Anyone know a part number for these ?

I need to buy a couple more of these tail rotor blades. They came on the heli when I bought it and they are not stock. The stock blade part number is JRP960051. The heli is a JR Ergo 30. The stock blades are gray. These blades I want are a carbon type. Here is a picture of what I need. And also a picture of my heli

Any brand of blades will work as long as they are the same length as the one's on it now all you need to do is measure them in millimeters and find some that you like I use only MAH blades on my heli's they work great.
