• Analog FPV: ZENCHANSI 600mW + CADDX analog camera

The integrated OSD module allows real-time overlay of flight telemetry without external OSD. Radiolink has ensured plug-and-play compatibility via both socket and solder pad design.

GPS Precision and Return to Home Safety

With the Radiolink TS100 GPS module, the Wolf QAV250 achieves 50cm positioning accuracy and supports:

• Auto Return-to-Home (RTH) on signal loss or low voltage

• Waypoint Navigation with custom parameters for flight speed and altitude

• Geofencing compliance for safe and legal operation

Trainer-Friendly Manual Mode

Ideal for training, the drone allows beginners to progressively switch between:

1. PosHold Mode

2. Altitude Hold Mode

3. Stabilize Mode

4. Manual Mode

This allows users to adapt gradually, with hover recovery built-in at each step.

High-Speed Aerial Videography

With Kalman Filter Algorithms, the QAV250 enables fast and stable tracking in Altitude Hold Mode, capturing fast-action scenarios like F1 racing or extreme environments. Its maximum speed of 180km/h allows smooth dynamic shots without drift.

Robust Power and Charging System

• Flight Time: ~15 minutes (HD VTX)

• Balance Charger: HOTA T6 15A, 300W, 94% efficiency

• ESC: FLYCOLOR 55A 4-in-1

• Battery: 6S 1300mAh 95C Gensace

This system ensures minimal power loss and consistent performance in high-G maneuvers and aggressive throttle bursts.

Walksnail Avatar HD Goggles X (Optional)

• H.265 Encoding with 1080P/100FPS FPV

• 50 FOV, low latency
