Notsu-EZ

Decided to make some tweaks to the Long-EZ. Working around with a 3D model first to drop into OpenFoam. I'm about 8 hours in so far. I'm trying a different approach of designing them in components versus one solid model. Wanting to go with a forward swept wing of about 3-6 degrees to try and shift CG forward. I'd like for the thing to stay on all three wheels without any sandbags. I've already successfully pulled it into FreeCAD so pulling dimensions off of it shouldn't be a problem.

Got some more work. Didn't feel like fighting the formating here.

Bit of a problem here - the forward swept wing moves the COL (Center Of Lift) forward, thus allowing you to move the COG forward, but it doesn't actually move the COG very much. Bottom line: You might still have to use sandbags to keep it level on the ground. Suggestion: Try moving the rear undercarriage back as far as you can. Also, the COL forward move will somewhat lower your elevator authority.

Nice:D Please keep us informed.
