HI- Ive been having a blast with my new quad but:
Question 1: there seems to have a tendancy to lose altitude when any yaw is introduced. Granted, it's not extreme, but I had expected it to maintain altitude more exactly than it does. Is this a normal behaviour or one that can at least be addressed with some tuning, and if so, what values would one adjust to achieve it?
Question 2: Should I add a sonar unit for greater accuracy? Most of this type of flying is under <30m, which as I understand it, is the floor for the barometric accuracy while the sonar is accurate to ~10cm whiile under ~ 30m?
Please tell me if these assumptions are incorrect or my expectations too great.
Thanks in advance,
