Curved Wing Tips and Vertical Stab

This group is pretty slow this Summer, so I thought I would throw
out another question to help us beginners gain some knowledge.

I notice that all the F1D and F1M planes have curved wing tips on the
main wing and on the horizontal stab. In addition, they all have a
vertical stab with a curved configuration.

Does this help with duration, or is it simply the result of building
the lightest weight wing structures possible for these classes?

Does such curvature only help in these ultra-light weight clasess?

Would a Penny Plane, EZB, or A-6, for example, fly longer with curved
wing tips than with stright edges on the wing tips?

Is there any downside to using cureved wing tips?

Thanks for your input.
