Safety instructions - DRAFT
Read and follow this guidance before building and flying. Drones can cause injury or property damage if misused.
1. Legal and regulatory
- Know and comply with local laws:
- Registration, identification, and remote ID (where applicable).
- Maximum altitude, no‑fly zones, and VLOS (visual line of sight) rules.
- Insurance and permissions for commercial use.
- Do not fly near people, traffic, airports, or sensitive areas.
- Respect privacy.
2. Workshop and build safety
- Eye protection when soldering, cutting, or pressing inserts.
- Ventilation when soldering and using adhesives.
- Keep flammable materials away from the bench.
- Unplug battery before working on electronics.
3. Electrical and battery safety
- Use quality batteries appropriate for your setup.
- Inspect cells for damage; do not use bloated or punctured packs.
- Charging:
- Use a balance charger on a non‑flammable surface.
- Never leave charging batteries unattended.
- During flight:
- Monitor battery voltage; land before deep discharge.
- Allow batteries to cool before recharging.
4. Propellers and motors
- Always remove props when configuring firmware and testing motors on the bench.
- Keep fingers, clothing, and tools away from spinning props.
- Inspect props for chips/cracks; replace if damaged.
- Install props with correct orientation (CW/CCW) and tighten properly.
5. Pre‑flight checklist
- Mechanical
- All screws tight; snug plus quarter‑turn; avoid over‑tightening
- No cracks or delamination in printed parts.
- Wires secured; no rubbing against props.
- Electronics
- Correct FC orientation; sensors calibrated.
- Receiver bound; channel map correct.
- Motor order/direction verified without props.
- Firmware
- iNav version and target match documentation.
- Failsafe configured according to regulations.
- Battery voltage and alarms set; arming checks enabled.
- Environment
- Open area; wind within safe limits.
- People and pets at a safe distance.
6. Initial flight and testing
- Perform first hover at low altitude; be ready to disarm.
- Increase altitude gradually; check stability and response.
- If oscillations or abnormal behavior occur, land and troubleshoot.
7. Post‑flight and maintenance
- Inspect frame and mounts after hard landings.
- Check motor temperatures; listen for bearing noise.
- Retighten fasteners; recheck electrical connections.
- Log issues and update tuning if needed.
8. Liability and disclaimer
- This is experimental hardware. You are responsible for safe operation and compliance with local laws.
- The authors and contributors are not liable for damages resulting from use or misuse.
- Follow manufacturer guidelines for all third‑party components.
Stay safe, fly responsibly, and enjoy building and tuning COMET.
