I WAS planning on using the TX with the stock RX... that isnt possible then? The 7202 can do 3-Servo exxpm mixing. My Futaba Tx can control the stock Rx but the JR isnt working the same. I know the Futaba is negative shift and so is the unit on the Blade CP most likely. I just wasnt sure if the PCM JR-7202 could switch between positive and negative shift.
