I cannot arm ESC.
If i use pass thru mode I can calibrate throttle hi and lo, ESC beeps ok, motors spins on trottle stick.
But when i boot APM2.5.2 it arms but no response from ESC and led light not goes on, and not any beep sound.
So when I measure voltage on motors output pins it have 5v on signal.
To compare i measured signal pins on receiver's side it was .20 or so.
How i can make it working?

Well i figure out everything my self.
In case someone need an info, I did reset board completely, reflash with plane firmware, then back to copter, tune everything from scratch, now its work as it should do.
