A saito 72 would be great, I am sure that a 62 would fly it fine. The 82 was certainly more power than needed, and way above scale. I merely obtained a .91 and wanted to use it. So, I am currently bumping down the engines in my planes 91 in place of the 82, the 82 in place of the 72, the 72 in place of the 56, and will find a plane for the 56 in the future. The 56 is just too big to replace the 40 in my GP Combat planes...

The 82 hangs out the bottom of the cowl very little. I opened up a hole in the front of the removable bottom plate to allow air to flow across the cylinder.

The 72-82 requires my battery strapped to the side of the fuel tank, a whole bunch of nose ballast, and the heavy stock muffler. (I usually use the light straight-pipe exhausts)

You could easily use a Saito 125 in this plane or even the FG-21 and the ignition box and not worry about CoG
