What FPV Motor Sizes Do I Need for My Quad?

Considerations for FPV Motor Sizes When Choosing a FPV Motor

Choosing the right FPV motor sizes is essential for optimizing your FPV drone’s performance, whether you’re aiming for speed, agility, or stability. FPV motor sizes directly impact the drone’s power, efficiency, and overall flight characteristics. Understanding the differences between various motor sizes will help you make an informed decision that aligns with your specific flying needs, from racing to freestyle or cinematic flying.

The right FPV motor sizes depend on your frame and propeller size:

• 3″ drones → 1404–1505 motors
• 5″ freestyle/racing drones → 2207 or 2306 motors
• 7″ long-range drones → 2507–2806.5 motors

In short: smaller motors (06xx–14xx) suit micro builds and whoops, while mid-size motors (22xx–23xx) power most 5″ FPV drones, and larger motors (25xx–28xx+) are for long-range or heavy-lift platforms. Matching motor, prop, and battery ensures efficiency, thrust, and flight performance.

This guide explains how FPV motor sizes relate to frame, prop, KV, and battery voltage—so you can confidently pick the best FPV motor for racing, freestyle, cinewhoop, or long-range flying.

What is the Size of A Drone Motor?

What Do FPV Motor Sizes Mean? (Drone Motor Sizes Explained)

In FPV, motor size is not just a number—it describes the physical dimensions of the stator, which is the part that actually generates power. Understanding motor size helps you avoid mismatched builds and choose motors that truly fit your flying style, whether it’s freestyle, racing, cinematic, or long-range.

FPV Drone Motor Components

There are two major components to an FPV drone motor: rotor and stator.

• Rotor – the rotating component with the magnets arranged in a radial manner
• Stator – the portion with electromagnets that is non-rotating

FPV Drone Motor Sizes Explained

A group of four numerals, such as 2207, 2306, or any other number, represents the size of a specific motor model. It indicates the rotor’s height and diameter in millimeters (mm).

• First two digits → stator diameter (in millimeters).
• Last two digits → stator height (in millimeters).

For example:

• 2207 Motor: 22 represents the stator width (or stator diameter), 07 represents the stator height, both measured in millimetres.
• 2306 Motor: 23 represents the stator width (or stator diameter), 06 represents the stator height, both measured in millimetres.

• length of rotor shaft: 30mm±5
• inner diameter: 16mm±05
• outer diameters: 29.31mm±2

Compatibility of FPV Motor Sizes with Other Component Sizes

In FPV drone builds, motor size, propeller size, and frame wheelbase are tightly linked. If one of them is mismatched, your quad will either underperform or risk hardware failure. The frame sets the maximum propeller clearance, the propeller determines the torque demand, and the motor stator size must provide enough thrust to spin those props efficiently.

Rule of thumb:

• Frame wheelbase decides the maximum prop size.
• Prop size dictates the required motor torque.
• Motor stator size should be chosen to balance efficiency, power, and durability for that prop/frame combo.

Pro Tip:

• Using too small a motor on a large prop (e.g., 1407 on 5″) causes overheating & ESC overload.
• Using too large a motor on a small prop (e.g., 2806.5 on 4″) wastes efficiency and feels sluggish.
• Always leave at least 10–15 mm prop tip clearance on the frame to avoid vibration and air turbulence.

Motor Size and Frame Size

• 65–85mm tinywhoop frame → 0702 – 1103
• 3″ frame → 1203 / 1404
• 4″ frame → 1404 / 1505
• 5″ frame → 2207 / 2306
• 7–8″ frame → 2507 / 2806+
• 9-10″ frame → 2810 – 3214

Motor Size and Propeller Size

• Larger motors can spin larger or higher-pitch props
• Smaller motors struggle with heavy prop loads and overheat faster

Motor Size (Stator)	Typical Drone Type	Safe Prop Size	Common Pitch Range	Notes
0702	Tinywhoop (65mm)	31–35mm (1.2–1.4″)	1.5–2.0	Ultra-light indoor whoops, very low torque
0802	Tinywhoop (65–75mm)	35–40mm (1.4–1.6″)	1.9–2.3	Most popular indoor FPV motor
1002	75mm Tinywhoop	40mm (1.6″)	2.0–2.5	Better punch, still indoor-safe
1103	Outdoor Whoop / Toothpick	2–2.5″	2.5–3.5	Strong torque, handles wind better
1203–1404	2.5–3″ builds	2.5–3″	2.5–3.5	Lightweight freestyle
1505–1606	3.5–4″ builds	3.5–4″	3.0–4.0	Mid-size freestyle
2207	5″ Racing / Freestyle	5″ tri-blade	3.5–4.6	High RPM, race-focused
2306	5″ Freestyle	5″ tri-blade	3.0–4.3	Balanced torque & efficiency
2407–2507	6″ builds	6″	3.0–4.0	Heavy freestyle
2806 / 2808	7–8″ Long Range	7–8″ bi/tri-blade	3.0–4.0	Cinematic & LR
3110 / 3212	9–10″ Long Range / Cinematic	9–10″ bi-blade	2.5–3.5	High torque, low RPM efficiency

