Not sure about the prop because I run a O.S. 120 Surpass on my CG Ultimate. Just want to say I love that plane, and since it is usually the only bipe at the field, it gets a lot of attention on the ground and in the air. Hope you have as much fun with yours as I do with mine.

Ive got the kit built ultimate but with a ys120ac and its using a 16x8 prop at the moment. I would think you would want your engine to turn in the low 9000 rpms maxed on the ground, and it will be happy. I would try a 14x10 and a 15x8... you will just have to try each prop to see if it flies the plane the way you want it to perform. One of these 2 props should get you going, and have a fun with your ultimate!! Just dont slow it down too much on landing or slow flying, as it will possibly fall out of the sky... dont ask me how I know this, lol
Hope this helps,...
John

I had a CG Ultimate with a YS 91. It flew great with a Graupner 14x8
