Prop Question - "The Fix"
Anyone have a landing where the prop slightly strikes,
but not even enough to stop the motor. When you eyeball the prop it looks fine, but upon further inspection, you notice a hairline crack. You have to put a ton of force to bend the prop back, and when you do it exposes the small split in a top layer of the prop. Has anyone just slipped some CA into it, and rebalanced the prop? Is this cool to do? I realize the stresses a prop goes through, but sometimes I just hate to loose a prop for a tiny little split. Give me examples of the GOOD and BAD of doing this please! |

Re: Prop Question - "The Fix"
Don't know if the CA would work, or not, but can you imagine what would happen of the prop let loose in a hover, 10 feet off the deck? Or worse yet, running it up on the flight line.
Maybe a new prop is the answer...can you say 3-blade for Mr. Rogers? |

Re: Prop Question - "The Fix"
I've seen what happens when you lose a prop blade mid air on a 3W 150 that was pulling a H9 Ultimate. Luckily the plane came down in one piece, but nearly every glue joing in the thing needed glue reapplied. It made a real mess of a plane. The departure of this blade was cause by the spinner coming loose and as it came off got caught in the prop. Do yourself and others around you a favor and just buy a new one. It's not worth the risk of throwing a blade, espically on the bigger stuff.
Neo Out!!!! |

Re: Prop Question - "The Fix"
I've CyA'ed the crack, and no issues. Just re-balance, or check the balance, and IF it needs it, then re-balance. Ohhh, this is on WOOD PROPS ONLY!!!!

I decided to make this one a test prop, so I was twisting it, and bending it.. and no breakage. I also slapped it on my ZDZ 50, and ran it up to around 7000 rpms, for 10 min... 1 piece, no sweat. So i think I'm cool... rock on CA!! |

Re: Prop Question - "The Fix"
I would continue to re-inspect the blade. A crack or delamination can re-open or re-appear after it has been repaired. I wouldn't like to take any chances with an expensive plane or the people around the plane just for the sake of saving $50.
