The leading edge looks like a small nick. The trailing edge at the root is of no consequence since there is no load there.

The way to check the blade is to bend it over your knee and see if it makes crunchy sounds or bends in a non-uniform way. Twist it also to check for problems. Check for trailing edge delamination while bending and twisting.

I use beat up blades to shoot autos until they get dusted chopping the boom off which happens about every 10-20 attempts.

Do like Stet says.

They look fine to me if they pass the bend test. You could fill out the small scratch with some CA, or epoxy. Just make sure that the CA dosent melt the form, if that's what is used for the core!

Otherwise, I will buy them- cheap!

$100 blades that go bad risks a very expensive heli.

I generally do not have good luck. So I just throw them away.

Plus there is a safety factor since I fly with other people.

I know if they were mine, they would be stirring paint as well. No need to risk your machine, or someone elses life in an attempt to keep from having to trash those.

Build it, fly it, crash it. Repeat as often as needed.

well i flexed the blades pretty good and i cant get any "crunchy" sounds... i do have fiberglass resin here, as well as epoxy for that little center piece... it would be going on a scale heli that does little if any aerobatics and not high rpm. of course, since its a scaler, i would really not want this thing to self destruct in flight.

blades

Here's one idea for you. Do a 'tap' test around the area to determine the extent of damage. Take a coin and tap the surface of the carbon - it should produce a fairly clear sound. Now do this around the damaged area. If there is any delamination around the damage the sound will more 'dull' in its tone. It may tell you a little more than you can see without disecting the blade. Like somebody else said, the leading edge sees a lot of stress, I'd be hesitant about repairing this unless I was very sure that the damage was just cosmetic.
I repaired a trailing edge recently that was damaged when the blade swung around and hit the blade grip. Friend of mine gave me a great idea for filling the little nick: fill the area with resin, then put a piece of clear scotch tape over it. This makes a little 'mold' over the area and if you do it right you can hardly tell there was any problem there.

If these are from a crash I wouldn't yuse them. But if you bumped them at the back during transport they are probably OK.

Chips don't bother me, however seeing part of the blade de-laminate would concern me. But as you're using them for mixing ancamine/ancamide and resins no problems

well if you look at the center of the one blade (first photo) the resin coating is definitely cracked, and the trailing edge is just scuffed down from making contact with the pavement. i wouldnt mind some LMH flex-blades right about now, i can tell you that.