FPV Motor Size and ESC & Battery

• Bigger motors draw more current → need higher-rated ESCs
• 6S setups favor larger stators with lower KV
• 4S setups favor smaller stators with higher KV

In FPV builds, motor size sets the ceiling for how aggressive the rest of the setup can be.

Why FPV Motor Size Matters So Much?

In FPV motor sizes, even a small change—such as moving from a 2205 to a 2207—can completely change how the drone behaves on the sticks. That’s why serious builders always look at drone motor size comparison, not just KV ratings.

In simple terms: FPV Motor size determines how efficiently a motor converts battery power into usable thrust and control.

How Stator Size Affects Motor Performance

The stator is the heart of the motor. Its dimensions (diameter × height) define torque output, throttle response, efficiency, and thermal behavior.

Key Performance Impacts of Stator Size:

• Torque output
  Larger stator volume = stronger magnetic field = more torque. This allows the motor to spin larger or higher-pitch props without bogging down.
• Throttle response
  Motors with more torque reach the target RPM faster. This matters in drone racing, where split-second acceleration out of corners wins races.
• Efficiency under load
  A stator that’s too small for the prop will overheat and waste energy. A properly sized stator stays cooler and maintains consistent performance.
• Thermal stability
  Bigger stators can absorb and dissipate heat better, reducing the risk of demagnetization or winding damage during aggressive flying.

This is why experienced pilots rarely choose motors by KV alone. FPV motor sizes must match prop size, battery voltage, and flight style as a system.

Taller Stator vs Wider Stator

Because the mass of a wider motor is farther from the rotational axis, it takes more energy to alter the RPM when the motor is spinning, resulting in greater inertia. Therefore, even if they have the same stator volume and torque output, broader and shorter motors are typically less responsive than narrower and taller motors. Smaller magnets on the motor bell of wider and shorter motors can also lower the motor’s output.

However, because they have more surface area on top and bottom, wider motors provide better cooling. Motor performance is highly dependent on temperature. A motor’s capacity to produce magnetic flux diminishes with temperature, which affects torque output and efficiency.

A motor stator’s width and height essentially serve as a compromise between cooling and responsiveness. Depending on how you fly, you should make a choice. For example, bigger stator motors may provide greater cooling for slow cinewhoops hauling a heavier GoPro. Taller stator lengths may be preferable for sports drones or racing drones that react quickly. Larger stators also make it possible for larger bearings, which can enhance performance, lifespan, and smoothness.

Not necessarily are larger stators better. For instance, 2207 motors can manage standard 5” propellers. However, utilizing considerably heavier 2506 motors with the same KV may not yield any appreciable advantages since they would still generate the same thrust with the same propellers, or the weight may even result in less responsiveness. Higher KV motors are an option if you want to increase performance without gaining weight. However, because of the higher torque requirements, the 2506 motor in this case would probably perform better with 6” propellers than the 2207.

In short:

Taller Stator (e.g. 2207 vs 2205)

Characteristics:

• Higher torque per amp
• Faster transient response
• Better control at low and mid throttle
• Slightly heavier rotor

Best for:

• FPV racing
• Tight technical tracks
• Pilots who want instant throttle authority

A taller stator increases the magnetic interaction length. This allows the motor to “grab” the rotor harder, making it feel more locked-in and predictable during rapid throttle changes.

Wider Stator (e.g. 2306 vs 2207)

Characteristics:

• Smoother power delivery
• Better sustained RPM
• Higher rotational inertia
• Slightly slower throttle changes

Best for:

• Freestyle
• Cinematic FPV
• Long, flowing lines

The following content will describe in detail how to choose the FPV motor size.

How to Choose the Right Size Motor for Your Build?

To ascertain the optimal drone motor sizes for your FPV drone, proceed as follows:

Step 1: Determine Your Frame Size

Start with your frame size, usually defined by the motor-to-motor diagonal distance (wheelbase) or by the prop size the frame supports.

Your frame directly limits:

• Maximum propeller diameter
• Motor mounting pattern
• Total weight and thrust requirements

For example:

• 75–85mm frames → Tinywhoop (31–40mm props)
• 120–140mm frames → 3-inch props
• 210–225mm frames → 5-inch props
• 280mm+ frames → 7–10 inch long-range builds

Once the frame size is fixed, everything else must match it.

