Disco wont keep altitude

[quiggd]

When I take off it doesn't seem as steep a climb as it used to. When I reaches cruising altitude and I turn it is always losing altitude until in crash lands.
Any suggestions appreciated as I'm very much a novice
Thanks

I've re-charged, recalibrated and took the drone out again today same thing, took off did it's initial turn and then wobbled. Slowly come back to the ground and crash landed (fairly gently) in the grass infront of me. When I checked it over all seemed fine but one of the wings had come loose. Could this wing coupling be the issue?

Do you think the battery might be weak? What was the voltage before the flight and after?

I dont think so but I'll have to get a multimeter to measure the voltage. I'm not seeing anything from the battery life to suggest anything unusual from thr battery.
