This is for any of you that have damaged your aircraft.

My inquiry is in regards to what exterior component of the aircraft you all believe to be the most suseptable to damage? Least suseptable?

I am asking this because I am considering a specific design and lately I've noticed that composites (carbon fiber and fiber glass) are being used more and more. I have been advised against using strictly composites for the entire exterior. But it could be used for a few exterior components - not usually suseptable to damage - to lighten the aircraft.

Any input is appreciated. Thanks
