OFFICIAL RULES FOR PEE WEE 30
DEVELOPED AND PRESENTED BY THE SAN DIEGO ORBITEERS
EFFECTIVE: JANUARY 1, 1987

1.0   MODEL DESCRIPTION AND CONFIGURATION:

1.1   DIMENSIONS:
No part of the model shall exceed 30 inches when it is in the assembled condition. This limit includes all hardware such as spinners, hooks, tip plates, etc., although a de-thermalizer fuse may extend outside the 30 inch limit.

1.2  POWER SOURCE:
The model shall be powered by a single Cox Pee Wee .020 reed valve engine.  Any fuel permitted by AMA rules may be used.

1.3 LANDING GEAR:
The model must be equipped with a fixed two wheel landing gear which shall be capable of supporting the model unassisted for at least 30 seconds in the takeoff position. The wheels shall be no less than 1 inch in diameter.

1.4  MATERIALS AND TYPE Of CONSTRUCTION:
The model may be constructed of any materials or combination of materials without restriction.    Stick and tissue, built-up sheet, or solid balsa models are all permitted.

1.5  MINIMUM WEIGHT:
The minimum weight of the model, assembled, ready to fly without fuel and fuse, shall be 100 grams (3.53 ounces).

1.6  MECHANICAL OR ELECTRONIC DEVICES:
Engine run timers, V.I.T. devices, flappers, folders, auto-rudders, gear drive propellers and similar performance enhancing devices are specifically prohibited.  Mechanical or electronic dethermalizer timers may be used but must be of the single function type.

1.7  REGULATION OF ENGINE RUN:
The engine run shall be regulated by a metered fuel system such as an eyedropper, a teflon glue tip, tubing, restricted tank volume, etc.

2.0  TIMING OF FLIGHTS:

2.1  OFFICIAL FLIGHT:
An official flight occurs when the model remains in flight for 40 seconds or more.

2.2  UNOFFICIAL FLIGHT:
An unofficial flight occurs when the flight time is less than 40 seconds.  In Pee Wee 30, f'lights of less than 40 seconds may be declared official at the option of the contestant.  The contestant's decision most be made immediately and cannot be reversed later.

2.3  NUMBER OF FLIGHTS:
Each contestant shall be allowed a total of six attempts to make three official flights over 40 seconds.

2.4  ENGINE RUN:
The length of engine run after the model is released for flight shall have no maximum limit, however, all engine runs of less than 15 seconds shall be recorded as 15 seconds for the purpose of flight scoring.
A .   Engine run time shall be recorded in whole seconds with any fractional seconds rounded up to the next whole second.  (Example:    15.1 = 16 seconds)

2.5  FLIGHT TIME:
120 seconds (2 minutes) maximum. See below for scoring of flights and flyoff flights.
A.  Flight time shall be recorded in whole seconds with any fractional seconds dropped to the previous whole second (Example: 107.9  = 107 seconds)

3.0  SCORING OF FLIGHTS:

Both engine run and flight time must be recorded by the timekeeper.   

Each official flight shall be given a score that is calculated by dividing the total flight time in seconds by the engine run in seconds and multiplying by a factor of 100 as follows:

    (Total Flight Time  ÷  Total Engine Run)  x  100  =  Flight score

A perfect "MAX" score shall be 800 points as follows:

     (120 Seconds Max   ÷  15 Seconds Engine Run)  x  100  =  800 points

Other Examples:

(120 Seconds  ÷  19 Seconds )  x  100  =  631 points
(106 Seconds  ÷  15 Seconds)  x  100  =  706 points

A. Flight scores shall be calculated in whole points with any fractional points dropped.

(Example:   706.67  =  706 points) 

3.1  RISE OFF GROUND (R.O.G.) TAKEOFFS:
At least one official flight must R.O.G unassisted off both required wheels.  Should the contestant fail to record an official flight that began with an R.O.G. take-off, only his or her first two official handlaunch flights will be counted as the final score.

3.2  FLYOFF FLIGHTS:
When the total score of three official flights equals the maximum possible (2400 points), the contestant may attempt additional flyoff flights to break a tie score.  The engine run for flyoff flights shall be scored the same as the first three official flights.  The maximum flight time shall be increased in 30 second increments until a non-perfect score is recorded.  The contestant must maintain a perfect maximum flight/minimum engine run string to continue.

Examples

1.          (150 Seconds  ÷  15 Seconds)  x  100  =  1,000 points
Contestant may continue to 180 seconds flight, etc.

2.          (150 Seconds  ÷  16 Seconds  x  100  =  937 points
Contestant receives score of 937 points and his or her total score is added up.

A.  All flyoff flights must R.O.G. unassisted.

B.  All flyoff attempts are official flights regardless of duration or score.

4.0  GENERAL:

All "General" and "Free Flight, General" rules from the latest edition of the official Model   Aircraft  Regulations (AMA Rule Book) shall be applicable unless specifically modified by these rules for Pee Wee 30.
