Welcome to MultiRotorForums.com!!
When it did fly it didn't have an issue with lifting it at all. Like I mentioned before, this morning first flight of the day, plugged it in and let it go through its warm up steps, gain satellites and mark home position. Started motors and took off without any issue. I flew it to maybe 30 or 40 feet off the ground hovered no problem brought it lower and maneuvered around a bit and then that's when the issues started happening again, same as yesterday. Slowly just started dropping.
checking to see if the batteries are hot is always useful when having problems like you are experiencing....if they were very hot then they might be part or all of the problem. you might have one cell with very high internal resistance that is buggering up the whole pack and bringing down the helicopter.
