What’s a Tiny Whoop?

A Tiny Whoop is a small indoor FPV drone that includes 31-40mm propellers, protecting propeller guards (often known as ducts), and 65mm or 75mm body wheelbases. They often function on 1S or 2S LiPo batteries. Tiny Whoop is a trademark by a US-based firm that popularized this sort of micro drones, so individuals within the passion merely name all these small drones “Tiny Whoops”. These inexpensive, easy-to-control FPV drones are good for indoor flying and may also be flown open air in wind-protected areas. Their ducts guarantee security and cut back injury upon crashes.

Greatest 65mm Tiny Whoops

These 65mm Tiny Whoops are small, comparatively quiet, and straightforward to regulate, making them one of the best whoops for indoor flying. Just a few bind and fly fashions stand out as a consequence of their superior efficiency, sturdiness and worth.

Greatest 75mm Tiny Whoops

If you’re on the lookout for a extra highly effective whoop, or maybe one thing that may be flown out of doors, 75mm whoops are a better option than 65mm. There are additionally extra choices relating to HD Digital FPV techniques.

Wheelbase: 65mm vs 75mm

Proper: 65mm tiny whoop, Center: 75mm tiny whoop

Wheelbase refers back to the dimension of the body, which is the space between two diagonal motors. For tiny whoops sometimes is available in two wheelbase sizes: 65mm and 75mm.

The choice between 65mm and 75mm is simple: If you wish to fly indoor, 65mm is the best way to go. If you wish to fly out of doors (in calm climate), 75mm is the higher selection. Not saying you may’t fly a 75mm indoor, it’s just a bit too quick, much less exact and agile. And naturally you may fly a 65mm out of doors too, nevertheless it doesn’t deal with the wind as nicely, and lacks the facility to go quick.

The 65mm whoops are the basic, they’re extra agile and simpler to regulate, and the extra well-liked selection for flying at dwelling since they’re additionally barely smaller. Alternatively, the 75mm whoops provide better energy as a consequence of their bigger propeller and batteries. Some would possibly discover them more durable to regulate than the 65mm however they’re extra versatile and sooner.

For those who’re undecided between 65mm and 75mm whoops, 75mm typically affords longer flight occasions, sooner speeds, and higher stability for out of doors flying. Nonetheless, 65mm whoops are extra agile and may navigate smaller gaps. Some racing occasions solely allow 65mm whoops, so take this into consideration if you happen to’re critical about racing.

Right here’s my suggestions: If you’re simply entering into tiny whoops, a 65mm is a good place to begin – a should have for flying in tight areas. If you wish to fly out of doors or bigger indoor areas, then take into account including a 75mm to your fleet afterward.

Brushed Motors or Brushless Motors

Tiny Whoops make the most of two sorts of motors: brushed and Brushless. In abstract:

• Brushless whoop: extra highly effective, higher motor longevity, helps turtle mode, 48kHz, and RPM filter
• Brushed whoop: cheaper, easy, and light-weight

Beforehand, the choice between motor sorts for a tiny whoop was tougher. Nonetheless, with the introduction of efficiency options corresponding to RPM filter and 48kHz assist in BLHeli_S, brushless motors have develop into the usual whereas brushed whoops have develop into out of date.

Battery Cell Depend: 1S vs 2S

Study LiPo cell rely on this tutorial: https://oscarliang.com/lipo-battery-guide/#cell-count

Tiny Whoops sometimes function on 1S or 2S battery packs, with 1S signifying one cell and 2S representing two cells. Usually, the upper the cell rely, the extra highly effective the drone.

1S whoops are lighter, quieter, safer, and trigger much less injury throughout crashes, making them splendid for informal indoor FPV flying. Alternatively, 2S whoops are extra highly effective and extra fitted to out of doors flight in calm climate or for lifting heavier payloads, corresponding to higher cameras or FPV techniques. Nonetheless, they is likely to be more durable to fly indoor in tighter areas.

