Hi, I am the Pampa Rules Committee Chairperson and have an important
message for all OTS flyers and contest directors. The new Pampa reference
manual that has just been published has one blaring ommission. A new rule
passed recently giving five bonus points to diesel flyers! Since it was
not included in the reference manual, I am including it here, so that you
can copy and use these rules for upcoming contests.
Here are the Pampa OTS rules completed:
1.0 Applicability. All Pertinent AMA regulations (see sections
titled Sanctioned Competition and General in AMA rule book), the General
control Line Rules and CL Aerobatics rules shall be applicable except as
specified below. Any deviations from the above or those specified below
should be clearly spelled out in contest advertisements.
2.0 Philosophy. Old Time Stunt offers stunt fliers an additional
event intended for enjoyment, for more relaxed competition and for nostalgic
recreation of the era which led to modern stunt. Because its figures are
simpler than those required for modern Precision Aerobatics, Old Time Stunt
may attract new fliers to CL aerobatics events and competition. Above all,
the event should be fun.
3.0 Model Requirements. The model must have been designed, published
or kitted prior to December 31, 1952. Eligible published designs must have
been published with a cover date prior to Dec.31, 1952. The contest director,
at his discretion, may require proof of model eligibility for Old Time Stunt.
Proof of eligibility lies with the contestant. Challenged contestants may
show dated published plans, magazine construction article, dated photographs
and/or letters of confirmation of the date of the design. Plans of un-kitted,
un-published designs must be made available to PAMPA membership.
3.1 Allowable Modifications
22.214.171.124 Tailwheel. A tailwheel may be added to those designs
which originally had a skid, providing the model's angle of attack (on the
ground) closely approximates the original design.
126.96.36.199 Landing gear. Landing gear material may be changed. The
landing gear length need not exactly duplicate the original, providing the
models angle of attack (on the ground) closely approximates the original
design. Landing gear must exit in the same location as the original design.
It shall not be relocated to provide for perceived advantages in ground
3.1.2 Adjustable leadouts
3.1.3 Adjustable tip weight
3.1.4 Structural changes to strengthen the aircraft.
3.1.5 Control ratios and control mechanism location.
3.1.6 Building material substitutions (hinges, glue, paint, covering
material, landing gear material, etc.)
3.1.7 Use of muffler pressure and uniflow fuel tanks.
3.1.8 Trim tabs.
3.1.9 Fuselage width may be modified to accommodate commercial
two-inch (2") fuel tanks and allow them to be replaced or serviced.
3.1.10 External doublers may be changed to internal, and doublers
may be added to any design without penalty.
3.2 No Modifications, other than those listed above, shall be permitted.
Any modifications (other than those listed in section 3.1) which, in the
opinion of the judges or contest director, significantly change the appearance
and/or performance of the aircraft as originally designed, shall be grounds
for disqualification; to: change of airfoil, change of moments, rudder articulated
by control system, change of asymmetry or symmetry, size, etc. Drop-off
landing gear will not be permitted (Note: Where drop-off gear was a feature
of the original design, contestants should preserve the appearance and location
of the original gear, but must disable its drop-off function for competition.)
4.0 Builder of the Model. The BOM rule shall not apply to the
Old Time Stunt event.
5.0 Appearance Points. Appearance point shall not apply to the
Old Time Stunt event.
6.0 Flight Pattern Points. 25 flight pattern points will be awarded
flights in which all maneuvers are attempted or completed in the correct
sequence. Pilots may omit maneuvers and remain eligible for FLIGHT PATTERN
POINTS providing he/she notifies the judges before each flight of those
maneuvers which will be omitted, and execute the remaining maneuvers in
the proper sequence. A crash shall not be grounds for deduction of flight
pattern points, providing all maneuvers prior to the crash are performed
in the proper sequence. Exceeding the eight minute time period shall result
in a loss of flight pattern points.
7.0 No-Flap Bonus. A bonus of 10 points will be awarded for use
of an aircraft design which does not include operating wing flaps. (When
using Garden State Circle Burner's (GSCB) scoring, this bonus shall be 20
7.1 In the event that OTS Phase II is flown (all applicable
OTS rules except that models shall have operating wing flaps), the 10 (or
20) point No Flap bonus will be waived.
8.0 Spark Ignition Engine Bonus. A bonus of 10 points shall be
awarded for use of an operating spark ignition engine.
8.1 Glow engines converted to ignition may not be used. Ignition
engines must either have been manufactured during the Old Time Stunt era
or be a reproduction engine that has been approved by the Society of Antique
8.2 Diesel engine bonus. A bonus of 5 points shall be awarded
for use of an operating diesel engine
9.0 Maneuvers. Maneuvers and maneuver descriptions from the 1951-1952
AMA rule book shall apply. A minimum of two laps is suggested between each
maneuver to allow judges time to register scores (Not completing two laps
will not result in a loss of pattern points.)
9.1 Takeoff and Level Flight. These are two separate maneuvers.
Correct takeoff consists of model rolling some distance after release, rising
smoothly, and climbing to normal level flight height of 6 to 10 feet, within
one lap. Two level laps follow.
10.0 Scoring of Maneuvers. The PAMPA 1-10 x K-factor, or alternate
GSCB system, will be used. See sample score sheets at the end of this document.
Pre-contest announcements shall state which system is to be used, PAMPA
10.1 Unattempted Maneuvers will receive no score (0).
11.0 Rules Change Procedure. The procedure for changing, amending
or adding rules is similar to those procedures used by AMA. Rules change
procedures and forms are available from the PAMPA Rules Chairperson.
