How to setup and survey with Max4T XE

🔷 Step-by-Step: Polygon Mission Planning (EVO Max 4T XE)

1. Access Polygon Mission Interface

  • From the main flight screen, tap the “Polygon” icon in the toolbar or Shortcuts.

2. Create the Polygon Area

  • Tap the center point of your target area on the map to generate an initial square.

  • Use the “+” icons to add more corners and reshape the area.

  • Drag the white points to adjust size and shape.

  • Use the cross-arrow icon to reposition the entire polygon.

3. Set Mission Parameters

Once the area is defined, a menu will appear:

  • Gimbal Model and Camera Lens: Choose the payload(s) to use.

  • Mission Name: Name your mission.

  • Altitude: Set flight altitude (20–800m or ft, depending on unit format).

  • Relative Height: Adjust based on takeoff elevation.

  • Flight Speed: Set operational speed.

  • Finish Action: Select what happens after mission ends (Auto RTH or Hover).

  • Signal Loss Action: Choose behavior on disconnection (Continue or Auto RTH).

4. Advanced Settings (Optional)

Configure for data quality or coverage:

  • Front Overlap / Side Overlap (10–90%)

  • Main Course Angle

  • Gimbal Pitch

  • Double Grid (adds 90° second pass)

  • Route Extension

  • Elevation Optimization

  • Coordinated Turns (smooth arcs instead of hard corners)

5. Review and Pre-Flight Check

  • Tap the ✔ check icon to open the Pre-Flight Check.
