Hi jongurley,
Your YS 110 should have plenty of power. You may need to add some nose-weight though since it is a light engine. For reference, my Saito 180 weighs around 35oz with the muffler and it balanced my Gee Bee with the stock wire gear and the 600 mah receiver battery mounted about even with the wing bolts near the back of the wing. No lead was needed until I added the Robart gear. If you mount the battery as far forward as possible you might be able to get it to balance on the recommended C.G. with a heavy prop hub. Looking forward to see your Gee Bee. They are real crowd pleasers