Step 2: Match the Propeller Size

Propeller size is dictated by the frame’s prop clearance and flying purpose.

• Smaller props (31–40mm): lightweight, fast response, indoor flying
• Medium props (3–5 inch): freestyle, racing, balanced performance
• Large props (7–10 inch): long range, efficiency, payload carrying

Using props that are too large or aggressive for the motor will dramatically increase current draw and heat.

Step 3: Select the Right Motor Size and KV

You can determine the suitable FPV motor size by determining the frame size. The prop size is limited by the frame size, and in order to generate thrust efficiently, each prop size requires a varied motor RPM. This is the application of motor KV. Verify the motors’ torque to ensure they can turn the propeller of your choosing. One aspect of this is the stator size. Higher KV and bigger stator diameters frequently result in higher current draw.

Propeller size defines the load placed on the motor. The motor must have a stator size large enough to generate sufficient torque, along with a KV rating that keeps RPM within an efficient range.

• Smaller propellers (Tinywhoop, 2–3 inch) work best with smaller stators and higher KV, prioritizing fast response and low weight.
• Medium propellers (5 inch) require mid-size stators that balance torque and responsiveness, paired with moderate KV values.
• Large propellers (7–10 inch) need larger stators with lower KV to provide strong, sustained torque without overheating.

Step 4: Evaluate Torque Requirements

Torque is what actually turns the propeller. It mainly comes from stator volume.

General rule:

• Bigger props → larger stator volume
• Heavier drones → more torque required

However:

• Larger stators + higher KV = higher current draw
• More torque without proper cooling = overheating

This is why motor size must be balanced with prop choice and battery voltage—not chosen in isolation.

Drone Motor Sizes Chart:

Frame Wheelbase (mm)	Prop Size	Motor Size (Stator)	KV Range (Typical)	Battery (S)
65–85 mm	31–40 mm (1.2–1.6″)	06xx – 08xx	18,000–25,000 KV	1S
85–120 mm	2″–2.5″	11xx – 14xx	8,000–12,000 KV	2S–3S
120–140 mm	3″	14xx – 15xx	3,500–6,000 KV	3S–4S
155–180 mm	4″	16xx – 20xx	3,000–4,500 KV	4S
195–225 mm	5″	22xx – 23xx	1,700–2,800 KV	4S–6S
250–270 mm	6″	23xx – 25xx	1,500–1,900 KV	4S–6S
300–330 mm	7″	25xx – 28xx	1,200–1,800 KV	6S
360–390 mm	8″	28xx – 30xx	900–1,200 KV	6S–8S
400–500 mm	9–10″	30xx – 35xx	800–1,000 KV	6S–8S

Matching Drone Motor Size to Propeller Size

The size of your propellers should match the motor size for optimal efficiency and performance.

• Larger motors generally work better with larger props (e.g., a 2207 motor with 5-inch props), providing more thrust and stability.
• Smaller motors are suited to smaller props (e.g., a 1404 motor with 3-inch props), offering faster response times but less overall thrust.

Choosing the right combination ensures your drone performs as expected, without overloading the motors or underutilizing their potential.

Battery Compatibility and Voltage Selection

Voltage Considerations (3S, 4S, 6S): The voltage of your battery (measured in S, where each cell is 3.7V) significantly impacts motor performance. Higher voltage (e.g., 6S) can produce more power and efficiency, but requires motors with a lower KV rating to maintain balance and avoid overheating. For instance, a 6S setup might pair well with a 1700KV motor, while a 4S setup could use a 2300KV motor for similar performance.

Typical pairings:

• 4S → ~2300–2600KV (5-inch freestyle/racing)
• 6S → ~1600–1900KV (5-inch performance builds)
• 6S long range → ~1200KV or lower

Ensuring your drone motor’s KV rating matches your battery voltage will help prevent issues like excessive heat, poor efficiency, or even motor burnout.

Best Motor Sizes for Micros:

TinyWhoops: 

65mm:

For a micro drone of this motor size, often classified as a tiny whoop, the perfect FPV motor size varies depending on the application of your drone.

• If weight is your priority, a 0702 motor will fit your needs with it also being zippier and coming in a large range of ultrahigh KVs.
• If torque and power at the cost of efficiency are your priority, for a 65mm, 0802 is the best choice.
• With 0603 being for the chunkier builds like a Meteor 65 pro.

