I have a Global Ultimate with a YS .63.

Built it with everything stock except I replaced the cheap wheels and metric pushrods.

I love it. It is easy taxi, take off, and land. It flies as gently as you wish, but will also "wind up" for you.

My YS. 63 gives great vertical performance with a 13x6 prop. It will hang on the prop and even pull out slightly.

You will want to put extra epoxy on the landing gear block...mine popped out on a fairly smooth landing.

The Saito 72 should be perfect...however, I put two ounces of lead on the tail to help it be more aerobatic. I gaurantee KYBLUE's plane is slightly nose heavy, unless he put the servos in the back, etc. But even if so, this plane will fly nicely either way.

Go for it!
