I'll chime in as I'm flying mine with a VT80.

It's more thrust than is needed. I also had to make major
mods to fit in a larger fuel tank. I have now cut down an xcalibur fuel tank to give me 2.4L as 1.7L was not enough.

The SM version will fly fine on a 60n engine. I am cruising around at half throttle most of the time with the VT80 and it goes just nicely. Full throttle is nice on the verticals but considering there is one flying on a K45 it shows that the airframe is fine on a lower thrust engine

I wouldn't stress about weight etc. It's a terrific flying airframe, stable and a delight to fly. (Well my SM version is)
