Start with the certificate, not the camera
Every buying guide starts with sensor size. In India that is the wrong first question, because an aircraft without a valid Type Certificate cannot obtain a UIN, and without a UIN it cannot legally fly a commercial job.
I have watched three separate operators import an aircraft on the strength of a review video and then discover it could not be registered. That is a six-figure paperweight.
Check the current list of type-certified aircraft before you check anything else. If it is not on the list, the conversation is over regardless of how good the camera is.
Then work backwards from the deliverable
The second question is what you are actually contracted to hand over.
- Survey and mapping: mechanical shutter, RTK module, and a manufacturer-published camera calibration. Rolling shutter introduces distortion that no amount of ground control fully removes.
- Thermal and inspection: radiometric sensor, not a colourised thermal video output. If it cannot export R-JPEG with per-pixel temperature, it is a visualisation tool and not a measurement tool.
- Cinematography: a payload your grading pipeline can actually use. 10-bit log minimum, and check the codec against what your finishing house accepts before you buy.
- Confined space: caged airframe with non-GPS stabilisation. Nothing else will hold position inside a silo.
Service availability decides the real cost
An aircraft that is down for six weeks awaiting a part from overseas costs far more than the price difference that made it attractive. Before buying, get three specific answers in writing from the seller.
- Where is the nearest authorised service centre?
- What is the typical turnaround for a motor or gimbal replacement?
- Are spares stocked in India, or imported per order?
If the honest answer to the third is 'imported per order', treat the aircraft as single-fault-tolerant at best and buy two, or buy something else.
Fleet composition beats fleet size
A common mistake is buying three copies of the same versatile aircraft. It feels like redundancy and it is, but it also means you cannot take a thermal job and a cine job in the same week.
Two aircraft that cover different capabilities plus one spare of your busiest type will win you more work than four of a single model.
Our own fleet is deliberately uneven: two cine-lift aircraft because that is our busiest line, one survey aircraft with RTK, one thermal-equipped aircraft, one caged indoor unit, and one small aircraft that goes everywhere because it fits in hand baggage.
Batteries are the real consumable
Nobody budgets adequately for batteries. Plan on six packs per aircraft minimum for a full production day, and plan on replacing them at roughly 200 cycles or when they will not hold balance – whichever comes first.
In Indian conditions, heat is what kills them. A pack cycled hard at 42 °C in Rajasthan will not see 200 cycles. Budget for annual replacement of your working set, and never store packs in a vehicle.
What I would buy today
For someone starting a commercial operation in India in 2026: one type-certified small-class aircraft with a mechanical shutter and an RTK option, six batteries, a proper case, third-party liability insurance, and the RPC to fly it.
That gets you legally earning on survey, real estate and general cinematography work. Add the thermal payload when a client has actually asked for thermal – not before. Buying capability ahead of demand is how drone businesses run out of cash in year one.
