Look, if you've been dealing with those smaller 20L sprayers that run out halfway through a field, you already know the pain of constant refilling and lost time—we've had buyers switch to this one specifically for the 35L tank that actually handles a full acre or more on a single charge, and the IP67 rating means you're not panicking if a sprinkler kicks on mid-flight or you have to land in damp grass.
It's a 400mm frame with a plastic/metal composite shell that feels solid in hand, not flimsy like some of the cheaper units we've seen, and the dual RTK plus GPS navigation keeps you locked in at ≤0.5m terrain tracing accuracy even on slopes or uneven ground, which basically eliminates drift issues when you're working near ditches or power lines.
The droplet size range runs form 50 to 500μm and you can adjust it on the fly depending on whether you're hitting broadleaf weeds or a dense canopy—most growers we talk to end up settling around 200-300μm for general crop protection, but the centrifugal nozzle handles the finer stuff fine too, just don't expect it to work well for ultra-low volume applicaion under 20L/ha because the pump isn't designed for that.
Charging time is about 10 minutes for a full battery, which is pretty fast compared to the 45-minute units some competitors push, and teh 30-minute flight duration gives you enough window to cover a decent plot before swapping packs, though we usually stock extra batteries (2000mAh each) so you can hot-swap in the field without downtime.
We do offer OEM options on the RY-ku401 if you're branding it yourself—just give us your logo specs and we'll handle the silk-screening on the shell, lead time is usually 20 days or so for batches of 50 units or more, and every shipment comes with ISO9001, FCC, and RoHS documentation plus a standard 18-month warranty that covers the motors and flight controller.
