Hello everyone I need your help. When I connected one mx-6 transmitter to the rx 391w receiver, it worked fine. But after connecting one more, both transmitters lost signal when output was above a certain level. I don't know how to reset the receiver, so I'm not solving it. Thank you in advance for anyone who knows the solution and I'll be waiting for your response

A receiver can only connected to one transmitter, just to prevent another transmitter could interference. If you did connect it to a "2nd" transmitter it will only listen to that one.

No way you can reset the receiver, only by binding the old info is overwritten.

The second transmitter should still be bound to the receiver, however. Just the first one gets disconnected when the second is bound. But OP reports both transmitters not working properly - and that should not happen.

Oh, and IIRC, Sanwa did have receivers that could be bound to two transmitters - but those were special versions. The normal receivers can indeed only be bound to one transmitter at any time.

Sanwa does support binding 2 different radios to the same receiver on some of their models.

Thank you for your answer! But I've already re-binded it with the first transmitter and tried overwriting it, but the same thing repeats. Currently, I change the receiver and re-bind it to work normally. But it would be great if I could recycle the existing receiver! Thank you again for your response

I doubt it is possible with the MX6 set.

Second RX on different model, Change memory location on MX.

It needs a special receiver, that is currently not even listed on the Sanwa website any more. Pretty sure is was in the 480 series, so not compatible with the MX-6.

hun It's not perfectly clear.... does the receiver not bind to the second transmitter at all, or are you just flustered that once you bind it to transmitter #2, it loses connection with transmitter #1?

I bound the #1 transmitter first and the #2 transmitter, and since then, the #2 has been broken when the output is above a certain level. So I tried to re-bind the #1 transmitter, but I'm baffled that the same thing happened

What output, what level? What do you mean?

My translation misrepresented the meaning. The "output" I mentioned is the forward and backward movement of the transmitter. And the "specific level" is when you pull the throttle trigger more. I haven't confirmed the exact figure yet
