WREN ENGINES
As I am a director of 'Wren Turbines ltd, all of my models use Wren engines with the
exception of the first Jet 1, which used my home-built 'Schreckling' engine.

JET ONE
Designed by Terry Lee
The first jet I ever made was for my home made 'Schreckling' engine.
When we made the first Wren 54 engine, this was thought to be the ideal model.
As it is very easy to fly, it became the standard jet trainer for the local
'jet jockeys'. This particular model is number 7, & consists of a glass fibre
fuselage (the original was plywood) foam wings & balsa tail feathers. Because
it can fly slowly, while still capable of aerobatics, it is suited to flying off
small club fields.
Engine is a Wren 54 Mk 3
Thrust is 14 pounds
Wingspan 65"
Weight 11 pounds.

of its similarity to a King Kat & a Bob Kat only smaller.

BUTTERFLY
Designed by Terry Lee
Named 'Butterfly' because of its 'V' tail - also known as a butterfly tail.

quickly - one week, it is of simple lite ply sheet fuselage, foam wing (paper
covered) & balsa sheet tail.

simplest form. Engines are both hand started & fed from one 1.5 litre fuel tank. If flown
gently (scale like) a flight time of 10 minutes is easily attainable.
