🔍 Detailed Technical Specification Breakdown

---

🛠️ Product Type

Replacement Arm for Drone Frame
This is a single drone arm meant to replace a broken or damaged one in the Martian-III or Reptile 260mm quadcopter frames. Instead of replacing the full frame, you can just swap out the arm, saving time and cost.

---

📦 Compatible Frame Models

Martian-III / Reptile 260mm Quadcopter Frames
This arm is specifically designed for these two widely used frames in the FPV racing and freestyle community. It fits perfectly with their layout and hole placement, requiring no modifications.

---

🧱 Material

3K Carbon Fiber
This is a woven composite material known for its:

• High tensile strength (resists snapping during crashes)

• Lightweight nature (minimizes drone load)

• Rigidity (helps maintain flight stability)
  3K refers to the carbon fiber weave type—3,000 strands per tow—offering a perfect blend of strength and flexibility.

---

📏 Length (Arm)

Approx. 120mm (motor center to frame center)
This is the distance from the middle of the frame to where the motor mounts, which determines your propeller size support (in this case, 5-inch props). A 260mm frame refers to the diagonal motor-to-motor distance, and this arm fits precisely in that geometry.

---

📐 Thickness

 

4mm
Thicker arms are more durable and better at absorbing impact forces. At 4mm, this arm is ideal for aggressive flying, freestyle flips, and crash recovery.

---

🔩 Motor Mount Hole Pattern

16x16mm and 19x19mm
These hole patterns support the majority of brushless motors in the FPV drone world—especially:

• 2204

• 2205

• 2207

• 2306

It allows you to mount motors using standard M3 screws, making it compatible with most 5″ setups.

---

⚖️ Weight

Approximately 12–15 grams per arm
This low weight contributes to:

• Longer flight times

• Improved agility

• Less strain on motors & ESCs
  Even with this lightweight design, the carbon fiber construction ensures it’s not flimsy or weak.

---

🧭 Frame Style Support

X-Frame layout (4-arm configuration)
This means your drone is built with four symmetrical arms in an X shape. This layout offers balanced flight characteristics and is widely used in racing and freestyle drones.

---

🔌 Compatible Motor Sizes

2204, 2205, 2207, 2306, etc.
These are standard FPV drone motors used with 5-inch propellers. This arm allows proper fitting for these motor types without stressing the carbon fiber or screws.

---

✈️ Compatible Prop Size

5-inch propellers
The arm’s length and frame spacing make it suitable for 5-inch props, which are standard in racing and freestyle FPV drones due to their balance of power and control.

---

🔧 Installation Method

Bolt-on (no drilling required)
Installation is simple:

1. Remove the broken arm by unscrewing it.

2. Place the new arm in the same position.

3. Tighten it using the same screws or replacements.

No drilling, cutting, or modifying required—this arm is plug-and-play.

---

🎨 Color/Finish

Matte black carbon fiber with visible 3K weave
Gives your drone a professional and aggressive look, while the weave also visually indicates the carbon fiber quality.

---

📦 Package Includes

1 × Replacement Arm
Note: Screws may or may not be included depending on the seller or variant. Always check before ordering.

    🏗️ Premium Carbon Fiber Construction – Explained in Detail

    This part emphasizes the material quality and practical benefits of the replacement arm. Let’s break it down:

    ---

    🔩 “Constructed from durable 3K carbon fiber”

    • 3K carbon fiber refers to a high-grade composite material made of carbon fibers woven in a 3,000-filament (3K) pattern.

    • It is widely used in aerospace, automotive, and drone applications because of its exceptional strength-to-weight ratio.

    • This material provides:

      • High tensile strength (resists breaking under force)

      • Rigidity (maintains shape even under stress)

      • Impact resistance (perfect for drone crashes)

    ---

    ⚖️ “Offers a perfect balance of strength and weight”

    • The arm is strong enough to hold heavy motors and survive high-speed crashes.

    • Yet it’s lightweight, so it doesn’t weigh the drone down, which is crucial for:

      • Martian-III 260mm Replacement Arm Flight time

      • Martian-III 260mm Replacement Arm Agility

      • Martian-III 260mm Replacement Arm Battery efficiency

    This balance is essential in FPV drones, where performance depends on both durability and speed.

    ---

    💥 “It can endure hard crashes and aggressive flight styles”

    • FPV drone flying—especially freestyle and racing—often involves:

      • Sudden flips and spins

      • High-speed impacts

      • Crashes into trees, concrete, or ground

    • This carbon fiber arm can absorb shock and resist snapping, meaning fewer replacements and more time in the air.

    ---

    🚀 “Maintaining the lightweight agility needed for freestyle or race”

    • Lightweight components are essential in freestyle and racing drones to:

      • Improve maneuverability

      • Allow faster cornering and acceleration

      • Reduce strain on motors and batteries

    • This arm helps your drone remain nimble and responsive, giving you better control during flight.

      🚁 Lightweight Yet Rigid

      This feature focuses on how the physical properties of the replacement arm benefit your drone’s performance, stability, and efficiency during flight.

      ---

      ⚖️ “Its lightweight design reduces strain on your motors and ESCs”

      • The arm is made of lightweight carbon fiber, which helps keep the drone’s overall weight low.

      • Why this matters:

        • Heavier frames require more power from the motors and increase the load on the ESCs (Electronic Speed Controllers).

        • Over time, that can lead to overheating, shorter battery life, or even component damage.

      • A lightweight arm means:

        • Less energy consumption

        • Longer component lifespan

        • More efficient battery usage

      ---

      🎮 “Improving flight control, responsiveness, and flight time”

      • Lighter arms contribute to a drone that is:

        • Faster to respond to stick input

        • Easier to maneuver in tight spaces

        • More efficient in flight, increasing hover time and range

      • For freestyle pilots and racers, this means:

        • Sharper flips, rolls, and yaw spins

        • Precise control in acrobatic movements

        • Competitive edge during races

      ---

      🧱 “The rigid build minimizes vibrations”

      • Rigidity means the arm doesn’t flex or bend easily, even during sudden movements or crashes.

      • This reduces micro-vibrations that can:

        • Interfere with flight controller sensors

        • Distort FPV camera footage

        • Cause unwanted shaking in the air

      • A rigid arm helps your drone fly smoother and more predictably.

      ---

      🎥 “Leading to smoother FPV footage and better stability during maneuvers”

      • Vibrations often cause “jello” effect or shaking in FPV video.

      • With rigid arms, your camera stays stable, and gyro data remains accurate, resulting in:

        • Clearer video

        • More stable flight

        • Less interference with the drone’s stabilization system.
