i am making a drone but the parts haven't come yet, so i was wondering how you would calculate the maximum distance a drone can travel, or what parameters and equations would you need to estimate this.
the drone uses
4 motors - A2212/5T, 2700kV
1 lipo battery - 2200mAh, 11.1v, average amp draw 25.1A
Thanks 
won't fly far without props.
the propellers are 1045
get http://www.drivecalc.de/ , enter your setup, let it calculate aperage at a static thrust equal to your weight per prop, divide your mAh par motor by that value. Your flighttime will be ~ 1/2 of that value or less.
And the distance depends on that endurance and flight speed and is affected by wind speed and the range
of the RC transmitter/receiver pair and the line of sight visibility.
All calculation is rough and ready without measuring actual power consumption and actual battery capacity.
The answer is probably half the distance that you would like it to be able to fly.
