using typical SPAD construction methods and using 4mm. for the wing vs.2mm., how big a plane (Ugly-stik or similar) could be built for a 25cc whacker engine and yield at least "moderate sport style" or "2cd plane" performance ?

yup, that's kind of what I was thinking...... maybe a 5% reduction.

If you get one of the more powerful engines, like a DA50, blow it up to 110%
