UART connected ELRS, the ELRS code is independently flashed.

The other is that the motor connectorless version saves around 3/4g, is not going to suffer from unexpected voltage drops in motor lines (picoblade connectors are pretty low current rated) and the pads are big enough to make soldering motor wires (relatively) easy.

can u please add the meteor pro 65 now?.. mainly because they are now using 35mm props?
i find it interesting that you say that the 35mm prop whoop isnt as nimble. it really should be as whilst there’s an extra 10% of weight, there is an extra 25% of thrust. that thrust is used in extra torque for yaw and more than makes up for the extra inertia from the 2g increase. it doesnt make sense to be honest.

The Mobula6 actually has 25mw, 100mw, and 200mw VTX output power. It’s on 200mw out of the box but you can use lower power by adding power options in betaflight. 25mw is suitable enough for a whoop and sometimes even better indoors than using 200mw because of multipathing. The SPI RX is more limiting than the VTX. I get failsafe issues before the video gets bad even on 25mw.

It seems moblite is discontinued and you can’t find it anywhere… That’s weird…

I am looking for a timing system for whoop fpv racing. Do you have any suggestions? Most systems I have found are out of production or the app is not available.

Hi I am very new to fpv drones so just bought a Dji fpv set (drone, goggles, remote, motion controller). However I’d like a small drone for flying indoors. Will any of these connect to my Dji remote and goggles?

no, none of these will connect to your DJI

I too have the DJI setup. I am interested in indoor flying. Is there a small, prebuilt whoop that is compatible with digital HD for indoor use? Beta95x and GEPRC Cinelog25 are probably too powerful for indoor use?

What’s with the removal of VTXs above 25mW at 1S?

25 mW is so limiting….

can you tell me about a good video to bind a mobula6 to a tx16s I tried to do it but it run fast even on low throttle. I have done something wrong .. I don’t know how to fix it and If I wear goggles and it takes off real fast I may never find it.. Please help me

Boo hoo! my Trashcan overheats via core temperature and the screws under the motors are scalding hot after 1 battery. I want to be a fan of it, I really do.. but no reduction in d-gain, filtering, fc or motor replacement has helped.

I’ll try the forums, but I’m disappointed I can’t make use of it in my fleet.

HI Oscar can you please mention what FrSky transmitter is capable to connect to a D8 receiver like the Mobula 6 or TinyHawk 2?

Do not buy brushless whoops with 0603 motors. Replace them to 0802 (even for 1S ) and you will get 30 sec more flight time with exactly the same performance. If you already have 0603 motors consider flash ESC with mod firmware. Please see mshtools.c1.biz/2019/03/01/0603-vs-0802/ and mshtools.c1.biz/2019/02/14/30-more-flight-time-by-esc-fw-mod/

31mm props or it ant a whoop!

ill counter that and say a whoop is 65mm from motor to motor in the frame diagonally. it is possible to cram 40mm ducted props on there. THATs a whoop!.

Good article. Last year I bought a Eachine Aurora 68 and it flew not good out-of-the box. I had a lot of work (more than some 5″ builds) to bring it to good performance. It’s nice bit still a bit too powerful (2S) and heavy for tiny European living rooms. So I bought a UK65 this year (pre-sale). After applying the Mockingbird setting it flew very well but the frame is really fragile. After I broke the battery holder and a piece out of one duct I put “it” in a BetaFPV 65pro frame. Now its a great little whoop.

Loving the new 2S Whoop category. I have the BetaFPV 75X, and hoping to get my hands on a Mobula 7 soon. The 75X definitely rips around my small neighborhood, it’s on my par with my 2.5″ builds in terms of speed, but not quite there on agility. Still very impressive, and looking forward to trying out the Mobula 7.

If you are in the market for a 2S wh00p, I suggest going to ebay and searching for the Mobula7. A few days ago, I happened to stumble upon a 24 hour 10% off everything on ebay coupon. Obviously that is expired, but with Black Friday coming up, and sites wanting to expand on the Black Friday hype train, I’m sure if you keep a tab open on your browser and casually click it once a day, you’ll be finding another coupon in not long. It took me a couple of days of thinking about purchasing it to stumble upon that coupon. Now, they’re only 77 bucks and change on ebay without coupon!! – with Free Shipping to the USA, so it’s not like the 10% off coupon saves you a ton! I got mine for $69.65 for the Basic, as I already have that stellar charger. Get the Standard version if you don’t have the charger as it’s easily worth the difference in price they want to upgrade.
BONUS – both kits come with 4 of the stick 1S wh00p batteries! Good Luck, and stay warm and fly indoors this winter! :)

Great article! I love the new waive of brushless whoops that have arrived. Don’t some of the 2S whoops, like the Mobula7, also allow you to fly using just one 1S battery? Wouldn’t that the solve the problem with flying indoors by decreasing the power?

I can speak for the 65x, as I have one. It doesn’t power up until you connect the second battery. So plugging just one in does not work.

Reply
Oscar 6th November 2018 - 12:51 pm

No, they have two connectors connected in series for two 1S batteries, so you’d have to connect both batteries for it to power up.

Mobula 7 came with a jumper so I can fly it 1s, I found reducing the rates made it not so twitchy so I could fly indoors without much crash landings.
