Big ned is right, assuming you have the 60 size you will need a regulator (cline or iorn bay) just to keep it from flooding because the tank will be higher than the carb on the 100. or if you can be quick at starting you can keep it from flooding while fueling with a great planes easy fueler valve but as soon as you unhook the fuel line it will let fuel to the carb thus you dont need to prime, just hurry and start. i have the saito 100 on mine also and it flys real good, i personally dont know about the ys110 YET, but i have a real big suspicion that Ned is right. and i just use jr537 standard servos and they have worked fine but im not real hard on the plane, the hardest i do is a blender and they are doing fine. you do need to upgrade the pushrods to 4-40 or carbon fiber and i would use dubro pinned hinges.

good luck
