Hi
I found that my copter makes an accelerator leveling at every power up.
This is a problem!
The cause is that then at every start up I need a very flat area for leveling. But I do not have this very flat area. So I bought a very little water level to allign it manually (Stick to left down for 15 sec). This takes time...
But way to I need to do this at every start up? If I do it once it would be good enough isn't it?
I found that a very good leveling reduces my drift problem to a very little amount.
thank you and regards from Austria

Accelerometers are calibrated just once when you command "level" either from CLI, mission planner or with the 12 second disarm-command at the field. Only gyros are calibrated every time at the first arming after startup, and you only need to have the copter still (not level, it doesn't matter - just don't move it) when the lights cycle. Then it's ready for business.
You have to manually level it. You can do it in the field by disarming for 10+ seconds. Watch the for cycling lights.
You can also auto-level in the air. See the wiki and only do it in still air.

Copter makes a gyro initialisation and baro initialisation on every motorarming or startup (leds flashing). It doesn't level the accelerometers automatically.
