Yep, they are very fragile. However, that does help from bending the prop shaft.

I went through a lot of props when I first started... now they seem to be much stronger, as I seldom break one.

GWS does make a "prop saver" and the info on it is here:

If you do a search on "prop saver" you should also find instructions on building your own from various scrap materials. Basically the prop is held on with small rubber bands which absorb the ground strike energy.
