If you are looking for a motor for a 5-inch or 6-inch FPV freestyle build, the motor size and KV rating can make a noticeable difference in how the quad feels in the air. The MEPS 2408 motor has gained attention for its strong torque, smooth performance, and durability. Designed with freestyle and cinematic pilots in mind, this motor provides an excellent balance between raw power and stable control.
In this review, we will take a closer look at the specifications, performance tests, flight experience, and overall value of the MEPS 2408 1900KV drone motor, and compare it with popular alternatives like 2207 and 2306 motors.
Unboxing and First Impressions
Upon unveiling the MEPS 2408, we’re greeted with a robust and meticulously designed motor. The package not only includes the motor but also a variety of accessories to ensure a seamless installation. Inside, you’ll find:
- A quality assurance card
- A moisture-absorbing gel bag
- An accessory bag containing: Two sets of screws (short and long), An aluminum nut for the shaft retainer, A metal ring and silicone spacer (or damper)
The attention to detail in packaging and the inclusion of essential accessories right out of the box is commendable.
Specifications and Features
The MEPS Space SZ 2408 motors come in two variants: 1900KV and 2500KV, catering to different power needs and preferences. The motor we’re focusing on today, the 1900KV, is particularly recommended for 5 and 6-inch quadcopters.
| Specification | Details |
|---|---|
| KV Rating | 1900KV/2500KV |
| Stator Size | 2408 |
| Weight | Approx. 36g (without wires) |
| Voltage Range | 4S–6S LiPo |

The 2408 stator size means this motor offers more torque compared to smaller options like 2207 or 2306, making it ideal for heavy props and aggressive freestyle flying.
Physical Attributes
- Weight: The motor itself weighs 39.5 grams, with the total assembly reaching around 40 grams when including the nut.
- Dimensions: Featuring a rotor diameter of 29.8mm and a height of 20mm, the total height comes to 34mm, with a shaft height of 14mm. These dimensions affirm the motor’s capability to handle substantial propellers efficiently.
Construction Quality
- The motor boasts a titanium shaft and is constructed from 60 82 series aluminum, ensuring both strength and lightweight performance.
- With N45 magnets and well-balanced components, the motor promises smooth operation and efficient power delivery.
- The stator measures 24mm in diameter and 8mm in height, aligning perfectly with the technical specifications.
How Does the SZ2408 1900KV Feel in Flight?
A larger stator does not automatically make a motor better. The important question is what the additional stator volume does for the actual flight experience.
Stronger Punch-Out Performance
The biggest reason to consider the SZ2408 is torque. When you pull the throttle aggressively after a dive or during a vertical punch-out, the motor needs to accelerate the propeller quickly. A higher-torque motor can feel more authoritative when the propeller is heavily loaded. This makes the SZ2408 particularly attractive for aggressive freestyle. Instead of optimizing only for the lowest motor weight, the design prioritizes a combination of torque, thrust, and control.
Better for Heavier Prop Loads
The SZ2408 is also useful when your build is carrying more weight or using a propeller with a higher aerodynamic load.
This can be valuable on:
- heavier freestyle builds
- 6-inch builds
- cinematic setups carrying additional equipment
- 5-inch quads tuned for aggressive throttle response
If your quad already feels sluggish when recovering from a dive or changing direction quickly, moving to a higher-torque motor can be more useful than simply choosing a higher KV motor.
Smooth Throttle Control
High peak thrust is only part of the equation. For freestyle, pilots also need predictable throttle response. The SZ2408 combines its 24×8mm stator with NMB bearings, N45SH magnets, a TC4 titanium alloy shaft, high-temperature copper windings, and a dynamically balanced rotor. The result is a motor designed not only for high output, but also for controlled power delivery during repeated throttle changes.
Flight Feel
On the field, the motor feels smooth and responsive. Pilots reported stable control during sharp maneuvers, with enough torque to recover quickly from dives and tricks.
Our tests with various propellers on a 6S battery setup demonstrated impressive results.
Notably, with HQ propellers, the motor achieved over 1800 grams of thrust, showcasing its high efficiency and power output.
Application and Suitability
The MEPS Space SZ 2408 motors are versatile, suitable for both 5 and 6-inch quadcopters. Their robust construction and excellent torque make them a perfect fit for freestyle and aggressive flight styles. Whether you’re building a quadcopter for racing or aerial photography, these motors offer the reliability and performance you need.
What Are the Main Advantages and Disadvantages?
Advantages
- Strong torque: The 24×8mm stator provides the torque-oriented character that makes the motor attractive for freestyle.
- High tested thrust: The motor reached 1882g per motor with an HQ Prop S5 under the stated test conditions.
- 5–6 inch versatility: The motor can be used across both 5-inch and 6-inch performance-oriented builds.
- Premium construction: The motor uses NMB bearings, a TC4 titanium alloy shaft, N45SH magnets, high-temperature copper windings, and a dynamically balanced rotor.
Disadvantages
- Heavier than smaller motors：At around 39.5g per motor, it is not aimed at ultra-light builds.
- Not the obvious racing choice：Racing pilots who prioritize minimum weight may benefit more from a smaller motor.
- Requires the right battery and prop combination：The 1900KV version makes the most sense in a 6S-oriented setup. Simply installing a larger motor without considering KV, battery voltage, propeller load, and ESC capacity will not automatically improve a build.
SZ2408 vs 2306 vs 2207: Which Motor Size Should You Choose?
| Motor Size | General Character | Best Use | Main Advantage |
| 2207 | Lightweight and responsive | 5″ racing / lightweight builds | Lower weight |
| 2306 | Balanced | 5″ freestyle | Good power-to-weight balance |
| 2408 | Higher torque | 5–6″ freestyle | Stronger torque and prop loading |
2207: Choose It for Lightweight Performance
A 2207 is a strong option when keeping the quad light is a priority. It makes particular sense for racing-oriented builds where acceleration, agility, and low overall weight are more important than running heavier propeller loads.
2306: The Balanced Option
A 2306 sits closer to the middle. For a conventional 5-inch freestyle build, it can provide a good balance between power, weight, and efficiency. If you already have a well-balanced 2306-powered quad and do not need additional torque, there may be little reason to change.
2408: Choose It for Torque
The SZ2408 becomes more interesting when you want:
- stronger punch-outs
- more torque
- better control with heavier props
- a more powerful feel on a heavier quad
- compatibility with both 5-inch and 6-inch performance builds
So the choice is not simply:
2408 = better
It is:
2408 = more torque-oriented.
SZ2408 1900KV vs 2500KV: Which One Should You Choose?
The SZ2408 is available in both 1900KV and 2500KV versions. The easiest way to decide is to start with your battery.
| SZ2408 1900KV | SZ2408 2500KV | |
| Recommended Battery | 6S | 4S |
| Motor RPM Character | Lower | Higher |
| Main Focus | Torque and controlled power | Higher RPM response |
| Recommended Use | 5–6″ performance | 5″ 4S builds |
| Best Starting Point | 6S freestyle | 4S upgrade |
Choose 1900KV if:
- You fly 6S
- You want a 5-inch freestyle setup
- You are building a 6-inch quad
- You want strong torque
- You use relatively heavy propellers
Choose 2500KV if:
- You fly 4S
- You want a higher-RPM setup
- You are upgrading an existing 4S quad
- You prefer the response of a higher-KV motor
For most pilots moving to a 6S freestyle build, the 1900KV version is the more natural choice.
