The FROG 50 was described in Peter Chinns Accent on Power column in the April 1952 issue of Model Aircraft subsequently being featured in published engine tests by (presumably) Chinn (Model Aircraft) and Ron Warring (Aeromodeller) both of which appeared in the respective magazines August 1952 issues. The two testers found broadly comparable levels of performance - Chinn obtained 0.042 BHP 12600 RPM while Warring achieved a somewhat lower figure of just over 0.030 BHP 12700 RPM.

From a comparative standpoint these figures are consistent with other tests by the two individuals - Chinn generally tended to find more power than Warring for the same engine and commonly also found that power at higher peak RPM although not in this instance. Presumably this was down to differences in the respective engine management and testing techniques. Both reviews were generally favorable although the fiddly little compression screw transverse needle alignment challenging starting qualities and general finicky-ness of the engine came in for some criticism from both reviewers.
