SPIDER Automation Cpro-X’3 HX155mm Carbon-Fibre Racing Drone Frame | 3K Carbon Plates & Four 80mm Propeller Protection Ducts
Description
The SPIDER Automation Cpro-X’3 HX155mm Racing Drone Frame Kit is a compact multirotor frame combining carbon-fibre plates and 3D-printed structural components. Designed around a 155mm wheelbase, this HX-type split-frame platform incorporates four propeller protection ducts with an 80mm diameter specification. Its hybrid construction is intended for compact racing and aerial video configurations where frame dimensions, component placement and propeller clearance are important during aircraft integration.
The primary structural assembly uses 3K carbon-fibre plates, with a 3mm bottom plate and 1.5mm upper plate. The internal standoff height is approximately 30mm, providing space within the frame for compatible flight electronics and associated equipment. The main-frame area also provides provision for camera and accessory installation, allowing the aircraft configuration to be planned around the available mounting space.
The kit includes four 3D-printed 80mm propeller protection ducts. These components form part of the frame’s enclosed propeller arrangement and must be matched with suitable motor and propeller dimensions. With a stated frame-kit weight of 127g, the Cpro-X’3 is intended for compact builds where the complete propulsion, battery and electronics configuration must be evaluated against the frame’s physical layout and weight.
Carbon-Fibre & 3D-Printed Frame Construction
The Cpro-X’3 uses a hybrid construction approach, combining 3K carbon-fibre plates with 3D-printed components. The carbon-fibre plates form the primary plate structure, while the printed parts provide the geometry required for the frame’s integrated assembly and propeller protection arrangement.
- 3K Carbon-Fibre Material: The main frame plates use 3K carbon-fibre construction, a material commonly selected for lightweight structural components in multirotor airframes.
- 3mm Bottom Plate: The lower plate provides the specified 3mm structural thickness.
- 1.5mm Upper Plate: The upper plate forms the top section of the split-frame assembly.
- HX-Type Split Structure: The frame uses an HX-type split configuration rather than a conventional single-piece plate layout.
- 3D-Printed Components: Printed parts form part of the frame assembly and include the four supplied propeller protection ducts.
- Compact Structural Layout: The 155mm wheelbase defines the frame’s compact motor-layout class.
Propeller Protection Duct Configuration
The frame kit includes four 3D-printed propeller protection ducts, each specified with an 80mm diameter. These ducts are designed as part of the frame’s propeller-enclosure arrangement. Their internal clearance and mounting geometry must be matched with the selected motor and propeller combination.
- Four-Duct Arrangement: The package includes four individual 3D-printed protection ducts for the four-propeller frame configuration.
- 80mm Duct Diameter: The specified duct diameter provides a reference for checking propeller size and clearance.
- Propeller Compatibility Checks: Confirm the actual propeller diameter, blade profile and operating clearance inside each duct before powering the aircraft.
- Integrated Frame Packaging: The duct components are supplied as part of the Cpro-X’3 frame kit rather than as separately selected accessories.
The 80mm duct dimension should not be treated as confirmation that every nominally 3-inch propeller will fit. Actual blade-tip clearance depends on the duct’s internal geometry and the selected propeller design.
Internal Layout & Camera Integration
The main-frame area provides space for mounting a camera and other compatible accessories. The approximately 30mm internal standoff height is an important reference when planning the placement of the flight controller, power distribution hardware, receiver, video equipment and wiring.
- Internal Electronics Space: The split-frame arrangement provides an internal installation area for compatible flight-control and electronic components.
- Approximately 30mm Standoff Height: Provides a vertical-space reference for component stacking and wiring layout.
- Camera Installation: The main-frame area is designed to accommodate camera installation, subject to the camera’s dimensions and mounting arrangement.
- Accessory Integration: Additional compatible onboard accessories can be planned around the available frame space.
- Wiring Clearance: Component placement should maintain clearance from moving propellers, motor wiring and duct structures.

Installation & Operating Recommendations
- Verify Component Compatibility: Check the dimensions and mounting arrangements of the selected motors, flight controller, ESCs, battery and camera against the frame before assembly.
- Check Propeller-to-Duct Clearance: Measure the actual propeller diameter and blade-tip clearance inside each 80mm duct. Do not assume compatibility based only on the nominal 3-inch propeller class.
- Inspect Carbon-Fibre Plates: Check the upper and bottom plates for cracks, delamination, edge damage or deformation before installation.
- Inspect Printed Components: Examine all four ducts and other printed structural parts for cracks, incomplete sections or damaged mounting areas.
- Secure the Split-Frame Assembly: Align the frame plates and standoffs correctly, then tighten the fasteners evenly using compatible hardware.
- Plan Electronics Placement: Use the approximately 30mm internal standoff height as a packaging reference and verify that installed components do not interfere with one another.
- Provide Cable Clearance: Route motor, ESC, battery and signal wiring away from propeller blades and other moving components.
- Check Camera Mounting: Confirm that the camera is securely mounted and that its position does not obstruct the ducts or interfere with the frame assembly.
- Verify Motor and Propeller Alignment: Check that each motor is securely mounted and that the propellers rotate freely without contacting the protection ducts.
- Evaluate Complete Aircraft Weight: Include the motors, ESCs, flight controller, camera, battery and other accessories when assessing the final aircraft weight and propulsion requirements.
- Perform Pre-Flight Inspection: Check fasteners, frame integrity, wiring, motor operation and propeller clearance before flight.
- Reinspect After Impact: Examine the carbon-fibre plates, printed ducts and mounting points after collisions or hard landings, replacing damaged components before further operation.
