I have one of Todd's canopies for my Long-ez. The plans call for a lip, but Todd's does not come with one. I made mine exactly as Wayne described without issue... I used the same jigs that the plans called out too... well actually I shortened them a little so that the canopy would be a little wider and a little easier to flair into the strake.
If you prefer the lip you may purchase the canopy from Aircraft spruce: P/N 05-01154 (clear) or 05-01155 (tinted.) I've assumed that these have the lip, but you'll want to call and find out for sure, as I've never seen these in person.
Warm Regards.
Ray.
