IMPORTANT NOTICE FOR ALL NORWIND FLIERS
When booking the hall for the meetings, we are required to provide evidence of public liability insurance.
After considering the options and taking advice, the easiest (and cheapest way) is to run the meetings under the auspices of the Bolton Club, which is BMFA affiliated. Tom Crompton and Dave Whitehouse are both officers of the Bolton Club, which makes the affiliation legal.
Up to this point in time, Clayton (and now NORWIND) have remained independent identities in order to preserve their distinct characteristics.    We want to make it clear that we wish NORWIND to continue in its present informal form, without making unnecessary rules and changes, so in terms of flying, life will go on just as before and this is the cheapest way that we can think of to obtain the required insurance cover.  We will,  have to require fliers to show proof of BMFA membership. and current BMFA membership cards will need to be produced for each meeting if you wish to fly. We are allowed to have a FEW guest fliers per season, but regular fliers MUST be BMFA members at the first meeting in September.

There are two ways of doing this: If you have your own individual membership, you will need to provide proof of current membership in September and then again in January (as BMFA membership runs from January to January). If you are not already a BMFA member, Tom Crompton can arrange it as part of the Bolton Club group affiliation at the beginning of the season. 
We try hard to keep the rules to the minimum, as we want the meetings to be about fun. We hope that you will continue to support NORWIND, which has a long history of friendly flying.
Dave Whitehouse, Tom Crompton & Tom Tomlinson (first name alphabetical order!).
NORWIND COMPETITION RULES (Page 1)
AND IMPORTANT NOTICES
PLEASE READ CAREFULLY
NORWIND RULES FOR USUAL COMPETITION CLASSES
(Some adapted to suit the hall and time limitations and to encourage participation)
Limited Penny Plane (AMA rules using restricted motor to suit NORWIND hall)
The model shall weigh at least (3.10 grams) without the rubber motor.
The overall length, including the propeller, shall not exceed 20 inches . The length is to be measured by placing the prop blade leading edges against a vertical plane. The rearmost part of the model must not extend beyond a line parallel to the
vertical plane and 20 inches from it.
The projected wingspan, measured perpendicular to the motor stick, shall not exceed 18 inches.
The distance from the front of the thrust bearing to the rear motor hook shall not exceed 10 inches.
A single direct drive (ungeared) rubber motor and propeller shall be used to power the model.
The rubber motor shall not be enclosed.
NORWIND modification: The rubber motor shall not exceed 0.75g with motor ring. 0.01g excess shall be allowed for lubricant.
The model must carry a ballast stick weighing a minimum of 0.75g, which should be approximately half of the distance between the motor hooks

The wing chord shall not exceed 5 inches. The dimensions of the horizontal stabilizer shall not exceed four 4 inches chord by 12 inches span.
The motor stick shall be solid and made from a single piece of wood. (The tail boom may be a separate solid piece.)
The propeller diameter shall not exceed 12 inches.
No gadgets of any kind are permitted on the model (i.e., variable pitch props, automatic incidence changing mechanisms, etc.).  Limited Pennyplane is limited to monoplane models.

Legal Eagle (Models must R.O.G. from floor)
DRAWING REQUIREMENTS
1. Drawing must fit on one side of one sheet of legal size (8-1/2" x 14") paper.
2. No component parts drawing may be superimposed or overlap another and
must clear one another and the edge of the paper by at least 1/8 inch.
3. Wing(s) and stabilizer must be drawn full span, tip to tip and fuselage drawn  in its full length from nose through tail in one piece.
4. Fin(s) may be drawn where space allows and not necessarily attached to the  side view.
5. Landing gear must be drawn in its place on the side view showing its full  length.
6. No top or front view is required.
7. Drawing must be presented to C.D. on demand.

DESIGN REQUIREMENTS
1. Smallest wood size to be 1/16 inch square except for propeller.
2. Fuselage measured to its outside surface must contain a space 1" x 1.5" x 3".
3. Fuselage must have a cabin or open cockpit with a raised windshield of at  least 30 degrees of clear or translucent material. Cockpit must be actually  open, with a headrest or canopy.
4. Flight surfaces; Leading and trailing edges cannot parallel each other.
5. Tip outlines must have no straight lines except for stabilizer where a twin fin  is used.
6. If twin fins, or two wings are used in the design, parts may be built in  duplicate over the same drawing.
7. Jap tissue required on all non-sheeted, open framework surfaces except for  fuselage surfaces covered by a flying surface directly attached to the  fuselage and areas involved in an open cockpit or minimum access area to  the motor. No ultra light film covering to be used, unless used for windshield  or windows. Flight surfaces may be single or double covered.
8. Landing gear must use at least one 1 inch diameter wood wheel.
9. Use of motor stick(s) or tube(s) O.K. and if used, must be shown on the side  view in one continuous length in the proper position.

14g Bostonian
Maximum projected wingspan shall not exceed 16 inches.
Maximum wing chord (measured parallel to the direction of flight) shall not exceed 3 inches.
The propeller(s) must unmodified, commercially available plastic type and shall not exceed 6 inches in diameter.
The length of the model excluding the propeller(s), but including the thrust bearing(s), shall not exceed 14 inches. This measurement will be made in the direction of flight and will include surfaces, which extend beyond the thrust bearing or fuselage end because of a sweep or unusual mounting.
The fuselage structure must include a box, which has minimum dimensions of 1.5 inches x 2.5 inches x 3.0 inches. The width (the horizontal dimension perpendicular to the line of flight) of the fuselage shall not exceed three inches. The box must be enclosed within the fuselage structure and must be covered so as to restrict free air movement through the box. Normal sag of the framework between supports caused by the tension of the covering will not be considered as a violation of this rule.
The fuselage structure must be built-up so that the longitudinal members (the longerons) support the forces produced by the rubber motor. A solid or hollow motor stick with a lightweight structure added on is not acceptable.
The fuselage must have a transparent windshield and side windows of at least 1 square inch each. An open cockpit design need not have side windows. But the windshield must meet the 1 square inch rule  and must stand at least 3/4 inch  above the top of the fuselage.
The model must have at least 2 wheels of at least 3/4 inch diameter, each on a separate leg, which rotate freely and support the model for takeoff and landing.
All flying surfaces must be covered on both sides or must be solid material with a thickness of at least 1/16 inch at the maximum point in each chord wise element.
The total projected area of the secondary horizontal surface(s), excluding that inside the fuselage, shall not exceed 24 square inches. This may be a conventional stabilizer and/or a canard surface.
The airframe, excluding the rubber motor(s), shall weigh at least 14 grams (Adapted for NORWIND).

Precision/Duration
This shall be a "one model" competition, the model to be designated in advance by the Contest Director.
The Competition has 2 separate parts: Precision & Duration. Each is treated as a competition in its own right.
PRECISION: The CD will nominate a target time on the day.
Each competitor will be allowed 3 flights, each to be timed by TWO DESIGNATED timekeepers and the times averaged and agreed. The time will be measured from release of the model to the time when the first part of the model touches the floor. In this way both ROG and hand launch are permissible. Times will be measured to a tenth of a second Times must NOT be rounded up or down as split seconds can determine places. Any flight which exceed the target will be deemed as void. In the event of a tie, second (valid) times to count.
DURATION: Any number of flights, any BMFA member to time, 10 seconds bonus for ROG. Second flights to determine places in event of a tie.
After consulting the membership, it was decided that any commercially available unmodified prop may be substituted for the carved prop shown on the plan.
