3.C2 THE FOUR STICKS
Objective
This task is intended as a small break task between elements of an
overall task.
Description
There are 4 standard kicking sticks set at the corners of a 50m x
50m square. The pilot must kick 3 of the 4 sticks. The first stick the
pilot kicks may be any of the 4 sticks. The third stick the pilot kicks
must be diagonally opposite the first, the second stick may be either
of the two other sticks.
Special rules
- If this task is used to take a time for the purposes of an element
of the overall task then the time shall be taken the moment the
pilot strikes the first stick.
- The pilot may have as many attempts as necessary at striking the first stick.
- Only ONE attempt is allowed at kicking both the second and third sticks.
- There shall be one group of 4 sticks for every 15 competitors in the task.
- On approach to the task, pilots should choose a "free" group of sticks. However if, in the opinion of the
marshals on duty a conflict with another aircraft existed (depending on the overall task, for example if there is
a timing involved) both should kick only one stick and then depart on the rest of the overall task. Both pilots
will then be given the opportunity to have ONE further attempt at this task as soon as possible after the end of
the overall task.
Scoring
The scoring should be integrated into the overall task as NQ. If the pilot fails to kick either the second or third
stick then for each stick then the penalty shall be no more than 5% of the overall task score
3.C6 PRECISION CIRCUIT IN THE SHORTEST TIME (‘Clover leaf slalom’)
Objective
To strike a number of targets laid out in a given order in the
shortest possible time and return to the deck.
Description
4 pylons 2m in height are laid out
- At the corners of a 70.71m square for PF1 and PL1
classes.
- At the corners of a 100m square for PF2 and PL2 classes.
A fifth target is set at the centre of the square.
The pilot enters the course and strikes the target T (strike 1).
At this point the clock starts. The pilot flies around pylon 2 and
returns to kick the stick T (strike 3), he then flies around pylon
4 and returns to kick the stick T (strike 5). This continues until
all four pylons have been rounded. The clock stops when
target T is kicked for the last time (strike 9).
Special rules
- A valid strike on the target T is:
EITHER one where the pilot or any part of the Paramotor has been clearly observed to touch it.
OR when electronic ‘kick stick’ sensors which have been shown to meet the standard tests are used, a valid
strike is one which is recorded by the device.
- To count as a strike, the pilot’s body must be clearly seen to round each pylon and pylons 2 & 8 must be
rounded in an ANTI CLOCKWISE direction and pylons 4 & 6 must be rounded in a CLOCKWISE direction.
- A strike on target 1 starts the clock, a strike on target 9 stops the clock.
- Pilots may have only one attempt at striking each target except for the first and last targets where three
attempts at each are permitted.
- Failure to strike the first or last target or round at least one pylon or touch the ground at any point between
them: score zero.
- The grid may be opened up to max. 100M at the briefing if the meterological conditions dictate.
Scoring
pen pil pen t = t + mv
Where
tpil = the measured pilots time (seconds)
m = the number of missed targets
vpen = the time penalty for each missed target (seconds)
tpen = the pilots time (after penalties for missed targets)
tbest = the best time (after penalties for missed targets)
Q = the task value before normalization
Note: Spreadsheet formulas:
tpen: = t_pil + m * v_pen
Q: = LOG(3 * t_best / (t_pen – t_best + 3))
or
Q: = LOG(3) + LOG(t_best) – LOG(t_pen – t_best + 3)
3.C7 PRECISION CIRCUIT IN THE SHORTEST TIME (‘Japanese
slalom’)
Objective
To strike a number of targets laid out in a given order in the shortest possible
time and return to the deck.
Description
4 pylons 2m in height are laid out on
- On a 50 m x 50 m grid for PF1 and PL1 classes,
- On a 70,71 m x 70,71 m grid for PF2 and PL2 classes.
The pilot enters the course into wind and strikes target 1. At this point the clock starts. The pilot then strikes
targets 2 and 3. He then returns to fly clockwise around target 1 (strike 4), anticlockwise around target 2 (strike 5)
and clockwise around target 3 (strike 6). He then returns to strike target 1 (strike 7), target 4 (strike 8) and target
3 (strike 9). The clock stops when target 3 (strike 9) is kicked.
Special rules
- A valid strike on a target is:
EITHER one where the pilot or any part of the Paramotor has been clearly observed to touch it.
OR when electronic ‘kick stick’ sensors which have been shown to meet the standard tests are used, a valid
strike is one which is recorded by the device.
- When targets are acting as pylons, to count as a strike, the pilot’s body must be clearly seen to round it,
pylons 1 & 3 must be rounded in a CLOCKWISE direction and pylon 2 must be rounded in an ANTI
CLOCKWISE direction.
- A strike on target 1 starts the clock, a strike on target 9 stops the clock.
- Pilots may have only one attempt at striking each target except for the first and last targets where three
attempts at each are permitted.
- Failure to strike the first or last target or touch the ground at any point between them: score zero.

3.C8 PRECISION CIRCUIT IN THE SHORTEST TIME (‘Chinese slalom’)
Objective
To strike a number of targets laid out in a given order in the shortest possible time and return to the deck.
Description
Between 6 and 12 targets are laid out on a course not exceeding 3Km in length. Targets are sticks.
intermediate targets may also be min. 8m inflatable pylons.
The pilot enters the course into wind and strikes target 1. At this point the clock starts.
The pilot then flies the course to strike all the other targets in the given order, a strike on the last one stops the
clock.
Special rules
- A valid strike on a target is:
EITHER one where the pilot or any part of the Paramotor has been clearly observed to touch it.
OR when electronic ‘kick stick’ sensors which have been shown to meet the standard tests are used, a valid
strike is one which is recorded by the device. OR if a target is an inflatable pylon, when the pilot
crosses in the correct direction the line which defines when a pylon is passed correctly. (S10
5.7)
- A strike on target 1 starts the clock, a strike on the last target stops the clock.
- Pilots may have only one attempt at striking each target except for the first and last targets where three
attempts at each are permitted.
- Failure to strike the first or last target or at least two of the intermediate targets, or any inflatable pylon,or
touch the ground at any point between them: score zero.
Scoring

Where
tpil = the measured pilots time (seconds)
m = the number of missed targets
vpen = the time penalty for each missed target (seconds)
tpen = the pilots time (after penalties for missed targets)

Q = the task value before normalization
Note: Spreadsheet formulas:
tpen: = t_pil + m * v_pen
Q: = LOG(3 * t_best / (t_pen – t_best + 3))
or
Q: = LOG(3) + LOG(t_best) – LOG(t_pen – t_best + 3)
Note to Director: This task is ideally suited for sites where there are physical features which obscure a direct view
from one target to the next.
New text
None.
Reason
Slaloms which require kicking sticks are dangerous for pilots and their aircrafts nowadays. These tasks should be replaced by task from World Paramotor Slalom Championships: a triangle, and figure 8, which are possible to perform with pylons and timing gates.
