CLASSIC "B" TEAM RACING
REGULATIONS & RULES for AUSTRALIA
for year 2000 onwards.
OBJECTIVE. It is the purpose of team racing to fly semi-scale realistic model aeroplanes in direct competition through a series of heat races and a final. Records only apply to races flown on grass surfaces.
Original model designs that can be documented to have been designed, constructed and actually flown in competition prior to January 1, 1966 are eligible to compete in this event. Any other model can be built, but must conform to all the specifications of the 1965 rules.
1. MODEL SPECIFICATIONS
(a) Engine shall be as listed below. It shall be completely cowled with only glow plug, needle valve stem, cut-off lever, (if fitted) fill-vent tubes, or exhaust permitted to protrude through the cowling. A small access hole for choking is permissible.
Allowable engines: Any engine up to a maximum of .29 cid manufactured for commercial sales prior to January 1, 1961 or any "modern" plain bearing engine up to.29 cid. No tuned pipes are allowed. No metal engine mounting pans are permitted. Propellers must be wood, nylon or commercially available glass composite. All carbon fibre or glassfibre construction not permitted.
(b) Model shall have a cockpit or cabin containing a dummy pilot=B9s head with both being in proportion to the model. The minimum distance from the top of the pilot's head to the bottom of the fuselage shall be 3-3/4" and the minimum fuselage width where the pilot is located shall be 2". The model shall have a minimum effective wing area of 125 square inches.
(c) The model's landing gear shall have two wheels, placed side-by-side with a minimum separation of 4". Minimum wheel diameter is two inches (50 mm sizes are acceptable)with a 1/16th (1.5 mm) negative tolerance. This means the absolute minimum wheel diameter is 48.5 mm.
(d) Fuel used will be the contestant's choice. Any substance banned by the MAAA will not be permitted.
(e) Fuel tank, including filler line and fuel line from tank to needle valve, shall hold no more than 30 cubic centimetres Fuel systems shall be subject to measurement at any time. The tank must be filled through a filler pipe that is not fitted with any sort of valve. The overflow can be either a pipe or a schraeder valve. Engine shutoffs are recommended but are not compulsory. If fitted they must not be used in flight during a race. The penalty for this is 30 seconds added to the race time. Shutoffs may be used during the warm up.
(f) Model shall have the contestants VH number on top of a wing panel.
(g) Strengthening is permitted, including the use of glass fibre for covering. The use of any carbon fibre is not permitted.
(h) Team Racers shall not be acceptable if they are pod-and-boom, flush cockpit, fibreglass or carbon fibre shell, single wheel, or flying wing designs.
2. MODEL SAFETY REQUIREMENTS:
(a) All models must pass a general safety inspection by the Contest Director or his nominated assistant.
(b) Line length, measured from centre line of the model to centre of control handle, must not be less than 60 feet, or longer than 60'.6".
(c) Two line systems are required and each line shall have a minimum diameter of .015". No internal line hook-ups are allowed.
(d) The lines and model control mechanism shall withstand a 20G pull test at the handle.
3. FIELD SAFETY REQUIREMENTS:
The following changes in field layout and racing safety requirements are based on the FAI Sporting Code for F2C Team Racing. Dimensions, figures and methods stated here must always be in agreement with the current FAI Sporting Code in the future.
(a) Pilots must stay near the centre of a 10 foot radius centre circle and walk around the centre while flying.
(b). Pilots must move to the edge of the centre circle to land for refuelling or at the finish of a race. Pilots must keep one foot inside the "centre" circle during the start of the race and during pit stops.
(c) During a race, any pilot not flying (unable to continue or having finished), must take a sitting or kneeling position outside the centre circle and keep out of the way of other pilots. He, or she, may not leave the Racing Zone until the finish of the race.
(d) Pilots should be crouching, straddling the centre circle for the start of the race and for take-off after refuelling during a race and move back to the centre of the circle as quickly as possible when racer becomes airborne.
(e) The "Pitting" or "Flying" circle shall be a radius of 74 feet from the centre of the flying area with eight equally spaced pitting segments. Crew members must keep themselves and their equipment outside the "Pitting" circle during the race.
(f) Crew members shall not step into the Racing Zone with both feet.
(g) Crew members shall not use any device to retrieve a model.
4. ENTRY AND QUALIFICATION.
(a) The individual team shall consist of one pilot and not more than two crew members.
(b) While the entrant need not necessarily be the pilot, he, or she, must be a member of the team.
(c). A team may enter two models.
5. RACES;
(a) Heats will be flown over 70 laps. The final will be over 140 laps and will consist of teams who have flown the 3 fastest heats. One pit stop is complusory in the heats and two in the final.
(b) A two-minute preparation period consisting of a 90 second warmup and a 30 second cool down will apply. Towards the end of the cool down "10 seconds" will be announced with a loud countdown of the last 5 seconds ending with a sharp, clear "GO" signal.
(c) At that moment the crew members must be standing upright close to their model and the pilots must be crouching on the border of the centre circle with the control handle near the ground below the knees.
6. RACING ETIQUETTE
(a) Pilots must keep their controlling hand and the model on a plane perpendicular to a line joining their shoulders and passing through the centre line of their body, pilots must also keep their controlling hand on the vertical line between the middle of the chest and the top of the forehead, except when passing, taking off and landing when an exception of three laps is allowed.
(b) Models must fly at a normal height of between 6 and 10 feet, except for passing, take-off or landing.
(c) Passing must be done by overflying, and the pilot must warn his fellow competitors of his intention to overtake them.
(d) The model is not in any case allowed to fly over 18 feet high when passing a competitor.
(e) The pilot should always find himself on an imaginary line between the centre spot of the circle and the model.
(f) The model is allowed to fly a maximum of two laps without the motor running.
(g) Landings take place inside the pitting circle.
(h) The model must touch the ground with its motor stopped before the mechanic is allowed to catch it.
(i) After the mechanic has caught the model, he must go to the pitting area at (or immediately behind) the point at which the model was stopped. If that pitting area is already occupied, he must go to the next pitting area ahead of his stopping point. A pitting area is occupied if a mechanic is standing at such an area, even if his teams model is still in the air.
(j) Should the model stop between two pitting areas, the mechanic must go to the nearest free pitting area.
(k) After the mechanic has caught the model, but only then, the pilot is allowed to put one foot outside the centre circle.
(l) During the refuelling and the restart of the motor, and until the time when he releases the model, the mechanic must keep the model in contact with the ground by at least one point and with the centre line outside the pitting circle. During that time the pilot must be crouching. He keeps his handle and his lines near the ground below the knees until the model starts again.
(m) The model completing the race in the shortest time shall be declared the first place winner with others following in order of race completion times. After all models have completed the race, pilots should land and clear the area for the next race.
(n) Any conduct or flight manoeuvre by a pilot that endangers, or results in damage to any other participating pilot or his model will constitute a foul and cause immediate disqualification from the race in which it occurs. Pilots will be warned for whipping, walking the back of the circle, pivoting or blocking. A team will be allowed two warnings during a race. A third warning will mean disqualification. As with Vintage A team race, interpretations of the Classic B rules should be relaxed with only blatant offences resulting in disqualification.

SUPPLEMENT TO 2000 "B" T/R RULES
Due to the fact that old racing engines are not readily available, are
expensive and those who have or can get them donšt always want to use them
in competition, a modern engine group has been included with the old engines
as allowable power.
