I have my arducopter set up in the + configuration and have tried to level it and so far no real success. when i think i have it i connect to the mission planner and the horizon is always off. Would it be better to level it using the mission planner rather than a level?
Also being new to flying quad would the X configuration be a bit easier, right now the quad is very aggressive in its response to control inputs, even though i am using a fair amount of expo on the controls.
Any thoughts would be appreciated
Yes, just level it with the MP. We don't recommend expo on the controls.
Make your controls 1 to 1 with the controller. There is the rate gain and a stabilization gain that the MP defines. The Rate is how well the controller reacts to where it is. The Stabilization is how well it gains to how it should be at a given (frame reference). In a way it is a dual reacting PID.
Yes, you could reduce the stabilize P value and that will make it tamer. The issue that you may find though is that stabilize controller is also used by the higher level controllers (like loiter) so if you soften the response for yourself, you'll also soften it for the loiter controller and it could have troubles.
