I agree with w8ye. However, I like to stay in the upper range of recommended engines for an airplane. Sometimes that little extra power saves an airplane. You can always thottle back and have that extra reserve. I got my mustang on its wing tip two feet off the ground on landing. The power of my 1.80 and lots of rudder saved it. After my knees stopped knocking together, I landed.

I'm with you and Jim. I like to buy the largest displacement engine in a given crankcase size. It is more economically versatile. I'd go with the .82. It puzzles me why Saito even makes/sells the .72 any longer. It's a nice engine, but when the .82 is available for just a little more...
Of course, I should talk. I bought a Saito .56 some months ago and it too shares similar mounting dimensions to the .62, .72 and .82. So much for making sense.
