Hey D:

Funny you should mention building the wing with less dihedral. The measurement technique, suggested, to insure the joiner has set the two wing halves at the proper angle, failed. There should be 5 1/4 inch, from table top to highest point on each wing tip, plus or minus 1/2 inch, with the opposite wing lying flat on the table. I just barely managed 4 inches, although, the measurement from wing tip to wing tip was exactly 61 inches.

I didn't realize the tolerance were so loose. I wouldn't even call those numbers, ball park figures.

I've asked support for help to define the error. This will be my grand daughter's first real model airplane & I really want to make sure, everything is right.

Do you recall what your numbers were?
