|The first model Panther was built soon after the Jetex 100 came on the market. The unit was mounted within the fuselage, completely enclosed except for a ducting arrangement made from cartridge paper and utilising the wing root intakes which were intended to carry air past the unit. Unfortunately, this first Panther proved too heavy to provide the sort of performance we expected and it was evident that the thrust from the 100 was not being used to advantage. By lowering the unit out into the wind into a position which brought the thrust line of the motor coincident with the lower contour line of the fuselage a marked improvement in thrust was obtained. After building a lighter version, with not quite so much dope used in finishing, the Panther flew very well and helped collect information which led to the construction of several smaller Jetex 50 models of jet fighters.
