I just got a 3Pk 75MHz with HRS RX,
with the HRS rx i can't use futaba s9405 servo right?
You're right ! The S9405 is an analog servo and is therefore not compatible with HRS. I hope you did not get it mixed up with the S9450 servo which is indeed a digital servo...

You only need to change the receiver. No changing needed for the Tx module.
However, remember to get the same 75 MHz PCM RX. If you get the 27 MHz one, then of course you need to change the Tx module to the same 27 MHz.
