Hello. I bought a lot of stuff at a local sale. This engine was included, but there is no name, mark or model on it. It looks like a .049 to me, but I'm not an expert in this hobby. I would appreciate if you can tell me what engine is it. (It comes with an spring starter). Thanks![

My Feedback: (50)

I believe that this is a Testors .049 engine, which they used in their plastic ready to fly control line planes. I think these were made roughly sometime around the 1980's. They were derived from the earlier Wenmac series of .049 engines, which was formerly the Atwood engine in the 1950's.

Though you did not ask about this, I will say that the Testors engines are not held in high esteem by most people who have any experience with them. However I am sure there is somebody out there who likes something about them...

Second thought revision...

I am now a little fuzzy about the Wenmac/Atwood connection to the Testors engine. I also now remember that the Testor .049's direct prdecessor was the McCoy .049.

Perhaps someone else more knowledgable will have something definitive...

Thanks, Silvaire! That was of great help.

Yes, it is the last Testors product engine. There are no provisions for mounting it without the plastic plane it came in.

The standalone version came with a tank and was known as the "Testors 8000". It has a carbon crankcase instead of metal, and is assembled with the cylinder sideways. Running wise, it runs good.

Here are some pics. Lower right is a product engine.

Also, it was shipped in the box upside down. With the cylinder pointing to the outside of the circle, the tank filler points up. Needle valve is opposite cylinder.

Edit: Additional thought. Here is the Testors/McCoy .049 it was derived from. Cylinder and spring starter are somewhat similar.
