Okay, I read the manual (raining today) and I was able to see the error in my ways. So I started over again with a clean model memory, selected the flying wing with 2 ailerons. I left the default Rx Ch settings and hooked up the servos accordingly. I have functional elevons and everything moves the correct direction and distance relative to each other.

HOWEVER: when the elevon servos are driven to the stick limit (less than the servo limits) then the servo stops there for a LOOONG time. This is very disconcerting and would result in a definite crash, as the time of sticking is from a half second to infinite, forcing the Rx power to be shut off, in order to reset everything. The servos are JR 8411's, and worked perfectly well on the 9ZAP and R149DP. Other than the 14MZ and its RX nothing has changed. Anyone have an idea?
Thanks,
Len
