Dry weight refers to the total weight of the drone without the battery. Here are the definitions of the terms used in the lookup table.

What’s a Tinywhoop?

Whoops or Tiny Whoops are small palm sized FPV drone with propeller guards or ducts, typically weighing around 20-40 grams. It’s known for its compact, enclosed propeller design, making it safe and suitable for indoor flying. Tiny Whoops are equipped with tiny, brushed or brushless motors and a small camera and video transmitter, providing a live video feed to the pilot’s goggles. They are popular for racing in tight, indoor spaces and for FPV beginners due to their durability, ease of control, and relatively low cost. Their small size and maneuverability make them ideal for navigating challenging courses or small, cluttered environments.

What’s a Freestyle FPV Drone?

A freestyle drone is a type of FPV drone optimized for agility, maneuverability, and creative flight. Unlike racing drones, which are built for speed and precision on a track, freestyle drones are designed for performing aerial acrobatics, flips, and complex maneuvers in open environments. They often have powerful motors and responsive controls to execute intricate flight patterns and tricks. Freestyle drones typically carry action cameras such as GoPro to capture dynamic, often acrobatic footage from the pilot’s perspective. Durability is also a key feature, as these drones frequently undergo rough landings and crashes during stunts. Freestyle flying emphasizes personal style, fluidity, and the art of aerobatic flight.

What’s a Long Range FPV Drone?

long range FPV drone is designed for extended flight distances, often exceeding several kilometers. These drones prioritize efficient power consumption, stable flight characteristics, and reliable communication systems over speed or agility. Equipped with large Li-ion battery packs and efficient propulsion systems, it’s possible to get 20 minutes, 30 minutes or even longer flight time. With advanced GPS capabilities, long-range drones can cover vast areas, making them ideal for exploration or aerial photography. They often feature robust radio equipment to maintain a strong connection over long distances and may incorporate fail-safe mechanisms like return-to-home functions to ensure safe recovery. The focus is on endurance and reliability, rather than speed or acrobatic capability.

What’s a Racing FPV drone?

Iflight Mach R5 Hd Bnf Racing Drone

A racing FPV drone is designed for high-speed competition, emphasizing agility, speed, and responsive control. Unlike freestyle drones, which are built for acrobatics and aerial stunts, racing drones prioritize compact, streamlined frames and lightweight construction for maximum velocity and maneuverability in races. Differing from long-range drones, which are optimized for distance and endurance, racing drones focus on short, intense bursts of speed in confined courses. Unlike cinewhoop-style drones, known for stable, smooth footage in cinematic productions, racing drones lack heavy camera gear, trading off filming capabilities for swift, agile flight dynamics essential in competitive racing scenarios.

What’s a Cinewhoop?

A Cinewhoop is a type of quadcopter specially designed for capturing cinematic footage. Characterized by its compact size and unique ducted propeller design, a cinewhoop offers stable, smooth flight, making it ideal for navigating tight spaces and intricate environments. Unlike traditional racing or freestyle drones, which prioritize speed and agility, cinewhoops focus on steady, controlled movements to produce high-quality video. They often come equipped with HD cameras like GoPro. Their ducted fans not only provide safety by shielding the propellers but also enhance flight stability, making cinewhoops popular for indoor filming and close-up shots in complex settings.

What’s an Ultralight FPV Drone?

An ultralight FPV drone, commonly known as a “toothpicks“, is a class of extremely lightweight and compact drones designed for agility and speed. Typically weighing less than 250 grams, these drones bypass certain regulatory constraints. Toothpicks are characterized by their minimalist frame design, small brushless motors, and simplified electronic components. Despite their small size, they offer a powerful flight experience with responsive controls, making them ideal for freestyle flying in intricate environment and popular among experienced pilots for fun, acrobatic flying.


I hope this lookup table has provided valuable guidance in selecting the appropriate motor size, propeller size, KV, and LiPo cell count for your next drone build. Remember that these are merely suggestions, and there’s always room for experimentation to find the perfect combination for your specific applications and flying style. Happy building and flying!

