Why DroneFlight
Estimate real flight time and range from battery capacity, power draw and reserve — with wind-aware out-and-back range so you always come home with margin.
Wh or mAh
Enter capacity either way (V × Ah handled).
Usable capacity
Plan with 75–80% of nameplate, not fantasy.
Reserve bands
Safe time vs total endurance, clearly split.
Wind-aware range
Out-and-back turn point with head/tailwind.
Payload effect
First-order extra-draw estimate.
Honest failure
Headwind ≥ speed? It says so instead of lying.
How it works
Enter battery
Capacity, usable %, average draw.
Set flight
Speed, wind, reserve.
Read time & range
Safe minutes and the turn-back point.
FAQ
How accurate is it?
As accurate as your average-draw number — the math itself is exact and test-verified.
Does wind matter?
Hugely. The out-and-back solver uses real ground speeds both ways.
What reserve should I keep?
25% is a sane default; 15% minimum.
Who is it for?
FPV pilots, mappers and inspection crews.
Private by design. DroneFlight runs on your iPhone — no account, no tracking.
