Description of Event

The AT-6 Racing Class event is intended to provide the sportsman R/C pilot an opportunity to experience the excitement of full scale air racing using a simple-to-build and easy-to-fly scale like model of the AT-6 aircraft. Racing rules for this class are the same as those for the Mini-Reno warbird racing rules, except that AT-6 Racing has specific rules identified below to be used in lieu of any conflicting rules established for Mini-Reno warbird racing. This provides the sportsman AT-6 class competitor with an easy transition should he/she decide to compete in the more challenging SWRA racing formats. The AT-6 class is intended to provide an "entry level" event. The rules for this event are designed to keep the complexity and expense of the aircraft at a reasonable level, and insure that the racing speeds of the entrants are matched closely enough to provide a competitive racing environment. Aircraft are limited to Top Flite Gold Edition AT-6 kits with a stock Supertigre .75 2-cycle motor equipped with the Top Flite in-cowl header & muffler for the AT-6.

Static Judging

Following registration, the first portion of the event will be static judging. Aircraft will be judged for accuracy of outline, color and markings, and craftsmanship using the SWRA scale rules and judge’s guide except for differences contained in this document. There will be no builder of the model rule applied to this event. Contestants will be allowed to enter a second aircraft, to be flown only if the pilot deems the primary aircraft no longer airworthy. If a substitution of aircraft occurs, the contestant must use the lower of the two static scores.
 
 
 
 

The static score accounts for 50% of the final score. An airplane must have flown in

at least one heat to be considered eligible for the best static score award (if one is given). Aircraft displayed for the People’s Choice Award must be the currently flown entry.

Documentation and Scoring

A total static score of 100 points is available to be awarded, comprised of the following scores for the categories listed below:

(1) Accuracy of Outline 40 points

(2) Color & Markings 20 points

(3) Craftsmanship 40 points

To be eligible for the full 40 accuracy of outline points, the contestant must provide a three-view drawing of the modeled AT-6, SNJ, or Harvard aircraft for the outline judge to review the model against. To be eligible for color and markings points, a photo of the real aircraft modeled must be presented to the color and markings judge. The pilot will receive the full 20 points if the photo is provided, and zero (0) points if it is not. Craftsmanship will be scored in the normal manner, based on the SWRA scale rules and judge’s guide.

Aircraft Requirements and Specs

After the aircraft is judged for fidelity to scale, it may be inspected to insure that it meets the requirements and specifications of this event. Aircraft must be constructed from a Top Flite Gold Edition AT-6 kit without modification of any kind to the kit specifications, and must be built according to the kit plans. The model may be any variant of the AT-6, SNJ, or Harvard family of aircraft. Aircraft must be equipped with the requisite stock power plant and exhaust system specified as follows:

Airframe: Top Flite AT-6 Gold Edition Kit.

Wing and tail surfaces built with

kit specified span, chord, airfoil,

and thickness.

Fuselage built to kit specified

diameter and length.

Motor: Supertigre .75 two-cycle engine.

Engine exhaust and intake timing

per factory specs.

Carburetor throat diameter per

factory specs.

Exhaust: Top Flite header (TOPQ7925)

Top Flite muffler (TOPQ7915)

Exhaust system components may

not be modified.

Landing

Gear: Fixed or optionally retractable

landing gear are required.
 
 

Weight: Aircraft must weigh at least 7.5

pounds dry (without fuel)

Safety Considerations & Requirements

All aircraft will be inspected in accordance with the safety guidelines specified in the SWRA Mini-Reno warbird racing rules of this handbook. All contestants must certify that the aircraft entered has been successfully flown prior to entry in the event. The Contest Director may require any pilot to demonstrate safe flight characteristics of any aircraft entered before it is allowed to race.

Race Operations

Once static judging and inspections have been completed, racing will begin. The racing will consist of as many rounds of racing as time allows. If it is possible to race six (6) completed rounds, the lowest scoring round for each contestant will be discarded prior to calculating the final score. The distribution of flyers in each heat will be determined randomly, except as required to eliminate frequency conflicts. Each heat will consist of at least four (4) aircraft, if possible. All aircraft will be flown with the fuel and propeller provided by the Contest Director. Each entered aircraft may only be flown by one pilot. Multiple pilots sharing the same aircraft will not be allowed. The Contest Director retains the right to refuse event entry to any aircraft that does not, in his/her opinion, meet the intent of this event. Course description, pilot requirements, and other race operational procedures will be as set forth in the Mini-Reno warbird racing rules.
