I have a small crash during the autotune process. Model rolled over left and gently crash without breaking anything. After that, only rear left motor was running.
I tried to fly one more time without autotune but it happened the same.
I have to execute a mission above a forest but I'm not sure the right value to assign to the height of the mission. Should I consider the max trees height (30m for example) and add a security height (10m for example) to be safe.
