Installation Guide
Parachute Compartment Setup
- Mount the parachute compartment securely onto the drone.
- Attach parachute cords to the designated drone hooks.
- Fold the parachute properly to prevent entanglement.
- Arrange the cords neatly and position the pilot chute on top.
- Secure the compartment lid, ensuring a firm closure.
Parachute Installation Guide
- Adjust cord lengths to position the parachute center slightly forward of the drone’s center of gravity.
- Secure the parachute cords using fasteners.
- Check tension to prevent loose or overly tight cords.
- Organize the suspension lines for a clean deployment.
- Fix the tail cords, ensuring the parachute is properly aligned.
- Place the folded parachute inside the compartment, threading cords through the lid opening.
- Connect the parachute cords to the drone hooks securely.
- Lock the compartment lid, ensuring stability with a mechanical lock.
Remote & Flight Control Settings
-
Pixhawk-Compatible – Supports Pixhawk flight controllers and Mission Planner configuration:
- Go to Configuration > Full Parameters > Set CHUTE_ALT_MIN (minimum parachute altitude).
- Assign CHUTE_CHAN to channel 7 and set CHUTE_SERVO_OFF/ON PWM values.
- Set AUX2 as the parachute activation switch for remote trigger.
- Automated parachute deployment: In waypoint mode, set the last waypoint to DO_PARACHUTE for automatic deployment.
Comparison & Advantages
| Issue with Other Parachutes | FY-WJ401 Parachute Upgrades |
|---|---|
| Weak knotting, high risk of detachment | Secure fasteners ensure stable deployment |
| No pilot chute, leading to high failure rates | Integrated pilot chute prevents entanglement |
| Unreliable cord attachment, prone to breaking | Reinforced cords withstand 20KG+ impact |
| No vent hole design, causing unstable deployment | Engineered vents ensure controlled descent |
| No reinforced edges, leading to tearing | Strengthened edges with 30KG+ tensile capacity |
Applications
- Industrial Drones – Enhances safety for logistics, inspection, and monitoring drones.

Product parameters for Chu Zhou's 4kg-15kg UAV parachute include weight, diameter, load capacity, rope length, safe opening height, touchdown speed, and folding volume. Colors are randomly delivered. Specifications vary by model, with the 8kg version weighing 250g and having a 2.9M nominal diameter.
Installation process: Attach the umbrella bin to the fuselage. Tie the rope to the buckle. Neatly stack and place the umbrella in the bin. Tidy the rope, placing the guide umbrella on top. Cover the protruding part with a card. Finally, cover the compartment with the steering gear.
Parachute Installation Tutorial: Adjust each rope length for balance, ensuring the center is slightly forward of the aircraft's center of gravity. Secure with cushion screws and harness caps. Install folded parachute in compartment, pass rope through canopy hole, and clamp hatch cover.
Ground station hand-self integrated umbrella opening settings are detailed. Test conditions include mission planner version 1.3.48, PIXHAWK2.4.6 hardware, and firmware 3.7.1. Steps involve configuring parameters for parachute deployment, setting AUX2 as the fast-closing channel, and selecting flight plans to automate parachute opening after waypoints.
