As soon as a good signal is received it
should come out.
I think the problem is that the PCM RX sees bad frames and copes with it very well until it just can't process it any more. At that point it goes into failsafe and usually doesn't come out because it no longer has those few good frames to fall back on. This is in layman's terms as that is what I am
. At least with a PPM RX you should get some warning before it goes into failsafe.
I have flown Futaba 1024 PCM since it started and would fly nothing else.
A PCM receiver WILL return to normal once good data is received.
Test it on the ground...turn off the TX...failsafe engages...turn it back on ...it works again.
If it dosnt then you have another issue.
In flight when signal is lost the RX will drop failsafe much faster than the ground test of switchig of TX and back on again.
This because in that test the TX has to re-boot.
A better test is to have the model on the ground and have somone else stand along side with the same frequency.
When they switch on, failsafe engages, when they switch off conrol is restored instantly.
My preference is Throttle to low..all other controls hold. This is also the recomondation of the UK JMA.
