Are you looking for an aerial spraying system but don’t want to spend a fortune? Or perhaps you are conducting a research project and don’t have a massive budget (yet), or maybe you have a large home garden and want to bring some technology home? Well you’ve found the best crop dusting drone on the market! Now listen, we don’t like to use the word “cheap” but seriously – this is one cheap spraying drone!

Its compact size, folding arms and propellers make this a great tool for any field. This super-affordable sprayer drone can be used in typical agriculture applications, but also for deicing, vector control, or even cleaning solar panels or rooftops! Many customers are choosing this sprayer drone to prove their drone-spraying concepts with minimal investment – a great entry into the spraying UAV sector! Our M4E is the industry-leader of capability, reliability and features for this price… you just won’t find a more capable, built-for-spraying drone than the M4E at this cheap price!

What does the M4E offer? First off, a full GPS Ground Station for automatic flight planning! Plus the super-easy A-B spray planning feature. And, get this – full spraying automation! This is a big deal! That means that the drone automatically turns on and off the spray pump when it is over the field; you can also program the drone to return home when it is out of spray and then automatically resume right where it left off. 

The modular design ensures quick and affordable in-field maintenance or repairs. Plus, its extreme water-resistance make it great for quick decontamination and rinsing. See the long list of included Safety & Tech in the “Features” tab.
