Bob, or anyone for that matter, do you know where I can get the prop extension for the G62. I am converting a 1/3rd scale cub to use a G62 as the current engine is underpowered. It's obvious that I am going to need to move the engine back about 2" to make it fit in the cowl, so some sort of a prop extension will be required. Also, any recommendations on a muffler. I want something very quiet, and someone recommended a Slimline muffler.