I’m flying 3.6 inch with 6S 2750Kv dry weight 340g on DOGCON 1100mha(+180g) and 1380(+210g) mha.
Is the right config ? ( Speedybee V4 55A + ECS)

Oscar 20th March 2024 - 4:26 pm

Sounds a bit heavy for a 3.5″ class. Mine with DJI O3 weighs around 350g including battery and that’s not the lightest setup either: https://oscarliang.com/volador-vx3-5-o3/

For 3.5″ maybe 550-650mah batteries are more suitable.

Use the Mini Stack, which could save you some weight – you don’t need that high amp rating anyway: https://oscarliang.com/speedybee-f405-mini-fc-stack/

Ajay n m 31st October 2023 - 1:25 pm

Hi oscar I just wanted to ask what motor would be good for my build . 5inch freestyle 600 grams twin blade props 4200 mah milocel 3s battery (3*4200) . The battery itself is around 300 grams so what would u suggest

Dodi Rustandi 14th September 2023 - 8:41 am

hai oscar how about 1404 motor with KV 4500 . i want to use frame diatone roma L4 and carrying runcam thumb pro with caddx nebula pro. which better using 4s lion battrey or 3s lion battrey ?

Oscar 14th September 2023 - 5:05 pm

That motor KV might be too high for 4S.

Seth 29th August 2023 - 1:18 am

Could you please include motor sizes and kv for a 4s and 6s 3.5″ cinewhoop?

MatCron 8th July 2023 - 8:51 pm

Think that for Li-Ion on a 7″ Long Range you should change to 4000-8000

_nn 28th April 2023 - 2:33 pm

community need an update to this priceless resource :)

Oscar 28th April 2023 - 2:45 pm

have things changed much recently? :)

Pineapples 23rd November 2023 - 3:47 pm

do you have a 3.5 4s and 6s recommendations

Jayson 4th August 2022 - 5:46 pm

This list holds immense value for those that don’t know the math to calculate what should be used. While it’s somewhat incomplete, it’s still good enough I’m coming here at least twice a month to study it to get a stronger idea of what goes with what.

Many thanks!

Oscar 5th August 2022 - 12:24 pm

Thanks! Let me know if there’s any missing quad/motor size I should add.

bhavani prasad daram 26th May 2022 - 5:33 am

hey oscar!
can you provide the calculative approach to select motor,propeller aand battery based on weight or thrust.

Jose Romulus Rebusora 8th August 2021 - 12:36 pm

Teach me how to fpv freestyl

Malcolm 4th April 2021 - 10:04 am

Hi Oscar
I would very much like to build a larger quad than those listed. Maybe 14″/15″ props for: Range/Flight Time, Stability as a camera platform, and Slower rotating props for noise/annoyance reduction.
The insane (YouTube: ‘TBS Discovery Pro on Steroids !’ being along the right lines. but very expensive. :)
Have you, or is there existing, a Motor/Prop chart for these larger Quads or any pertinent advice,
existing articles not being very comprehensive, or sometimes somewhat contradictory ?


Oscar 4th April 2021 - 5:13 pm

Multirotor this big isn’t very popular. main stream builds are below 7″.
I don’t have experience with 14″/15″ sorry.

Scott A Abramczyk 2nd April 2021 - 3:53 pm

No such thing as a 4S, 7-in freestyle?

Cédric 28th March 2021 - 10:14 am

Hi Oscar !
Just a little question : How a freestyle 6” quad (150-250g according to the lookup table) can be lighter than a freestyle 5” quad (250-450g ) ?
Tank you for your answer !
Happy flying

Oscar 28th March 2021 - 1:19 pm

sorry copy and paste error.

Jason 11th December 2022 - 10:33 am

Hi Cedric, whilst we are correcting typos, shouldn’t we make certain to spell words correctly? (ie) “Tank you for your answer.” ☝️🤦

Carlos 17th March 2021 - 10:39 pm

This is a great compilation, thanks!
Based on these, some nice trends on power-to-weight and disk loading could be set, with just a few more figures

Daniel 25th January 2022 - 10:47 pm
