Sorry for the first post being a issue but this is doing my head in.

Problem, throttle is not moving on GUI and won't arm ESC/s basically no throttle responce
I've calibrated all ESCs twice and will arm straight from the rx just not through the Crius board. Followed the newby directions and checked the board wiring through pics on the net and all SEEMs OK
Board Crius SE 1.9
Quad copter X
Futaba 12z on rx 36meg PCM G3 2048res
Model Aero
ESC Hobbywing Skywalker 20A
Gui:
End ponts 1000- 1500- 2000
reads all sensors and channels Rudd, pitch, roll.. Just not throttle.
On start up Orange and Red solid LEDs then Blue solid LED
Beeps..small tune the 3 beeps
motors twitch on start up.
Just no throttle
HELP..
