The YS engines are not better than Saito. But the 110 is kinda in a class by itself. It produces approximately 30% more power than the Saito 100. It weighs about 7 ozs more so it isn't without a price. It's about the same as a Saito 150 in power but on the same frame as the Saito 100. It's an exact fit to replace the Saito 100. Makes it very attractive to say the least. The power it gave my 60 size was incredible. I loved it. And it made it a different airplane. It was very fun to fly. It also stops the dripping carb on the 60 because it is a pumped engine. Right now, they are the only engines I have. I'm gonna purchase a Saito 82/100 to go in my UCD46 as soon as gjeffers makes up his mind.

I do think the 46 flys better than the 60. But with the 110 in there is was very close.
