I have a Escapade .60 with a SV-17cc engine (1.0 cubic inch) on it and the plane weighs in at about 9 and 1/4 pounds of weight. I don't think it would have weighed all that much less with a big glow .60 engine or glow four stroke engine either.

My Escapade .40 with a NGH 9cc gas engine weighs in at about 6 pounds too. It flies really well with the engine on it. But it was a tight fit, as I had to put the CDI module up front under the engine. My low wing sprt pattern plane weighs in a little heavier at about 6.5 pounds and it flies well with the little 9cc gas engine too.
So I think having a model go 7 pounds or more in weight might be a bit too much for the EVO 10cc engine. I don't thinkI have ever built up a plane ever that came in under the weight the plane manufactuer claimed it would weigh.
