Jetex rocket motors were a big deal
to my friends and me in the early 1970s, although they had been around a lot longer
than that. In fact, this article in the March 1957 edition of American Modeler
magazine was
printed a year before I was born. The motors did not product a whole lot of thrust,
so light weight was an absolute necessity. Once I finally got the buggers lit, they
worked well and made a really cool hissing noise as the fuel burned. However, the
amount of fuse wire provided never was enough to use up all the pellets in the pack
because the darn things kept going out as it tried to enter the nozzle. No doubt
it was my ineptness that caused the problem, but my excuse was only being a dumb
kid. Now, I have a whole lot of fuel pellets but no engines for them. If you are
a Jetex man, please check my
Jetex fuel pellets page.
Jetex-Powered "VTO" is Third in Series of Air Adventurers Models
 Model #3 in the easy-to-build, great-fun-to-fly
series of Air Adventurers Club model aircraft designs is this unusual "X-tail" jet
fighter-like craft. Officially, it is designated Series A, Mach 3. For power it
uses a real jet engine, the Jetex "35" or "50" or an equivalent solid fuel propulsion
plant. Tail fins which give the plane a rakish appearance are very easy to make
and mount. All you do is cut out 4 rudder-fins. Cement two together at right angles,
do same with remaining two - let the cement dry completely. Then each "V" is cemented
to the fuselage rear to form an "X." Note that modeling clay is called for to balance
the model for a smooth, even glide. Use coupon below (or copy) to join AAC.

Notice:
The AMA Plans Service offers a
full-size version of many of the plans show here at a very reasonable cost. They
will scale the plans any size for you. It is always best to buy printed plans because
my scanner versions often have distortions that can cause parts to fit poorly. Purchasing
plans also help to support the operation of the
Academy of Model Aeronautics - the #1
advocate for model aviation throughout the world. If the AMA no longer has this
plan on file, I will be glad to send you my higher resolution version.
