The ST .40 and OS .40 LA , although run well are not noted for power. Its a coin toss as to which one you want to put in your plane.

Hello everyone!
I have an avistar trainer that I flew this past year with an OLD Enya .45 in it that my father- in -law gave me. Long story short, this fall the old enya gave up and is officially done. For x- mas, my wife has gotten me a 4*40 kit with an O.S. .40 LA (combo deal from Tower $118) and then she got me a Super Tigre .40 to replace the old Enya in my trainer. (Even though I know what she got me, she still won't let me have all this stuff till x- mas!) I've heard that the O.S LA engines are rather weak. My question is should I put the O.S in the Avistar and the Super Tiger in the 4*? Is there a substantial difference in the power that these 2 engines output? If so, I would rather have the more powerful engine in my 4*. Your thoughts are appreciated.
