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
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 and need fuel, please check my
Jetex fuel pellets
The prices are much better than buying it on eBay.
Jetex-Powered "VTO" is Third in Series of Air Adventurers Models
#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.

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.
