RE: Engine setback on a ultra stick 60??
The 95 will take a larger diameter prop or a higher pitched prop of the same diameter. This could lead to higher landing speeds or prop strikes when the tail comes up. Not a big deal, but something to check before flying. The CG is about all that is affected by moving the motor, but you are gaining more power/thrust. The 95 at idle will generate more thrust than a 60 at idle which will cause a higher landing speed. Again not a big deal. Program some flap into it for more drag. A straight wing like the US should balance at 25-30% of chord.
