Hello Mark, your YS should be a perfect engine for that. I'm running a Saito 91 and honestly it does not have authority to pull out of a hover but it does hover great. I'm using Fut9402 on the tail and Fut9303 on Ails. The kit comes with a slim tank and putting it on the CG area is doable, but requires little more work. Mine weights 7.6lbs. I would also recommend replacing those 2-56 rods as they bend easily, I'm using 4-40 and works fine. Good luck
