- In regards to Radio Control Models, these terms generally
refer to specific size categories.
Originally, these names were born from early miniature radio
control helicopter internet group discussions and treads on
related subjects by MIA Micro-FLIGHT, via various internet user groups
such as RC Groups and Yahoo Groups (Previously known as Yahoo Clubs)
to name a couple,
but also MIA carried on, in the market, with actual products, in these respective
To our knowledge, besides MIA Micro-FLIGHT, no one else in the world has had an extensive
history and original content in regards to these specific areas,
since the very early years of their conception, development and market
exposure, which started around 1998. It is for this
reason, that we have also established, the MIA Museum, to share
with the public, the countless material and amount of work that
MIA Micro-FLIGHT has accumulated in these, Micro, Sub-Micro,
Palm-Size™ areas over the
span of many years, and since the very first MIA micro
size helicopter product, the Shark Rubber Powered Helicopter, a
12 inch rotor diameter, 1 ounce, free-flight model sold in the
In recent years, other companies have adopted these terms, and
are now standard titles to describe similar products in the
miniature RC Model Hobby industry.
Pitch Adjustable Rotor Head, a term
formulated by MIA Micro-FLIGHT to define a type of rotor head
with dual integral, blade angle of attack, adjusting mechanism.
This type of rotor head, resembling a sort of turnbuckle, was
developed, as an upgrade part, and utilized in the MIA Robin
280, as means of providing fine tuning of the helicopter flight
dynamics by allowing the user to manually adjust the angle of
each blade independently.
- A MIA
Micro-FLIGHT Trademarked term derived from the word "tough" to
describe the durability of MIA products, bearing such name.
G10 - A type of lightweight and highly durable material
composed of glass fibers and resin, typically fabricated into
thin sheets, from which parts, such as MIA helicopter
main frames, rotor heads and other parts, requiring durability
and some flexibility, are made from.
- A flybar design formulated by MIA
Micro-FLIGHT, to do away with the typical flybar rod, separate
paddles and tip weights, that is part of almost every Radio
Control Helicopter. This type of flybar, also eliminates the
need to fiddle with the center point location of the bar and
subsequent balancing adjustments, making it easier to install.
Manufacturing of such, combines all three parts, the rod, and
both paddles as a single unit. Made from G10 and incorporating
multiple perforations on each paddle leading edges, so that tip weights,
can be added, by means of screws/nuts, as required, to provide
fine tuning of the helicopter model's gyroscopic stability.
BARLESS - A name formulated by MIA Micro-FLIGHT to describe A helicopter without
the typical flybar. The more commonly utilized name, in the RC
Helicopter Hobby Industry, is "Flybarless".
Heli - Helicopter
RTF - Ready To FLY
ARTF - Almost Ready To Fly
RC - Radio Frequency Controlled
IR - Infra Red Wave Controlled
Swashplate - A helicopter's steering mechanism, in the
form of a complex multi-axial pivoting double plate.
Flybar - A bar typically mounted above or below the
helicopter's rotor head, equipped with end paddles and tip
weights to provide control and gyroscopic stabilization.
Fixed-Pitch - A pre-defined set positive angle of attack
in a helicopter rotor blade, which provides thrust and allows a
helicopter to lift itself, via an increase in rotor speed.
Collective-Pitch - A variable angle of a helicopter rotor
blade, which provides positive or negative thrust and allows the helicopter to lift itself
upright or inverted, respectively by a
combination of rotor speed and positive or negative angle of
attack. This allows for a more efficient, power usage, ideal for
advanced and aerobatic maneuvers.
LG - Landing Gear
FFF - Fast Forward Flight, as the name implies. Also referred to
Fan-Fold-Foam, a type of insulation foam, sold in folded sheet
form, and widely used by people who scratch build foam models,
called "foamies", from it.
Li-Pol - Lithium Polymer, a chemical formulation, fairly
recent battery cell technology, which yields high energy
capacity, at a very low weight. Requires thoughtful and extra
Ni-Cad - Nickel Cadmium, a chemical formulation, as applied to older battery
technology, which yields a heavy battery, but less complex and more user
friendly than Li-Pols.
NMH - Nickel Metal Hydride, a chemical formulation, that
followed Ni-Cad battery cell
technology, slightly lighter in weight and better than NiCad, but
still not as efficient and as light weight as Li-Pols.
Cambered Blade - An aircraft's rotor or propeller blade
that has a specific curvature to provide thrust.
Flat-Bottom - An aircraft's wing or rotor blade airfoil,
that, as the name implies, has a flat bottom.
Symmetrical - In reference to aircraft, a wing, rotor
blade, or airfoil that has symmetry, top and bottom airfoil
shapes are the same. Ideal for aerobatic models.
