"SPIRIT OF SAM CONCOURS EVENT"

SECTION I - Definitions and Basic Regulations

1. Old Timer and Antique categories are defined as model aircraft which have been DESIGNED, KITTED, or PLANS PUBLISHED prior to December 31, 1942 and December 31, 1938 respectively. Authentication of design is the responsibility of the contestant. Claims made for prior design date shall be authenticated by documented proof (dated photographs, affidavits, etc.). These shall be submitted to a Model Design Review Board (made up of current SAM officers and as appointed by the SAM President) for approval.  These authenticated prior designs will be published as supplements to the rule book, in the form of hand books entitled the Society of Antique Modelers Approved Designs List - Gas Models , and the Society of Antique Modelers Approved designs List - Rubber Models

 
2. Models shall be flown in one of the following categories.
• A.  Antique
• B.  Old Timer Pylon (Defined as a model having a sheet or built up structure holding the wing above the fuselage proper.) See the Approved SAM Designs list.
• C.  Fuselage Models (All other designs including cabin models will be included in this class.
• D.  Old Timer Rubber (fuselage and stick)
• E.  Vintage Special Events.
• F.  Old Timer Hand Launched Glider
• G.  Rubber Scale
3. Antique Category models shall be powered with original ignition engines only and be divided into two events: Fuel allotment Antique (6 ft. minimum wing-span) and 30 second Antique (no size limitations). The 30 second Antique models shall weigh a minimum of 8 oz. Per sq. ft. of projected wing area. This event is limited to non-pylon models only. The use of diesel engines is not permitted in the antique events.
4. Old Timer Fuselage and Pylon models shall weigh a minimum of 8 oz. Per sq. ft. of wing area (projected).
5. Ignition engines are defined as those engines using cam operated points, spark plugs, batteries, and coil (or magneto) to ignite the fuel.
6. Any fuel may be used in ignition engines with the exception of nitromethane, nitropropane, or nitrobenzine. Engine shut-off must be accomplished by the use of and ignition circuit-breaker. No other method of stopping the engine will be allowed.
7. Rubber models must use the same prop design as on original model (folding, single blade, free-wheeling, etc.). Maximum diameter shall be that shown on the plan or 1/3 of the flat wingspan, which ever is greater. No limit on the amount of rubber used.
8. Unless otherwise stated, each contestant will be allowed two (2) models in an event to complete three (3) official flights.
9. Rubber scale event: Models shall be models of an actual large scale aircraft built to requirements of Section I Par. 1. Models may be hand launched or ROG'ed into flight. The maximum duration of flights and the number of flights per event will be determined by the Contest Director. The total time of the flights will determine the contestant's score. There will be no scale judging. Authenticity shall be determined per Section II, Par. 2. The propeller(s) shall be as shown on the plans except when the plan shows a small (nonflyable propeller). The diameter of the propeller can be increased up to 1/3 wingspan. Free-wheeling will be allowed on the props where the plan is dated 1935 or later.
10. Commercial Rubber special event: A rubber power model kitted, published, or authenticated prior to 1943. Maximum wingspan is 36" projected. Model must be flown in it's original size (no scaling) with original dihedral. The rubber motor must be enclosed in the fuselage and the plans must not show a folding propeller. If the prop shaft is shown fixed to the propeller, it may be modified into a free wheeler. Propeller diameter shown on the plan is the maximum allowed; or if no propeller is shown on plan, the maximum diameter is 1/3 of the flat wingspan, whichever is greater. Propeller may be any pitch and must be wood, except plastic may be used if the original model used plastic. No limit on rubber motor size or model weight, but reducing wood sizes and covering material to lighten is not allowed. Strengthening and adding additional spars is permitted. Model must have a landing gear to permit ROG, but the ROG takeoff is at the descretion of the Contest Director, 6 attempts for 3 official flights is the score. Three minute maxes.
11. Unless otherwise stated, the "Builder of the Model rule" as defined by AMA is in effect for all SAM free flight events.

