Hey Bob, here are a couple of pics of my H-9 PnP Cub with a Saito 72 in it. Since mine was the Plug and Play version and came with an engine installed I just used the mount the way it was. The Evolution 46 that came in it was junk and I got a new one under warranty but decided the Cub needed a four stroke. I had to drill another hole for the throttle pushrod and rotate the carb but installation was pretty straight forward. I kind of wish it was side mounted at a 90 degree angle but that would involve more work than I want to do.
