THOPTER
Drones, up close — reviews and buying guides, FPV and aerial imaging, flight and the tools every pilot needs.
From choosing your next drone and planning a shoot to reading the rules, checking your kit, and sharpening your flying, Thopter pairs free hands-on pilot calculators with practical guides and a richly illustrated museum. Fly smarter, film better.
Drone Tools & Calculators
Free tools for every flight — flight-time and range estimates, coverage and photo-mapping planning, field-of-view and payload checks, and the numbers every pilot needs before takeoff.
Drone Flight Time Calculator
Estimate how long your drone can stay airborne from its battery capacity, average current draw, and the percentage of the pack you safely use — a quick endurance figure for planning missions
LiPo Voltage Calculator
Turn a pack's cell count into its nominal, fully charged, and storage voltages — check what your charger should read and store batteries at the level that keeps them healthy
Drone Range Calculator
Estimate how far your drone can travel from its cruise speed and flight time — a straight-line range figure, with a reminder to halve it for out-and-back missions
Ground Sampling Distance Calculator
Work out the ground sampling distance of a survey from your sensor width, altitude, focal length, and image width — the real-world size of a pixel and the headline resolution of a map
Battery Charge Time Calculator
Estimate how long a pack takes to charge from its capacity and your charger's output current, including a 10% overhead for the constant-voltage tail — plan your turnaround between flights
Drone Coverage Calculator
Estimate the area a single battery can map or spray from your flight time, ground speed, and swath width — a best-case hectares-per-battery figure for mapping and agricultural missions
The Drone Museum
Explore an immersive museum of the machines and ideas that shape the way we fly — early kites and the pioneers of flight alongside the rise of the quadcopter, the worlds of FPV and racing, aerial photography and cinematography, and the sensors and airframes that make it all work, each in its own gallery, so you can get to know the stories behind every drone: how each one came to be, what makes it matter, and the role it plays in shaping how we see the world from above.
