Our large capacity spraying drone boasts 20L capacity mixed with industry-leading flight times!

SKU: woo-single Category:


The M8A Pro (formerly known as the AG V8A+) is our large capacity spraying drone, perfect for larger fields and higher application rates.  Standard features include terrain sensing, a flow-rate meter and full spray pump automation! Be sure to check out the “Research” tab to see how the M8A Pro large capacity spraying drone stacks against the DJI Agras, T-16 or the T20 drone!

How It Works


How Crop Sprayer Drones Work

You can operate this drone in three different ways; this give you ultimate flexibility and makes it easy to accomplish any spraying job. All modes offer automatic Terrain Following (if equipped), and either manual or fully automatic sprayer functionality.


Fast | Flexible | Simple

Easy Crop Duster Drone

This is the fastest method for spraying and works best for square / rectangle shaped areas. As with Fully Automatic, when battery or liquid is low, the drone returns automatically and will resume exactly where it left off once replenished.

  1. Fly the drone to the corner of the field where you’d like to start your mission
  2. Toggle the A-B switch to the “A” position; the app will confirm that point A has been recorded
  3. Fly the drone to the opposite end of the field (the path between these two points will be the line that the drone repeats)
  4. Toggle the A-B switch to the “B” position; the app will confirm that point B has been recorded
  5. Push the RC stick to the left or the right; the drone will slide over to the direction you instructed and it will fly back towards the “A” side of the field and will repeat until you stop it.

The distance between rows (swath), speed and height are based on the parameter you set in the app. If needed, you can shorten or extend either end of the field during the mission


As you might suspect, this is the most basic form of operating the spraying drone. In this mode, you fly the drone with the Remote Controller (RC) and can use either an automatic (speed dependent) pump or manual pump mode. The terrain sensor allows you to fly on hillsides with ease. We recommend you use the GPS position hold feature so that the drone holds a hover and doesn’t drift in the wind.


Accurate | Precise | Effortless

This awesome feature allows you to focus on flying instead of fumbling with pump speed and extra calculations. Just select the desired flow rate / pump speed and the system does the work for you! The pump speed will adjust to account for flight speed and will turn off as appropriate to avoid over-spraying. When the system detects you are out of chemical, the pump will shut off and the drone will return to its home position automatically! And yes, it leaves a mark where it left off so it can automatically resume 🙂

An enhanced safety feature turns off the pump if there is an emergency 😉
