Trouble setting up the RX8

Today I tried to recalibrate my RX8 with Futaba 3PM FASST 2,4GHz radios because radio settings was wrong in the first time... In the first time calibrating was succesful but in this time it didn't work right.

When I tried to recalibrate RX8, it did find the neutral position right and the RX8 did "beep" voice and the LED's were blinking, but when it tried to find full throttle position, it didn't find it and LED's did not blink and there was no voice at all, but when I tried to change the trigger position to full brake, it found it and then it found full throttle...

What is this ?? I tried to recalibrate for many times but RX8 won't find full throttle.

The radio connections and motor wirings to T8 are right, I use sensor harness with T8..

Can anyone help me ?
