I studied the plans quite awhile before starting and this is part of the reason why. This is one of several parts provided to cover the open areas.

The plans instruct you to apply two or three coats of dope to one side to make it curve. Because dope shrinks, it makes the wood curve. Therefore it's important to counteract that by doping both sides at the same time. It won't make it perfectly flat but it will most certainly help.

I roll the handle of an X-acto knife back and forth over the piece with some pressure and that gives it a curve.

That is because you are compressing the fibers, effectively shrinking them. If I wanted to curve the balsa, I would just wet it with water.:-)
