Spars installed. Make sure as you put these on you have the fuselage centerline plumb, so the wings will be aligned properly! You can of course do this by sight, but I have a tiny bubble level I held up to the center while the front spars rested on the mat to adjust things. Then the rear spar will go on last and again put it down on the mat and adjust the fuselage until the front spars are the same distance from the mat. Make sure you orient the 2nd spar such that the color part is facing to the rear.
