Mike and other respondents,

Just a point of clarification. I am taking part in this discussion to help solve a potential problem. I can easily solve my immediete problem by connecting my two canard elevators in to two receiver outputs, or if I felt confident in the buffered Y, use one of those.

I am really impressed with the Hitec digital servos to this point. I have a Hitec programmer and can set the servos up to be a match for all my surfaces.

I also am impressed with the Multiplex receiver to this point. The combination of versatility of both of the hobbys latest technologies is astounding.

However, when I connect the combination in a well used configuration (two servos Y'd) and find a problem of non compatibility, I start to be concerned. Is the Multiplex rcvr a borderline unit? Are these particular Hitec servos borderline? It makes me wonder if there is a marginal specification that could drift such that a working unit today will be a non show during flight. I have too much invested to not be concerned.

So, I want to know what is happening, what is the problem. It's looking like there is more than one brand of receiver with the problem (At least Multiplex and Hitec). I have two Multiplex 12 channel receivers and they both respond the same way, same problem. And multiple 56xx servos exhibit the problem. This problem should be easy to solve.
