Very clean set up. My cowl looks like that with grind marks on the nose. It happens!! Back in the day this was a plane designed for a .60. Back then it was a pretty big glow engine. The plane was flown on the wing and there were somt tricks you did to make the plane do what you wanted like a bit of a dive before you did a big loop. Today we are spoiled with all the choices of engines we can use in this plane.No one really gave a lot of thought about installing a G-23 in this little plane. You could lighten up the Zenoah and use it but why bother?? I use the YS 1.20 and I can use up all the sky doing a big loop from level flight. I like it!! Do I need the added power?? NO, but I like it. Glad to see you fought the feeling and used the correct engine for the plane. Looks good.
