X5HC props fitted, but very breakable

I’ve fittted X5HC props on my X5C and they say that they are better.
And, yes they are. more lift, and a minute or 2 more flighttime.
Untill you hit something, they cannot handle anything at all.

After 4 flights 1 prop broke as I had a sidewind landing and 1 prop hit the ground.
Too bad, they are perform very good!
