Kadet Seniors with a 91 will be great. I have one with a OS-91 4-stroke and it is a wounderful plane. I built it with no dihedral and it is a tail dragger. It is a four channel (you know with ail.) you can do some 3D with it , it will definately pull itself out of a hover.
I built mine so long ago, but I don't believe I put any right thrust in it.
Hope that helps.
