I have a couple of questions about the Blade CX3 body conversion.

In a youtube video I found, the poster states the title of video as "CX3". He mentions it has an ESP boom upgrade. http://www.youtube.com/watch?v=N3shGg0Tofs

Now, when I search for the ESP boom upgrade, the ad I find says it is for the CX2: http://www.ehobbies.com/esph1000.htm...mpaign=froogle

Could someone confirm that these parts are interchangeable between the CX2 and CX3?

Could someone maybe confirm all of the parts that are interchangeable between those two models?

Thank you
