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.
