Low-Oil Fuel
All competitors have to use Official ecology fuel( 10%oil Fuel or 15%Nitro-18%Oil Fuel)

Noise penalty system
The low noise bonus system applied till the last fiscal year is abolished, and it changes into a penalty system.

In all rounds .
(1) The noise measured value measured in 3m distance during hovering with the eye level in a starting box is below 85dB(A).
(2) The rotor rotational frequency change under hovering manoeuvre is less than 100RPM from the time of noise measurement.
(3) Judges judged that it was the low noise under aerobatic manoeuvre.

3% demerit mark is given to the player who does not fill the above conditions (1), (2), and (3).

Flight airspace .
The frame of 150 degrees is set up apart from performance airspace, and an airspace judge records all players' flight.
It will consider as a test case in the 2005 fiscal year.
From the 2006 fiscal year, when flight airspace is exceeded, it will consider as the object of a penalty.

After the completion of two official preliminary rounds,the best score will be used to determine
the fly-off competitors.
The top 15 of all competitors then compete in two fly-off rounds to determine the final individual classification.

The matter about a safe flight .

1. In landing to the central helipad in hovering manoeuvre (schedules A and B each 1.2.3) (landing to a central helipad from a starting box is included), when a main rotor blade or a tail rotor blade contacts the ground landing or while [ after landing, ] taking off next, the flight is ended.

2. Wind direction and wind velocity .
When it becomes the conditions applicable to the following items, a game is interrupted temporarily.  Future judgment is based on deliberations of the Jury and the competition director.

A. Wind velocity 8 m/sec continues more than for 1 minute, and a wind direction is a case in front of about 45 degrees or more to a flight path (parallel to a judgment line).

B Even if . wind velocity 8 m/sec does not continue more than for 1 minute, when the wind of 10 m/sec blows frequently suddenly.

C. Even if it is a fair wind (parallel to a flight path), when it is thought dangerous that the wind of 12 or more m/sec of wind velocity blows intermittently, and continues a flight.
