For a plane she could build herself, and also be strong enough to survive for several seasons you might consider the SIG Goodyear racers. They make a Buster and a Shoestring. I don't know how true to scale they are but the outline is close at first look.

They have solid sheet wings with an airfoil sanded in, and look good with the scale paint job. As a bonus she could also race them.

Just a thought,
