What you have there is a stress concentration. The blade's shape is designed to gently direct the stress vectors from the root to the main chord section. That 'nick' is a classic starter for fatigue failure.

Bin it!

imho, it's just a matter of time until cracks start forming from that gash, and the blade lets go in flight. It may not be right away, but eventually. I'd say no.

Unless you come up with something to fill it up, and stop it from cracking. Then I'd say maybe.. If it was me? I'd just get new blades. Cheaper than new blades, boom, mainshaft, feathering spindle, etc, etc.

It's a no for me. If you fly with it, you are gambling with the helicopter and your safety as well as others around you.

If you do not have the confidence to make the call yourself,then the obvious answer is don't fly it.
It is not possible for me to make an accurate judgement from a picture.
I looked at your gallery ,and if you are in the habit of hovering in front of your child,I would vote not to fly the damaged blade.

Why risk it ?, throw it in the trash and be done with it.

If the wings are traveling faster than the fuselage, it's probably a helicopter.

If you are going to fly with it, clean it with alcohol, let it dry, and fill it with epoxy or JB Weld and call it good. Let the glue cure for 24 hours if you can wait that long. Good luck.

The kid pic looks alot different than what it was. The helo was more than 30 ft high and 30 feet from us. And no i dont usually let her hover it and she really has no interest in them anyway!
HeliMax blades are junk period, I would not fly them at their best.
They have to be better than the 10$ woodies that the hawk currently swings.

I would have to say no too. I would hate to crash my heli because of a bum blade.

I'd vote no.

A buddy of mine had his 42% Composite plane slide off the bench and it got a hole punched in the turtle-deck about the size of a dime. Big airplane, little hole right? No worries! He didn't fix it and decided to fly it. A few flights later he did a "blender" and the fuse broke into two pieces because the hole compromised the structure and allowed a crack to start/propogate around the fuse which caused it to fold/buckle under the high stress. He said it even looked fine before he took off that last time. Lucky for him he was only out about 5k dollars and nobody got hurt.

Since then i'm very careful about checking composite structures for flaws.

i'm sure the blade would be alright for a while, but nobody knows how long the fuse is on that bomb.

Yea, I'd have a hard time strapping that onto my heli as well, I say no.

A. Buy a new set of blades for $50 or so.
B. Crash your heli if the blade fails and pay for a new set of blades
anyways along with parts, down time and resetting up.

Make your choice.

Not worth using those blades unless you REALLY don't like your scale helicopter. Since you don't know whether the damage was caused by a hanger crash or a true crash, why risk it? Even if it was caused by a hanger crash I wouldn't use them unless I put them on a POS heli I didn't care for.

So my vote is NO!

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

Okay,
having made paddles in the past from blades I think its fair to say I've seen my fair share of blade cross sections...
That particular part of the blade (at the back near the root) does not carry that much stress and I wouldnt say thats a major breach to the blades integrity, hasnt anyone noticed the re-inforcing which is well away from the damaged area...

Maybe some CA is in order to keep the sandwich together but its not going to peel appart like a banana. Its not going to do anything like fold such as with the aircraft fuse, the high stress areas are re-inforced, its not even effecting them.

Okay, I'm glad people are up on safety but seriously, its a nick in the blade (made by the blade grips no doubt), yes it spins and yes there are some horrific G-forces involved but the main stress goes through the blade far further forward and I've flown worse than that on an R50, near 5 years in the hobby and countless blades says to be their good to go...

Why dont we just throw away every blade ever scratched, tear down all the parks as kids may scratch their knees and ban all fun sports *shrugs*

Just my 2 cents
