SBRCM QUICKIE
RACING RULES
OUTLINE
PROPOSAL FOR .25 SIZE RACING
As discussed at the previous monthly meeting there seems to be a
desire to hold some races again, but not using the AT6 Texan .15 size as in the
past. As there is a thriving class of Quickie 500 planes racing with many clubs
taking part and a national championship event, it would seem sensible to start
on the lower rung of that ladder. We could put together a set of rules to keep
participation easy and within reasonable cost using the following proposal:
1. Airplanes to be ARF'S and of Quickie 500 size.
2. Engines to be .25's with the stock muffler supplied.
3. Prop size and make to be same for all competitors.
4. Fuel to be 15% Nitro and supplied by organizers.
5. Max revs to be checked on start line at a number to be
decided.
These simple to administer rules should level the playing field in
order to ensure a lot of fun. ARF Quickies are available from several sources
including Tower and Model Tech for about $120 and the motors can be purchased
from $55 to $85.
As with all things, some organization is required and people will
be needed to put on the events.
In order for our members to compare how other clubs have organized
pylon racing, Valley Flyers at Sepulveda Basin’s Apollo Field sent us the
following guidelines they use. These rules are more detailed than we want to
use, but there is some technical data that we could “cherry pick” for ideas. If
you have trouble getting to sleep, you can also go to the Academy of Model
Aeronautics web site (www.modelaircraft.org/publications.asp
). Under the tabs “Publications” and “Competition Regulations,” you can read
the AMA racing rules. Sleep will quickly follow!!! Please review all the
racing info and discuss it with other members at San Lucas Field this weekend
and at the club dinner so a decision can be made at the March meeting on how
SBRCM will race.
1. GENERAL INFORMATION, OBJECTIVE & INTENT
This class will utilize the AMA Rule Book specifications for 424 - 428 -
Q-500 Sport and Q-500 airframes with the modifications as noted below in
paragraph 3. Engines are .25 size or under as per the approved engine list
noted below in paragraph 4.2. must use APC 9x6 props. (will be supplied at the safety check and must be used
for all racing). Races will be run on the AMA three pole
course. The purpose of the Slow Quickie racing class is to provide a fun and
inexpensive class of pylon racing designed primarily for the entry-level pilot
while still providing plenty of enjoyment and fun for the more advanced pilot.
It is clearly intended the plane speed in this class be substantially and
distinctively slower than the AMA/APRA 424 Quickie 500 class. The spirit of
this class is to focus on developing entry-level pilot skills and NOT on
plane speed or performance enhancements. It is intended when a pilot no longer
feels challenged in this class, wants more speed or prestige, that he/she move
up to a regular AMA/APRA Q-500 class using the .40 size engines.
2. Air Frame Specifications: Same as AMA Rule Book under
classes 424 - 428 - Q-500 Sport and Q-500 with the following added restrictions
and/or modifications: No composite wings or tail feathers allowed.
Fiberglass fuselages are permitted. Minimum dry weight is 3lb. 4oz.
Fuselage: Minimum height of 3.5 inches and a minimum width of 2.875 inches.

Q-500.
3. Engine Rules: Same as AMA Rule Book under
paragraph 4.16. 424 - 428 - Q-500 Sport, Q-500. In addition, any and all
porting, polishing, reshaping, re-sizing or in any manner altering the

contest may enter the event, at the discretion of the CD, with an engine
not listed above in paragraph 4.2 and not subject to the Engine Claiming Rule
as described below in paragraph 4.4 however, the engine entered may NOT provide
any performance advantage relative to the approved engines listed above in
paragraph 4.2. Final decision on engine eligibility to compete in this case
rests solely with the CD. This exception will be allowed to the new pilot for two
contests only.
4. Muffler: Baffles may be removed, otherwise the
rule is the same as in the AMA Rule Book under paragraph 7, subsection 424 -
428 - Q-500 Sport, Q-500. No tuned mufflers or tuned pipes.

