Hi All,
What is the actual displacement of the Stunt Supreme? I have heard they are a little less than ".35". If so, what is it, actually?
Thanks!

Thanks, Steve. I had heard of a .32 or .33 that was said to be an SS and I knew some of the guys here would know.
Thanks!

WHEW! That's a relief! Now you can put it in a real big plane.

Johnson had an engine stamped 32 on the side, then early stunt engine with a plain single S stamped on it. Im using a Johnson 35 in a 59 inch wing span Hi Johnson stuka. It pulls the plane very well about 80/85 thru all the manuvers. If you use a muffler it may kill the power though.
