I’ve given it a shot the control surfaces did work out fine@HistoricBirds

@CursedFlames well neither am I but I can still learn try going here

@HistoricBirds Oh sorry, you can tell I'm not an expert in xml :P

@Rub3n213 @CursedFlames noooooooo dont do that!!! the hinge distance means your control surfaces don't work instead you should use a structural wing with control surfaces enabled

i can do it if you want

I’ve tested it out, seems to not have any flex at all, this might be it! Thank you @CursedFlames

0 mass is simple, however the not bending or breaking part could be difficult.
Here's a wing with higher health and 0 mass. I also changed hinge distance to 0, I'm not sure if this affects wing flex or not.
