KST CM07 V6.0 HV Micro Servo – 2.4kgf.cm, 0.06 sec/60°

The KST CM07 V6.0 HV Digital Micro Servo is an ultra-lightweight, ultra-thin servo designed for high-performance F3K/DLG gliders, indoor models and lightweight RC aircraft.

Weighing just 7 grams and measuring only 7.5 mm in thickness, the CM07 delivers an impressive combination of low weight, compact dimensions, speed and precision.

At 8.4V, the CM07 provides 2.4kgf.cm of torque and an extremely fast 0.06 sec/60° response time, making it an excellent choice for applications where every gram matters and fast, precise control is essential.

Its coreless motor, steel gears and dual ball bearings provide smooth and reliable operation, while the programmable digital electronics allow the servo to be configured to suit different applications.

Ultra-Thin Design – Only 7.5mm

The biggest advantage of the KST CM07 V6.0 is its extremely compact design.

With a thickness of only 7.5 mm and a weight of just 7 grams, the servo can fit into very thin wings and fuselage sections where a conventional micro servo simply won't fit.

This makes the CM07 particularly suitable for:

• F3K / DLG gliders

• F3B and lightweight gliders

• Indoor RC aircraft

• Lightweight electric models

• Competition models

• Small ailerons and control surfaces

• Lightweight RC aircraft where weight is critical

The compact size allows designers and pilots to minimize servo installation space while keeping the aircraft as light as possible.

Extremely Fast 0.06 sec Response

Despite its tiny size, the CM07 delivers impressive speed.

At 8.4V, the servo reaches 0.06 sec/60°, providing fast and precise control response.

Performance across the voltage range:

• 0.14 sec/60° @ 3.5V

• 0.11 sec/60° @ 4.2V

• 0.08 sec/60° @ 6.0V

• 0.07 sec/60° @ 7.4V

• 0.06 sec/60° @ 8.4V

This makes the CM07 particularly attractive for F3K/DLG competition models, where rapid control response can be important.

2.4kgf.cm of Torque

The CM07 may be small, but it offers a surprisingly high torque output for a 7g servo.

At 8.4V, it produces 2.4kgf.cm of torque.

Torque output:

• 1.10kgf.cm @ 3.5V

• 1.40kgf.cm @ 4.2V

• 1.80kgf.cm @ 6.0V

• 2.10kgf.cm @ 7.4V

• 2.40kgf.cm @ 8.4V

This provides plenty of power for the small control surfaces typically found on lightweight gliders and indoor aircraft.

Coreless Motor for Fast and Precise Control

The CM07 uses a coreless DC motor designed for fast response and smooth operation.

The coreless design contributes to the servo's quick response while keeping the overall weight extremely low.

Combined with KST's digital electronics, the motor provides precise positioning and excellent control response for demanding lightweight aircraft applications.

Steel Gears and Dual Ball Bearings

The CM07 features a durable steel gear train despite its extremely small size.

The output shaft is supported by two ball bearings, helping to maintain smooth movement and excellent centering accuracy.

This combination gives the CM07 a strong balance between low weight, durability and precision.

High-Strength Polycarbonate Case

To keep weight and dimensions to a minimum, the CM07 uses a high-strength polycarbonate case.

At only 7 grams, it is designed specifically for aircraft where reducing servo weight can have a noticeable effect on the final model weight.

Its ultra-thin 7.5 mm profile makes it particularly easy to install inside narrow wings and lightweight fuselages.

HV Compatible and Fully Programmable

The CM07 V6.0 supports a wide 3.5–8.4V operating range, making it compatible with both conventional and modern HV receiver systems.

The digital electronics are fully programmable, including programmable soft start.

The servo can be programmed using compatible KST Tool #3 and KST Tool #5.

Ideal for F3K, DLG & Indoor RC Models

The KST CM07 V6.0 is an excellent choice for:

• F3K / DLG competition gliders

• Lightweight RC gliders

• Indoor RC aircraft

• Lightweight aerobatic models

• Small electric aircraft

• Lightweight control surfaces

• Applications where servo thickness and weight are critical

For pilots looking for an ultra-light, ultra-thin and extremely fast micro servo, the CM07 V6.0 offers an outstanding combination of performance and size.
