Slope Combat Rule
1. Objective. To recreate the excitement of aerial
combat in enjoyable, safe competition that will be interesting for
spectators and challenging for the contestants.
2. General. The R/C flier, his plane and equipment shall
apply to this event, except as noted herein. There shall be no
limitation on the number of controls. The contestant shall be allowed
only one (1) model per round, but may switch to an alternate model of
his choice for any following rounds. The builder-of-the-model rule does
not apply for this event. All models flown must be safety inspected by
the Contest Director or a CD appointed representative prior to
competition.
2.1 Consideration of safety for spectators, contest
personnel, and contestants is of the utmost importance for this event.
Any conduct by a contestant deemed by the CD to be hazardous will be
cause for immediate disqualification of the contestant from the event
at the discretion of the CD.
3. Model Aircraft Requirements.
3.1 The model must be an all foam combat slope glider.
3.2 The maximum allowable wing span shall be 49 inches.
3.3 Wings shall have a plastic foam leading edge at
least 1 1/2 inches wide, measured chordwise, at any point on the wing.
The wing leading edges may be covered with film covering material,
vinyl tape, fiber reinforced vinyl tape or any combination of the
three. Wood, metal, solid plastic, carbon fiber, kevlar or any resin
impregnated fiber material on or in the wing leading edges will not be
permitted.
3.4 Wing spars of any non-metallic material are
permitted, provided they do not violate the provisions of item 3.3
above (more than 1 1/2 inches away from leading edge at any point along
the span). Maximum total cross sectional area for spars shall not
exceed 3/4 sq.in. Moveable control surfaces at the wing trailing edge
(ailerons) will not be considered a part of the total spar cross
section.
3.5 The fuselage may have longerons provided their total
cross-sectional area does not exceed 1/2 sq.in. area. The fuselage may
be covered with film covering material, vinyl tape, fiber reinforced
vinyl tape or any combination of the three. Wood, metal, solid plastic,
carbon fiber, kevlar or any resin impregnated fiber covering material
on the fuselage will not be permitted.
3.6 A maximum flying weight of 3 pounds shall be in
effect.
4. Contest Rules
4.1 Contest Site.
4.1.1 The combat box shall consist of the maximum usable
length of the slope and it's lift band with the pilots and judges
located in the normal pilot's area for the particular site. Spectators
must be at least 9 meters behind the edge of the slope . Any pilot
whose aircraft crosses the spectator line will receive no score in, and
be disqualified from, that round.
4.1.2 The CD shall determine if lift is adequate for
competition and may interrupt competition at the conclusion of any
round until lift improves and he or she determines that competition may
commence.
4.2 Contest Structure.
4.2.1 Individual. A group of three (3) to ten (10)
aircraft will be flown against each other in two (2) non-elimination
rounds. After each pilot has had the opportunity to compete in two (2)
rounds, the scores will be totaled, with the six (6) highest scoring
contestants, still capable of competing, advancing to the final round.
The top three scores of the final round are the winner and runner-ups
of the contest.
In the case of a point tie in the final round, the total
of the first two (2) rounds will be used to determine the winner of the
tie. If this also results in a tie, the tied pilots will duel to the
last flying in a round of unlimited length to determine the winner
(fly-off).
4.3 Round Duration. Each round shall consist of ten (10)
minutes after the first aircraft is airborne. If a contestant crashes
at any time during the round, an unlimited number of relaunches are
allowed within the ten (10) minutes, provided the aircraft is down in
an area which allows it's safe retrieval. No repairs may be made until
after the conclusion of the round.
4.4 Change of Aircraft. During a round, no change of
aircraft is allowed for any reason. In between rounds, the contestant
may freely choose from any aircraft available to him.
4.5 Interround Safety Inspection. The CD may, at his or
her discretion, reinspect any aircraft that he or she suspects may have
been made unsafe for flight during an earlier round. If the CD
pronounces that aircraft as unsafe, it will not be used for later
rounds. The pilot of the aircraft removed may make field repairs and
resubmit the aircraft to the CD for inspection. The CD is obligated to
inspect an aircraft resubmitted for safety inspection as soon as the
aircraft is presented to him or her. If it passes inspection, the
airplane is immediately available for use. The judgment of the CD on
safety matters cannot be protested.
5. Contest Officials.
5.1 Judges. There will be one (1) judge for each
aircraft flown. Fellow pilots may act as judges, and will be rotated
each round so that any one judge will not judge the same individual
more than once. Additionally, there shall be a CD for each event. Each
aircraft's judge will register points gained by the aircraft being
judged, according to Section 6. The judge will report the score to the
scoring personnel at the end of the round. Determinations of judges
shall be considered final and may not be protested. The individual
judge scoring any plane confirmed as having crossed the spectator line
by themselves or any other judge is to inform the pilot of his
disqualification for that round and have him land immediately, and the
pilot will score zero (0) for the round, regardless of accrued score to
that point.
5.2 Contest Director. The CD or his or her
representative will check each aircraft for conformance to size &
safety requirements, use the start signal when the first aircraft is
airborne, and use the end signal at the end of ten (10) minutes flight
time. The CD or his or her appointed scoring personnel shall also tally
scores from the judges for each individual (or group) in the
competition.
6. Scoring
6.1 Points are scored by causing the opponent's plane to
strike the ground and cease flight after a mid-air collision (a kill).
No matter who initiates the engagement, the plane that remains flying
after such an event shall gain three point. The one that is grounded
score zero point.
6.2 Mid-air collisions that do not result in an aircraft
striking the ground and ceasing to continue flight (a kill), will net
one point for each pilot.
6.3 Kills shall be verified in one of two ways by the
victorious pilot of an engagement:
a.) The victorious pilot must be able to execute a
single, 360 degree roll and return to normal flight.
b.) The victorious pilot must be able to execute a
single 360 degree loop and return to normal flight.