For these drones, the KV options are vast, ranging from 19,000 up to 32,000, so for more control, choose a lower KV, but for raw thrust, high KV is the only way. The MEPS 0802 motors are a great choice for this.

Optimal KV Range:

• 1S: 23,000-30,000 KV for triblade props, 30,000+ KV for two-blade props

75mm:

For a larger micro drone with a more efficient and powerful performance, 75mm with 1s is the best as it’s good for indoors and can fly outdoors with ease while getting more flight time.

Motor Sizes: 0802, 1002, 1102, 1103

Optimal KV Range:

• 1S: 20,000-25,000 KV
• 2S: 12,000-14,000 KV
• 3S: 8,000-11,000 KV

Recommended Propellers: 40mm (1.6″) triblade or two-blade

In a 75mm light-weight build, 0802 with a KV ranging from 19,000 to 25,000 is more than enough for high performance and efficiency. If power is your true goal or you are using a 75mm frame with larger ducts, such as the Meteor 75 pro or the Fractal 75 pro max, a 1002 motor with the same KV range will work well at the cost of some weight and efficiency.

85mm:

These ducted whoops are truly no longer for indoor and are no longer outdoor rippers, mainly running 2s batteries with an XT30 connector. There are many different sizes for motors which can be employed, but the ideal ones used on most BNF drones are xx03, meaning something like a 1003, 1103, or 1203 will work fine with these larger whoops. The recommended KV is from 10,000 to 14,000 max for 2s. The MEPS 1103 motors are a great fit for this drone class.

Best Motor Sizes for Toothpicks:

2” 1s: A toothpick of these specifications will be using smaller motors for a lighter weight with motor sizes ranging from 1002 at minimum, with 1003 being on the high end. The recommended KV would be from 16,000 to 22,000 at the high end.

2” 2s: These toothpick drones are truly powerful and can cover a larger outdoor area. Motor recommendations range from xx2.5 to xx3, such as 1202.5 and 1003 motors. Use the same KV as the 85mm drones, which employ the same sized propeller. The MEPS 1103 motor is a great option for this size.

2.5”: These drones almost always use 2s and 3s, so for a build of this spec, larger motors must be used, such as xx03 to xx04, such as a 1203, 140,3 or 1104, and similar sizes. The recommended KV would be anywhere from 10,000 to 14,000 on 2s and 6,000 to 10,000 on 3s. The lower KV MEPS 1103 motor is a great option for 3s power.

Best Motor Sizes for Freestyle & Racing Flight:

Small Sized Drones：

3”: This is where drones start to leave the micro class as they grow larger and much more powerful. These drones commonly run on 3s-4s batteries and use larger motors. The recommended drone motor size would be something like an xx04, such as an 1104, 1204 or 1304 motor. For 3s, the recommended KV would be anything from 4,000 and 7,000, and for 4s, anything from 3,000 to 6,000 should provide plenty of power for this class.

3.5”: This class of drones is the limit for a micro and these drones commonly use 4s-6s batteries. For FPV motor size, the recommended size for this class of large micros is xx04 motors, such as 1404,1504 and similar sizes. The recommended KV for 4s is 3,500 to 5,000 and for 6s, the recommended KV would range from 2,500 to 4,500. The MEPS 1404 motors would be a great choice with a build of this size for drone motor.

Medium Sized Drones:

4”- 4.5”: These drones are almost full-sized freestyle drones. They may be of similar size, but the performance is dramatically different, with the 4-4.5” drones being much lighter and nimble. The recommended FPV motor sizes for this frame would be xx04.5-xx05, such as a 2205 or 2304.5 motor. The recommended KV for 4s is 2,500-3,500, and for 6s, the recommended KV would be 2,200 to 3,300.

Full Sized Drones:

5”-5.5”: What size motor should I use for a 5-inch drone? A 5 inch FPV drone typically uses 2207 or 2306 motors with a KV rating between 1750KV-2400KV, depending on battery voltage and flight style. The 2207 motor is overall larger and gives more torque and thrust, while the 2306 motor is generally smoother and more efficient, due to the wider and shallower stator for better cooling. The recommended KV for 4s is 2,100-2,750, and the recommended KV for 6s would be 1,700-2,100.

5″ Racing Drone:

Motor Sizes: 2205, 2206, 2207, 2208, 2306, 2308

Optimal KV Range:

• 4S: 2,500-3,000 KV for racing applications
• 6S: 1,900-2,300 KV for racing applications

5″ Freestyle Drone:

Motor Sizes: 2206, 2207, 2208, 2306, 2307, 2308

Optimal KV Range:

• 4S: 2,300-2,700 KV
• 6S: 1,700-2,100 KV (Lower KV motors provide a smooth, predictable feel while maintaining good power efficiency)
• 8S: 1,500-1,700 KV

6”: This drone sits in the middle of a 5” freestyle drone and a 7” long range drone. A 6” drone is versatile as a cruiser and light freestyle drone, mainly used with 6s power. These drones use slightly larger motors with the recommended size being xx08, such as a 2308 motor. The recommended KV for 6s is anywhere from 1,300-1,800.

