Update to Old-Time Stunt rules

Guess what, the OTS rules have to be updated AGAIN! Some rules that were voted in some time ago have just resurfaced and have been added in. SOOOOOO..

Here are the OTS rules in full. I think this is it ­ all of it. They will be posted and sent everywhere. Let others know that the website will contain these rules, the ones right below

The newest addition, which is really an old addition, is all under the Undercarriage section.

PAMPA Rules For Old Time Stunt

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

3.1.1 Undercarriage. 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. 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 handling. Undercarriage addition. A landing gear may be added to those model designs that originally had a drop-off gear or had no fixed takeoff/landing gear. Model designs with drop-off gear. Where drop-off gear was a feature of the original model design, contestants should preserve the appearance and location of the original gear, but must disable its drop-off function for competition. Drop-off landing gear will not be permitted. Model designs with no take-off/landing gear. If the original model design did not have a takeoff/landing gear, the design of the added takeoff/landing gear must be consistent with the prevailing takeoff/landing gear used on similarly configured model designs of the era. [Note: This requires that a normally configured model (straight wing, tractor engine and aft horizontal tail) will have its takeoff/landing gear mounted to the fuselage with two appropriately- sized wheels separated from each other by an appropriate distance with their axels at least one diameter of the wheel in front of the wing's leading edge, such that the aircraft has a noticeably nose-high attitude while at rest on the ground. A takeoff/landing gear added to an unorthodox configured model should be consistent with the takeoff/landing gear design on a similarly configured full size or model aircraft of that era as documented by the contestant. A contest director may disqualify a model that does not comply with the intent of these guidelines.]

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 points.

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 Modelers (SAM).

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 or GSCB.

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.