1. A Old Timer or Antique may be modified only in the following was: minor changes to thrustlines, i.e., upright instead of inverted engines; strengthening of structures and provision for dethermalizing. Area and moments may not be changed. All changes must be in the character of the original model, i.e., substitution of sheet balsa fuselage for original builtup structure is NOT approved. Beef up the builtups! Flat air foils may not be substituted for cambered airfoils, NO enlargement or reduction of model size..

1. It shall be the responsibility of the contestant to prove the validity of the model and the fidelity to the design by submitting the actual construction prints to the Contest Director upon request.
2. No modifications may be made which would prevent the model from making normal, unassisted ROG takeoffs. Therefore, no dropping gears, NO VTO, and no catapult devices are approved. Two wheels may be substituted for single wheel gear, but one wheel may not be substituted for two wheel gear.

1. No official records will be established in any of the Old Timer events or categories.

1. All pertinent AMA Safety Rules, not covered above, shall be in effect covering the model, modeler, and equipment.

The following rules apply to SAM R/C competition events and are complemented by Section III, paragraphs 3, 4, & 5 of the SAM F/F rules, and by all AMA rules for sanctioned events, general R/C and safety.

SECTION I - AIRCRAFT DEFINITIONS

1. Old Timer (OT) and Antique categories are defined as aircraft which have been DESIGNED, KITTED, or PLANS PUBLISHED prior to December 31, 1942 and December 31, 1938 respectively. Authentication of design is the responsibility of the contestant. Claims made for prior design date shall be authenticated by documented proof (dated photographs, affidavits, etc.). These shall be submitted to a review board (made up of current SAM officers and as appointed by the SAM President) for approval. These authenticated prior designs will be published as a supplement to the rule book, in a hand book entitled the Society of Antique Modelers Approved Designs List. All powered R/C models including 1/2 A Texaco, must have originally been gas powered (i.e. no rubber models).
2. The contestant must, if requested, prove the fidelity to the original design by submitting to the Contest Director (C.D.) a copy of the original, or authenticated blueprints from which the model was built, or scaled.
3. In SAM R/C, no distinction is made between fuselage (cabin) and pylon designs, nor is a "builder of the model" rule in effect.
4. Aircraft types Explained:
• A.  Antique: A pre-1939 design as defined above, and flown in events which may be segregated by engine sizes and types, known as "Antique" events. Also flown exclusively in the specialized Texaco fuel allotment event. A Pure Antique model is a separate subclass of Antique, which may be powered only by an original ignition or pre-50's diesel engine, and may not be scaled up or down from its original size.
• B.  Old Timer: A pre-1943 design as defined above. Flown in events segregated by engine class sizes and types, known as limited engine run (LER) events. Since an Antique model is also pre- 1943, it may be flown in O/T events, but not vice-versa.
• C.  1/2 A Texaco: Any competition legal O/T or Antique design with an .049 reed valve engine, flown in its own special event, using a propeller limited to 8" or less diameter.
5. All SAM R/C models must weigh a minimum of 10 oz. per square foot of planform wing area, except for 1/2 A Texaco models, which must weigh a minimum of 8 ounces per square foot.
6. All glow and converted ignition engine powered models must have a minimum of 225 square inches of wing area per .1 cubic inch of engine displacement.
7. All models may be modified in the following ways: Minor changes to the thrust line, i.e., upright instead of inverted engines; strengthening or lightening of structures and provision for control surfaces. Foam plastic may not be used as a structural material. Outlines, areas, moments and cross sections may not be changed except for direct scaling, Airfoil sections must be the same as on the original model or plans. Landing gears must be in the same location as on the original model; however, single wheeled main landing gear designs may be modified to dual wheeled main landing gear designs. All changes must be in the character of the original ship. This includes wheel sizes and dihedral, which shall be the same dimensions as the original model when the model is unscaled, or shall be increased or decreased by the same ratio on scaled up or down models.
8. No modifications may be made which would prevent the model from making normal, unassisted rise off ground (ROG) takeoffs. Therefore, no dropping gears (except "Mystery Man" model), no VTO, and no catapult devices are approved.
9. For the purposes of determining wing area of a flying wing, 1/3 of the wing area shall be considered stabilizing area.
10. It is permissible to scale any approved design up or down, except Pure Antique models.
11. For safety reasons, all models except 1/2 A Texaco must have a functioning R/C controlled engine cutoff.
12. Only fixed pitch, non-folding two bladed propellers made of wood, injection molded plastic, or continuous fiberglass strand and plastic shall be permitted.

