However, increased payload also increases the demands on:
-
Motors
-
Battery
-
Frame
-
Flight controller
-
Landing gear
-
Pump
The manufacturer should clearly state the maximum takeoff weight and recommended operating payload.
Spraying Performance
A professional crop spraying drone manufacturer should provide detailed information about its spraying system.
Pump Flow Rate
The pump controls how much liquid is delivered to the nozzles.
Important parameters include:
-
Flow rate
-
Pressure
-
Power consumption
-
Control method
-

-
Wind
-
Liquid properties
Therefore, advertised maximum width should be evaluated together with recommended operating parameters.
Battery Performance
Battery performance directly affects commercial drone productivity.
A spraying drone operates with a much heavier load than many recreational drones, especially when the tank is full.
When evaluating a battery system, buyers should check:
-
Voltage
-
Capacity
-
Weight
-
Charging time
-
Cycle life
-
Battery management
-
Temperature protection
-
Charger specifications

Flight time can vary according to:
-
Payload
-
Wind
-
Temperature
-
Flight speed
-
Battery condition
-
Flight route
-
Aircraft configuration
Ask the manufacturer:
“Is the quoted flight time measured with an empty tank or with the recommended operating payload?”
This provides a more meaningful comparison.
