General Fbl Vs. Non Fbl Blades

[k8idx]

Is there any actual difference between main blades for FBL vs. Flybar? I keep seeing blades selling as flybarless. I thought all 3d blades have symmetrical airfoils. Is the only difference stiffness? I put a pair of carbon blades on my old Trex clone with flybar head, I assume that's okay. Also I've never seen any blades selling for flybar helis. So what up with this?

I think it's all a sales pitch, I have never had any problems with either.
I did read somewhere way back that the FBL blades had a different dynamic point of balance ??? No idea what effect that would have, I do know they both break when you plow into the ground.

Not a sales pitch, FBL blades have the CoG further out to the tip than FB blades. Increased swinging weight acts more like a gyro. You can run either blades on either helicopter though. Most will not see or notice a difference.
