"im debating on buying a 60 2 stroke for what i intended on my siato 72 to do. "

I think you may be a bit disappointed in the performance of the 72 if your putting it in a 60 (two stroke) size plane. For the most part .56 to .72 is usually the 4-stroke equivalent of a .40 /.45 size plane, and most people go to a .91 4-stroke for the 60 size planes...some even use the Saito 100 (remember to add glue to the firewall :-)
