Default RE: DERIVATIVE, New 2X2

The fuse has holes cut in it for wing and stab. These looked very low on the fuse.

I put the fuse on my reference table and started to measure locations of cut outs.

Nose is square to the table top when the bottom of the fuse in flush to the bench and the tail is raised 3/4" off the bench. The center of the shaft (nose ring center) is 7.225" above the bench top

As I thought, wing is about 3" lower than the thrust reference line inscribed by the crankshaft. A wing this low will require a bunch of dihedral and I just don't want that much dihedral; also don't like a wing that low, a very 70's retro look.

The stab is about 2" below the reference line which is also much too low for my liking. The 1" separation will require about 5 degrees of dihedral in the wing for zero roll couple. The wing I will use has 3 degrees of dihedral...so the 1" separation will be reduced to 5/8"

Looks like I'll be filling and sanding tonight

Here're a couple snaps showing what I'm talking about
