Hi, I have just upgraded to 3.16, and I have the following issues/questions: Course lock: According to the documentation the directions should be automatically recorded when booting the quad, and then switching to Course Lock would use these recorded directions. However, course lock did not work for me at all. The quad always flew towards its nose when I pushed the forward stick. I had to manually record the direction (landing the quad, switching X1 between Off and CL a few times, and then leaving it on CL). Is this normal? Home lock: According to the docs, the home position is recorded at boot time (if enough gps satellites are found), and this is indicated by the green led quickly blinking. This was the case for me this afternoon, but still, when I flew out of a 10m circle, home lock still did not work. I will do a more careful check tomorrow when my battery is charged again.
