i think they are strong
The tip of the props are soooo thin and flimsy they get misshapen very easily causing lots of noise. I felt the need to use fingernail clippers to remove the tip, now they sound fine and the do fly pretty well though I think my tune could be better for them as they do get a lil more propwash than my 5149 that are the next closest size I have to these.
