Servos are not completely moving | Pixhawk 2.4.8


*Board : Pixhawk 2.4.8
*Plane Version : 4.2
*RC Model : Radiolink T8FB
*RC Receiver : Radiolink R8EF


When i direcly connect servos to receiver (R8EF) and use RC their rotation is complete
When i use Pixhawk and connect receiver to RCIN… their rotation is not complete (very less degree of freedom)
In Mission Planner Radio Calibration all 8 channel show 1000-2000 range but when i move towards Servo Output tab some channels show (as shown in images bwlow)
