Got some questions for the experienced G62 users. I have a G62 I'm using in a Topflight P-47. It is equiped with the stock magneto and spring starter. It starts easy, idles fine and transition is excellent. I'm using a slimline pitts style muffler. With a master airscrew scimitar 22/10 I get 6400 RPM. The P-47 flies Ok with this set up. It's weight is 26 pounds dry. Tank is 24 0z. It is no rocketship however and it slows down fairly quickly when I put it in a steep climb. Any thoughts on this rpm performance and prop?
