What are typical load factors that UAVs are designed for?
I'm currently designing my UAV for a ultimate load factor of 10 which seems plenty sufficient for it's mission, surveillance.
The greatest loads I can expect are from gusts and a very bad landin

Hi all,
Yesterday I went to the field to do my 1st flight and autotune the PID gains of a custom frame quadcopter.
The configuration is 'X' and I use Pixhawk with APM Copter V3.3.3. 30A ESCs with D3530/14 motors, 7x4'' 3 bladed props and a 4S 5000mA Li
Greetings,
I have been developing a quadcopter from scratch for a while and I am really at the edge at the moment. The reason is that I just cant find the correct values which will make it stabilize and Control Theory is not my background.
