In case you didn't know

Besides the radio gear, I just found out personally that the chassis is not the same. Servos don't fit properly, and that little guide piece that sits above the servos that the pin for the swashplate sits in is different. My LHS told me they were the same when in fact they are not. I even measured it with calipers. Just a hair off.

The chassis plate part number for the CX is # BCX and the CX2 is # BCX2
