у американцев есть целый класс, вернее подкласс горных планеров RC Slope Soaring Combat.Сообщение от Sergey_S' post='15795' date='21.1.2008, 17:10
Я бы еще ограничил мах. нагрузку на крыло. Хотя перерыл на Rcgroup кучу тем но нигде не нашел ссылок на какие-либо ограничения.
Требования к модели следующие:
14.3.5. Aircraft Specifications
14.3.5.1. With the exception of control
surfaces, covering and structural reinforcements
listed below, the aircraft must be constructed
entirely of expanded bead, plastic foam material.
14.3.5.2. The maximum allowable
wing span shall be 49 inches.
14.3.5.3. The maximum allowable
flying weight shall be 35 ounces.
14.3.5.4. Wings shall have a plastic
foam leading edge at least 1 1/2 inches wide,
measured chordwise, the entire span of the wing.
The wing may be covered with film covering
material, vinyl tape, fiber reinforced vinyl tape or
any combination of the three. Wood, metal, solid
plastic, carbon fiber, Kevlar or any resin
impregnated fiber material on or in the
wing leading edges are not permitted.
14.3.5.5. Wing spars of any non-
metallic material are permitted, provided they do
not violate the provisions of Section 5.4 (more
than 1 1/2 inches away from leading edge at any
point along the span). Maximum total cross
sectional area for spars shall not exceed 1/2 sq. in.
Moveable control surfaces at the wing trailing
edge (ailerons) will not be considered a part of
the total spar cross section.
14.3.5.6. The fuselage of a Class B,
Conventional Aircraft must have a plastic foam
nose section at least 1 1/2 inches in length. The
fuselage may have longerons of any non-metallic
material provided their total cross-sectional area
does not exceed 1/2 sq. in. area, and that the
longerons do not extend into the forward 1 1/2
inches of the nose. The fuselage may be covered
with film covering material, vinyl tape, fiber
reinforced vinyl tape or any combination
of the three.
14.3.5.7. Any flight control surfaces
may be constructed of wood or corrugated
plastic/paper material. Metal, solid plastic,
carbon fiber, Kevlar or any resin impregnated
fiber construction or covering
material on the control surfaces is not permitted.
14.3.5.8. Any ballast added to an
aircraft must be imbedded and secured internally
within the aircraft structure and may not be
attached externally to the aircraft structure.
14.3.5.9. No plane shall use any form of
thrust power. Engines, electric motors,
compressed gas or chemical propellants are
prohibited. Aircraft converted from electric
power must have the motor, motor battery,
propeller and any hard surface hatches
removed from the aircraft prior to competition.
14.3.5.10. There shall be no limitation
on the number of controls. The builder-of-the-
model rule does not apply for this event.
14.3.6. Competition Classes. The Contest Director
may select from the following classes.
14.3.6.1. Class A, Flying Wings. Open
to any aircraft, which does not have a horizontal
stabilizer surface separate from the wing
planform (i.e. "tail-less" aircraft).
14.3.6.2. Class B, Conventional
Aircraft:
Open to any aircraft which uses conventional tail
control surfaces, separate from the wing and
attached by a fuselage structure.
14.3.6.3. Class C, Unlimited. Open to
any aircraft complying with the requirements of
Section 5 (i.e. combined flying of class A and B
aircraft).
ИМХО, есть смысл сразу ориентироваться на открытый класс.
Давай мэйл, я сброшу полный текст, там ещё много по организации соревнований.
