Ready to fly.
Plane #1 had different lengths for the nose doublers and tail stiffeners to make room for the battery. I tried to make them the same on #2 but it allowed some additional tail twist so I have modified the plans back to having different lengths. I have revised the build info above to show this but some of the pictures may still show it incorrectly. See steps 8 & 12.
I changed from a ply motor mount disk to a plastic motor stick. See steps 4, 9 & 16.
Corrected the CG listed in step 21.
