Bob, you have my attention!

First, I am trying to imagine a plane that would do the AMA 1/2A pattern with a Testor's engine on it. Does it show an engine on the plan?
Second, I am guessing the plane was called the "Ambush"?

I would love to find out more of this thing you have.  I only recently discovered that Testor once kitted C/L kits back in the 1950s! The sheet planes even had a strange set up for moving the elevator.

I can hardly wait to find out about this one!

Not sure if it is relevant but there is a good thread about Testors models here:

Very interesting, I hadn't never heard of this plane.

The plan was offered free from Testers when they came out with the 8000 series engine.  That much I did remember as I was always looking for free.

Hi Robert,
I was just looking at a 1979 issue of Model Builder and in the Fuel Lines column, Joe Klause did some RPM tests on a number of 1/2 A engines, the Testors 8000 being one of them, With 15% fuel and Cox 5x3 prop, the Testors 8000 turned 17,200 while the Cox Black Widow turned 16,100 and the Golden Bee a 15,600.
Looks like the Testors 8000 is a pretty gutsy engine and should do well on a 1/2A stunter.

Orv, Thanks for that. Now try to find one! I know I don't!

All kidding aside, I would build this one just for one of those 8000 engines if I had one!

The Ambush is deffinatly designed by "Wild" Bill. He designed them in several sizes. About 15 years ago, a .15 sizews published in MA. I may have digital files from Bill for the ambush, and another 1/2a design that was constructed from 1 sheet of balsa.

That one sheet plan sounds interesting! Would like to find out more! Because of making it fit on one sheet it probably isn't much to look at in final form but something simplistic. Owing more to economy and function rather than form.

George, thanks for those good pictures and info! This topic just grows more and more interesting!

Just last week I had my eye on one of these 8000 engines on that big auction site and thought I might get it cheap but the seller, who runs and tachs his engines said it was hard to start at first, then  when running its best only tached 11.4K on it. I checked today and it sold already for the opening bid.
