Thats really no big deal at all.
Yes it is a big deal!
When I was a beginner, I did make some G forces with my Shuttle ZX and woodies because I made a lot of dumb thumb mistakes and tried to recover the heli from crashing to the ground.
Taking this into consideration, a repaired blade is not a safe and good idea!

WOW! I never thought this message would go this long. I do appreciate all the suggestions.
I'm going to show them to a local flyer and get his opinion as well.
It really is a very small defect and is on the trailing edge of the blade. The pictures do make it look alot worse than it is since I took the picture in Macro mode.
Being a heli newbie, I'm not that allknowing when it comes to heli parts and the damage so I thought I would ask..

Thanks again,
Rod

The crack is very small, at the trailing edge of the blade and is non structural. It is nowhere near the lead weights and I would say that your'e safe to use a little bit of thin CA.
To be sure you can pull the shrink wrap off of the blade and inspect the damaged one fully and then put new shrink wrap on, BUT to keep from getting flamed to death I will also add that the rotor blades are the most dangerous part of the heli and that if your'e not sure about the crack at all to just put new ones on.
Very minor dings on woodies IN MY OPPINION are repairable.
If your blade had a chip taken out of the tip, or if the crack was much longer than about 3/4 to 1 inch long I would say replace it but it is only a small crack.

Dave

PS the safest way to treat any part that is damaged in any way is to replace it with new but some things are repairable to a point and others you just don't want to risk it. Woodies are repairable to a point in my oppinion.

I would not hesitate to REPLACE what is in reality the highest velocity part in your flying heli. A simulator will ensure your blades last longer too!!

Seeing that the average heli pilot (both beginner, and advanced user) come from a variety of backgrounds, skill levels/knowledge, it's hard to say "sure, just repair it". If you had a pair of Carbon Fiber blades you broke, and you were a technician that frequently worked with Carbon Fiber, and have the know-how and the expertise to repair such an item, to balance it perfectly, and to make sure the airfoil is perfect and free of defects when you complete it, then sure, go right on ahead and to it. If you however are an accountant, WTF do you know about repairing Carbon Fiber? The last thing you want is an Accountant trying to use epoxy resin on his fiber blades and "hope" it works.

In the case of any broken part on a helicopter, there are huge cons of reusing the part. That cheap part could cost a very expensive crash, and that very expensive crash is already high enough risk being a new pilot. Having a failure on the ship just makes it that much more iminent.

That said, for $30, you could get fiberglass blades 550mm... You can prob find someone selling new woodies for $15. Or you could attempt to repair them, try to learn to fly on blades that aren't perfectly balanced and properly repaired and have things such as vibration issue's and such, or possibly other defects within the blades that will cause them to break in the air causing a crash.

When you get into helicopters, there is one fact you have to face from the beginning. That fact is this is NOT a cheap hobby, and there is no half assing things in it. You can't cheat yourself and try to save a few pennies here and there as in the long run you will spend more money repairing and replacing things due to your initial cheap investments.

Now that's just the direct money factor. Now you have to look at safety.

If you came out to my club field with those blades and wanted to fly, I wouldn't let you even fire the engine up. Anyone else at the club would probably do the same thing. They will not want you to risk the life and limbs of other members, and the chance that the club gets shut down due to poor safety, simply because you felt like saving $15. I fly a Sceadu with 600mm blades on my heli and a head speed of 1950. If there is any minor defect in my blades at all, they will more then likely come apart in the air, and if it was headed in my direction with some altitude, and the blades came apart, suddenly I'd have a 5 pound object falling from 300 feet straight at me. I don't know about you, but I wouldn't want to get hit by that... I value my life and I think my life is worth more then $15.. (well at least on some days *grin*) =)

So the plain and simple answer to your question is "When in doubt, replace the part" Your life is worth more then a pair of woodies.

I agree with RappyTappy.... Why not just bolt 'em on and "scuff 'em" a bit to even out the tips?

Just stand back a bit further than usual....

Gotta love it!

From the pictures it looks to be a very small crack in a very non structural place.
From the way some of you have been going off, if you scuffed your carbon blades do you replace them because they're now damaged.
Now I fully understand about safety and I DO practice being and flying safe, but come on lets be realistic the damage is not that bad.
Look at the pictures again.

If CY can repair the blades he damaged at the 3d Masters then I really think that a split on the trailing edge of a woody can be cynoed, re heatshrinked and flown till it gets properly damaged in the next wipe out.

Its not the $20, its the principle. Don't be fooled into simply replacing components which have suffered minor damage, unless your personality requires that you replace your car if its involved in a minor fender bender. Just ensure an effective repair and go fly.

I have fixed worse..

Howdy!!
I don't use wood blades anymore, but when I was learning I used up plenty.. I don't think anyone who can't auto should be running composites.
I have repaired blades much worse than what you have shown in the picture. Just fix em' and fly.. Use them for auto practice if it makes you more comfortable..
