It looks like a C/L Stunter, but it is a pattern plane:

It's called the Circus. Designed for the T.O.C. in the mid 80's I think.

Featured in Model Airplane News. Just another plan unavailable through the rc store.

I can't put a name to it. Just took a look a MAN. A lot of good plans are no longer available.

You guys are too quick. I thought this thing was sort of obscure.

Specifically designed for the '76 ToC in Las Vegas/New Pattern which required square maneuvers (according to the article).
