Some questions about Multiwii 1.9

Hello,I have a few questions about the PID in Multiwii v1.9. In Figure 6 are sections that do not know what they mean. I do not know what happens when you change them.Even when my copter flight fast forward and try to straighten it, it's not. Then the copter crashing down and it got turned LEVEL.Thank you for your answers.

1) you do not need LEVEL (or ANGLE/HORIZON) for first flights/basic PID tuning. Start with gyros, use autolevel only when copter flies on gyros very well
2) upgrade your software. Current multiwii version is 2.2
3) figure 6... ? What's that? PID tuning?

Also, did you read about gyro calibration (hold still for few secs), did you calibrated acc?

I do not know exactly what they mean individual areas of the picture. Also, I do not know why my copter flies in the LEVEL as I wrote.

I replayed firmware to v2.2 and problems with crashes and uncontrolled flight was not. When you fly forward and stop control and the copter stops and falls back. I would like to somehow minimize the forfeiture, but I do not dare to change the PID settings.As for the altimeter, the me too does not work enough height varies.

"When you fly forward and stop control and the copter stops and falls back."

I guess that angle/level "D" is too high, would yield this behavior. This said, I can't believe you tried to fly anywhere other than a hover with an untested aircraft and newbie pilot. I never "broke out of the box", so to speak, for maybe 50 or so, flights and hundreds of adjustments.

As i already suggested... Do NOT fly with any other features enabled (baro, acc) until your copter does not fly fine in gyro-only mode.

I know, but then when I turn off Level so that I can not control it. I fly model airplanes and in this I am a beginner. So without acc afraid to fly.

Learn then. You can't buy expierence... And turning on all sensors won't give you working copter.

Today I tried to turn off the ACC and flew without stabilization. I have to admit, it's easier than I thought. Just do not know if it is correct that the power-off acc no Copter stabilizes. I think flying is better to fly only on gyro and if I want to stay around and shoot camera so I turn LEVEL. Or is it different?
