Hello rfw1953

As to the fail safe yes it is only susposed to be for the amount of time for it to restore the signal. Here is my thoughts and I have heard from several fliers around here that when thier airplane went into fail safe, they never recovered control so the signal was never restored. My guess is it never got a good enough signal to regain control. and total losses for several 40% airplanes around here. My thoughts are if I can get any type of signal to the reciever to get some control inputs to the airplane fighting a hit I am better off than not having control at all.
Now if you are flying competition pattern or IMAC you would be better of with PCM because you are less likely to see any small glitches with it as you might see with PPM. My preference is PPM as again I have seen people around here lose airplanes with PCM and some have seen us fly and ask what recievers we are using and tell them HITEC supremes and they seem suprised but now several have changed to using them. This is all preference both will work just fine but I do recommend to use a ppm reciever to set up and test the airplane on the ground before installing the PCM reciever. I also feel that the required having the fail safe setup to give low throttle and down elevator and left aileron as some suggets people say different things is unsafe setting a fail safe to do certain things is asking for troubl depending where you are and how high you are set the fail safe and watch it headed toward the pit are depending on your position on the field so I do not see a safe fail safe setting other than hold from the last inputs but that can still be unsafe, but I think all of it is unsafe not saying any of it is safe because it is all man made stuff and all is prone to failure no matter what.
This has been a highly debated subject and all of this is my opinion and I am sure that by tomorrow evening other people will be flamming what I have said but all of it is just opinions you have to look at all facts or semi facts or statemenst made and judge for your self what you think is for you. I fly mostly 3D or am Learning ????? and all planes I fly 30% and up use 2 recievers and seperate batteries and switches for safety of the airplane more than to distribute the servo load as I have personally landed an airplane on 1 reciever working only and it saved a 2.6 meter FC from destruction but that is another flame war to start.So it is entirely what you can make of other peoples opinions and not just people telling you to use one or the other get reason for it and not just use this and that. If I have not elaborated enough you can email me or post again with any questions I will be Glade to add my opinion and opinion only no hard facts I ant no Inginere.
