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 normally function on 1S or 2S LiPo batteries. Tiny Whoop is a trademark by a US-based firm that popularized such a micro drones, so folks within the interest merely name all these small drones “Tiny Whoops”. These reasonably priced, easy-to-control FPV drones are excellent for indoor flying and can be flown outside in wind-protected areas. Their ducts guarantee security and scale back injury upon crashes.

Greatest 65mm Tiny Whoops

These 65mm Tiny Whoops are small, comparatively quiet, and simple to manage, making them one of the best whoops for indoor flying. A couple of bind and fly fashions stand out resulting from their superior efficiency, sturdiness and worth.

Greatest 75mm Tiny Whoops

If you’re searching for a extra highly effective whoop, or maybe one thing that may even fly outside, 75mm whoops are a more sensible choice than 65mm. There are additionally extra choices relating to HD Digital FPV methods.

Wheelbase: 65mm vs 75mm

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

Wheelbase refers back to the dimension of the body, which is the gap between two diagonal motors. For tiny whoops sometimes 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 in style alternative for flying at residence since they’re additionally barely smaller. However, the 75mm whoops provide better energy resulting from their bigger propeller and batteries. Some may discover them tougher to manage than the 65mm however they’re extra versatile and sooner.

For those who’re undecided between 65mm and 75mm whoops, 75mm usually presents longer flight instances, sooner speeds, and higher stability for outside flying. Nonetheless, 65mm whoops are extra agile and might navigate smaller gaps. Some racing occasions solely allow 65mm whoops, so take this into consideration should you’re severe about racing.

Brushed Motors or Brushless Motors

Tiny Whoops make the most of two kinds 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 varieties for a tiny whoop was more difficult. Nonetheless, with the introduction of efficiency options reminiscent of RPM filter and 48kHz assist in BLHeli_S, brushless motors have turn out to be the clear alternative. These days, it’s uncommon to discover a tiny whoop utilizing brushed motors.

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. Sometimes, 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 superb for informal indoor FPV flying. However, 2S whoops are extra highly effective and extra fitted to outside flight in calm climate or for lifting heavier payloads, reminiscent of higher cameras or FPV methods. Nonetheless, they is likely to be tougher to fly indoor in tighter areas.

LiPo Battery Connectors

As examined, BT2.0 connector outperforms the PH2.0 connector by offering stronger energy and barely longer flight instances. This is because of its decrease resistance and fewer voltage drop underneath load. You must use BT2.0 at any time when you may.

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

That stated, PH2.0 connectors are purposeful and enough for on a regular basis flying, and batteries with such a connector are extra available. It’s important to decide on a connector sort earlier than bulk buying LiPo batteries to make sure they’ve matching connectors.

A30 is a brand new connector made by GNB. It has related efficiency to BT2.0, however not fully suitable with BT2.0.

Important Equipment and Components

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

Battery Issues

Voltage: LiHV vs LiPo

Most tiny whoops make the most of LiHV batteries for greater energy and capability at a decrease weight, whereas additionally being suitable with LiPo batteries. LiHV batteries needs to be your default choice.

Connectors: BT2.0 vs A30 vs PH2.0

Batteries connect with your tiny whoop by way of a connector. Nearly all 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.

Word that you need to use A30 batteries with BT2.0 connectors on the quad, You may be capable of use BT2.0 batteries with A30, however you must plug it in forcefully which could injury the plastic over time.

Cell Varieties

For those who’re centered on efficiency, contemplate 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). Different corporations, like WeBleedFPV and TinyWhoop, rebrand their batteries utilizing the identical cells. The remainder in the marketplace 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 absolute best efficiency, squared cells are preferable.

So why aren’t folded cells utilized in bigger batteries? Past a sure capability threshold, reminiscent of 500mAh, the cell dimension is ample for conventional cell varieties 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 searching for flight time at comparatively gradual velocity, it is 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 vital 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 mainly 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 completely different voltage you may nonetheless join them to the board, the charger will steadiness 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 should you affirm earlier than ordering, typically motors might have 1.5mm shafts.

40mm Propellers for 75mm Whoops

That is a few of the greatest performing props in the marketplace with an important steadiness between energy and effectivity. Be certain to pick the best shaft diameter to match the motors.

Motors

It’s a development in tiny whoop motors to make use of greater KV (reminiscent of 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

However you might want to pair the best propellers to get essentially the most out of it. I’ve discovered that pairing motors of this KV with Gemfan bi-blade propellers results in sensible outcomes. These are arguably among the best Tiny Whoop propellers on the market. For bi-blade propellers you want excessive RPM to unleash the will energy, sometimes pairing them with motors within the 28,000 to 32,000 KV vary offers nice outcome.

Whereas skilled pilots can undoubtedly harness the complete potential of excessive KV motors, newbies and intermediate flyers may discover them daunting. As an alternative of shopping for low KV motors, I’d suggest beginning with a minimal of 26,000 KV motors after which utilizing throttle or motor output limits to tame the ability if obligatory. With this technique, even much less skilled pilots can step by step acclimate to greater KV motors whereas having the flexibleness to manage their energy.

Do be aware that it’s normally not advisable to restrict the motor under 65 to 70 p.c as this might trigger some throttle decision points.

1002 or 1102 motors for 75mm whoops? 1002 is nice for analog whoops, and for heavier digital VTX’s, you most likely wish to use the larger 1102 motors.

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 presents glorious vary and penetration, outperforming many rivals available in the market (reminiscent of Frsky D8/D16). Additionally telemetry is absolutely supported in ExpressLRS. Admittedly, it may be considerably difficult 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 it’s also possible to 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. Be certain 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 an inclination to lose vital throttle decision, which may 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 start, the DJI O3 Air Unit, whereas a marvel in FPV know-how, introduces vital 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 gives 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 while you crash.

For those who insist on flying an DJI O3 drone indoor, I might contemplate 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.

Walksnail presents mild weight 1S VTX that’s far more appropriate for indoor mild weight tiny whoops.
