Someone posted using a Saito 100 in theirs. They said that it would fly it, but you would have to make a shallow dive to get it to loop. It would be very scale and not leave a lot of room for error. I have never owned either engine, but from what I have read YS typically puts out more power than other engine in the same size range. So I think it would get it in the air, but the performance would be in the eye of the owner.