1. All engines must be of conventional reciprocating piston design. No turbines, Wankels or other non-reciprocating designs allowed. Old Timer and Antique models may be flown with original ignition, converted ignition, deisel, or glow engines as described below. Supercharged or turbo charged engines are prohibited.
• A. Ignition engines are defined as those engines using cam operated points, spark plugs, batteries, and coil (or magneto) to ignite the fuel. Breaker point operated transistorized switching systems are acceptable.
1. To qualify as an original ignition engine, the engine must be of a type first produced prior to 1950, or must otherwise meet SAM engine committee qualifications described in the SAM free flight rules, section III, para's 3, 4, or 5.
2. A converted ignition engine is a glow engine to which ignition points and a spark plug have been added, or a modern (post-December 31, 1949) designed ignition engine. Converted ignition engines are limited to cross scavenged 2 cycle, and to 4 cycle engines only.
•  B. Two Stroke Glow engines are subdivided into:
1. ) Conventional cross scavenged engines.
2. ) Schnuerle or Perry directional ported (PDP) engines.
• C.  Diesel engines are for classification purposes. grouped with other basic types of engines as follows:
1. )  Pre-1950 diesels are considered original ignition.
2. )  Post 1949 diesels and cross scavenged diesel conversions from glow engines are considered cross scavenged glow engines
3. )  All Schnuerle diesels are classed as Schnuerle glow engines.
• D.  Four cycle engines are classed as cross scavenged glow engines if glow ignited, or they may be converted to ignition and grouped with other converted ignition engines. Four cycle engines having exposed rocker arms, and originally manufactured by OS, Saito, Enya, or Kalt prior to 1986 will have only 60% of their actual displacement used for classification purposes. Also, all pre-1950 four cycles will use the 60% rating. All others including all modern enclosed rocker arm engines will be rated at 80% of their actual displacement for classification purposes.
• E.  1/2 A Texaco engines must be Cox reed valve .049's with an integral fuel tank of not over 5.1 cc capacity. These must be basically "stock" engines as typified by the Texaco Jr., or Babe Bee designs. Other Cox reed valve engines such as the Black Widow, or Golden Bee designs are acceptable as long as the larger 8cc tanks are replaced by the 5.1 cc tank, such as found in Cox #1596 conversion kit, containing the smaller tank assembly. The only modifications allowed are: Moving the fuel pickup from the middle to the bottom of the tank, addition of a muffler, and/or addition of a needle valve extension.
2. Engine classes are based on the following displacements;

 

CLASS	CUBIC INCHES
1/2 A	0.000 to 0.049
A	0.000 to 0.200
B	0.201 to 0.300
C	0.301 to 0.650

Original (pre-1950) ignition engines up to 1.2 cubic inches may also be used in class C.
 
3. Tuned pipes, tuned mufflers, or other exhaust attachments which increase engine performance are prohibited. Mufflers which do not increase performance are allowed on any engine..
4. Only engines of the type and specific displacements listed in this section may be used in SAM basic events.

1. Ignition engines may use gasoline and lubricants. FAI fuel (methanol and lubricants only, no nitro or other additives) is allowed.
2. Diesels and glow engines may use any fuel that has not been banned by AMA for safety reasons.
3. 1/2 A Texaco engines may use no gasoline based fuels or additives. They may use only commercially available glow fuel, or any percentage blend of alcohol, nitromethane, propylene oxide, and lubricants.

