This is a tiger 60 kit.

The fuse is all glued except for the flooring of the cockpit. (plans call for this flooring to install after the following step is done)
I mounted the fuse on the wing to get the position of the TE holes. ( do this by passing a small drill through the already mounted blind nuts through the TE of wing)
As indicated by others, I measure from wingtips to the tail of the fuse. I get a difference of about 3/16" - 1/4".
I could live with this amout??? But as I sight down the fuse I get back to my original problem with the fuse sides haveing a bow in them..
To try and measure any misalignment on the fuse I took some corner moulding stock, which is pretty straight, and 1st clamped it to the fuse sides at the back of the fuse.
These straight edges ran flush along the sides of the fuse up till it got to the wing saddle. the straight edges run on in a straight line. If the front of the fuse was aligned with the tail I sould have equal space measured from each side of the nose out to the straight edges. I repeated this setup with the straight edges clamped to the sides of the fuse in the nose area. (this is the picture I posted) These measurements confirmed the previous measurements. The fuse hase a bow in it.
Clamping a straight edge to the firewall also indicated the same bow direction although I realize some of this angle could be designed for right thrust engine offset??? Seems excessive to me though...

I just tried putting the cockpit flooring in and I dont see that its going to pull anything into alignment. it just fits into place. could be wrong though.

I also tried laying the fuse on top of the plans. It doesnt look to bad using this method of checking!

I've never tried making these measurements on a plane before (clampling straight edges to the fuse sides ) so I dont know if this is unusual? I will try it on my ARF trainer for comparison.
If not for my original problem with the curved fuse sides I might not have even looked at these measurements.
If this is a problem it would be best to resolve it now as opposed to continuing on with the build???
OR, I'm driving myself crazy for no reason?

On the bright side, the wings and tail surfaces are looking good!

Thanks for your inputs...

This pic shows the two straight edges clamped to the nose of the fuse. If everything was straight the measurements out at the end of the tail should be equal. as you can see the differ by .75" (everything is glued except the floor of the cockpit whick is held in with rubber bands)
