1. GENERAL RACE PROVISIONS
These provisions cover the general formats for all classes. There are differences from
class to class. Many of the items listed here and in the specific racing classes are being
held to the honor system. We want to keep the fun aspect in racing without feeling like we
have to over manage these rules so please read all information carefully.
1.1
AMA membership will be required and proof will be verified.
1.2
The current AMA safety code will be followed.
1.3
Event will be a two-pylon course.
1.4
All planes must comply with the current AMA safety code.
1.5
be registered per class.
Backup airframes will not be allowed. This is on a per event basis. Only one plane can

both the Sport and Super Sport classes,
Pilots may register for all classes if desired. However, the same airframe may not race in
1.7
Bracket classes, but not both Bracket classes. Please refer to the specific classes for
more information.
Planes that fly in the Sundowner and Sport Quickie classes may also race in one of the
1.8
classes only. See specific class rules for more information. All fuel left over from an
event will be held by a member of the race committee and will be carried over to the next
race.
Fuel will be provided by the race organization for the Sundowner and Sport Quickie

Propellers will not be provided for any of the current classes. See specific class rules for

control surfaces and clevis' and control rods/horns are secure, props are the correct size
where applicable, fuel is the correct type where applicable and that the airframes and
engines are in compliance as described in the specific racing classes. Any noncompliance
found during inspection may result in disqualification if it cannot be remedied
before the start of the first heat of the day.
Planes may be inspected prior to racing. Inspections will include verification that the

will be asked to come to the briefing with their aircraft. Sundowners will be asked to have
the canopy off for the inspection.
Inspections of aircraft will occur immediately following the pilot and safety briefing. Pilots

needed). There will be no flying behind the dead line.
All pilots, callers and anyone else considered to be “on the course” or in front of the

Any pilot not in the air after 90 seconds will be signaled as a “No Start” and will not be
allowed to take off.
All takeoffs will be roll on ground. Pilots will be notified that the heat is starting and, at the

At the end of 90 seconds, the starter will signal “go” and the race will begin. The starter
1.20
planes will be timed individually.
Official timing of the heat for all planes will begin at the “go” signal. From that point, all
1.21
meet this requirement is a jumped start and will result in disqualification for the heat.
Loops to avoid jumping the start are not permissible. Pilots who find they are about to
jump the start can execute a sharp left turn and circle back to the start/finish line or pull
straight up, as long as the airplane does not cross the start/finish line before the “go”
signal. Making a loop or turning right toward the flight line or any other maneuver that
results in a safety violation may result in a disqualification for the heat.
At the “go” signal, all aircraft are required to be to the left of the start/finish line. Failure to

Entry fees will be $10.00 for all classes. Entry fees will be on a per plane basis.

Entry fees collected for each race will be distributed in the following manner:
1.27.1
40% of the entry fees collected will be given to the host club of the event.
1.27.2
costs incurred including the cost of fuel.
10% of the entry fees collected will be held by the racing organization to cover any

For example, if there is a total of 20 entries in all classes that equates to $200.00 in
1.27.5
For example, if 8 of the 20 entries are in the Sundowner class, there would be a total
of $80.00 received from that class. So 50%, or $40.00, will be given to the winners in
that class.

If a cut occurs, the pilot will be awarded 1 point for the heat. 2 or more cuts in a heat will
result in a 0 score for the heat. 0 points will be awarded due to a “Did not start” or “Did

CANNOT be done.
Also note that the models that qualify for the Sundowner class can also race in one of the
bracket classes, (Sport or Super Sport). If the pilot wishes, the plane may be entered in
only one of the bracket classes. If an airframe is raced in one of the bracket classes, it
must continue to be legal while running in the Sundowner class.
