I am pretty much the same as Zippi. I run a Zenoah g26EI. I am running a APC 18-6W prop. I use the same exhaust but I sent my engine to Ralph Cunningham and he modified it so I could turn my carb 180 degrees so the adjustments are away from the prop. I put a hatch in the bottom of my Rascal after the ignition battery that was mounted behind the firewall exploded blowing out 3 walls of the nose. I now have the electronic ignition mounted in the nose but not wrapped so the heat can dissipate easier. The battery is behind the cockpit area. There are a few other modes various builder have added and it is worth you time to read through the entire thread.
