The photo shows Al Lidberg preparing
his Jet Tube for flight at the SW Regionals, Eloy, in January 2002. It's also
the plane Al’s #1 son used to set an AMA 'Rocket'/Jetex record about 20 years
previously!
Our plan comes from an appearance Jet Tube also made in the National Free Flight Society Journal, August 1976

Paul Del Gatto writes:
"For less than two bits worth of material you can build just about the fastest climbing model
flying machine you've ever seen – and we make no exceptions – in this slick,
dressed-up profile version of a Jetex powered 'X-15'.
"Both of the first two X-15's we made were lost out of sight each on its first flight.
These were no back yard flights either."

Paul Crowley, seen here launching his Rock-It A Go-Go, says:
"Here is a model that combines our
favorite sport of model flying with the
jet age. While we don't have the thrust
of a Saturn rocket here, we do have
enough power in the Jetex 150 engine
to achieve a good consistent flying
model.
"There are, I believe, three directions
you can go with a rocket model. The
handlaunched glider type, which gets
plenty of altitude but suffers in the
glide due to the high wing loading. The
large model with a low wing loading
which suffers from lack of altitude due
to excessive drag. So we come to number three, a medium sized light model
to get the best of the first two. We feel
we have reached this goal with Rock-It A Go-Go."

Described as "a fun project", Jetsport is simple and quick to build,
being entirely constructed from sheet balsa.
This was one of the last Jetex plans published by American Modeler,
in 1965.

Heat Seeker III won first prize in the USAF
World Wide competition for 1966. It uses a
Bilgri multispar airfoil for the wing, coupled with a
flatbottom stabiliser.
It was described as having "no tendencies to
spin out of thermals [with] a very
stable glide." Builders were advised: "Light, warp-free,
straight grain balsa selection is
essential. Avoid all warping in
construction. Use three coats of 60:40
dope. Test glide with empty engine."

The designer writes:
"The Sidewinder is an unusual approach to the high power problem present on Jetex powered
models. [T]he fuselage is off-center, and not the side-mounted Jetex unit. […] After
several years of Jetex flying it became apparent to us that for best results the Jetex unit
should be placed so that it is close to both the center of resistance and center of gravity.
[…]
"This has been proven out as the plane is rock steady under power and runs as if on rails".

Tem Johnson also designed a winning PAA-load model,
but with Sizzlestick he was able to design a pure duration free-flight model,
without the constraints of the PAA-load contest rules.

With its distinctive rearward-curving wing and stabiliser tips, Zip-Dip 150 Mk III gained
contest successes for Charlie Sotich at the US Nationals in three successive years, from
1967 to 1969.
"With a reasonable power run this model will do over two minutes without any help
and using a little care in picking the air it will make maxes without too much effort",
said Charlie.

The
following group of plans comprises models specifically designed for the Jetmaster motor. They are
included here because that motor had thrust equivalent to the Jetex 150.
