RE: question re: WM's 1/5 Cub
Here's some figures for you....... Zenoah G-20 is 7 1/8" wide from muffler face to face of carb. 3" from center to muffler face and
4 1/8 from center to carb inlet. So if the Cowl is less than 7 1/8 wide you gotta do some cuttin'. Zenoah...4 7/8" from rear of engine to prop washer....91 Saito 4 1/2" ... Zenoah 6 1/4 " from bottom of engine to top of plug 4 1/2 for Saito .91... I don't think either Cub is anywhere near 8" wide ("we need a bigger plane.") I think the G-20 would be better suited to round engine planes like the H-9 Corsair or Hellcat rather than narrow inline or opposed engine planes. Cliff