LiPo Battery Connectors

As examined, BT2.0 and A30 connectors are the best decisions for tiny whoops by offering stronger energy and barely longer flight occasions. This is because of their decrease resistance and fewer voltage drop underneath load. Whereas PH2.0 connectors are practical and ample for on a regular basis flying, it’s best to use BT2.0 or A30 each time you may and keep away from PH2.0.

In case your whoop have a PH2.0 connector, you may simply change it with a BT2.0 connector if you understand how to solder. Keep away from utilizing a PH2.0 to BT2.0 adapter, because it introduces further resistance and negates the advantages of the superior BT2.0 connector.

It’s important to decide on a connector sort earlier than bulk buying LiPo batteries to make sure they’ve matching connectors.

Important Equipment and Elements

Listed here are some helpful equipment and elements for tiny whoops.

Battery Concerns

Voltage: LiHV vs LiPo

Most tiny whoops use LiHV batteries for greater energy and capability at a decrease weight, whereas additionally being appropriate with LiPo batteries. LiHV batteries affords superior efficiency for micro drones as examined right here, and that needs to be your default possibility.

Connectors: BT2.0 vs A30 vs PH2.0

Batteries connect with your tiny whoop by way of a connector. The vast majority of tiny whoops have a PH2.0 connector, so make sure the batteries you buy are appropriate. Be careful for battery connector, A30/BT2.0 will not be appropriate with PH2.0.

Be aware that you should use A30 batteries with BT2.0 connectors on the quad, You would possibly have the ability to use BT2.0 batteries with A30, however you need to plug it in forcefully which could injury the plastic over time.

Cell Varieties

For those who’re centered on efficiency, take into account choosing ‘folded/sq. cells’, which outperform conventional ‘rolled/rounded cells’. Folded cells are extra environment friendly and exhibit much less voltage sag. As of this writing, to one of the best of my data, Tattu is the one producer producing folded cells (their 1S 300mAh and 450mAh HV lineup) in 2023, however that might change sooner or later. Different firms, like WeBleedFPV and TinyWhoop, rebrand their batteries utilizing the identical cells. The remainder available on the market are primarily rolled cells.

Rolled cells ship respectable efficiency, particularly when paired with a high quality connector just like the BT2.0. Nonetheless, for the very best efficiency, squared cells are preferable.

So why aren’t folded cells utilized in bigger batteries? Past a sure capability threshold, corresponding to 500mAh, the cell dimension is adequate for conventional cell sorts to carry out comparably to folded cells. Folded cells are notably advantageous in compensating for the restrictions of very small sizes, like 300mAh and 450mAh.

Efficiency

If you’re on the lookout for flight time at comparatively gradual velocity, it’s best to get a battery with excessive capability to weight ratio. Nonetheless for many of us who fly tiny whoops, we continuously doing acro strikes and methods, energy and voltage sags are extra essential concerns.

2S LiPo Batteries for 75mm Whoops

Greatest Tiny Whoop Chargers

ViFly Whoop Serial Charging Board

It’s not a charger, however a charging board. It principally connects all of your batteries in collection as a single battery. Not like parallel charging, with collection charging, even when the batteries have very completely different voltage you may nonetheless join them to the board, the charger will stability the voltage throughout charging. All batteries should be of the identical sort (LiHV or LiPo). You’ll be able to study extra about collection charging on this tutorial: https://oscarliang.com/serial-charging/

31mm Propellers for 65mm Whoops

Though most 31mm props are for motors with 1mm shaft, it’s greatest if you happen to verify earlier than ordering, typically motors may have 1.5mm shafts.

40mm Propellers for 75mm Whoops

That is a number of the greatest performing props available on the market with an awesome stability between energy and effectivity. Ensure to pick out the appropriate shaft diameter to match the motors.

Motors

It’s a pattern in tiny whoop motors to make use of greater KV motors (corresponding to 25,000KV to twenty-eight,000KV), tri-blade propellers with an ultralight construct (round 17g-18g). In a nutshell, greater KV means the motor will spin sooner when apply the identical voltage. See this put up for a extra detailed clarification: https://oscarliang.com/motors/#KV

For bi-blade propellers you want excessive RPM to unleash the need energy, sometimes pairing them with motors within the 28,000 to 32,000 KV vary offers nice end result.

