On the cyclic, they all need to be the same. And yes, any Tx can be used with any servo. Just watch teh voltage of the Rx. And on some MEMS gyros, you have to run a certain frequency with each servo.
It's my pleasure bro. We all had to start in the beginning at some time or another. If I can help with that, I will. If you have any other questions, you know where to find us.
