This is still not solved - the issue appears on both my receivers and I changed to 22,5ms - nothing helps

Re: Lost transmitter connection: what happens?

Yes - when I hear failsafe I always refer to how receivers react when they loose signal from transmitter

In order to program a failsafe (possible on some models) you usually rebind the RX/TX again.
