How many days should a tank of gas last in my car?
You would need to know fuel capacity and average consumption.
I fly a light V1 size jet using a micro jet V3 and a 1300mAh battery.
I fly with the throttle at 60% most of the time and 100% when I do things where I need the power. It last a lot longer than 5 minutes. At full power, it last less than 3 minutes.
***************************************************
This is from a tutorial thread I started called The equations we use .

This is the equation for estimating flight duration:
Amp draw will depend on load and the motor's abilities. A lot of people use this formula to figure max flight time under a given load.

[(mah/1000) /average amp draw] x 60 = minutes of flight time

For a 2200mah battery and a 30 amp motor.

[(2200mah/1000) /30amps] x 60 = 4.4 minutes

If the 2200 mah battery is fully charged and working perfectly, you can draw 30 amps from it for 4.4 minutes. That's if it dumps its entire load at the motor's full amp draw, which I would not recommend.

**************************************************

A jet going straight up at full throttle, using a 30amp motor, draws almost 30 amps.

A jet going straight down at full throttle, using a 30amp motor, draws less than 10 amps.

The bottom line is:
The load that is placed on a motor determines its amp draw.

The motor's average amp draw and the batteries storage capacity determines flight time.

To answer your question,

We have to know your motor's average amp draw. In other words.>

If you tell us about the motor you have and how hard you push it,

we can give you a more precise answer.
