Paul Del Gatto had a fondness for high-speed, high-altitude craft with a spacecraft
or missile-like configuration. The power of the
Scorpion 600 allowed him to fly faster and higher than ever before.
In this model, he offered the option of a cut-down augmenter tube to boost the power
even further. To aid retrieval, he added a fuse-operated parachute recovery mechanism.

John O’Donnell, a contest-winning UK modeller, told Frank Zaic that
Castaway was the “latest in quite a long line of Jetex powered models of assorted sizes, shapes and weight, produced by Hugh and I over the last few
years. Obtaining ratios of five or six was quite easy, but any more was a different tale. Due to the limited power and heavy weight of the
Jetex unit, a reasonable power/weight ratio of the complete model
necessitated ultra light model structure. Eventually the high thrust line
layout was adopted and thus enabled looping to be controlled without
resorting to knife edge trimming methods. The Castaway has a
76.5% C.G. which gives reasonable stall behaviour, and the very high
location of the Jetex discourages loops. Flight pattern should be a
very steep spiral with rudder to provide turns and wing warps to give
roll. Duration of about 1:30 to 1:40 off a single charge (7.5 sec. effective) can be obtained in evening conditions without apparent lift”.
To achieve a firmer mount for the motor than that
supplied in the Scorpion kit, John used a thicker wall aluminium tube
which was pushed into the socket at the back of the motor. This is the same procedure that
Bill Henderson adopted with this motor.
The Scorpion's power was used to enable Castaway to achieve R.O.G. flight.
