- 2014-01-02 00:56 May any type of thread that is conventionally used in sewing garments be used to attach the functional components of the glider to each other, namely, cotton thread, polyester thread, elastic thread and silk thread?
Yes, any type of thread may be used to attache the functional components.
- 2014-01-02 03:06 Is ballast that is not permanently attached to the glider allowed in order to bring an individual glider up to the 3.0g minimum weight?
Yes. If ballast falls off during the flight, timing will stop when the ballast touches the ground. Ballast does not need to be permanently attached. If the event supervisor feels ballast changes, repairs, or other modifications have potentially made the glider over or underweight, the glider should be reconfirmed prior to any remaining flights.
- 2014-01-02 01:14 How will the wing-span be measured?
Wing span is the projected span, wings level, projected on a horizontal plane, tip to tip. It is usually measured with a simple gage and has to pass through a 28.0 cm gap (parallel edges) without touching. Think of the gage as physically representing two parallel lines spaced 28 cm apart. Glider must pass when the tips are oriented to a plane orthogonal to both lines.
- 2014-01-02 01:11 May the gliders have a propeller on the nose of the fuselage?
Yes, A glider may have a propeller as long as there is no power source for the propeller, provided it is made from the allowed materials (3.c.), and meets the blunt nose requirement (3.f.) Also, remember elastic is only permitted as part of the launch handle and is not permitted on the glider.
- 2014-01-02 01:23 Can you specify what do you mean by launch handle?
A launch handle is an object attached to the elastic used to propel the glider as long as it follows the parameters defined in the rules. Examples are, but not limited to: a small stick, pencil, pen, dowel, or something more complex.
- 2014-01-02 01:30 Rule 4.b. states, “Once competitors enter the cordoned-off competition area to trim, practice, or compete they must ....not receive outside assistance, materials, or communication.” Does this apply to open practice the day of competition?
Yes, this rule applies to Open Practice the day of competition. The rule is specific including trimming, practicing and competing. Coaches & students are not allowed to interact in the cordoned off practice area the day of the competition.
- 2014-01-02 01:31 Can a launch handle/device be a freestanding structure in contact with the floor?
Yes provided it is safe and meets the size and construction requirements (3g.) and is operated by a single competitor at floor level (4g.)
- 2014-01-02 01:34 Can you clarify what "floor level" means?
The student must be in direct contact with the floor and not on another raised suface (chair, ladder, bleachers, balcony, etc). There is mo requirement as to posture: standing, kneeling, sitting, prone at chose of the competitor.
- 2014-03-09 18:56 Is your hand holding the elastic allowable as a launch handle?
Yes, your hand holding the elastic may be the launch handle.
- 2014-01-02 01:38 What are the exact specifications needed for a glider to be considered a Canard Configuration?
There are two horizontal aerodynamic surfaces in elastic launch gliders. The larger surface is the primary source of lift and is considered the "wing." The smaller is a stabilization source and is considered the "horizontal stabilizer." Canard configurations place the horizontal stabilizer in front of the wing (reverse that of traditional layouts.) No aerodynamic surfaces may be behind the main wing.
- 2014-01-02 01:56 Does a "canard configuration" refer only to the horizontal surface, i.e. can there be a vertical fin at the rear of the glider?
Yes, a vertical fin may be at the rear of the glider for a canard as long as it does not provide any lift.