allowed. Props will be supplied at
the safety check and must be used for all racing.
7. Illegal equipment: The CD may inspect a
registered owner/pilot’s equipment at any time during an event. If any
equipment is determined to be illegal, the owner/pilot will immediately be
disqualified, sent home for the day and forfeit all awards, prizes and points
previously earned during that contest.
8. Registration Numbers: Same as AMA Rule Book,
paragraph 16, event 422 - 424 - 428 Q40, Q-500 Sport, Q-500.
9. Heat Winners: The winning aircraft from
each heat will be asked to restart at the flight line. With the engine at
high throttle, high throttle trim, with carburetor at full open and the needle
valve setting used for the race, the RPM will be checked. Any engine that
turn more than 13,500 RPM will be disqualified from that heat and receive
"0" points.
10. The CD IS THE FINAL
AUTHORITY AS TO EQUIPMENT COMPLIANCE WITH THE RULES AS WELL AS ALL OTHER
DISPUTES OR PROTESTS THAT MAY ARISE DURING A CONTEST.
Pilot:
This
class is intended to introduce pylon racing to non-experience pilots
wanting to race. For pilots with no pervious racing experience. This
class is a stepping-stone for learning three pylon racing with the same trainer
used for learning to fly, and moving on to faster aircraft.
AIRCRAFT:
The
aircraft must be a high wing tricycle gear “STOCK” ARF trainer intended for .40
size engines. The following modifications may be made:
1. The wing may be bolted on.
2. Trainer may be recovered so
long as it is still recognizable as an ARF trainer.
3. The engine mount and the
hardware used to attach the engine mount may be non-stock.
4. An antenna tube may be
used.
5. Repair of previous crash
damage is allowed.
REQUIRED EQUIPMENT:
1. The fuel tank need not be
stock, but must have at least the fuel capacity of the original tank.
2. Three wheels at least as
large as the original wheels. No tire modification is allowed.
3. Any engine either two or
four cycle may be used. A muffler must be attached.
4. Propeller APC or Master
Airscrew 10 X 6 must be used for the race.
5. Spinner or AMA safety nut
must be installed.
6. Be able to stop the engine
by radio or demonstrate an idle slow enough that an unrestrained aircraft does
not move.
7. Have separate controls of
all three axes and engine of the aircraft.
8. Pilots AMA number must be
on the right wing minimum 1 in. high, or on an AMA sticker affixed to the
inside of the aircraft. Washable poster paint may be used to temporarily apply
numbers or change the color schemes of like aircraft.
RACING:
1. The racing will be
conducted on the same course and generally in the same manner as Three Pylon
Racing.
2. All aircraft will be
checked for construction, and radio equipment installation during the safety
check prior to racing. Bring your aircraft to the safety check with the wing
off.
3. Aircraft will be launched
in a manner to try to avoid ground collisions and may be anywhere behind the
start finish line so long as safety is not compromised.
4. Winning aircraft of each
heat will be required to restart at the fight line. The engine at high
throttle, high throttle trim, with carburetor at full open, and the needle
valve setting used for the race, the RPM will be checked. Any engine that
turns more then 13,500 RPM will be disqualified from that heat and receive “0”
points.
5. You may use any fuel of
your choice. (No fuel will be supplied)
6. Anyone who has not previously
flown in a three pylon race from “on” the course, will only be required to fly
eight laps until that pilot has won a heat race where at least three planes
finished without “cuts” or the Contest Director determines that the pilot will
be competitive flying nine laps. At which point the pilot will fly nine laps
for the rest of the race day. If this first time pilot wins this first race,
they will fly ten laps at the next race.
7. At the second and there
after three pylon race, you will only be required to fly nine laps until that
pilot has won a heat where at least three planes finished without “cuts” and
then be required to fly ten laps from then on.
8. Trainer boxes and
instructor/callers may be used for landing and takeoff. However, if the
instructor/caller is forced for safety reasons to “take over” during the race,
the instructor/caller should return control of the aircraft to the racer as
soon as possible or at least by the next pylon 1 or pylon 2.
9. Heats may be filled to
assure that the most number of racers are in each heat, without regard to a
previously determined matrix.
10. Different pilots may fly
the same aircraft.
ANY AIRCRAFT NOT COMPLYING WITH ABOVE REQUIREMENTS MAY BE ALLOWED TO COMPETE AT THE DISCRETION OF THE CONTEST DIRECTOR, IF HE DETERMINES THAT THE NON-COMPLYING AIRCRAFT HAS NO SPEED ADVANTAGE OVER COMPLYING AIRCRAFT
