Thanks Scott..I think this will work.
The piston size is close to an .020 or even .010.
Does anyone know what it is?
Thanks

I was just speaking Bob Langelious this morning about getting a glow plug and plug gasket for my K&B Infant.

Bob is a member of the Brooklyn Skyscrapers Club.

Bob has done several runs of replica K&B 020's and currently has glow plugs available for them.

Control line use?...pretty tiny stuff...maybe Designman would have an idea.

It has been explained to me the engine was meant to be a sport conversion for rubber powered free-flight models...it was suggested the aluminum prop that came with it is deliberately inefficient to avoid over-powering a light "stick and tissue" free flight model.

Anyone else got some info on this little engine?

There are a lot of Free Flight kits designed around the 020 Infant.I think that is its total purpose.I would not use one of the original prop,they seem a little scary to me.Dennis

I believe Hal DeBolt designed the 'Infant Wagon' (a small 1/2A sized stunter) for this engine.

Hal Debolt's "Infant Wagon" was designed for this motor and became VERY popular in the early '50s- it is a micro sized version of his big Stuntwagon. This was the FIRST ever 1/4A motor, actually predating all the 1/2A .049s. The smallest of the Zilch series could also use this engine.

Very popular at the time. They sold a ton of them.

Where an Infant was called out on a FF, use an .010 TD now.