1. All events are basically climb and glide, with flight scores accumulated at one point per second. Flight time is started at the moment the model is released for immediate takeoff, and ended when it next touches the ground, or some stationary object on the ground.
2. Engine run times are based on either a specific number of seconds, according to some combination of engine types and/or model weight, or by a specific allotment of fuel based on engine type and/or model weight.
3. All events except Texaco have maximum or "max" times beyond which no further flight points are accumulated during any one flight. For these events the total of all official flights is taken for scoring. In Texaco, the single longest flight determines the score.
4. In each event, a limited number of flights, or flight aborts called "attempts" is allowed, during which the contestant must accumulate his official flights for that event. When the official flights are first completed, or attempts exhausted, the entrant may make no more flights, even if some official scores are zero.
5. Allowable attempts and flight maxes are as follows:

 

	ALLOWABLE	OFFICIAL	MAXIMUM TIMES
EVENT	ATTEMPTS	FLIGHTS SCORED	IN MINUTES
LER	6	3	7
Antique	6	3	10
1/2 A Texaco	3	2	15
Texaco	3	best 1 of 2	unlimited


 
6. Engine run times by engine types for Antique and LER events are as follows:

 

	Schnuerle	Cross	Converted	Original
	glow	scavenged	ignition	ignition
Event	engines	glow	engines	engines
LER	18 secs.	23 secs.	28 secs.	35 secs.
Antique	5 sec/lb.	6 sec/lb.	7 sec/lb.	8 sec/lb.


 
7. Engine run time starts when the model is released for take-off, and ends when the required R/C shutoff has been activated and the engine stopped.
8. Fuel allotments are as follows: For Texaco a contest official measures and fuels the engine with 4 cc/lb. of aircraft weight. For 1/2 A Texaco the 5.1 cc fuel tank may be filled by the contestant.
9. In Texaco and Antique events, the measured weight of the model is rounded off to the nearest pound -e.g.: 5 lb. 8 oz. to 6 lb.; and 5 lb. 7 oz. to 5 lb. for fuel allotment engine run purposes only.
10. The CD must insure that everyone has a reasonable opportunity to fly and thus may reduce engine runs/flight maxes as necessary.

1. The following basic R/C events shall be flown at all SAM Championship meets, and will be used as the basis for determining an overall R/C Ignition Champion and an overall R/C Glow Champion by awarding 5 championship points for each first place, 4 for second, etc. down to 1 point for fifth place.

 

IGNITION	GLOW
A. Class A O/T [LER] Ignition	F. Class A O/T Glow
B. Class B O/T [LER] Ignition	G. Class B O/T Glow
C. Class C O/T[LER] Ignition	H. Class C O/T Glow
D. Pure Antique     [original ignition engine, no scaling]	I. Antique Glow     [glow or ignition, scaling allowed]
E. Texaco (ignition engine)	J. Texaco (glow or diesel engine)
	K. 1/2 A Texaco

There is only one Texaco Event -- separation is for championship points only.
 
