Prop failure....... Have you had one??

So you can build a plane from scratch in a day. This should be a thirty minute fix for you.[emoji15]

You just break them when they fall off the stand [emoji12]

And I do a damn good job of it too!

Nope, not how I like to fly. Would be easy to fix and good for someone who is a little easier on their airplanes maybe just general fly around and hover. I would not risk it myself, moving on to something different.

Im just messing with ya. Thats pretty surprising how much it broke up on that plane.

One has to figure it is going to happen sooner or later. The props see a good amount of stress under ideal conditions but then add in we overpower, over fly, and just in general give'em hell.

This was 14th flight, probably did a hundred pop tops, few crankshafts, some KE spins, quite a few vortex's, and lots of waterfalls in 14 flights though!

Exactly the point, it would seem it is bound to happen. I would think the laminated props would be the best, then carbon, I don't care for the solid cut at all. I have never had one come apart but then I am a circle jerk for the most part, a very mild flyer. But I have seen plenty at the field give way, numerous carbons and a couple laminated. I would be interested in knowing why we can't have a metal props, can't be any more dangerous than wood. Maybe it's the metallurgy isn't there in a cost effective manner.

You make a really good point about metal props. I think "in the day" it was thought of "best safety practice" but now we have extremely powerful engines on big aircraft. I think a metal prop would be more safe. Downfall would probably be a very high loading prop.

I don't know about safer. Much heavier for sure. On my race boats, we turn a 6.5" 4-blade propeller (steel alloys) about 10,000 rpm (they are super-cavitating, or surfacing - and run half in half out of the water), therefore have much higher cyclical loading than an aircraft propeller, but... I can see where you would run into cracking problems due to fatigue. We would thin the blades as much as we dare to get both acceleration and top end, but usually when you found a "good one" it would no sooner let a blade go. That usually ends in a similar result as noted previously where the pieces of the engine and lower unit housing go missing. Have a very strict policy to never have anyone standing radially from the propeller (in front with airplanes as well). At least with wood and carbon the density is so much lower your resultant "projectile" has less kinetic energy than a similar metal design, IMHO.

Just....WOW....all I can add
