Mitch,

may I suggest that you make the bottom of the plan ground level (as shown). It might require a notch in the center portion of your wing LE but I would do it. What is the spacing going into F3 for the wing LE dowels? That's how wide you can make your notch. You should have an inch there to work with - it's all you need provided your wheel is centered on the fuse C/L (i.e., gear mount is probably offset from C/L)

David.