Whereas skilled pilots can undoubtedly harness the complete potential of excessive KV motors, learners and intermediate flyers would possibly discover them too aggressive. As a substitute of utilizing low KV motors, I’d advocate beginning with a minimal of 26,000 KV motors after which cap the throttle or motor outputs to tame the facility if needed (you are able to do this both within the radio or Betaflight settings). With this methodology, even much less skilled pilots can regularly construct up their abilities to flying greater KV motors whereas having the flexibleness to regulate their energy.

For 65mm whoops, 0702 is a well-liked motor dimension, select between 26000KV and 30000KV relies on your propeller selection. For 75mm whoops, 1002 is a good motor dimension. For heavier builds with digital VTX’s, take into account even larger 1102 motors.

1002 is nice for analog whoops, and

Flight Controllers

VTX Antenna

TrueRC Singularity 5.8GHz Antenna with Quick U.FL

Most BNF Tiny Whoops include a easy whip antenna (linear polarized dipole antenna). They’re okay, however upgrading to the TrueRC Singularity Antenna affords noticeable efficiency enchancment whereas solely including half a gram of additional weight. If you’re combating video sign when flying indoor, it’s best to take into account upgrading to a round polarized antenna. I defined why round polarized antenna are higher for FPV than linear polarized antennas right here.

ExpressLRS Receivers

Left: ceramic antenna; Proper: flat antenna

ExpressLRS has emerged as one of the best radio management hyperlink for Tiny Whoops for quite a few causes. Firstly, it’s open-source, making it available and adaptable. This characteristic has made it simple for producers to include it into their flight controllers.

Moreover, ExpressLRS affords wonderful vary and penetration, outperforming many opponents out there (corresponding to Frsky D8/D16). Additionally telemetry is totally supported in ExpressLRS. Admittedly, it may be considerably tough to arrange initially for some customers, however as soon as mastered, its efficiency and flexibility make it definitely worth the studying curve.

Many new tiny whoop flight controllers provide built-in ELRS receiver, but when not you can even hook up an exterior ELRS receiver if there’s a spare UART. The RX could be very light-weight, and the antenna is compact and doesn’t require mounting. Ensure to get those with ceramic antenna (or flat antenna) for house saving.

Utilizing Throttle Expo for Indoor Flights

To make your drone simpler to regulate when flying indoor, think about using some throttle expo.

Throttle Expo refers to exponential throttle curve changes, permitting extra exact throttle management in tight areas, particularly when most whoops include highly effective high-KV motors lately.

With high-KV motors, there’s an inclination to lose important throttle decision, which may make exact management difficult. However when flying indoors, you’re often hovering or cruising round 30-35% throttle. Making use of 20-30 throttle expo round this throttle worth could make management extra exact and simpler.

What’s the Greatest DJI O3 Tiny Whoop?

Initially, the DJI O3 Air Unit, whereas a marvel in FPV expertise, introduces important weight constraints. That is notably problematic for drones designed to excel in tight indoor areas.

Whereas there are pilots showcasing their talent with 85mm whoops in cramped quarters, such feats are extra the exception than the rule. For almost all, a 65 or 75mm whoop offers the agility and security wanted for indoor flying. Nonetheless, by the point we scale as much as an 85mm drone, the added velocity and weight will trigger extra injury whenever you crash.

For those who insist on flying an DJI O3 drone indoor, I’d take into account one of many 75mm whoops, such because the BetaFPV Pavo Pico or Flywoo Flylens 75. However I discovered even these drones are a bit too heavy for flying indoor safely and comfortably.

Walksnail affords mild weight 1S VTX that’s far more appropriate for indoor mild weight tiny whoops, however they endure from untimely shutdown when voltage drops under 3.3V which could not be splendid for some individuals.
