Electric Glider Duration and Spot Landing Contest Rule
1. Objective: To compete safely on the longest airborne
durable and spot landing accuracy of electric glider that will be 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 of his own for the entire competition. 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 electric glider.
3.2 There is no limitation of the allowable wing span and the
size of the model .
3.3 The model must be powered by a 7-cell NiMH or NiCD rechargeable
battery. Lithium battery may be allowed provided that the battery
pack has only two slots of cells,
i.e., 2S, with a total voltage of not exceeding 7.4V.
The on-board r/c electronic must draw its power from the battery
pack that also drives the main motor.
4. Contest Rules
4.1 Contest Site.
4.1.1 All contestants must operate their model on a designated
area. Spectators must be at least 20 meters away from the
spot landing area . Pilot must not fly his/her aircraft over the
spectator line.
4.2 Contest Structure.
4.2.1 Individual. A group of maximum 4 aircraft
will be flown in each round. Each round shall consist of ten (10)
minutes after the aircraft is airborne. In the first 40 seconds,
the contestant is allowed to turn on the motor for the aircraft to
gain height. After that the motor must be turned off and the
aircraft should try to stay airborne by exploring thermals.
One minute to the end of current round, the judge will signal the
contestant to land the aircraft and count down also starts. A
contestant should land his/her aircraft as close as possible to
his designated landing spot.
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.
5.2 Contest Director. The CD or his or her representative will
check each aircraft for conformance to specification & 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 based on the airborne duration and spot
landing accuracy. The lowest and highest scores in each round are
0 and 20, respectively, and are non-negative.
6.2 Duration is the time from first airborne to the time the
aircraft landed. If the duration is more than 10 minutes, points
will be deducted from the score, for example, if the duration is
9.78 minutes, the score is 9.78. On the other hand, if the
duration is 10.61, the score will be
(10-0.61)=9.39.
6.3 Points are also scored for spot landing. The distant
between the landing mark and the landed model's nose is measured
and the points are awarded according to the distant; 0 point for
more than 5 meters, 1 point for 4 to 5 meters, 2 points for 3 to 4
meters, 3 points for 2 to 3 meters, 4 points for 1 to 2 meters, 5 points for within
one meter. An extra 5 points will be awarded if
the distant is less than 0.5 foot. The maximum score for spot
landing is 10. If the plane is landed
during the 40s driving period, the score obtained for spot landing
is void.
6.4 Any aircraft that can not be landed normally, the score
will still be awarded according to the rules described above.
6.5 Five points will be deducted if any part belong to the
model fell off, either intentionally or unintentionally, during
flight.
6.6 Two points will be deducted for each second the motor is
still turned on after the initial 40 second motor driving period.
6.7 Under normal circumstance, each contestant will be able to
compete a total of 5 rounds. The final score will be the total of
all points awarded in all rounds.
