TJ AEROSENSE FAQ

Questions We Get All the Time

If you’re comparing spray drones, building a complete setup, looking at a robotic mower, or trying to figure out what support you actually need, these are the questions we hear most often.

Spray Drones & Packages

Which new spray drones does TJ Aerosense currently sell?
Our current new-drone lineup centers on the DJI Agras T25P, Talos T60X, and DJI Agras T100. The T25P is the compact Agras option, the T60X gives you a lower-cost 50-liter platform, and the T100 is the 100-liter high-capacity option. We no longer sell new T50 aircraft, but we continue supporting existing Agras customers with parts and service.
Which spray drone is right for my operation?
It depends on more than acreage. Carrier volume, field size and shape, terrain, transport, crew size, refill workflow, charging, and how much capacity you really need all matter. Tell us what you plan to spray, your normal GPA, acres, terrain, and how you want to operate, and we’ll help compare the complete system.
Should I buy an airframe or a complete package?
If you already own compatible batteries, charging equipment, controller hardware, and support gear, an airframe-only purchase can make sense. If you’re starting from scratch, a complete package is usually the cleaner way to make sure the aircraft, batteries, charging, cooling, and power system are planned together. See our spray drone packages.
How many acres can a spray drone cover in a day?
There isn’t one honest number that fits every job. GPA, field shape, ferry distance, turns, wind, obstacles, refill speed, battery workflow, and crew efficiency can change production dramatically. One documented TJ Aerosense T100 sample covered 4,424.73 acres in 47.83 flight hours, or about 92.5 acres per flight hour, but that is a real operating sample—not a guaranteed rate. See the field evidence.
Why do you consider the T100 more versatile?
The 100-liter tank gives it a wider practical working range. At lower carrier volumes you get more acres between refills. At higher GPA, the extra capacity keeps acres per load more practical instead of turning the job into a constant refill cycle. For us, that makes the tank size valuable for flexibility—not only top-end output.
Can you help plan batteries, charging, water, generators, and trailer workflow?
Yes. Those pieces can have just as much impact on production as the aircraft itself. We can help you think through the complete setup based on your acres, GPA, crew, power source, trailer, and refill plan.

Parts, Repairs & Support

Does TJ Aerosense service DJI Agras drones?
Yes. TJ Aerosense is a DJI Agriculture dealer and service center in Huron, South Dakota. We handle Agras parts, repairs, troubleshooting, and warranty assistance. Customers from outside South Dakota regularly bring equipment to our Huron shop as well.
Do you stock Agras parts?
We stock a growing inventory of common DJI Agras parts and accessories. Inventory changes throughout the season, so if you need something specific, contact us or use the Parts section of the website.

Regulations

What licenses and approvals do I need to spray with an agricultural drone?
For most full-size agricultural spray-drone operations, there are both aviation and pesticide requirements. Depending on the aircraft and operation, that can include an FAA Remote Pilot Certificate, aircraft registration, a Section 44807 exemption, a Part 137 Agricultural Aircraft Operator Certificate, applicable airspace/COA requirements, and state pesticide certification or licensing. The exact path depends on the aircraft, weight, substance, state, and type of work. See our Regulations guide.

Segway Navimow

Do Navimow robotic mowers need a boundary wire?
No. Current Navimow models use virtual boundaries and app-based mapping rather than a buried perimeter wire.
Which Navimow model fits my yard?
Acreage is the starting point, but slopes, trees, rough terrain, narrow areas, separate zones, and how complicated the property is can change the recommendation. Send us your acreage and a few details about the yard and we’ll tell you what we would put on it. See the Navimow lineup.
Do you sell commercial robotic mowers?
Yes. We sell the Navimow Terranox commercial lineup for larger turf areas, multi-acre properties, and fleet-style applications.
Do you support Navimow after the sale?
Yes. We can help with model selection, setup questions, accessories, replacement blades, and product support after you buy.

Enterprise Drones & General Questions

Do you sell DJI Enterprise drones?
Yes. We carry DJI Enterprise equipment for uses such as mapping, thermal work, inspection, scouting, and multispectral imaging. Our DJI Agriculture service center and Enterprise repair support are different, so contact us if you have a specific Enterprise support question.
Where does TJ Aerosense work with customers?
Our shop is in Huron, South Dakota, and we work with customers across South Dakota, North Dakota, Minnesota, Iowa, Nebraska, and Montana. Parts can be shipped, and customers often travel to Huron for Agriculture service work.
Why buy from TJ Aerosense instead of just ordering equipment online?
Because we use this equipment ourselves. TJ Aerosense has covered more than 60,000 acres with agricultural drones, logged more than 1,400 flight hours, and accumulated 313 operating days. Our recommendations come from operating, repairing, and supporting the equipment—not just reading a brochure.

Still Have a Question?

Service Details We Want Clear Up Front

TJ Aerosense supports customers across the Northern Midwest, but the repair shop itself is in Huron. These are the details worth knowing before you load an aircraft, ship anything, or buy a complete setup.

Where is hands-on Agras service performed?

All hands-on Agras repair work is completed at the TJ Aerosense service center at 20166 401st Ave, Huron, SD 57350. We sell and support customers in Montana, North Dakota, South Dakota, Minnesota, Iowa and Nebraska, but we do not claim mobile repair locations across those states.

Do you travel to other states to repair drones?

No. Most out-of-state customers bring the aircraft to Huron. Call or text before traveling so we can review the issue, check likely parts and tell you what information or equipment to bring.

Can I ship an aircraft to TJ Aerosense for repair?

Contact us before shipping anything. We have handled a shipped aircraft before, but shipping is not our normal repair process. Aircraft condition, batteries, chemical residue, packaging and the specific problem all affect what is practical. We will review the situation first and help decide whether bringing the aircraft to Huron or another route makes more sense.

Do you provide setup and training?

Yes. We help customers understand aircraft setup, charging, cooling, mapping, application workflow, cleaning, maintenance and safe day-to-day operation. The exact training scope depends on the aircraft, package and customer experience, so it should be confirmed with the quote rather than assumed from a generic package name.

What support is available after the sale?

We help with operational questions, troubleshooting, common parts, repairs, maintenance and warranty-claim assistance when applicable. Part availability, repair timing and warranty decisions are confirmed case by case; we do not promise a turnaround time before the aircraft and issue are reviewed.

What should I send if the drone goes down in season?

Start the repair request in the DJI SmartFarm app so the aircraft information and required photos come through correctly. For urgent downtime, submit that request first and then call or text (605) 350-7130.

Useful information includes:

  • Aircraft model
  • Error code or warning
  • Whether the aircraft is grounded
  • What happened immediately before the problem
  • What you already tried
  • Clear photos or a short video when helpful

Do not open high-voltage equipment or bypass safety devices while trying to diagnose a problem.

Still not sure which path fits?

Tell us what aircraft you have and what you are trying to accomplish. If we do not know the answer yet, we would rather verify it than make one up.
