I'm getting ready to pull a Saito .91 out of my 4*60 and bang it into a Funtana. From what I've read this motor should do the trick, although I'd much rather put a FA-100 in it. $$$'s are an issue with Christmas around the corner. I don't want to moth-ball the 4* and am looking to get similar performance out of another (cheaper) motor. Can you guys recommend any 2-strokes that might work well in my 4*. Not too familiar w/TT's, Mugnums, etc..
