Q-97: I have a few questions concerning '3-D' type model aircraft.
Like what is the difference between a '3-D' airplane and a fun-fly type? Where
can I get plans or kits for '3-D' type airplanes? Where can I find a description
of '3-D' type maneuvers?
A-97: Using the term “3-D” to describe a type of model aircraft began
a few years ago when a new style of maneuvering was developed. “3-D” airplanes
are capable of hovering and doing Torque Rolls, Harriers, Rollers, etc.
These models must have a power-to-weight ratio of at least 2:1 and extremely
quick throttle response to be able to correct for minor deviations while
hovering or flying behind the power curve. The term “3-D” implies glow or gas
power, and the term “E-3-D” describes the equivalent aircraft using electric
power.
Several publications are now covering “3-D” and “E-3-D.” Quiet Flyer
magazine publisher Wil Byers has introduced a new magazine called 3-D Flyer,
which specializes in all aspects of this type of aircraft. You can find an
advertisement and special offer for this publication in the MA Special
Issue 2004 on page 158.
Popular modeling author Dave Baron writes the new monthly “Freestyle” column for
Fly RC magazine. He has written some of the best articles about the
physics and dynamics of flying behind the power curve.
These references should at least provide you with a start!
