I just got a m11x, and purchased a few of the new super response recievers......I binded properly (from what I can tell) but my servos do not work at all. I am using digital servos which are required. When I plug my transponder in, it works fine, but absolutely nothing to the servos. Just to check I tried with my stock reciever and everything worked fine.

Anyone have any insight?

False alarm...I think I got it!

i wanted to try one of those but it says i wont work with all esc's and that got me scared

Please refer to you manual page 48,

if you are using rx-451r receiver with digital servo, make sure it set to normal mode.
the rx-451r receiver in shr mode is only workable with sanwa SRG serial of servo.

The manual says SHR mode is for all digital servos not only sanwa SRG series...

you are right, the manual is refer to RX-451 receiver.
If you are using RX-415r receiver, the normal mode will become for all digital servos and SHR mode become sanwa SRG series only.

Noted, thanks for the clarifications...

So does this mean that with the RX-451r receiver, if you don't have SRG servos, you are actually slower than with the RX-451 because you are forced to use normal?

Nope, Normal mode with 451-R receiver is actually the same as SHR mode with 415 receiver.

Ahh I see, hence normal mode doesn't work with analogue servos.

sorry this is false have try the shr mode with a castle and tekin esc and ace 1015 servo and this work fine!!

Changing mode on the radio is not enough to switch to shr mode, you must re-bind the receiver.
I've tried shr mode with a savox digital servo and it doesn't work at all.

ok,but in the sanwa manual,they said not all servo will work in shr mode!!
for me,my set up is working
