Warning: rc timer carbon prop break in flight

[powerlord]

Just had one the rc timer props just break off in flight.  Through the quad into a high speed run in that direction.  Smashed into trees and broke gimbal off and legs but no other damage.  Motors still spinning thanks to rtl safe mode making it at least easy to find.  I';m going back to graupners I think.

WoW - not sure how that occurred, possibly overtightend and caused a crack which weakened the prop?

I have just started using carbon fibre props form rctimer after having them sitting around for so long and have found they sound ';glassy'; when spinning - bit like when you flick a glass when it is empty. However, I had a major crash with them on and they did not snap, if anything, 1 of the blades delaminated so I am convinced of their strength and their cost!!!

Having prop nuts without a washer is asking for trouble as the points of the nut can set up unwanted stresses in the hub.  You can get away with it with DJI props as the design of the hub is different.

 it';s not gone at the nut though.  It';s about 3mm out from there.  That was my initial thought too.  No over tightening. Crash is one thing.  Spinning at  god knows what a second : far higher forces involved.

Exactly the same thing happened to me dude! Regardless of all the people out there saying they';re great props, i think they';re absolute crap!

Typical Chinese manufacturing Quality control. I just cant trust cheap carbon props.
