Can it still operate if the drone loses external power?
Yes. The built-in UPS allows the controller to continue running for
up to 30 minutes, ensuring controlled emergency actions and
preventing total system failure.
How does the software anti-sway technology help?
The advanced anti-sway algorithm enables stable hovering and
mission completion even under magnetic interference, dual-antenna
failure, or harsh wind conditions.
Does it support multi-remote-controller usage?
Absolutely. It allows multiple RC inputs and lets you configure
priority logic directly at the flight control layer, making it
suitable for cooperative operations and training scenarios.
What safety features does it have for motor or power failure?
It supports:
- Emergency landing for 4-axis drones with a single power failure
- Safe return for 6-axis single-power failure
- Controlled multiple landing modes for 6-axis and above
How does the controller handle magnetic interference?
It uses an automatic heading calibration algorithm designed to
resist magnetic field disruptions, ensuring accurate orientation
and navigation.
Does it provide flight data storage?
Yes. It includes an onboard 32GB SD card for long-duration flight
log recording, essential for diagnostics, compliance, and mission
reviews.
Is the flight controller weather-resistant?
Yes. It meets IP65 waterproof and dustproof standards and is housed
