I had made 2 - 1/4" balsa "filets" that are way more aerodynamic that I have glues in place beside them.
This plane is for my son whose studying for his Master's Degree in Aerospace Engineering who insisted that I add the filets. He design them as part of a class project so I think it has plenty of "brainpower" behind it.
PS His school ends in about 5 weeks so if you have any job leads please let me know!
