The tool should match the purpose. This plane can tolarate Saito 100 as it is a light engine. However YS 110 (~735 gr w/o muffler) is totally out of scale. This engine rocks 8.5-9 lb planes and way to much power and too much weight for a 5.5-6 lb plane (with110 it may be 6.5-7lb). My opinion is the feature that makes this particular plane unique is its light weight and wing loading. With that combiation you may rocket out of hover but the hover is not the only 3d trick. If I would make an other one I may try a saito 82 and perhaps this would be the best glow combo.
