I'm looking at getting an Agras T30 for our 150-acre corn operation. The specs show 18 minutes hover time with no payload, but I need real-world data on flight times with various spray loads.

Specifically interested in: actual flight time with 20L vs full 30L tank, how wind affects these numbers, and whether the GPS terrain following impacts battery drain significantly.

Also wondering about battery degradation - are you seeing the promised 1,000 charge cycles, or do they start dropping capacity earlier?

With my T30, I get about 10-12 minutes flight time with a full 30L load in calm conditions. At 20L, it's closer to 14-16 minutes. Wind over 15mph cuts that by 20-30% easily.

GPS terrain following does eat battery, but not as much as you'd think - maybe 1-2 minutes difference on hilly terrain.

Battery degradation hits around cycle 800 in my experience, not the full 1,000. I track capacity with a cell checker and see noticeable drops after heavy spray seasons.

Pro tip: rotate your battery sets and don't charge to 100% unless you're flying immediately.

Just got my T30 last month and seeing similar numbers to what others posted. The flight time calculator in DJI Agras app is pretty accurate for planning missions.

One thing - cold weather kills battery performance. Lost 40% flight time spraying fungicide in 35?F temps last week.
