    Fantastic job, Jeff. Watching the YouTube video makes me want to build one.

    "For a first flight- the CG is placed smack in the middle of the envelope." I am helping a friend who purchased a BREEZY and has made an engine/prop modification. We have weighed the plane and I made a spreadsheet to calculate the CG, but I can find no information on what the Forward and Aft limits should be, so I don't know what the envelope is. Are the limits in the plans information? The new owner might have that.
    Thanks.

    Bert,

    What you really need is the CG range of the wing that your Breezy uses. There have been a variety of wings used over the years so if you could find that out it would be a good start. Mine uses a Cub wing (from Wag Aero plans) and I used the CG range from those plans. Start in the middle of the range and work your way out. I ultimately did the entire test sequence from the EAA manual at both the fore and aft limits. I could have pushed it even farther but there was no need.
