“True FROG buff wants to make the model look like FROG model,

not like its real prototype.

And, if FROG model has some visual differences,

he is always sure that it only makes it look nicer…”

“M-Hobby” magazine


FROG input into development of scale modelling in Soviet and post-Soviet area is hard to overestimate. But, before start talking about late period of life of FROG press molds, it’s worth to run a brief excursion into a history of this trade mark.

FROG abbreviation stands for Flight Right Over the Ground. The name was invented in 1932 by managers of International Model Aircraft Ltd. (IMA) and originally used for flying models. However, when in 1938 Penguin series was presented (comprising aircraft detail sets made of cellulose acetate), FROG began to be more and more associated with scale models, including wooden ones.

The real breakthrough took place in 1956-1959, when more than 20 models made of plastics were released under FROG trademark. Some of these models appeared to be so fortunate that they are, in fact, still in production! Over the next five years FROG saw no abrupt failures, but in 1965 IMA was merged with Rovex Scale Models Ltd and ceased to exist in 1972. During that period, British economics came into continuous recession and not all model manufacturers managed to grow out of it.

Dynamics of change of names of FROG trademark holders in 1955-1977 is presented below:


1955-1965 – International Model Aircraft Ltd.

1966-1967 – Rovex Scale Models Ltd.

1967-1969 – Rovex Industries Ltd.

1970-1971 – Rovex Tri-ang Ltd.

1972-1973 – Rovex Ltd.

1974-1977 – Rovex Models and Hobbies Ltd.




If you examine it in more detail, FROG models can be divided into five generations, which partially overlapped each other.
1st generation (1955-1958)

Famous “airman’s head”

U/C wheels, legs and doors molded as a single detail

Heavy raised panel lines and rivets

Absence of wheel wells


2nd generation (1956-1962)

Heavy recessed panel lines

Empty cockpits – no pilot, no seat

Marking elements engraved in plastic


3rd generation (1963-1967)

Movable U/C details: rotable wheels, retractable legs

Movable control surfaces: rudders, elevators, ailerons

Thin raised panel lines

Aircraft cockpit details: floor, seat, pilot figure

Separate engine details.


4th generation (1968-1974)

Placement of details within a frame

Model stand in one of the frames, together with other kit details.

Thin hexagonal frames


5th generation (1974-1977)

Circular frames

Absence of the stand (or Skybase stand)

New pilot figures


Following their sale to Novoexport in 1975-1977, FROG models literally found a new life, as they became hugely popular in Soviet Union – even more popular than VEB Plasticart kits produced in DDR.