Motor Sizes: 2207, 2208, 2306, 2307, 2308, 2407

Optimal KV Range:

• 4S: 2,100-2,500 KV
• 6S: 1,500-1,900 KV

Best Size for Large Drone Motors

7 Inch Drone Motor

7-inch drone motors are commonly used for long-range FPV flights or efficient cruising, often equipped with high-capacity batteries to extend flight time. Compared to 5-inch and 6-inch drones, 7-inch builds require larger motors with higher torque to drive the longer propellers.

  • Ideal for long-range exploration, cinematic payloads, mapping, and industrial missions

For 9–10 inch drones, a reliable option is the T-Hobby V3115, offering strong torque output, excellent cooling, and stable performance for demanding long-range and cinematic builds.

Best Motor Sizes for Cinewhoops:

2”: This small indoor Cinewhoop uses the same-sized motors as the other 2” prop spinning drones, with the ideal motor size being xx03, such as 1003 and 1103. And the ideal KV is 10,000 to 14,000. A great choice is the MEPS 1103 motor.

Motor Sizes: 1003, 1103, 1203, 1303, 1404

Optimal KV Range:

• 2S: 7,500-15,000 KV
• 3S: 6,000-8,000 KV
• 4S: 5,000-6,000 KV

2.5”: This is the step up from the 2.5” Cinewhoop using a 4s battery, with it being one of the most versatile drones you can get. They do well both indoors and outdoors, with the recommended FPV motor size being xx04, such as 1404, and the recommended KV being 4,000-6,000. The MEPS 1404 motor is a great fit for this.

3”: This is a Cinewhoop to be mainly used outdoors in some larger indoor applications. The recommended FPV motor size would again be xx04, such as a 1504 motor. The recommended KV would be from 3,500-4,300 for 4s and 3,000-3,800 for 6s. The MEPS 1404 motors would work well on this build as well.

3.5”: This is a Cinewhoop for outdoor use with much better performance and efficiency than the others. The recommended motor size would be xx04-xx05.5, such as a 2004 or 2005 motor. The recommended KV for 4s would be 2,300-2,80,0 and 1,700-2,200 for 6s. The MEPS 2004 motors are a great option for a build like this.

FAQ

What’s a Brushless Motor?

What’s a Brushless Motor? Simply put, an FPV drone motor has no brushes, as the name suggests. The rotor and the stator are the two distinct parts that make up a brushless motor. The core component that the rotor is attached to is called the stator. The stator is composed of a network of radial electromagnets that, when a current flows through the windings, alternately turn on and off to create a momentary magnetic field. A set of permanent magnets housed in the rotor is positioned near the electromagnets of the semi-permanent stator. Rotation is produced by the stator and rotor magnets’ attractive and repulsive interactions. After the rotor is constructed, its shaft is placed into two ball bearings in the stator to keep the rotor rotating smoothly and linearly.

The brushless motor cannot be driven directly, even though it is powered by DC current. Rather than requiring brushes or a commutator, the brushless motor is directly connected to the control electronics. Because the rotor and stator do not come into direct contact, brushless motor longevity is exceptional. In terms of efficiency, the brushless motor outperforms the brushed motor as well. In applications requiring high power outputs and efficiency—such as tiny and micro multicopter applications—brushless motors are widely used.

Brushed vs Brushless Motor: What’s the Difference?

Typically, mini drones and lightweight configurations use brushed motors. Because of the brushes on its lower half, it may be powered directly by direct current DC; nonetheless, it is not very effective in scenarios when maximum power is required. Brushless motors, on the other hand, might be a better choice if you’re designing a racing drone, which will place a high demand on the motor because of its weight and capacity.

What Size Motor is a 5 Inch FPV Motor?

The 2207 and 2306 motor sizes are the most popular for 5-inch drones. While 2306 motors are renowned for their superior responsiveness, 2207 motors often offer more power. The common 16x16mm (M3) mounting style is used by many 5-inch drone motors, guaranteeing wide compatibility with the majority of frames.

2207 Motor VS 2306 Motor

• 2207: Delivers more torque and punch, with faster throttle response. Great for racing and aggressive freestyle.
• 2306: Smoother low-end control with better efficiency and cooling. Ideal for longer flight times or cinematic flying.
