I know it sounds a bit much, at first, but it's not
too much motor. These newer 4-strokes are real
easy to tune nowadays, and are dead-bolt reliable.
But the .70 would be good too.... 
I originally had a Surpass .70 in my WM Mustang. I replaced it with a Saito .91 - only 2 oz. heavier. Mounted inverted, so I had to open up the bottom of the cowl. It looks anf flies great, but I need to add a little more right thrust.
Yes, it rained that day. But just a little.