2.  In local contests, the CD may combine LER classes, and Antique classes and events if there are fewer than 5 entrants in any one class of event.
3. In local and regional events the CD may select the classes he wishes to fly and in such meets may try new concepts as "special events" to determine their practicality. The CD must in this case pre-publish and distribute written contest information stating the events to be flown, and deviations from these rules, and the specific rules for any new events.
4. The CD shall call a meeting of all contestants prior to the start of a contest to inform them of the rules and any changes he designates due to peculiar field conditions. It is the responsibility of the contestant to be aware of all rules for those events in which he is competing.
5. All models must rise off the ground (ROG). This rule may be altered by the CD to permit hand launching only if the field is to rough, muddy, or grassy.
6. The CD will determine fly off rules in case of ties.
7. Only one contestant may fly a particular plane in a given event. He, or another may fly the same plane in other events. Unless otherwise stated, each contestant will be allowed one (1) model in an event to complete the required official flights.
8. All models must land by coming to rest completely within an area designated by the CD. Models landing outside the designated field area will be given a zero score, unless the flight has otherwise qualified as an attempt and the model cannot be safely landed within the designated area.
9. Attempts are defined as follows:
• A.  An attempt is either a completed official flight, or an aborted flight. Therfore, any release of the model in an attempt to launch must be entered on the scorecard.
• B.  An engine overrun, or a flight lasting less than 40 seconds in LER or Antique is automatically an attempt.
• C.  In Texaco and 1/2 A Texaco, any flight under 4 minutes is an attempt unless declared an official flight by the contestant.
• D.  A contestant may voluntarily declare an attempt (abort) to the timer within the specified time of his engine run in LER or Antique, or within 4 minutes in Texaco or 1/2 A Texaco.
• E.  The contestant has 5 minutes to get airborne, from the time he is assigned a timer and a clear frequency. Otherwise he loses his immediate turn at flying but is not charged with an attempt.
• F.  Anyone serving as a timer is an acting contest official and is responsible for minimum knowledge and enforcement of the rules. The timer must monitor the 5 minute time limit to get airborne, record all attempts, official flights, or off field landing, and report any known or suspected rules violations or flight irregularities to the C.D. for resolution.
10. The timer must see the model released to start the flight and must see the model land on the field to conclude the flight score. It is not necessary that he have the model in view at all times during the flight. To prevent loss of a model, binoculars may be used only during a declared emergency to aid the pilot in returning the model directly to the field.
11. Thermal aid equipment, such as thermal sniffers are not allowed.
12. There will be no time limit nor penalty imposed on the landing of a model. However to prevent delays, the contestant must land as soon as possible after a "max" flight is achieved, or an attempt made.

Special events are similar to supplemental and provisional rules as defined on page 2 of the 1994-95 AMA regulations booklet. They may be one-shot trial events, or they may be flown frequently to test their viability as future basic events. The following special events are currently recognized:

A just-for-fun event for R/C and F/F models in which the flyers themselves decide which of the models entered best represents that spirit of imagination, experimentation and craftsmanship which characterized the early days of aeromodeling.

It is an event for those old time models, while not necessarily competitive under current duration based rules, nevertheless reward flyer and spectator alike with the pleasure of seeing them take gracefully to the air.

Rule 1.  Any model which qualifies under SAM rules as an Antique or Old Timer, designed originally for gas powered freeflight or gas flying scale shall be eligible of entry. There are no restrictions on engine size or type used. (This includes electric motors). There are no wing area or power loading requirements.

Rule 2. No documentation, formal judging, or timed flights are required. The models entered in this event are expected to fly at least once during the general contest. The flight shall consist of take-off or hand-launch, climb for altitude, power cutoff, and glide to a landing. It is recommed that this one flight be kept under five minutes and that one or more of the other flyers entered in this event, or the contest director, be invited to observe the qualifying flight. Other flights may be made, as time permits, if the contestant wishes to demonstrate the flight qualities of his model.

Rule 3. A model that is also entered in one of the duration based competitive SAM events need not make a special flight to qualify for the "Spirit of SAM" Concours event.

Rule 4. Models entered in the Spirt of SAM event will be identified with a number assigned by the contest director while they are on display to assist in the voting process.

Rule 5. All participants in the general contest, whether entered in the Spirit of SAM Concours event or not, will be invited to cast a vote, using special ballots provided by the contest director for their choice. In making the choice, such factors as use of appropriate materials, (construction techniques, uniqueness and special interest) of the design, complexity, general workmanship and graceful flight characteristics should be taken into account. Criteria for selection are deliberately vague. Each participant should choose the model which best represents his concept of the "Spirit of SAM."

Rule 6. The contest director shall count the ballots, verify that each model has performed its required flight, and announce the winners. There will be five awards presented at the SAM CHAMPS (first through fifth place) and the Spirit of SAM Concours perpetual award shall also be presented to the first place model. The modeler winning the award will be allowed to keep the perpetual award for one year and be responsible to return the award to the contest director of the SAM CHAMPS prior to the next annual meeting. Should the officers of the Society of Antique Modelers decide to terminate the holding of this event, on an annual basis, the perpetual award shall be returned to the Society.
