Arducopter issue

Hi,

i had posted an issue where my quad was not flying well. Now i got a new frame and started afresh. i have been very careful in setting it up. The quad hovers well on a new battery but then after about 2 minutes it drops altitude. yawing left drops altitude even more. i then give it full power and it still drifts down. attached is the log file. I have calibrated the esc's tried, multiple batteries. bought this new frame. from the logs i can see that the hover position is about 750, which is high. the total weight is 5 lbs (2.3 kg)

How can i solve this problem ?

    • Hi, i dont have battery failsafe enabled? Also i have a low voltage alarm on board and tried two batteries with the same issue.the low voltage alarm did not alert. Both batteries fully charged. 

    • Yes, i am using 3s. I am 100% that failsafe is disabled. I am using the 3dr  power module. I really cant explain what is going on here.

    • i have tried multiple lipos that are fully charged. all experience the same issue. it flies ok for about 2 minutes but needs 80% throttle and then drops slowly event though i have the throttle at 100%
