I guess a gasser would work, the UCD has enough wing to haul almost anything. But why? You guys with the YS110's have some good times ahead of you. I've been flying my .60 size with an old YS91AC since 2002. This engine will hover at less than half throttle, in fact you can't stay even at the low end of the power band without climbing. The 110 is even stronger. That is why my 110 is on a heavier Yak; it needs the power more than the UCD.
