What’s a Tiny Whoop?

A Tiny Whoop is a small indoor FPV drone that includes 31-40mm propellers, protecting propeller guards (also referred to as ducts), and 65mm or 75mm body wheelbases. They normally 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 excellent for indoor flying and can be flown outside 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 manage, making them the most effective whoops for indoor flying. Just a few bind and fly fashions stand out attributable to their superior efficiency, sturdiness and worth.

Greatest 75mm Tiny Whoops

If you’re in search of a extra highly effective whoop, or maybe one thing that may even fly outside, 75mm whoops are a better option than 65mm. There are additionally extra choices in the case of HD Digital FPV programs.

Wheelbase: 65mm vs 75mm

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

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

The 65mm whoops are the basic, they’re extra agile and simpler to manage, and the extra well-liked selection for flying at dwelling since they’re additionally barely smaller. Alternatively, the 75mm whoops supply larger energy attributable to their bigger propeller and batteries. Some may discover them tougher to manage than the 65mm however they’re extra versatile and sooner.

Should you’re undecided between 65mm and 75mm whoops, 75mm typically provides longer flight instances, sooner speeds, and higher stability for outside flying. Nonetheless, 65mm whoops are extra agile and may navigate smaller gaps. Some racing occasions solely allow 65mm whoops, so take this into consideration in case you’re severe about racing.

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 equivalent to RPM filter and 48kHz help in BLHeli_S, brushless motors have grow to be the usual whereas brushed whoops have grow to be out of date.

Battery Cell Rely: 1S vs 2S

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

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

1S whoops are lighter, quieter, safer, and trigger much less injury throughout crashes, making them best for informal indoor FPV flying. Alternatively, 2S whoops are extra highly effective and extra suited to outside flight in calm climate or for lifting heavier payloads, equivalent to higher cameras or FPV programs. Nonetheless, they could be tougher to fly indoor in tighter areas.

LiPo Battery Connectors

As examined, BT2.0 and A30 connectors are the best selections for tiny whoops by offering stronger energy and barely longer flight instances. This is because of their decrease resistance and fewer voltage drop beneath load. Whereas PH2.0 connectors are purposeful and sufficient for on a regular basis flying, it’s best to use BT2.0 or A30 every time you possibly can and keep away from PH2.0.

In case your whoop have a PH2.0 connector, you possibly can simply change it with a BT2.0 connector if you know the way 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 Components

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

Battery Issues

Voltage: LiHV vs LiPo

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

Connectors: BT2.0 vs A30 vs PH2.0

Batteries hook up with your tiny whoop through a connector. The vast majority of tiny whoops have a PH2.0 connector, so make sure the batteries you buy are suitable. Be careful for battery connector, A30/BT2.0 usually are not suitable with PH2.0.

Notice that you should use A30 batteries with BT2.0 connectors on the quad, You may have the ability to use BT2.0 batteries with A30, however it’s important to plug it in forcefully which could injury the plastic over time.

Cell Varieties

Should you’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 the most effective of my data, Tattu is the one producer producing folded cells (their 1S 300mAh and 450mAh HV lineup) in 2023, however that would change sooner or later. Different firms, like WeBleedFPV and TinyWhoop, rebrand their batteries utilizing the identical cells. The remaining available on the market are primarily rolled cells.

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

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

Efficiency

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

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. In contrast to parallel charging, with collection charging, even when the batteries have very totally different voltage you possibly can nonetheless join them to the board, the charger will stability the voltage throughout charging. All batteries have to be of the identical sort (LiHV or LiPo). You possibly can 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 finest in case you affirm earlier than ordering, typically motors may have 1.5mm shafts.

40mm Propellers for 75mm Whoops

That is among the finest performing props available on the market with an awesome stability between energy and effectivity. Ensure that to pick the correct shaft diameter to match the motors.

Motors

It’s a pattern in tiny whoop motors to make use of greater KV with tri-blade propellers, equivalent to 25000KV and 26000KV, as they provide you extra energy. In a nutshell, greater KV means the motor will spin sooner when apply the identical voltage. See this submit for a extra detailed rationalization: https://oscarliang.com/motors/#KV

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

Whereas skilled pilots can undoubtedly harness the total potential of excessive KV motors, newbies and intermediate flyers may discover them too aggressive. As an alternative of utilizing low KV motors, I’d suggest beginning with a minimal of 26,000 KV motors after which cap the throttle or motor outputs to tame the facility if mandatory (you are able to do this both within the radio or Betaflight settings). With this methodology, even much less skilled pilots can steadily construct up their expertise to flying greater KV motors whereas having the flexibleness to manage their energy.

For 65mm whoops, 0702 is a well-liked motor measurement, select between 26000KV and 30000KV is determined by your propeller selection. For 75mm whoops, 1002 is a superb motor measurement. For heavier builds with digital VTX’s, take into account even greater 1102 motors.

1002 is nice for analog whoops, and

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 provides 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 has emerged as the most effective 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 straightforward for producers to include it into their flight controllers.

Moreover, ExpressLRS provides glorious vary and penetration, outperforming many opponents available in the market (equivalent to Frsky D8/D16). Additionally telemetry is absolutely 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 well worth the studying curve.

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

Utilizing Throttle Expo for Indoor Flights

To make your drone simpler to manage 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 today.

With high-KV motors, there’s a bent to lose important throttle decision, which might make exact management difficult. However when flying indoors, you’re normally 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?

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

Whereas there are pilots showcasing their ability 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 pace and weight will trigger extra injury while you crash.

Should you 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 provides 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 best for some individuals.
