Seems like most Four Star 120s around this area flew with glo 120 2 or 4 stroke engines. Most seemed to be a pretty good match and flew quite well without excessive engine weight. I would think the the DLE 20 would fit right in there performance wise. The wing area is huge though so a 30 wouldn't be as far off base as many would suggest. More power doesn't always have to suggest 3D performance. Some of us just like a quick climb up to unlimited inverted flat spins, etc.
