I have one with a 3W 106/ supersonic mufflers. It makes really good power on a PT Models 27-10.
It is a very good flying plane. Very good value for the money too. It's a 3D beast and flies some very good precision.
I've seen it fly with a DA-100 and even though it's good power, I would go with something more. Maybe a DA-100 with pipes, or 3W-106. I'm not sure how good an 80cc would pull this plane around.

It could be a little lighter but you definitely don't feel it. Flies pretty light.
Any questions you may have feel free to ask, or shoot me a PM!
