Well, the shift must be compatible.
Are you wanting to use the TX only or the receiver as well? If you use the receiver as well as the tx we can probably get you set up, but I think using the TX with the stock rx is going to be hard.
Your 7202 can do 3-servo eccpm mixing, right?


The CP as opposed to the CPPro, has an integrated 4-in-1 unit combining the rx, the gyro, the mixer, and the escs for main and tail. There is a hack to separate the rx but there is a better way too.
