Default Why are my 325mm carbon blades so heavy?

After flying stock blades on my 450 clone for a long time, they finally gave way and I decided to buy some new blades. I found a set of carbon fiber blades on eBay for a good price, so I purchased them. They have a section where the carbon fiber is exposed, and it looks like real carbon fiber. However, upon weighing them, they are significantly heavier than my old ones and even heavier than the weights of comparable blades I found online. They seem to fly fine, but I cannot figure out why they are so much heavier than everything else. Here are some pictures:



Based on this snap, I know that the original blades are definitely carbon fiber.

Thanks!

It could be for various reasons. Different construction, meaning more layers of carbon, different type of carbon, different resin, more weight added. That is not really an unusual weight for blades this size.

Is your heli flybarred or flybarless? Your original blades look like they for flybarred. FBL blades are a bit heavy due to extra weight in the leading edge to help make them more stable and different CG than FB blades. You may have switched from FB to FBL blades. Cheap blades are great for learning, but also you don't quite know what you are getting either.

In my experience heavier blades are nice for small helis, as they help to stabilize and give a more locked in feeling. Unless you aren't able to get the agility that you want, I'd say nothing to worry about.
