These props are extremely rigid, which gives you all the punch you need. However, being so rigid, they will explode into a million pieces if you crash. I crash plenty and break them all the time, but they definitely fly better and smoother than any PC prop I have tried. TONS of get up and go!

Great props! They are lighter than all the other props I have used of the same dimensions. They spool up quicker, and have a stronger punch out, and a quicker cyclic respons than my old props. They are a little more brittle than what I'm used too. But I don't mind, because I haven't destroyed a motor since I have started using them.
