Default True redundency

I have just finished testing a true redundency using two receivers, to one servo. Either receiver goes down, for any reason, the servo keeps on ticking.

That means that you don't have to have a half plane on one receiver and the other half on the other receiver.

Kind of a cool idea for those really big birds and turbins.

Actually, anything with two receivers.

I was allways against using 2 receivers because it gave a false sense of security, with the airplane operating on only one side of the aircraft
This way, loose a receiver and you retain full control.
I have been working on this for months.
You also get the benifit of the Fiber Optic extensions which in itself is a great fight against glitches.
So you get a lot of bang for the dollar, wouldn't you say??

What happens if you pull the crystal out of one recevier (I.E. crystal failure)?

If they are PCM and one goes into lockout or failsafe what happens?

I tested this last night, the servo gets very twitchy, but still with control

But then at this point with any other system it would lock out completely.

For any other reason such receiver failure, for any reason, such as bad battery, switch harness (most likely) then you would notice a very slight change in trim, which would be a tell tale that something is wrong and you simply come back home with full control, not half an airplane contol, which would be disastrous to say the least, mostly the large warbirds.
