1950s Frog 150 1.5cc Engine For Model Aircraft This is a used, vintage, 1950s Frog 150 1.5cc Engine For Model Aircraft. Is this the short-lived "Red Glow” glow-plug version or the compression-ignition (diesel) engine: I have no idea! In fairly good cosmetic condition, with some rust and blemishes on the casing. It hasn't been cleaned or tested and there may be some missing parts. Unfortunately, as you have probably realised, I don't know anything about model engines so please use the appended images as a guide to condition. Made by International Model Aircraft Limited (IMA), Merton, London, UK. Their brand name was FROG, an abbreviation for Flies Right Off Ground.
