My Dazzler has a OS 46SF (the predisesor to the FX but is just as heavy) and it flies great, might have to add a little to the tail but when you want or need that power it IS there. Put a 12x4 prop on it once it is broken in and have a blast. Just keep it on low rates till you get used to it and the low pitch prop is to help it from going to fast and getting flutter not to mention the unlimeted verticle you will have. When landing, this plane will slow down real nice and if you have a computer radio add expo to soften the controls a little. And when you get the hang of flying it turn up the rates and it will spin like a top with full ailerons.
