Introduced in February 1952, the 0.46 cc E.D. Baby was the smallest engine ever produced by the E.D. company. Although sales declined following an initial burst of popularity in 1952-53, the Baby managed to remain part of the E.D. range until early 1962. Somewhere between 15,000 and 20,000 examples ended up being made during that ten-year period, most of them during the first couple of years. Three distinct variants of the engine appeared during the engine's production life.

The Baby was a very smooth runner with a more than adequate performance for powering the small free flight sport models for which it was intended.  It was even able to do a creditable job of flying a small control line trainer, as my late mate Ron Chernich demonstrated way back in his youth! It was perhaps not the easiest of engines to start, but neither was it particularly difficult - it just needed some knowing. 

A detailed article by Ron Chernich with additional input from myself and E.D. guru Kevin Richards may be found elsewhere on this website.  This article includes some present-day bench test data.
