Rear wings

[ORBB]

Hej guys,

I might be in the wrong part of the forum but I have a question about rear wings in general.

I'm racing largescale and was looking for a way to improve the wings / lowering the weight of the wing perhaps.

If I look towards 1/10th scale offroad most of the wings are quite simple lexan wings, compared to the 1/8th who have bit more complex wings. Why is it that 1/10th is still using these kinds of wings ?

Looking forward to all different replies here

greetings,,
