I've been trying to use the in-flight leveling function in my jdrones hexacopter, but can't ever seem to get it to work. After some trial and error, I've come to the conclusion that for some reason, the in-flight leveling only seems to be activated in my APM for 13 seconds - at least the green LED only flashes for that long, and the copter seems to go back to normal flight pretty quick while trying to calibrate it. Any thoughts as to why I'm having this problem and what I might be able to do to fix it?
Interestingly, it does take 20 seconds to arm in-flight leveling mode...
I'm going to try re-installing the firmware and see if that fixes the problem
