What is the concept of flight box in pattern flying ?

Is there a box physically drawn on the ground or are there people who moniter the box like in pylon ... the people with flags ...

Or is it just a virtual box for the judges ?

What happens if you go out of the box ?

Next question is : Is there any bonus for using scale planes ? extra 300 , ultimate bipe etc ...

Next Question : If a piece of covering flies of the aircarft ... even then the pilot is disqualified ?
as i read somewhere that if any part drops ...it results in disqualification.

next question : Is nitro allowed in the contest ?

next question : suppose i took off from right to left because of angular cross winds ... after performing half the seq.. the wind direction gets opposite and my head wind and downwind directions change. In this case will i make a dummy pass to crrect my manevours ? Will i land according to the orignal position (right to left) or according to the new direction (left to right) of upwind ?

Looking forward for these answers ..
