A 17AH battery is way too big for any reasonable quadcopter and will be way too heavy. A 5AH battery is around the top end for most quadcopters.

Also your motor input is incorrect. Most BL outrunner motors have way more poles than 2, what motors are you using? Your resistance is too low too.

Your propellers are also too large for most quadcopters. the normal is 8-12" in diameter.

BTW. 10-15 minutes is the longest flight times you'll get on a quad. Yes, people have flown longer but you need a very specific set-up to do that and it will not be very useful for anything else
