Hey all. I went this meeting for a flight everything was good. Then I decided to take some quick pics so I fired up the 40 again.. As it was doing is boot I moved out a little too get the cables in. By the time it was done the green was flashing so I took it up. This time it was a little wobbly and after a minute it stayed to drift more than the usual foot. I let it hover to stabilize but it didn't help.. Winds carried it and it wasn't locked on altitude either. I switched to atti and brought it down. Can you guys chime in as to why it did that?
