Jets
One of the most common images most people probably envision when
they think of radio controlled planes is the single engine propeller-driven
airplane. But it has always been the nature of this 'community'
of builders and pilots to model every type of aircraft imaginable.
This trend inevitably continued into the large genre of jet-powered
craft.
The challenge has always been to deliver the
rearward thrust required to drive the plane and ultimately to
do it in a way that most closely mirrors the look and performance
of the full-scale counterpart.
There are now several ways of acheiving this.
The rush of technology and manufacturing to meet the requirements
of model jets has led to the availability of a variety of small
jet turbine engines that operate just like the big ones do. For
the serious jet enthusiast turbine power is the ultimate because
it delivers the look the sound and performance we have come to
expect from jet aircraft.
The availability of a growing variety of high
powered, high rpm electric motors has led to a new breed of electric
ducted-fan jets. Typically these are smaller than their turbine
powered brothers but the upper end of the electric jet range is
a close second in performance. In addition, electric power makes
possible the tiny 'park fliers' and 'foamies' that can be flown
in smaller spaces.
Another option is the i.c powered ducted fan.
This used to be the primary way to propel a scale jet before the
turbines became practical enough to find widespread use. Typically
these are powered by very high performance nitro 2 stroke engines
that run at very high rpm in order to deliver the thrust needed.
