RC input Aileron missed

I’ve been trying to calibrate my futaba RC in mission planner , but noticed data of RC input Aileron missed , I double checked wiring all into input rail (input number 0 on APM 1.0 ) and its OK , but I don’t know why can’t read by mission planner configuration wizard ,
is there anyplace in source code that should be checked ? I used Arducopter version 3.2.1
any hint really appreciated
