OK Steve, here's one. OS 1.20 works very well at 4500' elevation. Simple by the book install. Just luv it. Smooth, easy to land, a very good plane and investment. MM
MM,
For clarity, are you using the OS 120AX (2 stroke) or the OS 120FS (4 stroke)? I have both and I have a DLE-30 and not sure which to install on my still in the box new GP Waco. Thanks
Howard
