Achieving uniform spray coverage is critical for effective plant protection, and uniform speed operation is the cornerstone. Inconsistent flight speed leads to over-application or missed areas, wasting chemicals and harming crops. Modern plant protection drones, such as those featured at www.uflystar.com, offer advanced speed control systems to address this challenge. Here is a practical method for setting uniform speed operation.

First, access the drone’s flight controller app or remote controller interface. Navigate to the "Mission Settings" or "Operation Parameters" menu. Look for the "Uniform Speed Mode" or "Constant Velocity" option—this is usually found under "Spraying Settings." Enable this mode to override manual throttle fluctuations.

Next, set the target speed value. For most crops, a speed between 3 to 6 meters per second is recommended. Lower speeds (3–4 m/s) suit dense foliage or high-volume spraying, while higher speeds (5–6 m/s) are ideal for open fields. Enter the desired value in kilometers per hour (e.g., 14–21 km/h). The drone’s GPS and inertial sensors will then automatically adjust motor output to maintain this speed, even in mild wind.

Then, calibrate the acceleration and deceleration ramps. In the same menu, set the "Acceleration Ramp" to a gentle value (e.g., 1.5 m/s²) to prevent sudden jerks that cause spray streaks. Similarly, define a "Turn Smoothing" parameter—this ensures the drone reduces speed slightly before turning and accelerates evenly after, maintaining consistent droplet deposition on row ends.

Crucially, perform a pre-flight test. Use a dry run over a measured 50-meter line, observing the on-screen speed readout. Adjust the "Speed Correction Factor" (typically ±10%) if the actual GPS speed deviates from the set value. For terrain-following drones, also enable "Terrain Adaptive Speed" so that climbs and descents do not alter ground speed.

Finally, synchronize speed with pump flow rate. On your uflystar drone, link the spray rate to speed using the "Auto Flow Compensation" feature. This ensures that the volume per hectare remains constant, regardless of minor speed fluctuations. After setting, save the profile as a named preset for repeated use.

By following these steps, operators can achieve uniform coverage, reduce chemical waste, and improve crop safety. For detailed model-specific guidance, always refer to your drone’s manual or visit www.uflystar.com for technical support and firmware updates. Uniform speed is not just about flying straight—it’s about precision agriculture that saves time and money.
