Drone Calculators
Free drone calculators: flight time estimator, FPV video range, payload capacity, motor thrust, battery life, and performance tools.
Drone Video Storage Calculator
Calculate SD card storage needed for drone footage based on resolution, bitrate, and total flight time. Compare 1080p, 2.7K, and 4K requirements.
Drone Photogrammetry Coverage Calculator
Calculate ground area covered per drone battery for photogrammetry mapping. Enter altitude, sensor specs, and overlap to get acres or hectares per flight.
FPV Goggle Field of View Calculator
Calculate FPV drone goggle field of view at any flight distance. Compare DJI, Walksnail, and Fatshark goggle FOV and see screen-equivalent distance.
Drone Battery Capacity Calculator
Calculate the battery capacity your drone needs for a target flight time. Enter motor count, current draw, and safety reserve to size your battery correctly.
Drone Propeller Pitch Speed Calculator
Calculate the theoretical pitch speed of a drone propeller from its pitch and motor KV rating. Learn how propeller specs affect maximum airspeed and efficiency.
Drone Return-to-Home Altitude Calculator
Calculate the safe minimum return-to-home (RTH) altitude from highest local obstacle and clearance margin. Avoid trees, towers, and terrain on auto return.
Drone Flight Time in Wind Calculator
Estimate drone flight time reduction caused by headwind. See how wind speed affects battery drain and remaining flight time.
Drone Payload Effect on Flight Time Calculator
Calculate how extra payload reduces drone flight time. Enter base flight time and payload weight to estimate remaining fly time with any load attached.
FPV Video Range Calculator
Estimate FPV video transmission range based on transmitter power and antenna gain. Calculate theoretical line-of-sight distance.
